We examine two factors that might explain the extent of air traffic delays in the United States: network benefits due to hubbing and congestion externalities. Airline hubs enable passengers to cross-connect to many destinations, thus creating network benefits that increase in the number of...

Recent trade models determine the equilibrium distribution of firm-level efficiency endogenously and show that freer trade shifts the distribution towards higher average productivity due to entry and exit of firms. These models ignore the possibility that freer trade also alters the firm-size...

A two-region, two-firm model is developed in which firms choose the number and the regional locations of their plants. Both firms pollute and, in this context, market structure is endogenous to environmental policy. There are increasing returns at the plant level, imperfect competition between...

I survey the influence of Grossman and Hart's (1986) seminal paper in the field of International Trade. I discuss the implementation of the theory in open-economy environments and its implications for the international organization of production and the structure of international trade flows. I...

This paper investigates the urbanization of the Indian manufacturing sector by combining enterprise data from formal and informal sectors. We find that plants in the formal sector are moving away from urban and into rural locations, while the informal sector is moving from rural to urban...

We identify the impact of local firm concentration on incumbent performance with a quasi natural experiment. When Germany was divided after World War II, many firms in the machine tool industry fled the Soviet occupied zone to prevent expropriation. We show that the regional location decisions...

We examine effective tax rates (ETRs) for 9,022 multinationals from 87 countries from 2006 to 2011. We find that, despite extensive investments in international tax avoidance, multinationals headquartered in Japan, the U.S., and some high-tax European countries continue to face substantially...

In a sample of over 27 million establishments of U.S. firms with activities in more than one state, we estimate the impact of state business taxation on business activity. Only firms organized as subchapter C corporations are subject to the corporate tax code, whereas the income of partnerships,...

We analyze the impact of technology on production and trade in services, focusing on the foreign exchange market. We identify exogenous technological changes by the connection of countries to submarine fiber-optic cables used for electronic trading, but which were not laid for purposes related...

In this paper we present and solve a three-stage game of entry, location, and pricing in a spatial price discrimination framework with arbitrarily many heterogeneous firms. We provide a unique characterization of all equilibria without imposing restrictions on the distribution of marginal costs
