An inquiry into the impact of external and domestic borrowings is considered timely for Nigeria, given the growing public debt profile amid deteriorating human capital development. Using data from 1990 to 2021, the study estimates the effects of domestic and external debts on Nigeria's human capital development. The study employed the fully modified ordinary least squares and canonical cointegration regression as the main estimation technique and the robustness check, respectively. The study discovered that domestic and external debt, economic growth and debt servicing exert positive and significant influence on human capital development in Nigeria while environmental pollution has an inverse and significant impact on human capital development in Nigeria. Premised on the outcomes, policy suggestions aimed at enhancing human capital development in Nigeria have been put forward. [ABSTRACT FROM AUTHOR]

This study examines the dynamic effects of external debt stocks on real economic growth in Nigeria—incorporating debt services, interest rate, inflation, and capital formation. The study utilizes annual time series from 1981 to 2017 employing the dynamic autoregressive distributed lag (ARDL) cointegration bounds test methodology. Empirical findings indicated that external debt stocks and debt services have a significant effect on real economic growth both in the short and long run. The result of the pairwise conditional Granger causality gives a short run procyclical bidirectional nexus between capital formation and economic growth. Thus, external debt stocks affect real GDP via the channels of accumulated debts, debt services, and macroeconomic variable fluctuations in the long run. Result obtained supports the objective of the Nigerian Debt Management Office in optimally managing the nation's external debt. [ABSTRACT FROM AUTHOR]
