Three sources of gains from trade under monopolistic competition are: (i) new import varieties available to consumers; (ii) enhanced efficiency as more productive firms begin exporting and less productive firms exit; (iii) reduced markups charged by firms due to import competition. The first...

We examine the employment responses to import competition from China and to global export expansion from the United States, both of which have been expanding strongly during the past decades. We find that although Chinese imports reduce jobs, at both the industry level and the local commuting...

This paper develops a two-country macro model with endogenous tradability to study features of international economic integration. Recent episodes of integration in Europe and North America suggest some surprising observations: while quantities of trade have increased significantly, especially...

International economic integration yields large potential welfare effects, even in a static constant returns competitive world economy. Our method is novel. The effect of border barriers on trade flows is often inferred from gravity models. But their rather atheoretic structure precludes welfare...

This paper studies empirically the effects of financial crises on international trade. The major findings are that banking crises had a negative impact on imports but a positive impact on exports in the short term, whereas currency crises decreased imports in the short term and stimulated...

Gravity-based cross-sectional evidence indicates that currency unions stimulate trade; cross-sectional evidence indicates that trade stimulates output. This paper estimates the effect that currency union has, via trade, on output per capita. We use economic and geographic data for over 200...

This study quantifies the impact of traditional and new age' provisions of preferential trading arrangements (PTAs) on merchandise trade and investment. It does so by estimating gravity models of bilateral trade and investment. It finds that recent and some past PTAs are not as benign as some...

Establishing a robust causal relationship between trade and income has been difficult. Frankel and Romer (1999) use a geographic instrument to identify a positive effect of trade on income. Rodriguez and Rodrik (2000) show that these results are not robust to controlling for omitted variables...
