The boundary discontinuity method of causal inference may yield misleading results if a policy's impacts do not stop at the border of the implementing jurisdiction. We use geographically precise longitudinal employment data documenting worker job-to-job mobility to study policy spillovers in the...

This paper investigates the effect of entrepreneurs' personal income tax situations on their use of labor. We analyze the income tax returns of a large number of sole proprietors before and after the Tax Reform Act of 1986 and determine how the substantial reductions in marginal tax rates...

A rapidly growing literature examines the impact of immigrants on the labor market outcomes of native-born Americans. However, the impact of immigration on natives in self-employment has not been examined, despite the over-representation of immigrants in that sector. We first present a new...

We examine trends in self-employment among white and black men from 1910 to 1990 using Census and CPS microdata. Self-employment rates fell over most of the century and then started to rise after 1970. For white men, we find that the decline was due to declining rates within industries, but was...

Previous studies tend to find that immigration has a weak negative effect on the employment and earnings of native-born workers. These studies overlook the effect of immigration on an important sector of the labor force, the self- employed. Anecdotal evidence suggests that immigrants, especially...

Employment and hours appear far more cyclical than dictated by the behavior of productivity and consumption. This puzzle has been called "the labor wedge" -- a cyclical intratemporal wedge between the marginal product of labor and the marginal rate of substitution of consumption for leisure. The...

In the 1980s, many U.S. cities initiated programs reserving a proportion of government contracts for minority-owned businesses. The staggered introduction of these set-aside programs is used to estimate their impacts on the self-employment and employment rates of African-American men. Black...

The social and the private returns to education differ when education can increase productivity, and also be used to signal productivity. We show how instrumental variables can be used to separately identify and estimate the social and private returns to education within the employer learning...

We use confidential and restricted-access data from the Kauffman Firm Survey and matched administrative data on credit scores to explore racial disparities in access to capital for new business ventures. The novel results on racial inequality in startup financing indicate that black-owned...

Between the Civil War and the turn of the nineteenth century there were many prominent African American jockeys. They rode winners in all of the Triple-Crown races. But at the turn of the century they were forced out. This paper uses a new data set on the Triple-Crown races, which includes odds...
