Abstract:
The study investigated the effect of the joint interaction between oil revenue and governance on life expectancy in Nigeria 1990-2021. The study adopted the Autoregressive Distributive Lag (ARDL) modelling techniques for the data analysis. Data for the analysis were sourced from secondary sources such as World Data Index (WDI) and CBN Statistical Bulletin. The results of the analysis indicated as follows; the ARDL ECM regression results showed that in short run, the coefficients; ORV*GOE has a positive (0.000507) relationship with LER, ORV*ROQ has a negative (-0.000158) relationship with LER, ORV*VOA has a negative (-0.000092) relationship with LER, ORV*COC has a positive (0.000026) relationship with LER, ORV*ROL has a positive (0.000675) relationship with RPI. The Breusch-Godfrey Serial Correlation LM Test result showed that there is no serial correlation in the model. The Breusch-Pagan-Godfrey Heteroskedasticity Test result suggests that there is no evidence of heteroskedasticity in the model. The study concluded that oil revenue and governance has not promoted economic development in Nigeria within the period under review and recommended that there should be accountability and transparency on the part of government and officials in the management of oil revenues for the benefit of the citizens and the economy as a whole.
