Exchange Rate Volatility on Investment and Growth in Nigeria, An Empirical Analysis
This paper examines the effect of exchange rate volatility on investment and growth in Nigeria over the period of 1986 to 2014. The vector error correction method, impulse responses function, co-integration and Augmented Dickey Fuller (ADF) test for stationarity were employed to capture the interactions between the variables. The results confirm the existence of long run relationship between exchange rate, investment, interest rate, inflation and growth. Finally the results show that exchange rate volatility has a negative effect with investment and growth while exchange rate volatility has a positive relationship with inflation and interest rate in Nigeria. Based on our findings, we recommended that the policy makers should developed sound exchange rate management system in the country potent enough for better growth in the economy.
Oil Revenue, Government Expenditure and Poverty Rate in Nigeria
This study examines the impact of revenue from oil proceeds and disaggregated government spending on poverty rate in Nigeria. Different econometrics tests i.e. pre-estimation test, estimation techniques and diagnostic tests such as Augmented Dickey Fuller, Engel- Granger co-integration, Ordinary Least squares and Granger causality were analysed using the data sets within the period of 1970 and 2013. Empirical result disclosed that gross domestic product and revenue from oil proceeds exert negative effect on poverty rate in Nigeria during the reviewed period. This revealed that oil proceeds being the main revenue source in Nigeria have greater impact in ensuring equal distribution of income as a means of reducing poverty level among her citizens. Painstakingly, these proceeds are not channelled into right directions with regards to government spending on capital projects and recurrent expenditure. This further exacerbates the poverty level in Nigeria.
