Public Expenditure and Economic Growth in Nigeria: Evidence From Auto-Regressive Distributed Lag Specification

This paper analyses the impact of public expenditure on economic growth in Nigeria during the period 1970 to 2010 making use of annual time series data. The study employs the bounds testing (ARDL) approach to examine the long run and short run relationships between public expenditure and economic growth in Nigeria. The bounds test suggested that the variables of interest put in the framework are bound together in the long-run. The associated equilibrium correction was also signifi cant confi rming the existence of long-run relationships. Our fi ndings indicate the impact of total public spending on growth to be negative which is consistent with other past studies. Recurrent expenditure however was found to have little signifi cant positive impact on growth. Therefore, government should increase its spending on infrastructure, social and economic activities
