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...

Recent studies find that observational returns to rural-urban migration are near zero in three developing countries. We revisit this result using panel tracking surveys from six countries, finding higher returns on average. We then interpret these returns in a multi-region Roy model with...

Quantitative results from a large class of structural gravity models of international trade depend critically on a single parameter governing the elasticity of trade with respect to trade frictions. We provide a new method to estimate this elasticity and illustrate the merits of our approach...

How has the development of new trade models changed our understanding of the welfare gains from trade? Answering this question depends solely on estimates of the trade elasticity obtained using techniques applicable across different models. In this paper we build on the methods of Simonovska and...

This paper studies international technology and idea flows and their effects on growth and the welfare gains from openness. We analyze a model where producers decide either to acquire productivity-increasing ideas through search or to produce domestically and potentially for export with their...

Cross-country labor productivity differences are large in agriculture and much smaller in non-agriculture. We argue that these relative productivity differences arise when subsistence consumption needs prevent workers in poor countries from specializing in the sector in which they are most...
