The contention in the literature is the relative contribution of private and public investment on economic growth and whether the relationship is linear or non-linear. In addition, there is the issue of whether the impact of investment on economic growth changes depending on public and private investment Purpose. The study examines the relationship between investment (public and private) and economic growth in Nigeria over the period 1970-2016. Design/Methodology/Approach. The study employs Markov regime-switching approach developed by Hamilton (1989, 1990). Specifically, a multivariate dynamic Markov-switching model is estimated using maximum likelihood estimation techniques. The study employs annual time-series sourced from Central Bank of Nigeria, Statistical Bulletin and World Bank, World Development Indicator. Findings/Implications. The results show that the relationship between investment and economic growth is non-linear. Also, both public and private investments have a significant positive impact on economic growth. However, private investment contributes more to economic growth than public investment during the period of expansion. The reverse is the case during the period of contraction. The results support the basic neoclassical framework, with emphasis on savings and investment for analyzing long-term growth performance. Also, it is crucial to make a distinction between the impact of investment (public and private) on growth in two stages of growth. Originality. Government needs to be innovative by spending more during period of slump as more public investment will be required to pump prime the economy for increased private investment.

The paper investigates the impact of fiscal policy channels on selected macroeconomic variables in Nigeria over the period of 1970-2018. The study employed the Bayesian approach of the Dynamic Stochastic General Equilibrium Model, after examining the prior and posterior mean values on the models specified. The paper established that channels of transmission from fiscal policy affected the performance of macroeconomic variables in the country that is, the instability on macroeconomic variables performances in Nigeria are highly influenced by the fiscal policy transmission channels. The study concluded that credit to the private sector, exchange rate, government spending and oil revenue were significant variables in Nigeria that need good policy measure for their performances. The paper recommends that there is a need for a sustained reduction in the fiscal policy channels as this helps in achieving sustainable development and improves variables performance. Also, since credit shock is the most active shock through which Fiscal policy channels transmitted to the economy, effort should be made to encourage banks to create more money in the economy to the private sector. And Central Bank of Nigeria should also pursue the government in financing credit availability in the country.

ABSTRACT The kernel of the debate on the relation between government spending and economic growth is whether the former causes the latter or the latter causes the former. In addition, there is the issue of possibility of nonlinearity in the relation between government expenditure and economic growth. Purpose. The purpose of this paper is to examine the relations between government expenditure and economic growth in Nigeria. Design/Methodology/Approach. The nonlinearity and causality in the relation between government expenditure and economic growth are examined using nonlinear autoregressive distributed lag model (NARDL), vector error correction model (VECM) and causality. Findings/Implications. The findings show the existence of cointegration and nonlinear effect on the relation between government expenditure and economic growth in both long- and short-run. The results equally show unidirectional causality that runs from economic growth to government expenditure thus providing support for Wagner's law in Nigeria. Originality. The findings from this study suggest that nonlinearity and asymmetry should be taken into account when examining the nexus between government expenditure and economic growth.
