This paper summarizes and assesses recent studies on the impact of current trends in trade and direct investment on employment and wages in OECD countries. The general conclusion is that such factors as changes in labour supplies, technology and demand are more important than changes in trading...

We study how opening to trade affects economic growth in a model where heterogeneous firms can adopt new technologies already in use by other firms in their home country. We characterize the growth rate using a summary statistic of the profit distribution—the mean-min ratio. Opening to trade...

This paper evaluates how much of the economics profession has evaluated the evidence on the relationship between international trade and economic growth. The paper highlights the basic approaches to the trade and growth question that the literature has adopted. The case is made that more...

The postwar expansion of trade among the industrial countries has not had the strong distributional effects which standard models of trade would have led us to expect. This paper develops a model which attempts to explain this observation, while at the same time making sense of some other...

This paper builds a dynamic industry model with heterogeneous firms that explains why international trade induces reallocations of resources among firms in an industry. The paper shows how the exposure to trade will induce only the more productive firms to enter the export market (while some...

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...

This paper examines the interaction between relative factor abundance and income-induced policy differences in determining the pattern of trade and the effect of trade liberalization on pollution. If a rich and capital abundant North trades with a poor and labor abundant South, then free trade...

By the end of 1991, Czechoslovakia, Hungary and Poland have achieved a substantial degree of openness to foreign trade. In all three countries, trade is now de-monopolized and licensing and quotas playa very small role. Exchange controls have virtually disappeared for current-account...

Melitz (2003) demonstrates that greater trade openness raises industry productivity via a selection effect and via a production re-allocation effect. Our comment points out that the set-up assumed in the Melitz model displays a trade off between static and dynamic efficiency gains. That is,...

Quantitative results from a large class of structural gravity models of international trade depend critically on the elasticity of trade with respect to trade frictions. We develop a new simulated method of moments estimator to estimate this elasticity from disaggregate price and trade-flow data...
