This study queries the oil price-exchange rate linkage in Nigeria deploying data at daily frequency spanning January 2, 2009 to September 28, 2010. Two volatility models – the generalised autoregressive conditional heteroscedasticity (GARCH) and exponential GARCH (EGARCH) – were deployed to...

This paper examines the long-run and short-run impacts of exchange rate and price changes on trade flows in Nigeria using exports and imports functions. The bounds testing (ARDL) approach to cointegration is applied on a quarterly data from 1980Q1 to 2007Q4. The results indicate that in both the...

This paper probed the long-run and short-run dynamics between stock prices and exchange rates in Nigeria using the Johansen and Gregory-Hansen cointegration analyses, causality test and Exponential General Autoregressive Conditional Heteroskedasticity modelling on daily data from January 2,...

An attempt is made in this paper to query the existence or otherwise of a J-Curve in four West African Monetary Zone (WAMZ) countries: namely The Gambia, Ghana, Nigeria and Sierra Leone. We use data from 1980Q1 to 2007Q4 and a bounds testing approach, with an autoregressive distributed lag...
