We develop a versatile general equilibrium framework to determine the spatial distribution of economic activity on any surface with (nearly) any geography. Combining the gravity structure of trade with labor mobility, we provide conditions for the existence, uniqueness, and stability of a...

The direct benefits of infrastructure in developing countries can be large, but if new infrastructure induces in-migration, congestion of other local publicly provided goods may offset the direct benefits. Using the example of rural household electrification in South Africa, we demonstrate the...

Tax benefits to owner-occupied housing provide incentives for housing consumption, offsetting weaker disincentives of the property tax. These benefits also help counter the penalty federal taxes impose on households who work in productive high-wage areas, but reinforce incentives to consume...

What determines the distributions of skills, occupations, and industries across cities? We develop a theory to jointly address these fundamental questions about the spatial organization of economies. Our model incorporates a system of cities, their internal urban structures, and a...

We develop a dynamic labor search model where production and consumption take place in spatially distinct labor markets with varying exposure to domestic and international trade. The model recognizes the role of labor mobility frictions, goods mobility frictions, geographic factors, and...

We develop a monopolistically competitive model of trade with firm heterogeneity - in terms of productivity differences - and endogenous differences in the 'toughness' of competition across markets - in terms of the number and average productivity of competing firms. We analyze how these...

We provide estimates of the impact and long-run elasticities of tax base with respect to tax rates for four large U.S. cities: Houston (property taxation), Minneapolis (property taxation), New York City (property, general sales, and income taxation), and Philadelphia (property, gross receipts,...

This handbook chapter studies the theoretical micro-foundations of urban agglomeration economies. We distinguish three types of micro-foundations, based on sharing, matching, and learning mechanisms. For each of these three categories, we develop one or more core models in detail and discuss the...

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...

In theory, federal transfers that make household location decisions efficient should ignore local cost differences, subsidize positive externalities, and offset differences in federal-tax payments and local taxes levied on non-residents, but not local tax revenues from residents. Transfers that...
