I examine the causes and the consequences of differences in labor market outcomes across local labor markets within a country. The focus is on a long-run general equilibrium setting, where workers and firms are free to move across localities and local prices adjust to maintain the spatial...

A large literature has documented a significant increase in the difference between the wage of college graduates and high school graduates over the past 30 years. I show that from 1980 to 2000, college graduates have experienced relatively larger increases in cost of living, because they have...

Using box-office data for all movies released between 1982 and 2000, I test the implications of a simple model of social learning in which the consumption decisions of individuals depend on information they receive from their peers. The model predicts different box office sales dynamics...

What is the effect of an increase in the overall level of human capital on the economy of a city? Although much is known about the private return to education, much less is known about the more important question of what happens to productivity, wages and land prices when the aggregate stock of...

I assess the magnitude of human capital spillovers in US cities by estimating plant-level production functions. I use a unique firm worker matched dataset, obtained by combining the Census of Manufacturers with the Census of Population. After controlling for a plant's own human capital, plant...

Economists have speculated for at least a century that the social return to education may exceed the private return. In this paper, I estimate spillovers from college education by comparing wages for otherwise similar individuals who work in cities with different shares of college graduates in...

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...

Income differences across US cities are well documented, but little is known about the level of standard of living in each city--defined as the amount of market-based consumption that residents are able to afford. In this paper we provide estimates of the standard of living by commuting zone for...
