This paper introduces quality innovations with endogenous sunk costs in a heterogeneous firm model of international trade and derives implications for the gravity equation. The model predicts that the effect of fixed costs on exports and on the share of exporters is lower in industries with a...

We investigate the effect of better access to foreign markets on innovation strategies of multi-product firms in industries with different scope for product differentiation. Industry-specific demand and cost linkages induce a distinction between the returns to innovation. In differentiated...

This paper provides first firm-level evidence of the links between income inequality and the patterns of trade and export prices. We identify a theoretical mechanism behind these links, which suggests that a more unequal income distribution leads to higher average prices. We test the theory...

This paper uncovers new stylized facts on the relation between economic integration and world trade prices. Using export price data combined with data on 32 WTO (World Trade Organization) accessions by developing countries and hundreds of new PTAs (Preferential Trade Agreements), we show that a...
