Developing countries in the factor-driven stage of development are usually bedevilled by domestic supply-side constraints which hinder translation of their comparative advantages to development. This study examines the domestic supply-side determinants to intra-Africa export performance in selected African countries. The study analysed 1994 to 2019 panel data of the biggest economies in each of the five African sub-regions, using pooled mean group (PMG) technique. The result from the study revealed capital formation, institutional quality, macroeconomic stability, technology adoption and infrastructure as significant long-run determinants of intra-Africa export performance while size of labour force was found to be insignificant long-run determinant of intra-Africa export share. All short-run coefficients of explanatory variables except one period lag of infrastructure and capital formation were insignificant. The coefficient of error correction term was negative and statistically significant. Based on the findings of this study macroeconomic stability, infrastructural development, pro-market institutions, capital formation and technology adoption are imperative for intra-Africa export performance in the studied countries.

Engagement in informal economic activities serves as a survival strategy for underprivileged majority in developing economies with high level of corruption. Consequently, this study examined the main and interaction effects of informality and corruption on income inequality in Nigeria from 1996 to 2020 using autoregressive distributed lag-bound testing technique. The study result showed evidence of long-run relationship among informality, corruption and income inequality. The main effects of informality and corruption on income inequality are negative and statistically significant in both the short and long run. However, corruption reduction in a year was found to reduce income inequality in the subsequent year. Furthermore, the interaction effect of informality and corruption on income inequality was found to be negative and statistically significance in both the short run and the long run. Corruption reduction was found to be a necessary but not sufficient condition for reduction of inequality. Consequently, this study recommended creation of socioeconomic environment conducive for the growth, expansion and eventual formalization of informal businesses. The study also recommended that inequality-reduction be made the end goal of corruption-reduction by ensuring that the proceeds from successful anticorruption campaign are channelled to policies and public projects which redistribute income to the less privileged.
