This paper endogenizes the spatial distribution of infrastructure investment and transportation costs. Transportation costs between two addresses depend on cumulative infrastructure investment. In a continuous space setting with several independent countries or regions, consumers demand domestic...

We incorporate trade in tasks l a Grossman and Rossi-Hansberg (2008) into the international trade theory of fi rm organization of Marin and Verdier (2012) to examine how off shoring aff ects the way fi rms organize. We test the predictions of the model based on firm level data of 660 Austrian...

This paper develops a quantitative model of trade, military conflicts, and defense spending. Lowering trade costs between two countries reduces probability of an armed conflict between them, causing both to cut defense spending. This in turn causes a domino effect on defense spending by other...

This paper identifies a new reason for giving preferences to the disadvantaged using a model of contests. There are two forces at work: the effort effect working against giving preferences and the selection effect working for them. When education is costly and easy to obtain (as in the U.S.),...

This paper develops a novel approach to modeling preferences in monopolistic competition models with a continuum of goods. In contrast to the commonly used constant elasticity of substitution preferences, which do not capture the effects of consumer income and the intensity of competition on...

This paper explores how income distribution affects market structure, prices, and economic well-being of different consumer groups. I consider a general equilibrium model of monopolistic competition with free entry, heterogenous firms and consumers that share identical but non-homothetic...

This paper develops a novel approach to modeling preferences in monopolistic competition models with a continuum of goods. In contrast to the commonly used constant elasticity of substitution preferences, which do not capture the effects of consumer income and the intensity of competition on...

This paper quantitatively explores the role of the demand structure in explaining the relationship between an importer's per capita income and the extensive margin of bilateral trade. The underlying mechanism is based on the fact that agents expand the set of goods they consume with income. This...

This paper develops a quantitative model of trade, military conflicts, and defense spending. Trade liberalization between two countries reduces probability of an armed conict between them, causing both to cut defense spending. This in turn causes a domino effect on defense spending by other...

There is strong empirical evidence that countries with lower per capita income tend to have smaller trade volumes even after controlling for aggregate income. Furthermore, poorer countries do not just trade less, but have a lower number of trading partners. In this paper, I construct and...
