Abstract: Analysis of public expenditure constitutes a central issue in public sector economics and public finance literature. Understanding the reasons for government spending growth has been a central concern of public sector economists. This is due to the fact that most economies of the world have consistently had increased government expenditures. Nigeria is not an exception. There is need to ascertain the determinants of size of government expenditure in Nigeria. Short-Run Error Correction Model and long-run static equation were used for comparing the influence of those variables on the size of government spending. The long-run static equation served as a test to compare short-run dynamics with the long-run relationships. Ordinary least squares (OLS estimation technique was used. The stationarity tests showed that none of the variables was stationary at level form, but only after their first difference. The results of this study show that the size of revenue and growth rate of national income (output) and private investment significantly influence the size of public expenditure both in the short run and long run. External and domestic debts significantly influence the size of government expenditure only in the short run. It is recommended that the revenue base should be expanded; conducive environment should be created for private investment to thrive, and debt accumulation should be reduced and used for stabilization only in the short run. The conclusion to draw from this study is that revenue, private investment, and income boost public spending while public debts might be counterproductive.
