We analyze how increases in the market size and in the level of international integration interact with the process of selection among firms with heterogeneous productivity levels when they are interconnected by vertical linkages. We show that larger economies do not always exhibit higher...

We use a quantitative model to study the implications of European integration for welfare and migration flows across 1,318 regions. The model suggests that an increase of trade barriers to the level of 1957 reduces welfare by about 1-2 percent on average, depending on the presumed trade...

Using varieties of a rich model that considers sectoral heterogeneity and input-output linkages, this paper shows that the overall welfare gains of a region within a country can be decomposed into domestic versus international welfare gains from trade. Empirical results based on state-level data...
