This paper examines the macroeconomic effects of exogenous oil price shock in Nigeria. The paper additionally investigates the symmetric effects of oil price shock and the persistence and/or transitory nature of the shock. To achieve these objectives, the Generalised autoregressive conditional heteroskedasticity (GARCH), Component generalised autoregressive conditional heteroskedasticity (CGARCH) and Exponential generalized autoregressive conditional heteroskedasticity (EGARCH) were employed to estimate the various equations. The results showed that oil price volatility has significant positive effect on exchange rate, foreign external reserves, government revenue, and capital importation. The results also revealed symmetric and persistent effect of oil shock in Nigeria. Based on the results, the paper made recommendations for ameliorating and/or insulating Nigeria from the vulnerabilities of oil price shocks.

This paper examines the Impact of inflation on financial sector development in Nigeria using quarterly data from 2002-2017. Financial sector development is proxied using money supply as a share of GDP (M2/GDP).The Auto-Regressive Distributive lag (ARDL) model is employed to carry out the estimation given the weakness of the Engle-Granger residual-based cointegration technique to test the long-run and short-run effects of the impacts of inflation on financial sector development. The results of the estimation reveal that there is a positive and statistically significant relationship between inflation and financial sector development in Nigeria. There is need to test for threshold effects of inflation on financial development in Nigeria.

PurposeThis paper is focused on determining the asymmetric effects of exchange rate on money demand function in Nigeria.Design/methodology/approachIt employs the empirical model of Baumol–Tobin. Baumol (1952), which was founded on the opportunity and transaction cost of holding money. Monetary aggregates, M1, M2 and M3, are used for the real money balances based on the nonlinear Autoregressive Distributed Lag bound testing procedure.FindingsThe results indicate that the positive and negative partial sum of exchange rate changes differ in magnitude and size, supporting the hypothesis of asymmetric effects of exchange rate changes on the demand for money in Nigeria.Originality/valueThis is the first paper to consider the new broad money aggregate (M3).
