Özet:

This study looked at the composition of government expenditure on growth output (GDP) in Nigeria with the current republic (1999-2021).  The government expenditures considered in the study include: government expenditure on education (GEE), government expenditure on health (GEH), government expenditure on Agriculture (GEA), government expenditure on Road & Construction (GER&C), government expenditure on Transportation & communication (GET&C). The objectives of the study include determining the order of integration of the variables considered in the study and examining the short-run and long-run effect of the selected macroeconomic variables on the growth output with the current republic in Nigeria. The study used various tests such as ADF, Jarque-Bera, and co-integration test to determine the order of integration of variables and examine the short-run and long-run effect of the variables on growth output. The study found that government spending on education increased more than all other expenditures from 2000 to 2021, and GEH was greater than GER&C, GEA, and GET&C from 2010 to 2021. The study concluded that government expenditure has an insignificant short-run and long-run impact on growth output with the current republic in Nigeria, and recommended reversing budgetary allocations to the sectors to have an impact on the economy's overall production.
