Key points

  • A "same-sex penalty" exists, indicating lower gains from live-in relationships for same-sex couples.
  • Partner gender is endogenously chosen based on sexual orientation and preference trade-offs.
  • Eliminating the penalty could increase the share of same-sex couples in the U.S. by about 50% (from 1.36% to 2.04%).

Abstract

Abstract We study the mating patterns of non-heterosexual individuals, who represent a significant and increasing portion of the population, particularly among the youth. We estimate a multidimensional matching model of the marriage market where partner’s gender is endogenously chosen conditional on the agent’s sexual orientation, and is subject to trade-offs that depend on both the agents’ preferences and the pool of potential partners. We show that same-sex couples experience lower gains from live-in relationships, a “same-sex penalty”. Absent this penalty, the share of same-sex couples in the U.S. would increase by about 50% (from 1.36% to 2.04% of all couples).
