| Resumo: | This thesis investigates various aspects of international trade. In the first chapter, I study the effect of exporting on firms productivity. Specifically, I examine the extent to which export shocks are transmitted along the production chain through input-output linkages. I find that when firms expand into foreign markets, the increase in the derived demand for intermediates boosts the productivity of domestic input suppliers. In the second chapter, I focus on the determinants of markups at firm-product level. I find that when firms start to export new products, the effect on markups depends on the product characteristics. While, on average, markup adjustments do not appear to play a role, for more differentiated products I find evidence of an increase in markups. In the third chapter, I study the relation between exports and patent innovation. Results show that export shocks have a positive effect on firms' innovation. Firms invest the extra profits from the export market to finance the sunk costs of innovation. |
