The impact of financial development on economic growth has received considerable attention since the 2008/2009 global financial crisis. High levels of credit to the private sector were partly to blame for the crisis, and this has re-ignited the debate on whether the growth-enhancing effects of financial development outweigh the retarding effects associated with financial crises. This paper therefore examines the financial development–growth nexus in SADC countries during the period 1990–2015.

The empirical analysis is conducted using the pooled mean group estimator. Furthermore, financial development indices are created due to the strong correlations between the individual financial development indicators using principal component analysis.

The results show that financial development, captured by the indices or the individual financial development indicators, has a negative impact on economic growth in the long term.

Due to the unavailability of data, the study only focussed on banking sector development. The researcher would have preferred to incorporate stock market development.

Due to financial vulnerabilities emanating from an inadequate monitoring and supervisory framework, further enhancement of financial development should be undertaken with caution in SADC countries. Therefore, institutional quality should be enhanced in order for SADC countries to benefit from the development of the financial sector.

Most studies investigating the financial development–growth nexus in SADC countries utilise the individual measures of financial development which often produce contradicting results. This study constructs financial development indices to capture the impact of various banking sector development indicators on growth.

This paper examines the effect of both de jure and de facto measures of financial integration on bank profitability in five regional economic communities of Africa.

Using panel data from 405 banks operating in 47 African countries across five regional economic communities over 2007–2014, the study constructs a composite measure of bank profitability. The study then employs the dynamic two-step system GMM estimation technique to test the effect of both de jure and de facto measures of financial integration on bank profitability in Africa and across five sub-regional markets.

Overall, the results support a positive relationship between financial integration and overall bank profitability in Africa, except for the Arab Maghreb Union and Southern Africa Development Community.

The findings of this study suggest that increased financial integration in Africa directly improves bank’s overall profitability and the variations among the sub-regional markets inform tailored policy initiatives.

To the best of the authors' knowledge, this is the first study on Africa to employ a composite measure of bank profitability to assess its determinants. It is also the first to include both de facto and de jure financial integration measures in a single study. This is also the first largest comparative study on bank profitability in Africa.

Considering the inherent relationship between environmental degradation and the process of economic development, the latter is particularly reliant on the accumulation of human capital, which also emerges as one of the fundamental principles underlying green growth. However, this relationship tends to overlook varying levels of human capital. Hence, the purpose of this study is to examine the enduring associations between the stock of high human capital and green economies in terms of environmental sustainability among the key countries in the Asia Pacific region, namely Australia, Japan, Singapore, and South Korea, spanning the period from 1990 to 2022.

This paper employs second-generation techniques. The long-term relationships were estimated using two constantly updated models - fully modified and bias corrected, CUP-FM and CUP-BC, respectively, to guarantee the robustness of our conclusions for the presence of cross-sectional dependency.

There is a long-term relationship between the stock of high human capital and the sustainability of the environment, in the same way that we have also found the same relationship between the development of socioeconomic practices of green economies. Finally, we conclude that, in the same way as the environmental Kuznets curve, the countries in our sample incur less environmental pollution as their level of income increases. This relationship may be motivated by a process of technological substitution and investment in the development of new techniques and technology to improve the efficiency of productivity with respect to the environment.

We suggest that investing in education and promoting green economies can be powerful tools in the fight against climate change and promoting environmental sustainability. By prioritizing investments in renewable energy and sustainable technologies, policymakers can promote long-term economic and environmental health. Moreover, the findings suggest that promoting education in countries with high levels of environmental pollution can develop the knowledge and skills needed to implement sustainable practices and technologies. Ultimately, these efforts can contribute to improving income, productivity, and society's living conditions while reducing the environmental impact.

This research studies for the first time the load capacity curve hypothesis in determining the effects of the stock of high human capital and green economies on the environment. Consequently, limited papers have used the load capacity factor in the study of the relationships that we propose, especially that of human capital, which has scarcely been studied in relation to its contribution to the environmental fight.

The study aims to focus on the effectiveness of international investment agreements (IIAs) in helping or facilitating the influx of foreign direct investment (FDI) to host developing countries.

To critically examine the topic, the black letter approach and the socio-legal analysis are adopted. The study has analysed how Mauritius, being a developing country, is responding to FDI needs from various bilateral and multilateral investment treaties concluded, and the research includes the analysis of official data publicly made available by the World Trade Organization, Organisation for Economic Co-operation and Development, International Monetary Fund and Mauritius governmental agencies’ reports.

From the methodologies used, it was found that other than IIAs, there are various key determinants which foreign investors consider prior to injecting their capital in developing countries in terms of environmental, social and cultural factors. Also, there are some inherent loopholes mostly in terms of monitoring, in the way IIAs are concluded and are applied in practice by and amongst signatory states.

This research is amongst the first studies to conclude the link between IIAs and FDI flows in developing countries with a particular focus on Mauritius. Additionally, an overwhelming number of studies have emphasised on the efforts to boost FDI, which are inspired mostly by action plans of developed nations, but this research will analyse the policy options adopted by China, being itself a developing country, and the extent to which such recommendations are applicable in the context of Mauritius will also be considered.

The paper aims to investigate the forms of power, politics and leadership exercised by project leaders within asynchronous virtual project environments (VPEs). The purpose of this paper is to link effective project leadership to particular forms of power and politics within a VPE.

The empirical data are based on a quantitative telecommunications sector case study, complemented with some interviews, following a semi‐structured approach. The research was approached based from a positivistic philosophical paradigm and using a survey research strategy. The questionnaire‐based survey consisted of a sample of 28 respondents split between project managers (39.3 percent) and team members (60.7 percent).

The research results indicated a significant finding which linked leadership effectiveness to asynchronous VPE usage and communication. Factor analysis of the type of leadership exercised within an asynchronous VPE revealed two forms of effective leadership. The first one, named, Structured Charismatic Exchange, is underpinned by three forms of leadership styles: charismatic, virtual and transactional leadership. The second insight from the factor analysis also revealed significant loadings for two forms of leadership: Participative and Shared leadership. The common strand in both is the need to elevate the ethos of teams, which effectively implies that control in VPE ought to be decentralized responsibly to enhance sharing. This is possibly relevant in a bid to minimize conflicts and thus develop a project organization that encourages teamwork. Therefore, this factor was named Decentralized Team Leadership. Unlike the first factor, where the focus is on how the project leader projects his/her personality to influence people, the realization is that for a project organization to succeed, project goals and decisions emerge from bargaining, negotiating, and jockeying for position among members of different coalitions.

Reported limitations are based on the sample size, effect of sectoral culture on the findings and constrained view of the virtuality construct. Future research should investigate other sectors with a large sample and expand the dimensions of the virtuality as a construct.

The paper concludes that project leaders should re‐orient leadership practices to fit virtual project environments, taking into account the need for a more decentralized form of leadership and systematic trust building.

The recognition of the uniqueness of particular forms of power and politics relevant for the exercise of effective leadership in asynchronous virtual environments is emphasized in this research paper.

This paper presents the findings of assessing the strategies required for improved work-life balance (WLB) of construction workers in Eswatini. This was done to improve the work-life relationship of construction workers and, in turn, improve the service delivery of the construction industry in the country.

The study adopted a quantitative research approach using a questionnaire administered to construction professionals in the country. The data gathered were analysed using frequency, percentage, Mann–Whitney U test, exploratory and confirmatory factor analysis (CFA).

The findings revealed that the level of implementation of WLB initiatives in the Eswatini construction industry is still low. Following the attaining of several model fitness, the study found that the key strategies needed for effective WLB can be classified into four significant components, namely: (1) leave, (2) health and wellness, (3) work flexibility, and; (4) days off/shared work.

The findings offer valuable benefits to construction participants as the adoption of the identified critical strategies can lead to the fulfilment of WLB of the construction workforce and by extension, the construction industry can benefit from better job performance.

This study is the first to assess the strategies needed for improved WLB of construction workers in Eswatini. Furthermore, the study offers a theoretical platform for future discourse on WLB in Eswatini, a country that has not gained significant attention in past WLB literature.

The purpose of this study is to critically examine the move to Africanise international investment law (IIL) aimed at promoting sustainable development on the continent.

The study analyses the move by African countries to “Africanise” IIL by incorporating specific and innovative provisions and features in their international investment agreements (IIAs) for the benefit of African economies. This is evidenced by provisions in African regional investment instruments such as the 2007 Common Market of Eastern and Southern Africa Investment Agreement and the 2008 Economic Community of West African States Supplementary Act on Investments produced by the different African regional economic communities (RECs), new-generation IIAs such as the 2016 Nigeria-Morocco IIA and the China-Tanzania IIA and the African Union’s Pan-African Investment Code 2016. The common features of these instruments include linking the objective of investment promotion and protection to sustainable development; excluding portfolio investments; including provisions on investor-obligations; and reserving wide scope of regulatory space for host-states, including the ability to take emergency measures without incurring liability to investors. Some of these provisions are rare in IIAs.

The study finds that, while the efforts are commendable, there are real challenges. Firstly, there are inconsistencies in the regimes existing on the continent due to differences in the contents of the international investment instruments promulgated by the different RECs, and also differences in the content of IIAs signed by some member-states of the RECs with countries external to the RECs. Secondly, there are governance gaps and a lack of enforcement in practice, which would undermine the effectiveness of the laws being forged. Thirdly, the Africanised IIL alone would not attract investment if other important determinants, such as critical infrastructure, remain lacking. Fourthly, there is under-representation of Africa in the arbitral institutions that develop and enrich the laws, which, if it continues, would undermine the effectiveness of the Africanisation provisions being included in IIAs.

While the research discusses both law and policy, more is discussed of the law, owing to space limitation.

It is anticipated that this research will impact the content of the investment protocol under the African continental free trade area and beyond and will prompt review of existing and future IIAs by member states of the various RECs to align them for consistency. It is also hoped that this research will impact the review of various investment instruments of the RECs with the aim of harmonising them. It is further hoped that this research would contribute to addressing the challenges that militate against the achievement of the goals of Africanising ILL for sustainable development.

The study is original. It has not been published previously and the authors have found no existing publication that addresses the issues covered in this study.

This study sought to examine the extent to which outsourced contracts, buyer-supplier trust and supplier opportunistic behavior explain supplier performance in Ugandan Public Procuring and Disposing Entities (PDEs). This study was prompted by reports of long lead times, failure to match specifications, late deliveries, poor quality of services delivered, contract violations, and increased supplier cheating. Cross sectional data from 116 central government PDEs concerning outsourced contracts was collected using a self-administered questionnaire. Hierarchical regression was used to indicate what happens to a model that was developed as part of this research as different predictor variables are introduced. The findings revealed that outsourced contracts, buyer-supplier trust, and supplier opportunistic behavior are significant predictors of supplier performance. The study has both managerial and policy implications which are discussed in this paper.

This paper aims to investigate the heterogeneous effects of macroeconomic and financial factors across various distributions of financial deepening in 22 African countries over the past two decades (2000–2019).

The paper uses a recent method of moments quantile regression, which accounts for the often overlooked heterogeneity effects. The analysis focuses on the banking sector, which is predominant in Africa, using a broad range of macroeconomic and financial indicators.

The findings show that gross domestic product per capita positively and significantly impacts financing deepening with an increasing marginal benefit as depth increases. Trade openness positively and substantially affects only high financial deepening. Real interest rate, real exchange rate and inflations negatively and significantly affect financial deepening, especially at higher than lower levels. Financial stability positively and substantially influences financial deepening with an increasing marginal benefit as the depth increases. Bank lending interest rate, bank lending–deposit rate spread, bank concentration and return on equity negatively and substantially impact higher levels of financial deepening than lower levels.

These findings are crucial to policymakers and development partners, as promoting a favourable financial environment and stable macroeconomic policies based on the heterogeneity of financial depths can increase debt financing in Africa.

To the best of the authors’ knowledge, this paper is one of the first attempts to analyse the heterogeneous effects of macroeconomic and financial determinants on varying levels of financial depth in Africa.
