The corruption in Nigeria is generating concern around the globe and among its citizens. This concern is because corruption has continued undermining the country's socio-economic development. Thus, this study empirically investigates the impact of corruption on economic growth in the Nigerian economy using annual data from 1980 to 2018. The study employed the autoregressive distributed lag (ARDL) model as its estimation technique. In this study, economic growth was proxied by gross domestic product growth rate (GDPGR), while corruption was proxied by the corruption perception index. The result revealed that corruption has a negative and significant impact on economic growth in Nigeria in the long run. This finding implies that corruption has impeded the economic development process in Nigeria within the period of this study. Thus, it was recommended that anti-corruption agencies in Nigeria, such as the Economic and Financial Crime Commission (EFCC) should be strengthened by enacting laws that will empower them to investigate, arrest and prosecute offenders.

This study examined the role of institutions in modifying the impact of renewable energy consumption on industrial performance in West Africa, and how the relationship differ across countries within the sub region based on income classification. The Driscoll-Kraay standard error and the panel-corrected standard error (PCSE) techniques were utilized to estimate the fixed effects and random effects models, respectively. Institutional quality index was computed using the principal component analysis (PCA). The results reported that renewable energy consumption enhances industrial performance in West Africa and in low-income countries (LICs). However, when institutional quality is interacted with renewable energy consumption, there is a dampening impact on industrial performance not only in West Africa but also in lower-middle-income countries (LMICs). This implies that improving the quality of institutions in West Africa would be instrumental to sustaining and deepening the impact of renewable energy consumption on industrial performance.JEL ClassificationC33, L60, Q40.
