This study aims at providing empirical relationship between ECOWAS Common External Tariff and macroeconomic variables in Nigeria. The study made use of quarterly time series data between 2005:01 to 2012:04. The vector error correction model (VECM) model was used to measure the impact of CET on macroeconomic variables in Nigeria. The results revealed that common external tariff (ET) explained (0.006%) in the variance of domestic output (DO) in the 2nd period and rose sharply to (0.02%) in the 4th period. The effect of common external tariff (ET) on the explained variance of domestic output (DO) declined from (0.07%) to (0.08%) at both 6th and 7thperiod respectively. However, common external tariff effect (ET) on the variance of domestic output (DO) decline to (0.08%) at the 8th periods and stabilized at (0.11%) until the 15th period. The study observed that ECOWAS common external tariff (ET) have a positive but minimal effect on macroeconomic performance in Nigeria.
