Influence of Fiscal Policy on Gross Domestic Investment (GDI) in Nigeria

The study analyzed influence of fiscal policy on gross domestic investments in Nigeria. Specifically, the influence of government revenue, government expenditure and government debt on gross domestic investments was investigated. Data spanning 36 years, from 1981 to 2017, was used for the study's tests and analysis. For the data analysis, unit root test results showed that the data were of mixed integration, hence the autoregressive distributed lag (ARDL) approach to regression analysis was applied. The ARDL bounds test revealed that fiscal policy and domestic investments in Nigeria had long-run relationship. It was also revealed that government revenue had negative and significant influence on gross domestic investments, while government expenditure and government debt both had positive influence on domestic investments with government expenditure been significant. As such, the paper recommended, among other things, that revenue from sources other than tax should be encouraged, through better means of accelerating agricultural productivity to cushion the dwindling revenue from Nigerian oil sector as this would help to accelerate non-tax revenue in the years ahead.
