Ecowas Common External Tariff (CET) and Macroeconomic Performance In Nigeria
The authors aim at providing empirical relationship between ECOWAS Common External Tariff and macroeconomic variables in Nigeria. They 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 (CET) explained as low as 0.006% in the variance of domestic output (DO) in the short run period (2ndperiod) and as low as (0.11) in the long run period (15th Period). The authors observed that ECOWAS common external tariff (CET) has a positive but an insignificant effect on macroeconomic performance in Nigeria.
