Abstract

This study examined implication of public expenditure on economic growth in Nigeria. The ordinary least square (OLS) technique, unit root test (ADF), regression (LRGDP) anderrorcorrectionmodel (ECM) were adopted in the research analysis. The findings show that there is a positive and significant effect of government spending on education, economic growth in Nigeria. There is a positive and significant effect of government spending on health, economic growth in Nigeria. There is no negative but significant effect of government spending on power, economic growth in Nigeria. There is a negative and insignificant effect of government spending on defense, economic growth in Nigeria. Public expenditure in Nigeria had some mixed results, because at some points it played major key roles for growth but at other times it did not contribute much for economic growth. But, conclusively, public expenditure had tremendous implication on economic growth in Nigeria.Therefore, the study recommended that government should increase its spending on education, also increase its spending on power and be prudent in its spending on defense.
