In contrast to what several papers have argued recently, we show that firm heterogeneity fosters agglomeration of economic activity. If firms are more similar with respect to their total factor productivity, each company faces a lower propensity to export. This renders the home market more...

Is the variation in bilateral trade flows across countries primarily due to differences in the number of exporting firms (the extensive margin) or in the average size of an exporter (the intensive margin)? And how does this affect the estimation and quantitative implications of the Melitz (2003)...

We provide a novel intuition for the observation that many brand manufacturers have restricted their retailers' ability to resell brand products online. Our approach builds on models of salience according to which price disparities across distribution channels guide a consumer’s attention...

Firms and workers predominately match via job postings, networks of personal contacts or the public employment agency, all of which help to ameliorate labor market frictions. In this paper we investigate the extent to which these search channels have differential effects on labor market...

New firm location decisions, relative to incumbents may be based on a choice between two types of advantages: natural advantages or those that arise from social embeddedness, the latter of which may particularly include knowledge spillovers. We analyze the relative importance of geographically...

Ever since Sjaastad (1962), researchers have struggled to quantify the psychic cost of migration. We monetize psychic cost as the wage premium for moving to a culturally different location. We combine administrative social security panel data with a proxy for cultural difference based on...

In a two-country reciprocal dumping model, with one country unionized, we analyze how wage setting and firm location are influenced by trade liberalization. We show that trade liberalization can induce FDI, which is at odds with conventional theoretical wisdom and cannot happen in a...

The U.S. Environmental Protection Agency (USEPA) maintains networks of pollution monitors for two basic purposes: to check and enforce the attainment of national ambient air quality standards (NAAQS) and to provide useful data for studying pollution and its effects. These purposes imply...

This paper presents a model in which final goods producers outsource intermediate input production. Intermediate inputs are differentiated and their production can be located at home or abroad. The model is used to examine competitive location policy in a (two-country) free trade agreement...

This paper analyzes the impact of particular loss offset limitations on intrastate and crossborder investment decisions. Investment can be realized in the investor's domestic business, in a foreign branch or in a foreign subsidiary. The relative impact on the optimal real investment alternative...
