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...

We introduce a simple but flexible analytical framework in which both trade in goods and trade in tasks arise. We use this framework to provide versions of the gains-from-trade and the famous four HO theorems (Heckscher–Ohlin, factor-price-equalisation, Stolper–Samuelson, and Rybczynski)...

This paper analyzes how a firm's specialization in its core products after exporting affects its factor intensity and productivity. Using Chinese manufacturing firm data for the 1998–2007 period, we find that firms become less capital-intensive but more productive after exporting, compared to...

Most of the expansion of global trade since 1980 has been of the North–South kind — between capital-abundant developed and labour-abundant developing countries. Based on this observation, I argue that the recent growth of world trade is best understood from a factor-proportions perspective....

This paper uses detailed household expenditure and firm production data to study the welfare consequences of the blockade imposed on the Gaza Strip between mid-2007 and mid-2010. Using the West Bank as a counterfactual economy, we find that welfare declined by 14%–27%. Moreover, households...

This paper derives a micro-founded gravity equation based on a translog demand system that allows for flexible substitution patterns across goods. In contrast to the standard CES-based gravity equation, translog gravity generates an endogenous trade cost elasticity. Trade is more sensitive to...

Lumpiness of production factors within a country might overturn the Heckscher–Ohlin (HO) model's predictions for the factor content of trade. Trade patterns, as predicted by this model, can both be magnified or reversed by uneven concentration of production factors within a country. Cities are...

The breakdown of global factor price equalization, or a single-cone world, is a central concern in various fields of economics. This paper examines the empirical validities of the following two claims: 1) the multiple-cone Heckscher–Ohlin (HO) model fits better than does the single-cone HO...

This paper revisits Trefler and Zhu's (2005, 2010) (TZ) empirical examination of the factor content of trade in the presence of international differences in production techniques and trade in inputs. In this framework, knowing the bilateral details of each country's input–output structure is...

This paper examines how production techniques differ across countries, factors, and industries and considers its implications for previous empirical evidence on the Vanek prediction. I find that production techniques differ substantially across countries and factors, but differ much less across...
