Institutions and the financial development–economic growth nexus in sub-Saharan Africa

Using a sample splitting approach that does not impose an exogenous quadratic term, we examine the effect of financial development on economic growth in sub-Saharan Africa by allowing the link to be mediated by the level of institutions. Our findings reveal a disproportionate growth-enhancing effect of finance, given countries’ distinct level of institutional quality. More specifically, when the International Country Risk Guide-based measure of institutions is used as the threshold variable, below the optimal level of institutional quality, financial development does not significantly promote economic growth. For countries with institutional quality above the threshold, higher finance is associated with growth. However, when institutions are measured by World Governance Indicators proxy, we find a significant effect of financial development, irrespective of whether a country is below or above the threshold. Interestingly, the growth-enhancing effect of finance is greater for low-institution countries relative to high-institution countries. Thus, through its ability to provide some crucial roles, the well-developed financial sector may also perform the function of sound institutions in influencing economic growth.     

Impact of agricultural innovation adoption: a meta‐analysis

The impacts of adopting agricultural innovation and technology are widely examined. This paper synthesises 154 studies, which yielded a total of 600 estimates of the impact of adopting agricultural innovation and technology on production, social and economic outcomes. Using meta‐regression analysis, the empirical results show that the reported impact of adopting agricultural innovation and technology rises significantly over time, notwithstanding a significant publication bias. Whether studies find significant impacts of adopting agricultural innovation and technology depends on the use of experimental research designs, parametric method, endogenous switching regression and region. Our results show a large bias in the literature towards agricultural innovations and technologies that focus on high‐yielding varieties and thus, neglect other forms of complementary innovations and technologies.     

Fuzzy Present Value Analysis Model For Evaluating Information System Projects

In this article, the economic evaluation of information system projects using present value is analyzed based on triangular fuzzy numbers. Information system projects usually have numerous uncertainties and several conditions of risk that make their economic evaluation a challenging task. Each year, several information system projects are cancelled before completion as a result of budget overruns at a cost of several billions of dollars to industry. Although engineering economic analysis offers tools and techniques for evaluating risky projects, the tools are not enough to place information system projects on a safe budget/selection track. There is a need for an integrative economic analysis model that will account for the uncertainties in estimating project costs, benefits, and useful lives of uncertain and risky projects. In this study, we propose an approximate method of computing project present value using the concept of fuzzy modeling with special reference to information system projects. This proposed model has the potential of enhancing the project selection process by capturing a better economic picture of the project alternatives. The proposed methodology can also be used for other real-life projects with high degree of uncertainty and risk.     

Technical Note–Design and Analysis of Tent Cash Flow Models for Engineering Economy Lectures

Engineering economy students are typically intimidated by arithmetic gradient series cash flows. Hence, it is beneficial to develop creative ways to make the material interesting and less formidable. This paper presents an innovative method of introducing students to the design and analysis of arithmetic gradient series cash flows in engineering economy courses. Several profiles of arithmetic gradient series cash flows are presented along with techniques of deriving closed form equations for their net present values. A “General Tent Equation” that can be used to solve various arithmetic gradient series cash flows is developed. A numerical example is used to show its implementation and usefulness.     

Feminisation of poverty among the street homeless women in South Africa

This article gives an overview of poverty, deprivation and homelessness as a social ill that is eating deep into the society's fabric. It affirms that these concepts are inextricably linked, illustrating this with the case of the street homeless women. Furthermore, it describes the characteristics of street homeless women in Johannesburg inner city and their perception of poverty. It also describes the survival strategies adopted by these women on the streets. The article also illustrates that street homeless women suffer most from unprecedented population growth, high levels of poverty, homelessness, illiteracy and unemployment. They form part of the largest group of the poorly sheltered population. The street homeless women in particular constitute a population at risk, especially when the nature of their homelessness is concealed. The article suggests it might be appropriate to give special attention to the poorest segment of the population, which includes the street homeless women. They must be made to participate fully and equally in policies and strategies to alleviate poverty.     

The Politics of Shareholder Activism in Nigeria

Shareholder activism has become a force for good in the extant corporate governance literature. In this article, we present a case study of Nigeria to show how shareholder activism, as a corporate governance mechanism, can constitute a space for unhealthy politics and turbulent politicking, which is a reflection of the country’s brand of politics. As a result, we point out some translational challenges, and suggest more caution, in the diffusion of corporate governance practices across different institutional environments. We contribute to the literature on corporate governance in Africa, whilst creating an understanding of the political embeddedness of shareholder activism in different institutional contexts—i.e. a step closer to a political theorising of shareholder activism.     

Trade and growth: The Nigerian experience

This paper analyses the impact of trade on Nigeria's economic growth. Using a two-gap model, it estimates the relationships between exports, foreign capital and economic growth. The paper also provides an assessment of the relative influence of Nigeria's two main types of export (agricultural produce and petroleum) on economic growth. The results of the analysis provide empirical support for the hypothesis that trade has been an important engine of growth in Nigeria. The paper recommends, as part of Nigeria's strategy for achieving rapid economic development, the vigorous pursuit of an export promotion policy.
