Growth Threshold

Purpose This study aims to explore the relationship between the growth threshold effect on renewable energy consumption (REC) in the major oil-producing countries in sub-Saharan Africa (SSA) over the period 1990–2018. Design/methodology/approach This article used a dynamic panel threshold regression model introduced by Hansen (1996, 1999 and 2000) threshold (TR) models. The procedure is achieved using 5,000 bootstrapping replications and the grid search to obtain the asymptotic distribution and p-values. For the long-run relationship among our variables, the author followed the process in Pesaran et al. (1999) pooled mean group (PMG) for heterogeneous panels. Furthermore, for the robustness of our empirical results due to the sensitivity of the results to outliers, the author used the approach by Cook (1979) distance measure. The author applied quantile (QR) regression to explore the distribution of dependent variables following Bassett and Koenker (1982) and Koenker and Bassett (1978) approaches. Findings The results from the threshold effect test and threshold regression revealed a significant single threshold effect of growth level on REC. Furthermore, the result from the PMG estimation showed the growth of the variable, energy intensity, consumer prices and CO2 emissions play a significant role in REC in major oil-producing countries in SSA. The growth threshold estimation results indicated one significant threshold value of 1.013% at one period lagged of real growth. The outlier’s sensitivity detention greatly influenced our empirical results. Originality/value The article filled the literature gap by applying a combined measure that is robustness to detect outliers in the data, which none of the studies in the literature addresses hitherto. Further, the article extends the quantile regression to growth – REC literature.

Purpose This study aims to investigate the causal relationship between nutrition and economic growth in sub-Saharan Africa. Design/methodology/approach A dynamic panel causality test based on the Blundell-Bond’s system generalized methods-of-moment was used. To make efficient inference for the estimates, the authors check for the panel unit root and co-integration relationship amongst the variables. Findings The variables were found to be non-stationary at level, stationary after first difference and co-integrated. The results of the causality tests reveal evidence of long and short-run bidirectional causality between nutrition and economic growth, which implies that nutritional improvement is a cause and consequence of economic growth and vice versa. Originality/value This is the first study to consider causality between nutrition and economic growth in the region.

Abstract With the rapid developments and changes in technology in the Fourth Industrial Revolution being witnessed everywhere, this study aimed to investigate the factors that influence access to the internet by households in emerging economies with a direct focus on South Africa one of the countries in Sub-Saharan Africa. Access to broadband facilities by individuals, households and consumers is one of the critical components of the economic growth and prosperity of a country. It is generally believed that the access to broadband technologies by a community or nation helps to increase productivity which assists a lot in fueling economic growth which will have an impact on the levels of poverty. Using the logistic regression, the study found out that race, access to telephone landline, access to a cellular cellphone, access to electricity, owning a house, gender, age of the household head, net household income per month, and household expenditure were the significant variables in influencing the demand for internet access by households in emerging economies. The factors that were more important in the influence on access to the internet were the availability of electricity and access to a cellphone. Therefore, the study concludes that to improve the quality of life of the people, it is imperative that the governments across the world, do invest more in improving access to quality internet, but one of the prerequisites is that households should have a stable electricity supply and they have access to cellphones.

Panel Threshold Regression

AbstractThis paper investigates the threshold effect of environmental degradation on the FDI-poverty nexus in sub-Saharan Africa for the period 1986–2018. The study used panel threshold regression for the empirical analysis. The evidence from threshold regression using different measures of poverty and environmental degradation shows that the poverty reduction effect of FDI is not eroded by environmental degradation. The study found overwhelming evidence that at the higher level of environmental degradation, FDI contributes significantly to poverty reduction except when Household final consumption is used to proxy poverty and FDI produces an insignificant effect on poverty reduction at the higher level of methane emissions and nitrous oxide emission. Based on this finding, any attempts to reduce environmental degradation by reducing the inflow of FDI will worsen poverty rates in the region.
