Economic Growth: Advances in Analysis Methodologies and Technologies
SpringerBriefs in Applied Sciences and Technology
SpringerBriefs present concise summaries of cutting-edge research and practical applications across a wide spectrum of fields. Featuring compact volumes of 50 to 125 pages, the series covers a range of content from professional to academic. Typical publications can be: • A timely report of state-of-the art methods • An introduction to or a manual for the application of mathematical or computer techniques • A bridge between new research results, as published in journal articles • A snapshot of a hot or emerging topic • An in-depth case study • A presentation of core concepts that students must understand in order to make independent contributions SpringerBriefs are characterized by fast, global electronic dissemination, standard publishing contracts, standardized manuscript preparation and formatting guidelines, and expedited production schedules. On the one hand, SpringerBriefs in Applied Sciences and Technology are devoted to the publication of fundamentals and applications within the different classical engineering disciplines as well as in interdisciplinary fields that recently emerged between these areas. On the other hand, as the boundary separating fundamental research and applied technology is more and more dissolving, this series is particularly open to trans-disciplinary topics between fundamental science and engineering.

About This Book
This book analyses the economic growth frameworks worldwide and assesses interrelationships between economic evolution, life cycle sustainability assessment approaches and new technologies in the framework of the digital transition. In other words, it intends to bring more insights into the world’s economic dynamics and sustainability dimensions. Additionally, it aims to highlight how life cycle methodologies and artificial intelligence can better support different actors for more sustainable economic growth. Readers of the book benefit, for example, from diverse perspectives on the contributions of evaluation methodologies and digital technologies to more sustainable economic growth. This is important, namely for the students, policymakers and public institutions. Economic growth will be analysed using the concepts of sigma and beta convergence from Neoclassical Theory and the Verdoorn– Kaldor law of Keynesian developments. For sustainability assessments, the methodologies associated with social life cycle assessment and life cycle cost analysis will be considered. In the context of digital technologies, special emphasis will be given to artificial intelligence approaches.

Chapter 1
Economic Growth: Sigma and Beta Convergence Processes Worldwide
Abstract The economic growth process worldwide has been subject to several disturbances with different origins. These disruptions have consequences on the economic dynamics of the countries with impacts on human living conditions and the efforts for more sustainable development. These old and new challenges call for contributions that allow for a better understanding of the current contexts, namely in terms of economic evolution and how the interactions between diverse nations have been affected. In this framework, this chapter intends to assess the convergence process worldwide, considering statistical information from the World Bank for the gross domestic product (GDP) per capita and the last decades. To achieve these objectives, the developments from the Neoclassical Theory were considered, specifically those related to the sigma and beta convergence approaches. To better support the methodologies taken into account, structural breaks were also tested. The findings obtained highlight the differences in the dynamics of economic growth in distinct sub-periods over the last decades. Keywords World bank · Structural breaks · Panel data · Neoclassical theory
1.1 Introduction Economic growth worldwide depends on several factors, some of them are already clearly identified in the scientific literature, such as trade. Trade openness may contribute, in certain conditions, to reduce poverty [1]. A concern of the scientific community is to identify patterns for this economic growth and try to understand if these frameworks present dynamics of convergence, or divergence, between the regions and countries. Sigma and beta convergence concepts are among the approaches considered to assess these contexts. The GPD per capita is the variable often considered to analyse the trends of convergence. Nonetheless, these sigma and beta concepts have been also used to assess the convergence in other variables [2] and indicators [3]. Sometimes these approaches are combined with different models and methodologies [4], © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023 V. J. P. D.

including spatial autocorrelation methods [5], welfare indices [6] new techniques [7] and environmental efficiency [8]. This convergence analysis has been carried out in some cases for the whole economy and in other circumstances by sectors [9], branches [10] and activities [11]. In these phenomena of convergence, the policies designed by the governments and the international organisations have their impacts. This is particularly relevant in economic unions, such as the European Union, where European policies have great influence on the socioeconomic dynamics of the member-states and the respective processes of convergence [12]. This is visible, for example, in the frameworks of European higher education [13]. But, the economic policies and the respective funds’ transfer of the governments worldwide are also crucial to improve the development in regions with greater difficulties [14]. External shocks, such as the financial crisis of 2008/2009, also have their impacts on the economic growth dynamics and, consequently, on the processes of convergence, or divergence, between regions and countries [15]. Another issue in these economic growth dynamics is the discussion about whether convergence is absolute or conditioned to specific particularities of regions and countries, namely in terms of human capital [16]. The signs of convergence, or divergence, depend too on the periods of assessment considered [17] and on the approaches taken into account [18]. Considering the frameworks described before, this research aims to analyse the process of convergence worldwide, considering the Neoclassical Theory developments [19] and the sigma and beta convergence concepts [20, 21]. To achieve these objectives, statistical information was considered for the GDP per capita from the World Bank database [22]. Some countries were removed because of the lack of data. The speed of convergence was calculated following the study of Tondl [23]. For the regressions and statistical analyses carried out, panel data approaches were taken into account [24–26], as well as the procedures proposed by the Stata software [27–29]. For a better understanding of the contexts analysed, unknown breaks were tested through the Quandt likelihood ratio (QLR) test [30–32]. For the literature review, the Web of Science Core Collection database was consulted [33].
1.2 Data Analysis and Sigma Convergence In general, the GDP per capita increased continuously worldwide over the period 2000–2021, with the exception of the years associated with the world shocks related to the global financial crisis and the pandemic COVID-19 (Fig. 1.1). Figure 1.2 reveals signs of structural breaks (QLR test) for this variable in 2018. These findings, for this time series, need to be analysed deeper in future research.

The sigma convergence for the world GDP per capita, assessed through the coefficient of variation, shows trends of convergence until 2009 and after until 2020 (Table 1.1). These outcomes highlight the disruptions promoted by the external shocks associated with the financial crisis and COVID-19 in the convergence tendencies verified over the period 2000–2021 for this variable. Figure 1.3 presents evidence of structural breaks for the coefficient of variation of the world GDP per capita in the year 2016. Luxembourg, Macao SAR (China), Qatar, Bermuda, Singapore, United Arab Emirates, San Marino, Brunei Darussalam, Switzerland, Ireland and Norway are some of the countries with the highest averages, across the period 2000–2021, for the world GDP per capita (Table 1.2). Romania, Argentina, Chile, Malaysia, Kazakhstan, Antigua and Barbuda, Uruguay, Mexico, Bulgaria and Mauritius of some of the nations with intermediate averages for the GDP per capita in the period considered (Table 1.3). The following countries are some of those with the lowest averages (Table 1.4): Eswatini; Vietnam; Bolivia; Angola; Philippines; Morocco; Samoa; Cabo Verde; and Tonga.

There are signs of structural breaks for the world GDP per capita growth rates, over 2000–2021, in 2016 (Fig. 1.4). These results for the structural breaks with the QLR test need further assessment in future research.

1.3 Results for the Beta Convergence Considering the results obtained in the previous section for the years 2009 and 2020 (with the data analysis and the sigma convergence) and for the years 2016 and 2018 (with the QLR test), a regression with the convergence model was carried out taking into account dummies variables for these years. These findings for the model with panel data are those presented in Table 1.5. The results found confirm disturbances in 2009 and 2020, but not in 2016 and 2018. On the other hand, there is no beta convergence worldwide for the period 2000–2021, considering that the coefficient of convergence has no statistical significance. There is not also evidence of beta convergence for the period 2000–2008 (Table 1.6) and for the period 2009–2019 (Table 1.7). The signs of beta convergence appear in the period 2009–2020 (Table 1.8) and 2009–2021 (Table 1.9). In these models, the dependent variable is the GDP per capita growth rate.

1.4 Discussion and Conclusions

1.4 Discussion and Conclusions This research aimed to analyse the economic growth dynamics worldwide. For that, the convergence tendencies of the world GDP per capita over the period 2000–2021 were assessed, considering data from the World Bank. This statistical information was analysed through the models of the Neoclassical Theory and the respective concepts of sigma and beta convergence. The possibility of existing structural breaks in the time series was also tested with the QLR test. In the regressions, the methodologies associated with the panel data were taken into account. One of the focuses of the scientific literature about economic growth is to understand if the economic growth worldwide follows convergence/divergence trends among regions inside the countries, nations and parts of the world. Sigma and beta convergence are concepts often present in the studies related to the convergence assessments and a relevant part of the literature includes in the research the GDP per capita. Nonetheless, other variables and methodologies have been considered. The policy instruments, the respective support programmes and the international organisations play here a fundamental role in territorial cohesion worldwide. The external shocks, particularly those that occurred with the global financial crisis and the COVID-19 pandemic, had their impacts on the dynamics of economic growth. The impacts from the external shocks verified in the last decades are visible in the data analysis and the sigma convergence assessment for the entire sample considered. In any case, the impacts on the reduction of the GDP per capita seem to be greater with the pandemic than with the global financial crisis; however, the consequent signs of divergence look proportionally lower in the COVID-19 context. Of course, more data about the consequences of the pandemic are needed, but from this analysis, it appears that the implications of the global financial crisis had proportionally a greater impact on the divergence process worldwide. To test the potential existence of structural breaks in the times series, a previous regression with variable dummies and panel data was carried out that confirmed the presence of breaks in 2009 and 2020. Taking into account, these findings several regressions were performed for different sub-periods that revealed the existence of convergence tendencies in 2009–2020 and 2009–2021. In terms of practical implications, more statistical information is needed, particularly for more recent years, to better assess the impacts of the COVID-19 pandemic on the economic growth dynamics, but seems that the disruptions promoted by the global financial crisis were proportionally greater than by the pandemic. In any case and despite the need for more assessments to confirm these findings, these two external shocks had impacts on the evolution of the GDP per capita worldwide and consequently on the dynamics of economic growth. These results suggest the need for adjusted policies to deal with the respective consequences on the population’s well-being. For future research, it could be interesting to investigate the possibility of the existence of convergence clubs between countries.

Clubs of Convergence: Insights from the Main Groups of Countries
Abstract The dynamics of economic growth present differences in several sub-periods of the last decades and specific world regions. This evidence for groups of countries seems to show signs of clubs of convergence where the economic growth in some groups follow a trend that is distinct from the tendencies presented in other contexts. A deeper interpretation of these scenarios may bring relevant contributions to identify weaknesses and strengths, particularly for economies with greater development difficulties. In this context, it is aimed in this chapter to highlight the dynamics of convergence in the world regions and a specific sub-period over the last decades. For that, statistical information from the World Bank was considered. These data were analysed through approaches related to sigma and beta convergence. Panel data methodologies were considered for the regressions carried out and, for a better understanding of these processes, catch-up rates were also calculated. The results found show constraints verified in some world regions that may provide relevant insights for future research and policy design.

2.1 Introduction International trade plays a fundamental role in the performance of the economic growth of countries and regions, including in the processes of convergence, or divergence, between countries, particularly in the European Union [1]. These processes of convergence worldwide involve phenomena of catching-up among poor and rich countries or regions. Sometimes economies converge to the same steady state and, in other contexts, different economies with different characteristics converge to different steady states, which reveals the existence of convergence clubs. In these circumstances, some economies converge to the same steady state which is different from those to which other economies eventually converge. This presence of convergence clubs was found, © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023 V. J. P. D.

for example, in the African framework [2] and nations [3]. These clubs were too found for the human capital in China [4] and in the contexts of East Asia [5]. The assessments performed to show if the economies converge, or divergence, have been carried out at national and regional levels [6], and for the different world contexts, including between members of regional economic integration organisations, such as the Association of Southeast Asian Nations (ASEAN) [7]. These analyses also have considered the new approaches developed by the scientific community [8]. The spatial models are among the recent developments to extend the original methodologies considered for the economic growth investigation [9]. The consideration of spatial dependence may be particularly important in the convergence analysis [10]. These dynamics of economic growth and the associated processes of convergence, or divergence, are impacted by the world events, such as the global financial crisis, favouring some economies and harming others [11]. Considering these contexts, this chapter intends to analyse the processes of convergence worldwide, considering the developments from the theory [12], the sigma and beta approaches [13, 14] and the contributions of Islam [15] for the models with panel data. The possibility of the existence of convergence clubs [16, 17] was assessed, testing the sigma and beta convergence in groups of countries created through cluster analysis. For a deeper analysis of the processes of convergence, catch-up rates were calculated [18], as well as the speed of convergence [19]. For the panel data regressions, the Hoechle [20], Torres-Reyna [21] and Stata software [22–24] procedures were taken into account. For the literature survey, the Web of Science [25] database was used. The data were obtained from the World Bank [26]. Some nations were excluded due to the availability of statistical information.
2.2 Sigma Convergence and Catch-Up Rates The results for the sigma convergence of the world GDP per capita, over the period 2009–2020, show signs of divergence among 2009 and 2011, some convergence in 2012, divergence in 2013 and after convergence trends until 2020 (Table 2.1). In any case, there is evidence of a strong contraction of the GDP per capita in 2020, as a consequence of the contexts associated with the COVID-19 pandemic (Fig. 2.1). The years 2015 and 2020 present the lowest values for catch-up rate means, revealing that, on average, the gap between each country and the world-weighted average decreased in these years (Fig. 2.2). Some of the countries with the highest catch-up rate averages, across the period taken into account (2009–2020), for the world GDP per capita are the following (Table 2.2): France; Sint Maarten (Dutch part); Australia; Ireland; Libya; Equatorial Guinea; Sweden; Germany; Canada; UK; Greece; and Italy. Azerbaijan, Afghanistan, Brazil, Luxembourg, Malawi, West Bank and Gaza, Mozambique, Congo (Dem. Rep.), Niger, Solomon Islands, Sierra Leone and Comoros are some of the nations with intermediate averages for the catch-up rates (Table 2.3). The lowest catch-up

rate averages appear, for example, in the following countries (Table 2.4): Bhutan; St. Kitts and Nevis; Indonesia; Croatia; Brunei Darussalam; Belarus; Vietnam; Bosnia and Herzegovina; Thailand; Moldova; and Chile. The catch-up rate averages are negative for the countries with the intermediate and lowest values, showing that the gap in the GDP per capita between the respective countries and the world-weighted average decreased in the period considered.

2.3 Findings for Cluster Analysis and Beta Convergence To analyse the existence of convergence clubs among the investigated countries, four clusters were identified through cluster analysis for the GDP per capita. On average, the GDP per capita increases from clusters 1 to 4. The results of the convergence model with panel data (the dependent variable is the GDP per capita growth rate) for clusters 1, 2, 3 and 4 are those presented, respectively, in Tables 2.5, 2.6, 2.7 and 2.8. The speeds of convergence are, respectively, the following: 15%; 31%; 13%;

and 49%. The convergence is stronger between the countries with higher GDP per capita averages. The poorer countries continue to deserve special attention from governments and international organisations.
2.4 Discussion and Conclusions This chapter proposed to analyse the existence of convergence clubs worldwide, over the period 2009–2020, considering statistical information from the World Bank for the GDP per capita. These data were analysed with the concepts of sigma and beta convergence and approaches (catch-up rates between each country and the weighted average for the countries considered) to assess the presence of catching-up processes. Panel data methodologies were taken into account for the results obtained with the regressions. In the processes of convergence, it is expected that occur phenomena of catchingup between the poor and rich countries/regions. At the beginning of the convergence theory, the idea was that all countries would tend to converge for the same steady state and later appeared the hypothesis of the existence of convergence clubs, where it was admitted that some countries may converge to a different steady state from other countries with distinct characteristics and conditions. The findings for the sigma convergence reveal that, in general, there are signs of convergence until 2020 and the data analysis shows a strong contraction of the GDP per capita with the COVID-19 pandemic. Additionally, the catch-up rates averages were negative in 2020, showing that the gap between each country and the world decreased. In fact, the beginning of the world crises seems to be characterised by periods of convergence, the problem appears to occur when the countries internalise the consequences of the shocks and in the recovery processes. The regressions carried out for the different world clusters of countries (obtained considering the values of GDP per capita with cluster analysis methodologies), over the period 2009–2020, show that the speed of convergence is greater for clusters 2 and 4 (the GDP per capita averages increase from cluster 1 to cluster 4). This means that the poorer countries deserve special attention from the national and international communities. In terms of practical implications, the results highlight the impacts of the COVID19 pandemic on the economic growth dynamics. On the other hand, the findings found for the catching-up process and the speed of convergence call for special attention, particularly with the poorer countries. In terms of policy recommendations, it is suggested to design more programmes of financial assistance for countries with greater economic difficulties to support them to overcome the consequences of external shocks. For future research, it could be relevant to try understanding the effects of other variables, particularly those associated with human capital, on these convergence patterns.

World Trends: Differences and Similitudes Between Absolute and Conditional Convergence
Abstract The world economic growth and the respective trends of convergence/ divergence are influenced by several factors which make these processes different worldwide in the function of the specific conditions of each context. For example, the Endogenous Growth Theory suggests that the processes of convergence are not unconditional and there is not only one steady state, but there are several steady states and the convergence trends are conditional and depend on the influence of certain variables, specifically those related to human capital. Considering these perspectives, this study aims to assess the processes of conditional convergence worldwide, taking into account data associated with the gross domestic product (GDP) per capita and variables related to human capital. This statistical information was assessed through approaches associated with the sigma and beta convergence and panel data. The insights obtained reveal that, in fact, the indicators related to human capital may play a determinant role in the convergence tendencies in some circumstances and over the period considered.

3.1 Introduction A usual discussion in the scientific literature, particularly in the economic one, about the processes of convergence is if these frameworks have patterns of absolute or conditional convergence. In other words, the question is if the economies converge for the same steady state independently of their characteristics, or if the convergence is conditioned to some specific particularities, specifically the human capital. These were some of the aspects, between others, taken into account by Cermeno [1] for the Mexican states. The absolute and conditional convergences were also tested for the following contexts: British regions [2]; renewable energy use in European countries [3]; cities and counties in China [4]; total factor productivity in developing and developed countries [5]; Western Balkan countries [6]; groups of countries with and without fossil fuel endowments [7]; between the former © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023 V.

socialist countries [8]; Eastern Partnership Countries and the European Union tendencies [9]; Indian states [10]; European Union countries [11]; and North and South of Cyprus [12]. Another not consensual discussion is about the adequacy of the methodology considered to test the hypothesis of absolute and conditional convergence [13]. This divergence in the opinions about the patterns of economic growth and the methodologies used is old and, in some cases, is based, for example, on different perspectives about the returns to scale. The idea of absolute convergence is based on the developments of the Neoclassical Theory [14], considering assumptions of decreasing returns to scale and that the poorer economies have economic growth rates higher than the richer ones and in this way, countries and regions converge for the same steady state. Nonetheless, the Endogenous Growth Theory demonstrated that economic growth is dependent on the characteristics of each economy and in this way is conditioned by the human capital stock and by technological change and innovation [15, 16]. In these frameworks, it is expected to find increasing returns to scale and endogenous technological change [17, 18]. From this perspective, this study aims to analyse the conditional convergence of the GDP per capita, considering the sigma and beta concepts [19, 20], panel data methodologies [21–26] and statistical information from the World Bank [27]. Some countries were not considered because data for some years of this period were missing. The data considered are those associated with the GDP per capita and the following proxies for the human capital stock and skills: school enrolment, secondary (% gross); school enrolment, tertiary (% gross). The Web of Science [28] database was considered for the literature analysis.
3.2 Sigma Convergence and Data Analysis There is a clear trend of sigma convergence over the period considered (2013–2020) for the world gross domestic product per capita, that were more accentuated between the years 2013 and 2015 (Table 3.1). There are also signs of convergence for the world school enrolment, secondary (% gross), particularly after 2016 (Fig. 3.1). The world school enrolment, tertiary (% gross) presents different tendencies of convergence. In any case, it occurs for this variable, with disturbances in 2015 and 2028 (Fig. 3.2). Greece, Australia, Turkiye, Grenada, Korea (Rep.), Puerto Rico, Finland, Belarus, Spain, USA, Singapore, Argentina and Chile are between the countries with the highest averages for school enrolment in tertiary (% gross) (Table 3.2). Some of the nations with intermediate averages for school enrolment in tertiary (% gross) are the following (Table 3.3): Kazakhstan; Fiji; Georgia; United Arab Emirates; Brazil; Hungary; Armenia; Romania; San Marino; Slovak Republic; Bahrain; and China. Ghana, Aruba, Samoa, Cameroon, St. Vincent and the Grenadines, Bhutan,

3.3 Results for Conditional Beta Convergence with Panel Data Table 3.5 reveals the existence of absolute beta convergence (speed of convergence of about 29%) for the world GDP per capita (the dependent variable in the model considered is the GDP per capita growth rate), over the period considered (2013– 2020). These findings are confirmed in Table 3.6 for a model considering independent variables as proxies for human capital. Nonetheless, the results presented in this table exclude the hypothesis of convergence conditioned by the variables considered for human capital. The evidence of convergence conditioned by the school enrolment in tertiary (% gross) growth rate appears in Table 3.7, when the model allows for more lags in the regression, showing that the effects of human capital education on the economy are delayed in time.
3.4 Discussion and Conclusions This study intends to investigate the hypothesis of conditional convergence worldwide, particularly analysing the impact of variables related to human capital on the economic growth dynamics between world countries. For that, data from the World Bank (for the period 2013–2020) were considered for the GDP per capita and the following variables as proxies for the human capital: school enrolment, secondary (% gross); school enrolment, tertiary (% gross). This statistical information was analysed with panel data methodologies and taking into account the concepts of sigma and beta convergence. A usual discussion in the scientific literature is about if the regions and countries converge for the same steady state, following patterns of absolute convergence, or if the convergence tendencies are conditioned by specific characteristics of the economies. Another not-unanimous discussion is about the methodologies taken into account to assess the processes of economic growth. Particularly, the Endogenous Growth Theory brought new developments to support the understanding of the convergence trends found between different economies. The sigma convergence highlights trends of convergence, for the GDP per capita, over the period considered, specifically between 2013 and 2015. Signs of convergence

were also found for the world school enrolment, secondary (% gross), and the world school enrolment, tertiary (% gross). For example, among the countries with the highest averages for school enrolment in tertiary (% gross) are the following: Greece, Australia, Turkiye, Grenada, Korea (Rep.), Puerto Rico, Finland, Belarus, Spain, USA, Singapore, Argentina and Chile. The results obtained from the regressions carried out reveal that the world GDP per capita follows a pattern of absolute convergence, for the period 2013–2020, the sample used and the approaches taken into account. The variables considered as proxies for the human capital have a residual impact and the respective coefficient of regression has statistical significance only when more lags were considered for the regressions (showing some time delay in the implications). In terms of practical implications, the economic processes of convergence worldwide are, namely, present evidence of absolute convergence over the period 2013– 2020, for the sample considered and the methodologies used. It is suggested more studies with other variables to test the conditional convergence in the sample considered and to test other approaches. For future research, it could be important to compare these results with those obtained with the models associated with the divergence theory.

Constant, Decreasing or Increasing Returns to Scale: Evidence from the Verdoorn and Kaldor Laws
Abstract The discussions in the scientific literature about economic growth trends are vast and not unanimous. The economic theory has different opinions about economic growth that disagree, sometimes, if the economies tend to converge or diverge over time. In fact, the Neoclassical Theory argues that the economies tend to converge for the same steady state and the Keynesian Theory defends that the processes of economic growth promote divergence between countries/regions through increasing returns to scale. In the processes of divergence, the richer economies improve their performance and the poorer countries become worse. Taking into account these contexts, this research intends to test the existence of increasing returns to scale, using data for output and employment growth. For these analyses, the approaches related to the Verdoorn and Kaldor laws were considered. The results obtained highlight the existence of increasing returns to scale in some frameworks and reveal the importance of national and international policies implementation to promote a more balanced and sustainable development. Keywords Circular and cumulative processes · Economic growth · Keynesian theory · External demand
4.1 Introduction The presence of decreasing, constant and increasing returns to scale has generated not unanimous debate in the economic literature. Particularly the Keynesian Theory argues that the economic growth trend follows processes with learning by doing and spillover effects in the presence of increasing returns to scale and promote self-reinforced circular and cumulative phenomena, where richer economies become richer and the poorer ones become worse. These contexts were explained, for example, by Kaldor [1, 2] through their laws, where the manufacturing sector is the engine of the economy and the productivity growth is endogenous and dependent on the output growth (Verdoorn law [3]). These laws were reconsidered by, for example, McCombie [4], Parikh [5] and Stoneman [6].

sector for the economy is also associated with its capacity to produce tradable goods, appearing here the manufacturing exports as a determinant variable [7]. In addition, some extended models have been considered [8]. The Verdoorn–Kaldor laws have been taken into account for studies related to the following issues worldwide: European regions [9]; Turkish contexts [10]; open economy Stock-Flow Consistent models [11]; Chinese framework [12]; Peruvian manufacturing sector [13]; Portuguese agroforestry activities [14]; and Australian economy [15]. The systematic review of Barreto et al. [16] highlighted some gaps in the literature about the Kaldor developments in the Pacific Alliance and the Association of Southeast Asia Nations, namely those related to the lack of research that comparatively assess the determinants of Kaldor and the scarcity of studies about convergence, or divergence, among nations and trade unions. This literature survey shows that the Kaldor laws were the target of criticism and diverse studies reconsidered these laws, proposing, in some cases, alternative models and approaches trying to make compatible the different points of view. In any case, the developments of Kaldor have been taken into account by diverse studies as methodologies to assess the presence of increasing returns to scale. Kaldor proposed that in the Verdoorn law productivity growth should be replaced by employment growth to avoid spurious relationships. In this alternative approach, the presence of increasing returns to scale is confirmed with statistically significant and positive coefficients close to zero. In this way, this chapter proposes to estimate the relationship between the employment growth (using as proxies the following variables: total labour force; employment in industry (% of total employment); and employment to population ratio, 15+, total (%) and the output growth (gross domestic product (GDP) per capita) with panel data [17–21]. For the literature assessment, the Web of Science information was taken into account [22]. The statistical information was obtained from the World Bank [23] (some countries were excluded because of the lack of data).
4.2 Data Analysis Over the period 2014–2020, the world GDP per capita averages increased until 2019 and decreased drastically in 2020 because of the COVID-19 pandemic (Fig. 4.1). A similar pattern was found for the world labour force (total) averages (Fig. 4.2) and for the world employment to population ratio [15+, total (%)] averages (Fig. 4.4). A different trend was found for the world employment in industry (% of total employment) averages (Fig. 4.3). Qatar, Oman, Czechia, Slovak Republic, Bahrain, Lesotho, Tunisia, Slovenia, Iran (Islamic Rep.), Turkmenistan, United Arab Emirates, Belarus, Poland and Hungary are countries between those with the highest averages for employment in industry (% of total employment) (Table 4.1). The intermediate averages appear in countries such as Indonesia, Honduras, Lebanon, Brazil, Argentina, Belgium, Benin, Iraq,

4.3 Results for the Kaldor Model Taking into account the world labour force (total) growth rates as the dependent variable, Table 4.4 shows that there is evidence of strong increasing returns to scale (the coefficient of the independent variable is statistically significant and close to zero). These signs disappear when the employment in industry (% of total employment) growth rates is considered as the dependent variable (Table 4.5). Considering the importance of the manufacturing sector for the Kaldor model, these findings need deeper assessment in future research. The signs of increasing returns to scale reappeared when the employment to population ratio [15+, total (%)] growth rates were taken into account as the dependent variable (Table 4.6).
4.4 Discussion and Conclusions This chapter aims to test for the existence of increasing returns in the economic growth processes worldwide and to find signs that support the perspectives of divergence trends between the world countries defended, for example, by the literature associated with the Keynesian Theory. For that, the developments related to the Verdoorn and Kaldor laws were taken into account for regression with panel data. The statistical information was obtained from the World Bank for the period 2014–2020. As proxies for employment, the following variables were considered: total labour force; employment in industry (% of total employment); and employment to population ratio, 15+, total (%). Some of the disagreements at the basis of the discussions about if economic growth follows trends of convergence or divergence are related to the perspectives about scale economies. In fact, the authors associated with the Keynesian Theory

argue that economic growth worldwide follows patterns in the presence of increasing returns to scale, where the richer economies become richer and poorer ones become poorer. In these processes of divergence, the manufacturing sector plays a crucial role, considering its capacity to produce tradable goods, highlighting in this way the importance of international trade for the economic dynamics and the differences among countries. The COVID-19 pandemic had a relevant impact on the GDP per capita worldwide, as well as on the labour force and world employment. In any case, world employment in the industry seems to follow a different pattern that may be better explored in future research. Among the countries with the highest averages for employment in industry (% of total employment) are, for example, the following: Qatar, Oman, Czechia, Slovak Republic, Bahrain, Lesotho, Tunisia, Slovenia, Iran (Islamic Rep.), Turkmenistan, United Arab Emirates, Belarus, Poland and Hungary. The results obtained for the Kaldor model (relation between the employment growth and the output growth, where the employment is endogenous) present that there are strong signs of increasing returns to scale and this may compromise the processes of convergence in the medium and long terms. On the other hand, there are no signs of increasing returns to scale, when employment in the industry is considered. In terms of practical implications, there is evidence of increasing returns to scale in some circumstances and this may compromise the trends of convergence. In any case, more studies ate suggested to bring more contributions about these tendencies. More policies and programmes are needed to better support the countries with more economic weaknesses. For future research, it is suggested to analyse the contributions of other approaches and theories for these frameworks.

Circular and Cumulative Processes in Economic Growth: The Importance of the External Demand
Abstract The Keynesian Theory and the New Economic Geography defend that the economic growth processes follow trends of divergence, through self-reinforced circular and cumulative phenomena, promoted by increasing returns to scale. The Keynesian Theory explains these processes highlighting the importance of the external demand and based on the Verdoorn law, where the productivity growth is endogenous and dependent on the output growth. The New Economic Geography developments are based on the real wage differences between economies and on transport costs. Following these contexts and the current conjuncture worldwide, this chapter proposes to test the impacts of external demand and real wages (as engines of circular and cumulative phenomena) on output growth. For that, statistical information associated with output growth, exports growth and wages was considered. To analyse these data, the Thirlwall law and the developments of the New Economic Geography were taken into account. The findings identified to reveal the importance of exports and employment compensation for the economic growth patterns worldwide and the relevance of dealing with these differences to promote more sustainable development. Keywords Keynesian theory · New economic geography · Output growth · Real wages
5.1 Introduction Tradable goods and international trade appear as important variables in the Keynesian models [1], namely with the contributions of Thirlwall [2] for the Keynesian Theory through developments that later became known as the Thirlwall law. The idea is that the output growth is dependent on the export growth [3]. Thirlwall followed, for example, the research of Verdoorn [4] and Kaldor [5, 6]. These developments of Thirlwall were considered and discussed by several studies [7, 8] and generated debate [9, 10].

5 Circular and Cumulative Processes in Economic Growth
Spanish economy [12]; Portuguese and Spanish economic dynamics [13]; the economic context in Argentina [14]; government policies and exports in the growth processes [15]; the presence of structural heterogeneity [16]; Indian economy [17]; Kazakhstan context [18]. On the other hand, the New Economic Geography reinforced the idea of increasing returns to scale and the existence of circular and cumulative processes, where real wages and transport costs are some of the most important variables. In summary, the economies with higher real wages attract more population and economic activity and this is promoted by the intention of being closer (population and economic sectors) to save transport and communication costs [19, 20]. This creates self-reinforced processes of agglomeration, where the economic activity and population tend to concentrate in poles. Generally, two poles are generated, one stronger and a second weaker. This explains why the economic sectors and the population are agglomerated in big cities and regions inside the countries and worldwide expressions such as core-peripheral countries are found. The only forces of anti-agglomeration come from sectors dependent on immobile production factors, such as agriculture (dependent on immobile land). Considering these perspectives from the literature [21], this chapter intends to bring more contributions about the interrelationships between the output (gross domestic product (GDP) per capita) growth, the external demand [exports of goods and services (annual % growth)] and the wages [compensation of employees (% of expense)]. The statistical information for these variables was obtained from the World Bank [22] (some nations were removed, because statistical information for some years was missing), and these data were analysed through panel data approaches, following the procedures proposed by Hoechle [23], Torres-Reyna [24] and the Stata software [25–27].
5.2 Data Assessment The COVID-19 pandemic promoted several disruptions worldwide in different domains, including in the world GDP per capita (Fig. 5.1). These impacts are also visible in the world compensation of employees (% of expense) averages (Fig. 5.2) and world exports of goods and services (annual % growth) averages (Fig. 5.3). Nonetheless, there were some signs of a downward trend in these variables in previous years. Some of the nations with the highest averages for the exports of goods and services (annual % growth) are the following (Table 5.1): Ireland; Mongolia; Madagascar; Serbia; Cambodia; North Macedonia; Romania; Cyprus; Kiribati; Philippines ; Armenia; Poland; Lithuania; Moldova; Malta; Australia; Hungary; and Morocco.

5 Circular and Cumulative Processes in Economic Growth
5.3 Findings Considering the Developments of Thirlwall and Those of the New Economic Geography The developments of Thirlwall suggest that the external demand (exports) of tradable goods is the engine of economic growth. These developments become known in the economic theory as the Thirlwall law. The subjacent idea is that output growth is dependent on international trade. Following these perspectives, a regression was carried out considering the world GDP per capita growth rate as the dependent variable and the exports of goods and services (annual growth rate) as the independent variable (Table 5.3). The results confirm the positive and statistically significant relationship between these two variables. The New Economic Geography emphasise the importance of wages to promote circular and cumulative processes of agglomeration of the population and economic activities. The findings presented in Table 5.4 show that, in fact, the GDP per capita growth rate positively impacts the compensation of employees (% of expense) growth rate. For the world GDP per capita growth rate as dependent variables, the results were not statistically significant, showing that the impacts are from the GDP per capita to the compensations of employees.
5.4 Discussion and Conclusions This research aims to investigate the relationships between international trade and the wages of the workers with the output of the countries. To achieve these proposals, developments associated with the Keynesian Theory (namely those related to the Thirlwall law) and the New Economic Geography were taken into account. These theories predict increasing returns to scale in the dynamics of economic growth and consequently tendencies of divergence among regions and countries, through selfreinforced processes of circular and cumulative phenomena. Data from the World Bank were considered for the period 2013–2020 and the following variables: GDP per capita; exports of goods and services (annual % growth), as proxies for the external demand; and compensation of employees (% of expense), as proxies for the wages. From the theory, it is expected that the external demand (the exports) promotes positive externalities on the output (some of the explanations for these processes become known in the theory as the Thirlwall law). In practice, these assumptions argue that output growth is endogenous and dependent on international trade growth and subsequently through the Verdoorn–Kaldor laws this has implications on the competitiveness of the economies. On the other hand, the New Economic Geography defends that the population and economic activity tend to agglomerate to save transport and communication costs.

The pandemic impacted the world compensation of employees (% of expense) averages (Fig. 5.2) and world exports of goods and services (annual % growth) averages. These trends, however, seem to come already from previous years. Ireland, Mongolia, Madagascar, Serbia, Cambodia, North Macedonia, Romania, Cyprus, Kiribati, Philippines, Armenia, Poland, Lithuania, Moldova, Malta, Australia, Hungary and Morocco are some of the countries with the highest averages for exports of goods and services (annual % growth). The regressions carried out with panel data, to try to test the assumptions related to the Thirlwall law, show that, in fact, the GDP per capita growth rate is endogenous and dependent on the exports of goods and services (annual growth rate). On the other hand, considering the New Economic Geography, the findings reveal that the compensation of employees (% of expense) growth rate is dependent on the world GDP per capita. In terms of practical implications, international trade is determinant for the processes of economic growth worldwide and these dynamics impact employment conditions, namely the compensation of employees dynamics. It is recommended special attention, by the policy and decision-makers, about the trade dynamics and employment conditions in the design of policy instruments and measures. For future research, it could be interesting to bring more insights into economic growth and sustainability.

Interrelationships Between Economic Growth and Sustainability: Highlights from the Literature
Abstract The great discussions currently are about how to make compatible economic growth and sustainability. In other words, the big challenge for the next years is to identify strategies that promote economic growth and human well-being without compromising the environment and the future of the planet. This is, in fact, a hard task for the current and next generations. The needs of humanity for more food and employment are in an increasing trend and these frameworks call for continuous economic growth worldwide, but these tendencies are supported often compromising the availability of resources for the next generations. The objective of this research is to bring more insights from the scientific literature about the interrelationships between economic growth and sustainability. For that, several documents, obtained from the Scopus database and related to the issues here addressed, were considered. These documents were analysed through bibliometric approaches and following the VOSviewer software procedures. With this research, several contributions for more sustainable economic growth were presented. Keywords Bibliometric analysis · Systematic review · VOSviewer · Scopus database
6.1 Introduction The manufacturing sector plays a fundamental role in economic growth, but, in some circumstances and sectors, the industry has relevant impacts on climate change and, consequently, on sustainability. These contexts call for a deeper understanding of the supply chains to better identify approaches for more sustainable development [1]. The sustainability of the tourism sector also has aroused the curiosity of the scientific community [2], including its relationship with water quality [3] and environmental degradation [4].

6 Interrelationships Between Economic Growth and Sustainability …
Public policies are crucial to make compatible the different dimensions of sustainability. This is true for the Mexican frameworks [5] as it is for other frameworks worldwide. Renewable energy policies, for instance, may be interesting instruments to promote economic growth without compromising the environmental dimensions [6]. The needs for continuous, and ever-increasing, economic growth create additional pressures on the available resources, specifically on the water [7], and bring new concerns about greenhouse gas emissions. This is particularly worrying in the agricultural sector, where the concerns with food security may compromise, in certain cases, the goals to mitigate the carbon emissions. The understanding of the relationships between food security and carbon emissions is crucial to control global warming [8]. Land tenure is another dimension to take into account in the discussions about food security [9]. If economic growth creates difficulties to deal with climate change, global warming also impacts economic asymmetries [10]. Another current concern for the governments is the sustainability of urban infrastructures and the associated changes verified in the last decades. In fact, currently, there is a continuous migration of the population from the rural areas to the cities [11], creating problems of desertification in some regions and difficulties of overpopulation in the cities [12]. Of course, there are differences in these phenomena worldwide, but this is a real trend verified in many nations. The new technologies may bring new perspectives for a greener economy [13]. Considering this literature survey, this chapter aims to highlight insights from the literature about the relationships between economic growth, sustainability and climate change worldwide. For that, a bibliometric analysis and systematic review [14] were carried out based on 959 documents obtained on a search performed on 17 May 2023 in the Scopus [15] database for the following topics: “economic growth”; and “sustainability”; and “climate change”. For the bibliometric analysis, the VOSviewer software procedures were followed [16–18]. For the bibliometric analysis, bibliographic data were considered, as well as the following links: cooccurrence; bibliographic coupling; and co-citation. The metrics were obtained with full counting and the next conditions: 1 as the minimum number of occurrences of a keyword; 1 as the minimum number of documents of a country; 1 as the minimum number of documents of an organisation; 1 as the minimum number of citations of an author; 0 as the minimum number of citations of a document; and 1 as the minimum number of citations of a source. To identify the top items (keywords, countries, organisations, authors, documents and sources), the total link strength metric was taken into account [19].
6.2 Bibliometric Analysis
83
6.2 Bibliometric Analysis The keywords with the highest values for the total link strength metric (related to the number of documents where they appear together) are the following (Table 6.1): climate change; sustainable development; sustainability; economic growth; economics; and economic development. These keywords highlight a clear concern with the impacts of carbon dioxide on the relationships between economic growth, sustainability and climate change. On the other hand, this group of keywords shows that, sometimes, different expressions are used to express the same context. The keywords with higher relatedness present also a relevant number of occurrences (Fig. 6.1) and average citations. China, Turkey, Pakistan, UK, Malaysia, USA, Nigeria, Australia, India and Spain are the countries of affiliation of the authors with the biggest total link strength (Table 6.2). The top 10 countries of affiliation have also an important number of documents (Fig. 6.2) and citations. Between the organisations with the greatest values for the total link strength appear the following (Table 6.3): Faculty of Economics Administrative and Social Sciences, Istanbul Gelisim University; Institute of Climate Change, Universiti Kebangsaan Malaysia; School of Management and Economics, Beijing Institute of Technology; Australian National University’s, Fenner School of Environment and Society; and Australian Griffith University. Some of the top 10 organisations have also a relevant number of documents (Fig. 6.3) and citations.

Practices to increase the environmental sustainability
Some economic sectors and activities, such as manufacturing, are fundamental for economic growth, but bring also, in some circumstances, negative impacts on climate change and environmental sustainability. The national and international policies and institutions have here a crucial role to make more compatible economic growth with sustainable development. The main challenge for the stakeholders is to make compatible the needs of economic growth, because of the employment (for example), and the preservation of the planet’s natural resources. Climate change, sustainable development, sustainability, economic growth, economics and economic development are some of the keywords found in the documents analysed, revealing concerns, for example, with the impacts of carbon dioxide emissions. Some of the relevant countries of affiliation of the authors for the network assessed (taking into account the approaches followed) are the following: China; Turkey; Pakistan; UK; Malaysia; USA; Nigeria; Australia; India; and Spain. The relevant sources are, for example, the following: Energy policy; Energy; Environmental Science and Pollution Research; Sustainability; and Science.

The literature review based on the bibliometric analysis highlight, to make compatible economic growth with sustainability (mitigating climate change) the importance of the use of renewable energy, promote innovation, consider the artificial intelligence approaches, promote urban sustainability and design adjusted policies and programs. In terms of practical implications, it seems that there is a field to be explored about these topics, particularly including other domains from the science and extending the network to other countries and organisations. In terms of policy recommendations, it is suggested to create conditions and programs to promote more studies on topics less explored in countries with fewer research dynamics and generate conditions to make more visible some work already realised and not published. For future research, it could be relevant to analyse the relationships between sustainability and the life cycle tools.

Sustainable Development: Contributions from Life Cycle Cost Analysis
Abstract To promote more sustainable developments, several approaches have been developed to support more adjusted assessments and the processes of policy design by governments and international organisations. The life cycle assessment and the life cycle cost analysis are examples of methodologies used to better understand the impacts of products and investments on sustainability. Nonetheless, the scientific literature shows that there is a field to be explored about the contributions of the life cycle cost analysis for more sustainable development. Considering these motivations, this research proposes to highlight contributions from the literature about the interrelationships among sustainability and life cycle cost analysis. To achieve these objectives, various documents from the Scopus database were considered for topics associated with these issues. These documents were assessed through co-citation links and considering authors, sources and documents as items. The top documents identified through this bibliometric analysis were taken into account for a survey of the literature. The results obtained provide relevant insights on the relationships between sustainable development and the life cycle cost analysis.

7.1 Introduction The life cycle assessment and life cycle cost(ing) analysis/assessment are among the approaches considered in the sustainable development investigation, as parts of the life cycle sustainability assessment [1]. The life cycle cost analysis is an interesting methodology to assess the economic dimensions of products and processes, supporting the stakeholders to follow more sustainable developments [2]. The use of life cycle methodologies in the agricultural sector is increasing [3], but there is still some work to do, namely because the life cycle cost analysis is not yet harmonised for agri-food productions [4].

7 Sustainable Development: Contributions from Life Cycle Cost Analysis
The scientific literature has analysed the consideration of the life cycle cost analysis in the following topics: pavement networks [5]; construction industry [6, 7]; wastewater treatment [8]; building life cycle evaluation [9]; gold mining activities [10]; solid oxide fuel cells [11]; and green roofs [12]. The scientific literature has brought relevant insights about the relevance of bibliometric analysis as support for systematic reviews. In fact, the bibliometric approaches provide adjusted information to more objectively identify the documents to be surveyed through systematic review [13, 14]. There are still, however, some gaps in the literature about the interlinkages between sustainable development and life cycle cost analysis, showing that there is a field to be explored about the contributions of the life cycle costing assessment for sustainability. Considering these motivations, this research proposes to bring more insights into the contributions of the life cycle cost analysis for sustainable development worldwide and the different sectors. For that, 1489 documents were considered. These documents were obtained from the Scopus [15] database, in a search that was carried out on 17 May 2023, for the following topics: “sustainable development”; and “life cycle cost*”. These studies were analysed through bibliometric analysis, following the VOSviewer procedures [16–18], which was taken into account as support for a literature survey [19]. To identify the top items analysed (all keywords, countries, organisations, authors, documents and sources), it was followed the approaches considered by Martinho [20], for example. In the figures presented in the remaining structure of this chapter, the distance between items represents the relatedness. On the other hand, the dimensions of the circles and labels represent the number of occurrences for the co-occurrence links, the number of documents for the bibliographic coupling links and the number of citations for the co-citation links [17].
7.2 Bibliographic Data Assessment Figure 7.1 and Table 7.1 highlight the keywords with the highest occurrences and total link strength, respectively. Table 7.1 also shows that keywords with the biggest values for the total link strength metric have a too important number of occurrences and average citations. These keywords reveal the relevance of the life cycle analysis tools to better support decision making and promote more sustainable development. USA, China, Germany, Italy, UK, Spain, Australia and Portugal are the countries with more relatedness with other countries (the relatedness for bibliographic coupling links is based on the number of references they share) and with a relevant number of documents and citations (Fig. 7.2 and Table 7.2). The top 10 organisations with the greatest values for the total link strength are those presented in Table 7.3. These organisations of affiliation of the authors are, for example, from Spain, Brazil, Germany and Hungary. The dimensions of the circles and labels presented in Fig. 7.3 are related to the number of documents of each item (organisation) and the proximity of the items is associated with the relatedness.

Fig. 7.1 All keywords as items and co-occurrence links for the topics: “sustainable development”; and “life cycle cost*”
Figure 7.4 and Table 7.4 exhibit the metrics for the cited authors considering cocitation links. The authors with the highest values for the total link strength are, for example, the following: Heijungs, R.; Frangopol, D.M.; Finkbeiner, M.; Hunkeler, D.; Azapagic, A.; Traverso, M.; Huppes, G.; Kucukvar, M. For the co-citation links the relatedness is based on the number of times the items are cited together. The dimension of the circles and labels in Fig. 7.4 symbolises the number of citations and the proximity represents the relatedness. Table 7.5 shows the top 10 documents for bibliographic coupling links (relatedness based on the number of references the items share and in this way, it is expected that they are related to the same issue). The sources with the highest total link strength and relevant citations (Fig. 7.5 and Table 7.6) are related to energy, sustainability, life cycle assessment and cleaner production. The majority of the top 10 sources are associated with energy, such as: Energy; Energy Build.; Appl. Energy; Energy Policy; Renew. Sustain. Energy Rev.; and Energy Build. These findings reveal that there is a field to be explored in other domains.

7 Sustainable Development: Contributions from Life Cycle Cost Analysis
7.3 Contributions from the Literature for the Topics Analysed The contributions presented in Table 7.7 highlight the importance of the different life cycle tools (life cycle analysis, life cycle cost analysis and social life cycle analysis) for the sustainability assessment. However, these tools are still under development, particularly because of difficulties associated with the lack of data (namely for the economic and social dimensions). On the other hand, a standardisation is missing for these approaches and respective indicators, which brings additional constraints when it is intended to promote some comparability. More research about these topics may bring added value, specifically to integrate the different life cycle tools in a comparable framework. Table 7.7 Insights from the literature Documents

7.4 Discussion and Conclusions This study intends to bring more insights from the literature about the contributions of the life cycle cost analysis for sustainability. In this way, a search on 17 May 2023 was carried out in the Scopus database for the topics: “sustainable development”; and “life cycle cost*”. From this search, 1489 documents were identified that were assessed through bibliography data analysis and following the VOSviewer software procedures. In this assessment were analysed keywords, countries, organisations, cited authors, documents and cited sources items from different links. The life cycle cost analysis appears in the literature as part of the life cycle sustainability assessment and has been considered to analyse the economic dimensions of products and processes. This approach has been taken into account in assessments related to the construction and related activities, for example, but there is still some work to do in other sectors and activities, particularly those associated with agricultural practices and products. The bibliometric analysis highlights some relevant (considering the approaches here considered based, specifically on the total link strength) keywords in the documents identified, such as the following: sustainable development; life cycle; costs; cost–benefit analysis; environmental impact; and sustainability. These findings highlight the importance of life cycle tools to support decision-makers. The USA, China, Germany, Italy, the UK, Spain, Australia and Portugal are some of the relevant countries. Finally, a relevant part of the top 10 sources (with the highest total link strength) is focused on the energy fields. The systematic review highlights the relevance of the life cycle tools; however, there is still some work to do, specifically to: bring more insights for the development of these tools; mitigate difficulties associated with the lack of data; standardise the indicators and approaches; create comparable frameworks among the different life cycle tools. In terms of practical implication, the bibliometric analysis and the literature review highlight the need for more research to better develop the life cycle tools, the importance of these methodologies for the sustainable development assessment and more standardisation of the associated indicators and approaches. For policy recommendations, it could be pertinent to create regulations and guidelines for the implementation of these tools in the different economic sectors and activities. For future research, it is suggested to investigate the tools to assess the social dimensions in the economic growth processes.

Social Life Cycle Assessment: Relationships with the Economic Growth
Abstract The social impacts of the economic growth processes are often underestimated, sometimes because of the difficulties in effectively assessing these implications and other times due to a scale of priorities where the economic dimensions appear with special relevance. The social life cycle assessment appears as an approach to highlight the impacts of the life cycle of the products on the social human conditions. Another question is about the various interrelationships between the social life cycle assessment and economic growth. It seems interesting to investigate how the social life cycle assessment influences economic growth and how the economic trends deal with these social analyses. In this way, this chapter investigates the several interrelationships among the social life cycle assessment and the economic growth highlighted by the scientific literature. From this perspective, several scientific documents were considered for these subjects. These documents were first explored through bibliometric analysis and after considering a literature survey for the top documents. This chapter highlights how the social life cycle assessment may contribute to a more sustainable economic development.

8.1 Introduction The social dimensions are one of the areas of sustainability that have been gaining relevance in scientific research related to sustainable development. An example of this importance is the increasing consideration in the literature of tools such as social life cycle assessment. This approach supports stakeholders in assessments related to the social impacts of products throughout their life cycle [1]. In the construction sector, for example, generally, the focus of the social life cycle assessment is on the production stage [2], ignoring other phases of the supply chain from the extraction of raw materials to the end of life of products, where the social impacts are also real and need to be taken into account. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023 V.

8 Social Life Cycle Assessment: Relationships with the Economic Growth
The social life cycle assessment is part of the life cycle sustainability analysis. These approaches need standardisation, identification of boundaries, construction of adjusted databases, development of categories to better compare studies and improve the assessment methodologies [3]. Specifically, the social life cycle assessment is a tool under development and can be considered at different levels (products, economic sectors, regions and countries) [4]. This methodology appears among the topics associated with sustainable processes, value creation and competitive advantage [5]. Four phases may be identified for this approach, particularly the following: beginning; uncertainty; development; and search for harmonisation [6]. The literature highlights the consideration of the social life cycle assessment concepts and guidelines in studies that include the following fields: production of feedstocks for biodiesel in Brazil [7]; food supply chain [8]; and circular economy [9, 10]; industry 4.0 [11]; building sector [12, 13]; municipal solid waste [14]. In summary, the social life cycle analysis may provide interesting insights for the sustainability assessments, where the new technologies associated with the digital transition may bring relevant added value. Nonetheless, more studies are needed to develop more databases and categories and improve the standardisation of the methodologies applied. In this scenario, this research proposes to bring more contributions from the literature about the relationships among the economic dimensions and the social life cycle assessment. To achieve these objectives, 347 documents were taken into account from the Scopus [15] database, on a search carried out on 17 May 2023, for the following topics: “economic”; and “social life cycle”. These studies were assessed through bibliometric analysis (following, for example, the research of Martinho [16]) and systematic review [17]. For the bibliometric analysis, the procedures proposed by the VOSviewer software were considered [18–20].
8.2 Co-occurrence, Bibliographic Coupling and Co-citation Links Analysis In general, the social life cycle assessment as a tool to analyse and promote sustainable economic growth is interrelated with the other tools for the life cycle sustainability assessment, and this is visible in the metrics presented for the top keywords in Fig. 8.1 and Table 8.1. The top 10 keywords appear in documents published between 2017 and 2019. The keyword “life cycle” is the one with the highest total link strength and seems that with the biggest number of occurrences. Germany, Italy, the USA, Spain, Brazil, France, Netherlands, China, Canada and Hong Kong are the top 10 countries with the highest total link strength (Table 8.2). These countries exhibit also important values for the number of documents and citations (Fig. 8.2 and Table 8.2). The average publication year for the documents published by the authors of these countries ranges between 2017 and 2020.

Some of these organisations have also a relevant number of documents (Fig. 8.3 and Table 8.3). The top 10 cited authors (with the highest total link strength) are those exhibited in Table 8.4, and the top 10 documents are presented in Table 8.5. Figure 8.4 shows the cited authors for co-citation links. In this figure, the dimension of the circle and labels represents the number of citations and the proximity symbolises the relatedness (number of times they were cited together). Figure 8.5 and Table 8.6 present some metrics for co-citation links and cited sources items. The cited sources with the biggest values for the total link strength are, namely the International Journal of Life Cycle Assessment and the Journal of Cleaner Production in the different versions for their designations.

8.3 A Literature Review Based on Bibliographic Data Table 8.7 shows some insights from the literature about the relationships between the following topics: “economic”; and “social life cycle”. The top 10 documents highlight the need for a better reorganisation of definitions and indicators, more studies related to these dimensions and more adjusted support for the system boundaries. Bioeconony, manufacturing and corporate social profile of companies appear as the focus of some research associated with the social life cycle analysis. On the other hand, sustainability is more than the three indices for the environmental, economic and social dimensions. Finally, the UNEP/SETAC Guidelines are presented as relevant support for the social life cycle assessment.
8.4 Discussion and Conclusions This chapter proposes to analyse interrelationships between the economic growth and the social life cycle assessment, bringing more highlights from the scientific literature published in international databases. For that, 347 documents were surveyed through bibliometric analysis with co-occurrence, bibliographic coupling and cocitation links. These documents were obtained from the Scopus database on a search carried out on 17 May 2023 for the topics: “economic”; and “social life cycle”. In this bibliometric assessment, the procedures proposed by the VOSviewer software were followed. The social dimensions have gained importance in the scientific literature associated with the sustainability domains, with increases in the consideration by the researchers of the social life cycle assessment tools. These tools are part of the life

cycle sustainability assessment and still need standardisation, the definition of boundaries, construction of databases and development of more guidelines. The social life cycle assessment has been considered in domains related to, for example, the feedstock for biodiesel, supply chains, bioeconomy, industry, construction sector and municipal waste. The bibliometric assessment highlights that some of the relevant keywords (with the highest relatedness) are the following: life cycle; life cycle assessment; sustainable development; social life cycle assessment; social life; economic and social effects; sustainability; life cycle analysis; and environmental impact. These keywords show the interrelationships of the social life cycle assessment with the economic dynamics and sustainability. Some of the relevant countries are the following: Germany; Italy; the USA; Spain; Brazil; France; Netherlands; China; Canada; and Hong Kong. The relevant sources are namely the International Journal of Life Cycle Assessment and the Journal of Cleaner Production. The systematic literature review suggests a better definition of indicators for the social life cycle assessment, more research to support the development of these tools,

the sustainability of more than a sum of indices, and the UNEP/SETAC Guidelines have been taken into account for the assessments based on this life cycle tool. In terms of practical implications, the social life cycle assessment is under development, and more research is needed to support more standardisation and overcome some of the restrictions identified. For policy recommendations, it is suggested to promote scientific contributions based on the already designed UNEP/SETAC Guidelines. For future research, it could be important to understand the interlinkages between economic growth, sustainability and digital transition.

Machine and Deep Learning: Their Roles in the Context of the Economic Growth Processes and Sustainability Assessment
Abstract Sustainability assessments are crucial for more balanced economic growth, and in these contexts, the new technologies, namely those associated with the digital transition, play a fundamental role. Indeed, the technologies related to the Era 4.0 are a hope for governments and international organisations, for example, to deal with the need of promoting economic growth and, at the same time, reduce the carbon footprint. Nonetheless, these digital approaches require expertise and, sometimes, the stakeholders are not prepared to use these new methodologies, or the infrastructures available are not adjusted to the new requirements. In this framework, this study proposes to analyse the contributions of machine and deep learning for economic growth and sustainability assessments. For that, bibliometric analysis and systematic review were carried out, considering documents related to topics associated with the issues here addressed. The insights obtained highlight the potentialities of the machine and deep learning methodologies for sustainability assessments and economic growth. Keywords Agriculture 4.0 · Life cycle cost analysis · Bibliometric analysis · Literature insights
9.1 Introduction The new technologies from the Era 4.0 may bring interesting contributions to the interlinkages between sustainability and economic growth, specifically improving the efficiency in the use of resources, with added value for economic profitability and carbon footprint mitigation [1]. Of course, there are also weaknesses and threats related to the digital technologies implementation, particularly those associated with the availability of infrastructures and the needed skills of the stakeholders. In any case, there is a way to run with interesting perspectives. Machine learning technologies appear, in some cases, as support for methodologies of assessment of the economic growth performance and the respective variables

that may influence the associated dynamics [2]. These approaches are also considered for predictive analysis. These machine learning methodologies were taken into account, for example, to assess relationships among renewable energies and environmental pollution indicators, for the BRICS, G7 and European Union (EU) countries [3]. Another application of the machine learning tools was in the literature review about the circular economy, green economy and bioeconomy [4]. These digital technologies have been taken into account in the following subjects: causes of environmental sustainability [5]; smart cities (may contribute to make compatible economic growth, adjusted transports, sustainability and adjusted planning for the cities) [6]; energy use, economic performance and environmental impacts [7]; relations among human capital and green growth [8]; impacts of industry 4.0 on environmental, social and governance investment in the energy sector [9]; forecasting the acceptance of reopening a nuclear power plant [10]; precision agriculture [11]; hybrid desalination [12]; and interlinkages among total natural resources, economic growth, human capital and cities changes with carbon footprint [13]. Artificial intelligence opens, indeed, new perspectives for the economic sectors’ performance, with relevant potentialities to improve the transparency in the chains, traceability and sustainability, including in the autonomous vehicles supply circuits [14]. These technologies may support analysis with multi-sector and multi-actor to identify efficient policy designs [15]. Considering these frameworks, this chapter aims to bring more insights into the machine learning contributions to the relationships among economic growth and sustainability, considering bibliometric analysis and literature survey based on the metrics from bibliographic data, considering the PRISMA approach [16]. The documents taken into account were obtained from Scopus [17] database, on a search carried out on 17 May 2023. From this search, 38 documents were identified for the following topics: “economic growth”; and “sustainability”; and “machine learning”. To identify the top items, the total link strength metric was considered [18], and for the bibliometric assessment, the procedures proposed by the VOSviewer software were followed [19–21].
9.2 Keywords, Countries, Organisations, Cited Authors, Documents and Cited Sources as Items Figure 9.1 presents the number of occurrences (dimension of the circles and labels) for the keywords identified and the relatedness (proximity) among the items. Table 9.1 exhibits the total link strength, number of occurrences, average publication year and average citations. The keywords with the highest total link strength are closely related to the topics analysed: economic growth; sustainability; and machine learning. The countries with the greatest total link strength are the following (Table 9.2): UK; China; France; Saudi Arabia; Australia; Tunisia; Pakistan; Ecuador; Taiwan; and Italy. Some of these countries have also a relevant number of documents and

citations. The average publication year for the documents published by the authors affiliated with these countries ranges among 2021 and 2022. Figure 9.2 highlights the number of documents (dimensions of the circles and labels) for each item and the respective relatedness. The top 10 organisations for the highest total link strength presented in Table 9.3 are from Italy, Romania, Saudi Arabia and Tunisia. Figure 9.3 shows the number of documents for each organisation and the relatedness (proximity). Some of these top 10 organisations have also an important number of citations. Figure 9.4 and Table 9.4 exhibit the main metrics for the cited authors and cocitation links for the topics: “economic growth”; and “sustainability”; and “machine learning”. The relatedness of the co-citation links is associated with the number of times the items (authors in this case) are cited together. For the bibliographic coupling links, the relatedness is related to the number of references the respective items share, and for the co-occurrence links, the relatedness is based on the number of documents where the items appear together. Table 9.5 presents the top 10 documents.

9.4 Discussion and Conclusions This research intends to assess the contributions of machine learning to sustainability and economic growth, considering insights from the literature. To achieve these objectives, a bibliometric analysis was carried out that was considered to support an oriented literature survey. For that, a search was performed on 17 May 2023 in the Scopus database for the topics: “economic growth”; and “sustainability”; and “machine learning”. For the bibliometric assessment, the VOSviewer procedures were followed, and the following items were taken into account for different links: all keywords; countries; organisations; cited authors; documents; and cited sources. The digital transition may contribute to improve the efficiency in the use of scarce resources, such as water, energy and soil, bringing interesting contributions to the relationships between economic growth and sustainability. This is important, because may mitigate the environmental impacts and increase the income of the economic operators in the different sectors. The lack of digital skills among the stakeholders and the absence of adjusted infrastructures are serious constraints that limit the implementation of the new technologies in some circumstances. In any case, these digital approaches are used as predictive methodologies and to promote sustainability in the supply chains. Considering co-occurrence links, the bibliometric analysis highlights as relevant (with the biggest values for the total link strength) keywords related to the topics here addressed (economic growth, sustainability and machine learning). UK, China, France, Saudi Arabia, Australia, Tunisia, Pakistan, Ecuador, Taiwan and Italy are the countries with greater relatedness. The most relevant cited sources are the following: J. Clean. Prod.; Sustainability; Comput. Electron. Agricult.; Bioresour. Technol.; Sci. Total Environ.; Water Res.; Energy; Renew. Sustain. Energy Rev.; Renew. Energy; and Sensors. It seems that sources focused on the specific dimensions of sustainability are missing here, as well as more sources associated with artificial intelligence. The literature survey based on the bibliometric assessment shows the importance of the digital transition for economic growth and sustainability. On the other hand, this oriented review of the literature reveals that machine learning techniques, for instance, have been taken into account for assessments in diverse contexts of society and science, since municipal waste management, until globalisation and sustainable development. In terms of practical implications, the findings obtained with this research highlight the importance of the new technologies for economic growth more sustainable. On the other hand, it could be relevant to promote the use of these methodologies in other fields of society and science. This narrow perspective of the use of machine learning in the analyses of the interrelationships between economic growth and sustainability is visible in the focus of the most relevant cited sources identified. For future research, it is suggested to analyse the interlinkages among economic growth, assessments and artificial intelligence.

Economic Growth, Sustainability Assessment and Artificial Intelligence: Combinations Among These Three Dimensions
Abstract Sustainability assessment, economic growth and artificial intelligence are related and these interrelationships will be narrower. The question here is how to combine these three dimensions to create a new approach that may be called as “Triple Eco-Digital Assessment”, which promotes more inclusive analysis, and considers the different dimensions associated with sustainability evaluation methodologies, artificial intelligence technologies and economic growth dynamics. In these frameworks, this chapter brings highlights about the several interrelationships between sustainability assessment, economic growth and new technologies and how these linkages may be combined. To achieve these objectives, the top items from the scientific literature were considered (taking into account bibliographic data and co-occurrence, bibliographic coupling and co-citation links). Additionally, the artificial intelligence approaches were considered for an assessment carried out to predict the costs of the farms from the European Union agricultural regions. The main highlights identified bring relevant insights for a more interlinked framework among economic growth, sustainability dynamics and the contexts of artificial intelligence. Keywords Digital transition · Life cycle cost analysis · Sustainable development · Bibliographic data
10.1 Introduction The different economic sectors are faced with diverse challenges in the current contexts worldwide, where the prediction of some costs may be relevant for the planning and production units’ management. This is true for the agricultural sector [1] and for other economic activities. The digital transition and the respective methodologies play a fundamental role in these costs prediction, particularly those associated with the artificial neural network methods [2]. Nonetheless, artificial intelligence also opens new concerns, including ethics and related to human rights, data management and privacy, at the social level and for the workers in the workplace [3]. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023 V.

10 Economic Growth, Sustainability Assessment and Artificial …
In any case, artificial intelligence has been referred to in studies related to the following domains: economic perspectives of coal-source-focused cities in conditions of low carbon strategies [4]; digital transition in the urban facilities and services [5]; urban development in contexts of cities expansion and transformation [6]; water resource planning and management [7]; consequences of social media on geopolitics and economic growth worldwide [8]; in assessment associated with the index of sustainable economic welfare in the Chinese framework [9]; automated examinations of tunnels [10]; forecasting carbon emissions and footprint [11]; river quality analysis [12]; and industry 4.0 and how the companies are involved in these new realities [13]. The interrelationships between artificial intelligence, economic growth and life cycle analysis were considered by Naveenkumar et al. [14] for the management of municipal solid waste; however, it seems that there is here a long way to run, particularly to highlight the potentialities of these interlinkages for the a more sustainable development. These gaps in the literature justify more research about the interactions among economic growth, sustainability assessment and artificial intelligence technologies and suggest that can be proposed a new approach which represents these interrelationships. This approach may be called as “Triple Eco-Digital Assessment” and may be more one contribution to alert the stakeholders to the need of putting together economic growth, sustainability and smart technologies. This may contribute to improvements in the efficiency of the processes and negative environmental impact mitigations. For that, a bibliometric analysis was considered [15, 16], as well as a focused review [17]. On a search carried out on 17 May 2023 on the Scopus [18] database, 69 documents were found for the following topics: “economic growth”; and “assess*”; and “artificial intelligence”. The top items were identified [19], and the procedures proposed by the VOSviewer [20–22] software were followed. An application of the artificial intelligence methodologies was presented at the end of this study for the European Union framework.
10.2 Metrics from the Scopus Database For the topics “economic growth”; and “assess*”; and “artificial intelligence”, Fig. 10.1 and Table 10.1 show that the assessment is important for sustainable development and decision-making. However, between the top 10 keywords (with the biggest total link strength), concepts related to the life cycle sustainability assessment are missing. These top 10 keywords have also a relevant number of occurrences and average citations. The average publication year ranges between 2017 and 2022. The USA, India, China, South Korea, Norway, United Arab Emirates, Lebanon, Australia, Portugal and Denmark are the top 10 countries with the highest total link strength and among these countries are those with an important number of documents and citations (Fig. 10.2 and Table 10.2).

10.3 Predict European Farming Costs with Machine Learning Approaches In this section, considering data from the Farm Accountancy Data Network (FADN) [25] for 2020 and following the IBM SPSS Modeler [26] software procedures for machine learning methodologies will be identified the models with better accuracy to predict farming costs (total inputs costs) in the European Union regions. As predictors, the other variables presented in this database were taken into account. In the FADN database for each region, statistical information for a representative farm is presented. The models with better accuracy (lower relative error) are those associated with the linear regressions, chi-squared automatic interaction detection (CHAID) and random forest, for example. The worse performances were found for the decision trees (Tree-AS) and support vector machine (SVM) (Table 10.7). On the other hand, the most important predictive variables are, respectively, the following (Table 10.8): farm net value added; total intermediate consumption; total labour input; depreciation; yield of wheat; cows’ milk & milk products; fertilisers; total liabilities; and subsidies on external factors. These findings show the importance of the competitiveness of the farms for the level of input costs, as well as the level of use of some inputs, such as fertilisers and labour. These contexts are also influenced by subsidies.

10.4 Discussion and Conclusions This research aimed to highlight the interrelationships between economic growth, sustainability assessment and artificial intelligence and show how these three dimensions may be combined. For that, 69 documents were assessed through bibliometric analysis. These documents were found on a search carried out on 17 May 2023 in the Scopus database for the topics: “economic growth”; and “assess*”; and “artificial intelligence”. For this bibliometric assessment, the procedures proposed by the VOSviewer software were followed. To highlight the importance of artificial intelligence for assessments related to sustainability and economic dimensions, some

results were presented for the prediction of costs in the European Union farms (data from the FADN were considered for 2020). The artificial intelligence approaches may support the stakeholders in the different tasks related to the management and planning of the production units belonging to the diverse economic costs, including the prediction of costs in the agricultural sector. In any case, the implementation of artificial intelligence brings new challenges, specifically those associated with ethical dimensions and human rights. The literature survey highlights that the interlinkages among economic growth, sustainability assessment and artificial intelligence have not been explored enough by the scientific community. The metrics from the bibliographic data reveal that the most relevant keywords (considering the approaches here used) are the following: artificial intelligence; economics; economic growths; risk assessment; sustainable development; decision making; economic analysis; and decision support systems. Some important keywords for the topics here addressed are missing, particularly those related to the sustainability assessment. The most important countries of affiliation are the following: USA; India; China; South Korea; Norway; United Arab Emirates; Lebanon; Australia; Portugal; and Denmark. In the cited sources, again, it seems that the sustainability assessment dimensions may be deeper explored in future research. In the prediction of the total input costs for the farms of the European Union regions, the results show that the linear regressions, CHAID and random forest models are those with better accuracy. In turn, the most important predictors are the farm net value added, total intermediate consumption, total labour input, depreciation, yield of wheat, cows’ milk & milk products, fertilisers, total liabilities and subsidies on external factors. In terms of practical implications, it is suggested to create an approach, which may be designated as “Triple Eco-Digital Assessment”, to promote more research about the interlinkages among economic growth, sustainability assessment (with life cycle tools, for example) and artificial intelligence. For policy recommendation, it could be important to rethink the agricultural subsidies in the European Union based on studies related to the impacts of the respective instruments on the costs of the farms, on the farming competitiveness and the use of some resources (such as the fertilisers and the labour).
