||Abstract In this thesis we study the effect of Free Trade Agreement (FTA) between European Union and South Korea, especially on the Czech Republic. To do so, we use gravity model. We specify three different gravity equations, each with a different set of fixed effects, and apply two estimation methods on them: Fixed Effects and Poisson Pseudo Maximum Likelihood. Apart from this, we also use traditional indicators (Herfindahl and RCA indices) to assess the changes in trade. The results of the gravity model estimations suggest that the FTA did not have a significant impact on the bilateral trade. However, trade diversification analysis using the Herfindahl index and comparative advantage analysis using the RCA index both indicate that the bilateral trade between the Czech Republic and South Korea improved with the FTA in place.
