We explore the impact of rising incomes at the top of the distribution on spatial sorting patterns within large U.S. cities. We develop and quantify a spatial model of a city with heterogeneous agents and non-homothetic preferences for neighborhoods with endogenous amenity quality. As the rich...

The past thirty years have seen a dramatic decline in the rate of income convergence across states and in population flows to high-income places. These changes coincide with a disproportionate increase in housing prices in high-income places, a divergence in the skill-specific returns to moving...

We examine the effect of rising U.S. house prices on borrowing and spending from 2002 to 2006. There is strong heterogeneity in the marginal propensity to borrow and spend. Households in low income zip codes aggressively liquefy home equity when house prices rise, and they increase spending...

Regional shocks are an important feature of the U.S. economy. Households' ability to self-insure against these shocks depends on how they affect local interest rates. In the United States, most borrowing occurs through the mortgage market and is influenced by the presence of government-sponsored...

It is widely hypothesized that incomes in wealthy countries are insulated from environmental conditions because individuals have the resources needed to adapt to their environment. We test this idea in the wealthiest economy in human history. Using within-county variation in weather, we estimate...

The growth of American governments in the twentieth century included large increases in funds for social insurance and public assistance. Social insurance has increased far more than public assistance, so “rise in the social insurance state” is a far better description of the century than...

Urban change involves transformations in the physical appearance and the social composition of neighborhoods. Yet, the relationship between the physical and social components of urban change is not well understood due to the lack of comprehensive measures of neighborhood appearance. Here, we...

Inequality in U.S. housing prices and rents both declined in the mid-20th century, even as home-ownership rates rose. Subsequently, housing-price inequality has risen to pre-War levels, while rent inequality has risen less. Combining both measures, we see inequality in housing consumption...

We construct and calibrate a model of the world economy in which countries' opportunities to develop depend on their trade with advanced economies. Trade opportunities in turn depend on the relative population of the advanced and developing world. As developing countries become advanced, they...
