Using data on user attributes and interactions from an online dating site, we estimate mate preferences, and use the Gale-Shapley algorithm to predict stable matches.The predicted matches are similar to the actual matches achieved by the dating site, and the actual matches are approximately efficient.
Does mate selection differ when those looking are presented with an almost overwhelming number of potential partners, but limited to a few photos, statistics, and an introductory paragraph about each one? In one survey of Australian online daters, 85% said they would not contact someone without a posted photo, so physical appearance is indeed important (Fiore et al., 2008).
Out-of- sample predictions of offline matches, i.e., marriages, exhibit assortative mating patterns similar to those observed in actual marriages.
Thus, mate preferences, without resort to search frictions, can generate sorting in marriages.
