The impact of government spending on Nigeria’s inflation levels between 1999 and 2019 was x-rayed in this paper. The data for the study were sourced from CBN statistical bulletin and Autoregressive Distributed Lag model was used as the main analytical tool.

A long-run relationship among this study’s variables was realized, using the ARDL Bounds test. The result also revealed a positive but insignificant relationship between government expenditure and inflation rate in the short-run. Moreover, in the long-run, government expenditure has negative and is statistically significant inflation rate. Money supply has a negative and is statistically insignificant with inflation rate in the short-run. In the long-run, money supply has a positive and significant relationship with inflation rate. Gross domestic product was negatively related to inflation rate in both short-run and long-run. Moreover, exchange rate affected inflation rate negatively and significantly in the short-run and positively and significantly in the long-run. The increasing demands of the population affected inflation rate positively and significantly in both short-run and long-run. Investment was positively related to inflation rate but not significant in the short-run but the relationship was negative and significant in the long-run. The study therefore recommended among others that government should exercise discretion in spending in order to check inflation rate. This can be done by channeling spending on productive activities that will cushion the effect of inflation rate rather than exacerbate it.
