We study the urban structure of the city of Detroit. Following several decades of decline, the city's current urban structure is clearly not optimal for its size, with a business district immediately surrounded by a ring of largely vacant neighborhoods. We propose a model with residential...

This paper develops a two-region model of firm migration where moving is costly and firms have market power. In this setting, the decentralized equilibrium generates excessive inertia in firm movement relative to the 'first best' solution. Because the decentralized solution is inefficient, the...

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...

Petersburg, Virginia, prospered over two centuries as a center of production and trade. However, the city experienced economic difficulties beginning in the 1980s as a large number of layoffs at production plants in the area coincided with an erosion of retail trade in the city. Prolonged...

Using data compiled from concentrated residential urban revitalization programs implemented in Richmond, VA, between 1999 and 2004, we study residential externalities. Specifically, we provide evidence that in neighborhoods targeted by the programs, sites that did not directly benefit from...

In several recent articles, authors have regressed actual values of macroeconomic aggregates on predicted values and claimed that they were testing the rationality of expectations. This paper interprets those regressions as testing a joint hypothesis of imperfect information and rational...

Thirty years ago it appeared that the best strategy for improving economic forecasts was to build bigger, more detailed models. As the cost of computing plummeted, considerable detail was added to models and more elaborate statistical techniques became feasible. Yet dissatisfaction with...
