Determinants of Imports and Exports in Nigeria: Using Seemingly Unrelated Regression (Published)
The study investigated the determinants of imports and exports in Nigeria. Data for the study was drawn from 1981 to 2023 and employed the Seemingly Unrelated Regression, in order to correct the problem of correlation between the error terms in the imports and exports equations. The finding showed that economic growth, population, oil revenue and trade openness exerted statistical impact on the imports. Similarly, the finding of the study showed that inflation rate, interest rate, trade openness, economic growth, population, oil revenue, and foreign exchange reserve have significant impact on the exports. Moreover, the finding showed that economic growth, population and oil revenue exerted different impact on exports and imports during the period under study. Lastly, the findings showed that sudden shock in the imports spill over to the exports in the period under study. The study therefore recommended that there is need to design effective policy that help in mitigating the spill- overs of effect from imports side to exports side.
