The assumption of internationally identical factor intensity techniques may be one of the major causes of the HOV model's poor performance. To relax this assumption, detailed input-output data are required to compute the factor intensity techniques used in different countries; however, these...

I argue in favor of a competitive screening approach for studying the question of coalition formation in exchange economies under asymmetric information. I obtain a new notion of core that refines Wilson (1978)'s coarse core. It is nonempty under the standard regularity conditions. I also...

This paper studies a competitive market model for trading indivisible commodities. Commodities can be desirable or undesirable. Agents' preferences depend on the bundle of commodities and the quantity of money they hold. We assume that agents have quasi-linear utilities in money. Using the...

The paper focuses on short run macroeconomic dynamics triggered by demand side shocks. In particular, the paper analyzes, in a general equilibrium framework, the impact of transitory demand side shocks on the behavior of macroeconomic variables and examines the relevance of policy instruments...

The tax reform literature, pioneered by Guesnerie [1977], uses static models but views tax reform as a dynamic process, i.e., as a policy-maker implementing incremental reforms over time. This paper studies tax reform in a dynamic version of the Diamond-Mirrlees-Guesnerie model and focuses on a...

This paper presents a theory of location choice that draws on insights from the incomplete contracts and investment flexibility (real option) literatures. We provide conditions under which human capital is more efficiently created and better utilized within industrial clusters that contain...

Trade and growth theories predict a mutual causation of innovation and exports. We test empirically whether innovation causes exports using a uniquely rich German micro dataset. To overcome the potential endogeneity, we need to identify variations in innovations that are exogenous to export...

This paper studies empirically the relationship between trade policy and individual income risk and uses the empirical estimates of this relationship to asses the welfare costs of changes in trade policy. The empirical analysis proceeds in two steps. First, longitudinal data on income of Mexican...

We use data on wages and rents in different U.S. cities to assess the amenity effects on production and consumption of cultural diversity as measured by diversity of countries of birth of city residents. We show that US-born citizens living in metropolitan areas where the share of foreign-born...

This paper studies optimal monetary policy in a small open economy under flexible prices. The paper’s key innovation is to analyze this question in the context of environments where only a fraction of agents participate in asset market transactions (i.e., asset markets are segmented). In...
