| Title | Essays on international trade and heterogeneity |
| Summary | This thesis consists of three chapters: two single authored and one co-authored; each chapter investigates a different way in which varying forms of heterogeneity impact the effects of trade. Chapter 1 presents a computable general equilibrium model that investigates the role trade liberalization has on skilled and unskilled wages. The model allows for endogenous skill formation as workers choose to become skilled or remain unskilled in response to new market conditions. I find that there is a substantial difference in how the skill premium changes depending on which sector is liberalized and on initial country conditions. Chapter 2 also builds a computable general equilibrium model, investigating the welfare impact of EU institutions through free trade. I find that cross-sector input-output linkages play an important role in quantifying the gains from trade, which are orders of magnitude larger than what traditional models predict. Chapter 3 is a joint work with Antoine Berthou and Emmanuel Dhyne, looking at the role firm heterogeneity has in estimating the elasticity of trade. The paper contains a theoretical model delivering sharp predictions which are then tested empirically against a novel dataset. We find that there is a substantial difference in elasticity between high and low productivity firms, as well as between sectors. |
