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...

This paper uses 68 measures of trade policy and trade liberalization to ask if membership in theWorld Trade Organization (WTO) and its predecessor the General Agreement on Tariffs and Trade (GATT) is associated with more liberal trade policy. Almost no measures of trade policy are significantly...

In light of the substantial movement towards trade liberalization during the postwar period, this paper attempts to determine if, and when, countries experienced statistically significant changes in the paths of their export-GDP and import-GDP ratios. We find that: (1) most trade ratios...

Casual empiricism suggests that additive trade costs, such as quotas, per-unit tariffs, and, in part, transportation costs, are prevalent. In spite of this, we have no broad and systematic evidence of the magnitude of these costs. We develop a new empirical framework for estimating additive...

In this paper, I survey the recent theoretical literature that incorporates heterogeneous labor into models of international trade. The models with heterogeneous labor have been used to study how talent dispersion can be a source of comparative advantage, how the opening of trade affects the...

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 study a simple, tractable model of labor adjustment in a trade model that allows us to analyze the economy's dynamic response to trade liberalization. Since it is a neoclassical market-clearing model, we can use duality techniques to study the equilibrium, and despite its simplicity a rich...

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,...

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...
