The difference in marriage rates between black and white Americans is striking. Wilson (1987) suggests that a skewed sex ratio and higher rates of incarceration and unemployment are responsible for lower marriage rates among the black population. In this paper, we take a dynamic look at the Wilson Hypothesis. Incarceration rates and labor market prospects of black men make them riskier spouses than white men. We develop an equilibrium search model of marriage, divorce, and labor supply in which transitions between employment, unemployment, and prison differ by race, education, and gender.
