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...

In a North–South vertically differentiated duopoly we analyze (i) the effects of parallel import (PI) policies on price competition and (ii) the interdependence of national PI policies. Prices can be higher in the North if both countries permit PIs relative to when only the South does. If...

The proliferation of preferential trade agreements has resulted in a complex system of preferences in which market access conditions are often discriminatory. In this paper we investigate how market access conditions have evolved between 2000 and 2009, and how this has affected international...

We derive a micro-founded measure of bilateral trade integration that is consistent with a broad range of leading gravity models. This measure accounts for cross-industry heterogeneity by incorporating substitution elasticities estimated at the industry level. We then use it to provide a...

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 incorporates search frictions with endogenous job creation and destruction into a two country dynamic stochastic general equilibrium model to explain two macroeconomic facts. First, since the 1980s, European unemployment rates have risen substantially above USA levels. Second, the...

This paper develops an information-based theory of international currency based on search frictions, private trading histories, and imperfect recognizability of assets. Using an open-economy search model with multiple competing currencies, the value of each currency is determined without...

In theory, nominal exchange rate movements can lead to “expenditure switching” when they generate changes in the relative prices of goods across countries. This paper explores whether the expenditure-switching role of exchange rates has changed in the current episode of significant global...

Motivated by recent empirical work, this paper formalizes a theory of competitive savings — an arms race in household savings for mating competition that is made more fierce by an increase in the male-to-female ratio in the pre-marital cohort. Relative to the empirical work, the theory can...
