Mate Markets: How Populations and Behavior Shape Online Dating Experiences
Both academia and popular culture recognize that romantic relationships are pursued within a market. The language laypeople use to talk about mate search - "he's a hot commodity"; "she's out of your league" - implies scarcity, competition, and a hierarchy of desirability. Classic works in economics and mathematics provide models of how mate preferences aggregate into observed matches. But these studies treat relationship markets as abstract, undifferentiated entities. This project uses a rich trove of activity data from multiple online dating sites to understand why dating experiences among men and women vary markedly across cities.
Building on theoretical and empirical work in behavioral ecology, I focus on two distinct classes of behavior: mate choice (i.e., preferences and choosiness) and various forms of competition. My study reveals how dating markets shape men and women's online romantic experiences. They do so both directly, by constraining the type and number of people one is exposed to, and indirectly, through the dynamic interplay between users' behavior and experience. I propose a general framework for understanding how social contexts interact with human behavior.
