The paper observes that rising government expenditure has not translated to meaningful development as Nigeria still ranks amongworld’s poorest countries. In an attempt to investigate the effect of government expenditure on economic growth, we employed adisaggregated analysis. The results reveal that government total capital expenditure (TCAP), total recurrent expenditures (TREC), andgovernment expenditure on education (EDU) have negative effect on economic growth. On the contrary, rising governmentexpenditure on transport and communication (TRACO), and health (HEA) results to an increase in economic growth. The authors’recommendations include among others the following. Government should increase both capital expenditure and recurrentexpenditure, including expenditures on education, as well as ensuring that funds meant for the development of these sectors areproperly managed. Secondly, government should increase its investment in the development of transport and communication, inorder to create an enabling environment for business to strive. Thirdly, government should raise its expenditure in the developmentof the health sector since it would enhance labour productivity and economic growth. Lastly, government should encourage andincrease the funding of anti-corruption agencies in order to tackle the high level of corruption found in public office.
