This paper analyzes how the legalization of same-sex marriage in the U.S. affected gay and lesbian couples in the labor market. Results from a difference-in-difference model show that both partners in same-sex couples were more likely to be employed, to have a full-time contract, and to work longer hours in states that legalized same-sex marriage. In line with a theoretical search model of discrimination, suggestive empirical evidence supports the hypothesis that marriage equality led to an improvement in employment outcomes among gays and lesbians and lower occupational segregation thanks to a decrease in discrimination towards sexual minorities.
