This paper investigates the oil price - exchange rate nexus for Nigeria during the period 2007-2010 using daily data. The generalised autoregressive conditional heteroscedasticity (GARCH) and exponential GARCH (EGARCH) models are employed to examine the impact of oil price changes on the nominal...
