Empirical evidence tends to reject the prediction of neoclassical models that fiscal policy cannot affect growth in the long run. However, the results are far from conclusive. This paper aimed at the trend and empirical analysis of public expenditure and its impact on the economic growth in Nigeria. Unit root approach (ADF) was used to investigate the stationarity of the variables. Johansen Co-integration revealed that RGDP, RGPE and RTRF are cointegrated atmost1* with at least 2 cointegrating equations at 5% level. The graphs showed that the growth rates had been unstable over the years and the exogeneous variables decreasingly explained the variation in RGDP by 4%. The VEC result indicated that RGPE established long run relationship with RGDP at 5%. Finally, there is no statistical significance between public expenditure variables and the economic growth in Nigeria. The study recommended that government should embark on realistic policy implementation with sincere fiscal and monetary policies in place that can monitor to greater extend and help in the sustainability for remarkable growth to be recorded in the Nigeria.
