This paper studies the mechanism of international transmission of exchange rate shocks within a 3-country Center-Periphery model, providing a choice-theoretic framework for the policy analysis and empirical assessment of competitive devaluations. If relative prices and terms of trade exhibit...

This paper characterizes the effects of reserve requirements on financial loans in the presence of moral hazard on the lender side (i.e., the anticipation that the taxpayer will bailout lending banks if large default will occur) and sovereign risk on the borrower side. The impacts of such...

Classic trade questions are reconsidered by generalizing a factor-proportions model to multiple countries, multi-stage production, and country-specific trade costs. We derive patterns of production specialization and trade for a matrix of countries that differ in relative endowments (columns)...

This paper develops a variant of the IMF's Global Economic Model (GEM) suitable to analyze macroeconomic dynamics in open economies, and uses it to assess the effectiveness of Taylor rules and Inflation-Forecast-Based (IFB) rules in stabilizing variability in output and inflation. Our findings...

In an economy with imperfect labor contracts, differences in the distribution of human capital are an independent source of comparative advantage. I study a world economy with two sectors, one where output is produced by teams and another where individuals can work alone. When workers' abilities...

We develop a model to study the behavior of firms in a Free Trade Area with Rules of Origin and the consequences of this behavior on the market equilibrium and outcome. We show that firms will choose to specialize, and that an FTA with strict ROOs on the intermediate good raises imports and...

Most international commerce is carried out by multinational firms, which use their foreign affiliates both to serve the market of the host country and to export to other markets outside the host country. In this paper, I examine the determinants of multinational firms' location and production...

We develop a quantifiable multi-country sourcing model in which firms self-select into importing based on their productivity and country-specific variables. In contrast to canonical export models where firm profits are additively separable across destination markets, global sourcing decisions...

This paper surveys the theoretical and empirical literature on the relationship between the spatial distribution of economic activity and transportation costs. We develop a multi-region model of economic geography that we use to understand the general equilibrium implications of transportation...

This paper analyzes pharmaceutical pricing between and within countries to achieve second best static and dynamic efficiency. We distinguish countries with and without universal insurance, because insurance undermines patients' price sensitivity, potentially leading to prices above second-best...
