Effect of State and Local Sexual Orientation Anti-Discrimination Laws on Labor Market Differentials

Résumé 0

This paper presents the first quasi-experimental research examining the effect of both local and state anti-discrimination laws on sexual orientation on the labor supply and wages of lesbian, gay, and bisexual (LGB) workers. To do so, we use the American Community Survey data on household composition to infer sexual orientation and combine this with a unique panel dataset on local anti-discrimination laws. Using variation in law implementation across localities over time and between same-sex and different-sex couples, we find that anti-discrimination laws significantly reduce gaps in labor force participation rate, employment, and the wage gap for gay men relative to straight men. These laws also significantly reduce the labor force participation rate, employment, and wage premium for lesbian women relative to straight women. One explanation for the reduced labor supply and wage premium is that lesbian couples begin to have more children in response to the laws. Finally, we present evidence that state anti-discrimination laws significantly and persistently increased support for same-sex marriage. This research shows that anti-discrimination laws can be an effective policy tool for reducing labor market inequalities across sexual orientation and improving sentiment toward LGB Americans.
