This study developed a single country computable general equilibrium (CGE) model including a Household disaggregation in order to measure the potential impacts of two scenarios, the first on full liberalization and the second on the potential implementation of Economic partnership agreement (EPA) between European Union and Ecowas. The classical indicators of poverty and inequality were also computed in addition to the equivalent variation measure in order to capture the effects of the implementation of these policies on Senegalese households. The results show that the EPA scenario seems to be more beneficial in term of welfare variation than the full liberalization scenario. However, the urban households seem to benefit more. The analysis of the inequality indicators shows whatever the scenario considered a decrease of the income inequality. However the EPA scenario again seems to be more beneficial. Lastly, concerning the poverty indicators, the two scenarios envisaged did not seem to reduce poverty.
