In this paper, I study the effect of economic integration with the United States on state-industry employment growth in Mexico. I disentangle the effects of two opposing forces on regional labor demand: transport-cost considerations, which, all else equal, encourage firms to relocate their...

Recent models in economic geography suggest that there may be very large numbers of equilibrium spatial structures. Simulations suggest, however, that the structures that emerge are surprisingly orderly, and often seem approximately to follow simple rules about the spacing of urban sites. This...

We assess size and scope-related economies in the global advertising and marketing services business. A translog cost function is employed wherein a firm's costs vary according to its scale and two dimensions of the scope of its operations. Parameters of the model are estimated via three stage...

When physicians own complementary medical service facilities such as clinical laboratories and imaging centers, they gain financially by referring patients to these service entities. This situation creates an incentive for the physician to exploit the consumers' trust by recommending more...

A growing literature seeks to understand how the characteristics of firms shape the manner in which they serve foreign markets. We consider an environment in which multiproduct firms can sell their products in multiple countries from multiple locations. We show that there are strong empirical...

International transactions are costly because they require investments in logistics, contracts, and the acquisition of local institutional knowledge. We posit that a portion of the fixed costs of entering a specific export market can be used toward costs of acquiring imports from that same...

Urban economics has traditionally viewed cities as having advantages in production and disadvantages in consumption. We argue that the role of urban density in facilitating consumption is extremely important and understudied. As firms become more mobile, the success of cities hinges more and...

In many cities, restaurants and retail establishments are spatially concentrated. Economists have long recognized the presence of demand externalities that arise from spatial agglomeration as a possible explanation, but empirically identifying this type of spillovers has proven difficult. We...

We document a novel stylized fact: Using data for several countries, we show that export activity is disproportionately concentrated in larger cities - even more so than overall economic activity. We account for this fact by marrying elements of international trade and economic geography. We...
