This study uses data from the 1988 to 2006 General Social Survey (GSS) to examine the effects of sexual orientation on earnings. Previous research using the GSS has found that lesbians earn 18%–23% more than similarly qualified heterosexual women and that wage penalties for gay men are slightly larger than the premia for lesbians. Using behavioral definitions of sexual orientation based on the previous year and the previous 5 yr of sexual activity, we find the familiar wage premia/penalties for lesbian/gay workers in our ordinary least squares estimations, but we find that these wage differences are falling over time. Furthermore, in contrast to the earlier results, for our regressions over the entire sample period, correcting for differential selection into full-time work reduces the estimated penalties for unmarried gay men and eliminates the entire wage premium for all lesbians. There is now a sizeable, though imprecisely measured, penalty for some lesbians. (JEL J1, J3, J7)
