This paper examines Gross Domestic Product (GDP) and Export (EXP) of Nigeria between 1970 and 2007 using data from Central Bank of Nigeria's Statistical Bulletin of 2008 for cointegration. Applying Autocorrelation Function (ACF), we find that each of the variables (GDP and Export) is non-stationary. Augmented Engle-Granger reveals that the regression of GDP on Export is actually cointegrated and not spurious. An error correction model shows that GDP does not adjust to change in EXP in the same time period. The regression model obtained also shows that the short-run changes in EXP have a positive impact on the short-run changes in GDP. Keywords: Autocorrelation function, Export, Gross Domestic Product, stationarity, trend.
