Abstract

Purpose - This study examined the effect of economic instabilities on poverty and brain drain in Nigeria
between 1990 to 2023. Design/methodology/approach - The study employed a time series econometric approach using ADF and
Phillips-Perron tests for stationarity and the ARDL bounds testing technique to examine the long-run
relationships. The ARDL model is used for estimation, while diagnostic tests ensure model validity. Findings - The results showed that economic instability variables have both positive and negative effects
on poverty and brain drain, depending on the specific variable and model. Inflation, however, consistently exhibits a positive relationship in both models. All variables were found to be statistically
significant. The diagnostic tests confirm that the models are robust, with no evidence of serial correlation, multicollinearity or heteroskedasticity, and that the models are correctly specified. Originality/value – The study contributes by jointly analysing the impact of economic instability on
poverty and brain drain using ARDL, providing policy-relevant insights into their interconnected effects.
