This thesis examines whether there is an effect of the Mercosur free trade agreement on export and import between member countries. The study uses an extended gravity model framework on a panel data between the years 1975 to 2017 for 34 countries, including the member countries. Two different regressions were run using OLS and country fixed effect. A Linder effect was also added to the regressions to further understand the impact on trade. The results show a significantly positive effect of the FTA on imports. The FTA yielded insignificant and significantly negative result for OLS and FEM respectively on exports.
