The purpose of this paper is twofold: to investigate the existence of different degrees of returns to scale in low-tech and high-tech manufacturing industries; and to examine whether the degrees of returns to scale change through time.

The empirical investigation implemented in the paper uses data from the EU KLEMS Database, covering a sample of 12 manufacturing industries in 11 OECD countries over the period 1976-2006. The investigation employed two different estimation methods: instrumental variables and system GMM. The robustness of the results was assessed by employing two different specifications of Kaldor-Verdoorn’s Law, by using lags and five-year averages to smooth business-cycle fluctuations, and by dividing the sample into two time periods.

The results reported in the paper provide strong evidence in support of the hypothesis of substantial increasing returns to scale in manufacturing. The investigation suggests that high-tech manufacturing industries exhibit larger degrees of returns to scale than low-tech manufacturing industries. Finally, the analysis revealed also that the magnitude of the returns to scale in manufacturing have increased in the last decades, driven by increases in the magnitude of returns to scale observed in high-tech industries.

No previous work has assessed the hypothesis that increasing returns to scale vary according to the technological content of industries. Moreover, no previous work has used system GMM or data from EU KLEMS to test Kaldor-Verdoorn’s Law. Most importantly, the findings of the paper present new evidence on the degree of returns to scale in high-tech and low-tech manufacturing industries.

This article aims to evaluate the entry and exit of companies from local productive structures, with a specific focus on the sectoral complexity of these activities and the complexity of these portfolios. The study focuses on empirically demonstrating the thesis that related economic diversification exacerbates the development gap between more and less complex regions.

The article uses indicators formulated by the economic complexity approach. They allow a relevant descriptive analysis of the economic diversification process in Brazilian micro-regions and provide the foundation for the econometric tests conducted. Through three distinct estimation strategies (OLS, logit, probit), the influence of complexity and relatedness on the entry and exit events of firms from local portfolios is tested.

In all estimated models, the stronger relationship between an activity and a portfolio significantly increases its probability of entering the productive structure and, at the same time, acts as a significant factor in preventing its exit. Furthermore, the results reveal that the complexity of a sector reduces the probability of its specialization in less complex regions while increasing it in more complex regions. On the other hand, sectoral complexity significantly increases the probability of a sector leaving less complex local structures but has no significant effect in highly complex regions.

Due to the data used, the indicators are calculated considering only formal job numbers. Additionally, the tests do not detect the influence of spatial issues. These limitations should be addressed by future research.

The article characterizes a prevailing process of uneven development among Brazilian regions and brings relevant implications, primarily for policymakers. Specifically, for less complex regions, policies should focus on creating opportunities to improve their diversification capabilities in complex sectors that are not too distant from their portfolios.

The article makes an original contribution by proposing an evaluation of regional diversification in Brazil with a focus on complexity, introducing a more detailed differentiation of regions based on their complexity levels and examining the impact of sectoral complexity on diversification patterns within each group.

This article suggests that given the fulfilment of a number of preconditions Public–Private Partnerships (PPPs) may be attractive instruments for countries in Africa seeking to improve the quality and competitiveness of their services base, particularly the so-called infrastructure services. This article builds, in addition to a selective review of the vast literature on PPPs, on first-hand practical experience on the ground and a number of pilot projects. This methodological approach provides a non-exhaustive PPP mapping in Africa, which in turn leads to a discussion of some of the challenges and risks to PPPs in Africa. It also covers a discussion of the recent trends in the approach to improving the enabling environment upon which are based a few policy recommendations, respectively: establishing an institutional framework for PPPs; designing a realistic and efficient strategy for enabling environment improvement; and finally moving from national-level initiatives to intergovernmental initiatives. This article takes the position that a series of pitfalls and shortcomings, many of which are associated with the enabling institutional environment and the governance framework, need to be addressed if PPPs are to deliver their full potential in Africa. It is believed that the national and intergovernmental PPP initiatives could lend significant support to achieving the 2030 Agenda for Sustainable Development in Africa. In addition to the reviewing and discussing primarily the most recent literature on PPPs, the main value addition of our chapter brings to the literature is derived from the presentation of recent PPP cases, which draw directly from the authors own practical experience on the ground.

Adopting the research concept of socioemotional wealth (SEW) as applied to family firm leaders, this study aims to analyse the literature on succession and corporate governance processes in family firms in keeping with this still developing concept and thereby not only contributing to advancing knowledge on this field but also proposing a conceptual model of analysis and a future research agenda.

The authors carried out a review and systematisation of the literature according to its different thematic groups through recourse to VOSviewer software and content analysis to establish a systematised and integrated structure of the reference literature based on a sample of 218 studies published and indexed on the Web of Science and SCOPUS databases between 2010 and 2021.

The results portray five leading clusters, specifically, (1) SEW and family firm performance; (2) SEW and the focus on leadership as a precursor to succession; (3) family firms, SEW and corporate social governance; (4) family firm innovation and performance; and (5) family ownership and management. The authors then put forward a conceptual model of analysis both to better integrate these topics and as a proposition for application in future research projects.

The study provides a new and solid systematisation of the literature and supports the argument that family firms concentrating on developing the leader's SEW increase the probability of structuring a successful succession process as well as the likelihood of achieving higher quality corporate governance.

The purpose of this paper is to involve the differences in the entrepreneurial intentions of student at higher education institutions (HEIs) in the Portuguese regions (mainland and insular).

Applying a sample of 594 valid responses, the authors analyzed the data according to linear regression models.

The results convey how HEI students generally do not intend to become entrepreneurs in both the mainland and the insular regions. Although HEI students broadly do not aim to launch their own businesses, the results show that students in mainland regions feel they have the skills to start a business and drive it to success. In insular regions, students feel encouraged by their friends and family to set up their own business. When comparing insular and mainland regions, the results demonstrate how in insular regions, there is a greater probability that HEI students become entrepreneurs than in the mainland regions. Furthermore, entrepreneurial intentions in the mainland regions develop in terms of “opportunities” while driven by necessity in the insular regions.

This furthermore makes recommendations to regional governments and to HEIs in order to enable better encouragement of entrepreneurship in academia.

This study is original and innovative due to its comparison of the entrepreneurial intentions prevailing in mainland and insular regions and may propose new highlights to the academic scientific literature.

The increasing competition among higher education institutions (HEI) has led students to conduct a more in-depth analysis to choose where to study abroad. Since students are usually unable to visit each HEIs before making their decision, they are strongly influenced by what is written by former international students (IS) on the internet. HEIs also benefit from such information online. The purpose of this paper is to provide an understanding of the drivers of HEIs success online.

Due to the increasing amount of information published online, HEIs have to use automatic techniques to search for patterns instead of analysing such information manually. The present paper uses text mining (TM) and sentiment analysis (SA) to study online reviews of IS about their HEIs. The paper studied 1938 reviews from 65 different business schools with Association to Advance Collegiate Schools of Business accreditation.

Results show that HEIs may become more attractive online if they financially support students cost of living, provide courses in English, and promote an international environment.

Despite the use of a major platform with a broad number of reviews from students around the world, other sources focussed on other types of HEIs may have been used to reinforce the findings in the current paper.

The study pioneers the use of TM and SA to highlight topics and sentiments mentioned in online reviews by students attending HEIs, clarifying how such opinions are correlated with satisfaction. Using such information, HEIs’ managers may focus their efforts on promoting international attractiveness of their institutions.

The relevance of entrepreneurship in the economic systems of the regions is well documented. Recently, a new concept has emerged in the entrepreneurship literature, entrepreneurial ecosystem (EE), to analyze the dynamics of a given territory and its outputs and impact upon entrepreneurship. Moreover, it is also well documented the close relationship between entrepreneurship and family business (FB). Keeping in mind the multidimensionality of the latter, its scholars are beginning to look into the entrepreneurial elements embedded in the family processes and the influence of context.

After an extensive literature review made, a significant gap was found, given the historical relevance that FB (SMEs the vast majority) have in the global economic systems. A FB entrepreneurial ecosystem (FBEE) model is proposed based on the data collected from two case studies, on Portugal's wine industry, and Mexico's shoe industry, both artisan industries confronted with the urge to reinvent and adapt to face deep market and industry changes.

The results should indicate the feasibility of proposing a second level on the theory of EE, the FBEE, where both the family and business itself ultimately play a vital role in its success and impact the whole system.

This study aims to analyse the relationship between health human capital and economic growth for a maximum sample of 92 countries over the period 1980-2010 taking into account countries’ heterogeneity by assessing how health variables affect different countries according to their position on the conditional growth distribution.

The paper estimates a growth regression applying the methodology proposed by Canay (2011) for regression by quantiles (Koenker, 1978, 2004, 2012a, 2012b) in a panel framework. Quantile regression analysis allows us to identify the growth determinants that present a non-linear relationship with growth and determine the policy implications specifically for underperforming versus over achieving countries in terms of output growth.

The authors’ findings indicate that better health is positively and robustly related to growth at all quantiles, but the quantitative importance of the respective coefficients differs across quantiles, in some cases, with the sign of the relationship greater for countries that recorded lower growth rates. These results apply to both positive (life expectancy) and negative (infant mortality rate, undernourishment) health status indicators.

Given the predominantly public nature of health funding, cuts in health expenditure should be carefully balanced even in times of public finances sustainability problems, particularly when growth slowdowns, as a decrease in the stock of health human capital could be particularly harmful for growth in under achievers. Additionally, the most effective interventions seem to be those affecting early childhood development that should receive from policymakers the necessary attention and resources.

This study contributes to the existing literature by answering the question of whether the growth effects of health human capital can differ in sign and/or magnitude depending on a country’s growth performance. The findings may help policymakers to design the most adequate growth promoting policies according to the behaviour of output growth.

The Paris agreement for climate changes brought new attention to the themes of reduce carbon emissions, green ecosystems, the circular economy and the need to ensure the emergence of sustainable entrepreneurial ecosystems. This study aims to investigate entrepreneurship from the perspective of circular economy and waste collection in the Portuguese context.

Following a quantitative approach, the sample comprises 2,690 firm-year observations related to 354 firms from different industries within the waste from electric and electronic equipment (WEEE) scope.

The results show that a large part of SMEs started to comply with waste management regulations as of 2006 and are still not prone to innovation. Regulatory compliance is expected to have a positive impact on innovation, with a significant and positive change in the number of patents and the value of intangibles after companies comply with the waste management regulation.

This paper is original because it addresses equally to entrepreneurial ecosystems and circular economy (studies that address these two aspects are rare), with the Portuguese context in an embryonic stage with an extensive path to follow in the applicability of circular economy to business.

This work aims to develop a web platform for inspecting roof structures for technical assistance supported by drones and artificial intelligence. The tools used were HTML, CSS and JavaScript languages; Firebase software for infrastructure; and Custom Vision for image processing.

This study adopted the design science research approach, and the main stages for the development of the web platform include (1) creation and validation of the roof inspection checklist, (2) validation of the use of Custom Vision as an image recognition tool, and (3) development of the web platform.

The results of automatic recognition showed a percentage of 77.08% accuracy in identifying pathologies in roof images obtained by drones for technical assistance.

This study contributed to developing a drone-integrated roof platform for visual data collection and artificial intelligence for automatic recognition of pathologies, enabling greater efficiency and agility in the collection, processing and analysis of results to guarantee the durability of the building.
