Increases in the cost of providing health insurance must have some effect on labor markets, either in lower wages, changes in the composition of employment, or both. Despite a presumption that most of this effect will be in the form of lower wages, we document in this paper a significant effect on work hours as well. Using data from the CPS and the SIPP, we show that rising health insurance costs over the 1980s increased the hours worked of those with health insurance by up to 3 percent. We argue that this occurs because health insurance is a fixed cost, and as it becomes more expensive to provide, firms face an incentive to substitute hours per worker for the number of workers employed.

This paper examines segregation in American cities from 1890 to 1990. From 1890 to 1940, ghettos were born as blacks migrated to urban areas and cities developed vast expanses filled with almost entirely black housing. From 1940 to 1970, black migration continued and the physical areas of the ghettos expanded. Since 1970, there has been a decline in segregation as blacks have moved into previously all‐white areas of cities and suburbs. Across all these time periods there is a strong positive relation between urban population or density and segregation. Data on house prices and attitudes toward integration suggest that in the mid‐twentieth century, segregation was a product of collective actions taken by whites to exclude blacks from their neighborhoods. By 1990, the legal barriers enforcing segregation had been replaced by decentralized racism, where whites pay more than blacks to live in predominantly white areas.
