In developing countries, most manufacturing firms are small and located in high-density urban areas, often near congested streets. To study the determinants and implications of this location choice, we collect a novel firm survey and detailed air pollution measurements within Ugandan cities. We...

We study the number, size, and location of a firm's plants. The firm's decision balances the benefit of delivering goods and services to customers using multiple plants with the cost of setting up and managing these plants, and the potential for cannibalization that arises as their number...

This paper investigates the relation between a firm's location and its corporate finance decisions. We develop a simple model where being located within an industry cluster increases opportunities to make acquisitions, and to facilitate those acquisitions, firms within clusters maintain more...

Usually transportation/communication (t/c) considerations appear as only two in a long list of factors which determine headquarters location patterns. The research reported here singles out t/c considerations as the logical basis for headquarters location decisions. We ask: to what degree do...

The structure of a multinational firm, that is how its affiliates relate to one another, is critical for understanding where multinationals locate, how policy affects them, and their resilience to localized shocks. Here, we review the two main structures: horizontal investments which replicate...

How does a country's economic geography evolve along the development path? This paper documents recent employment growth in 18,961 regions in eight of the world's main economies. Overall, market potential is losing importance, and local density is gaining importance, as correlates of local...

How does improving access to the supply of energy affect regional specialization in manufacturing? We evaluate the long-run employment impacts of pipelines constructed by the U.S. government during World War II to transport oil and gas from the oil fields of the Southwest to wartime industrial...

We introduce a new methodology to detect and measure economic activity using geospatial data and apply it to steel production, a major industrial pollution source worldwide. Combining plant output data with geospatial data, such as ambient air pollutants, nighttime lights, and temperature, we...

We document several empirical regularities regarding the evolution of urban structure in the largest U.S. metropolitan areas over the period 1980-1990. These regularities relate to changes in resident population, employment, occupations, as well as the number and size of establishments in...
