Summary

This study models two-sided search for long-term relationships, finding that individuals become less selective over time. High-fitness individuals pair first, leading to assortative mating and efficient matching.

Area of Science:

  • Game Theory
  • Evolutionary Biology
  • Microeconomics

Background:

  • Introduces a two-sided search model for long-term relationship formation.
  • Extends prior game-theoretic analysis of mating models, specifically the Kalick-Hamilton model.
  • Generalizes discrete fitness-level games to a continuous framework.

Purpose of the Study:

  • Analyze a two-sided search model for forming long-term relationships.
  • Investigate mating behavior with 'common' preferences (utility based on partner's type).
  • Establish existence, uniqueness, and characteristics of equilibrium strategies.

Main Methods:

  • Developed a continuous, two-sided search model.
  • Employed game theory to analyze equilibrium strategies.
  • Examined conditions for unique and multiple equilibria.

Main Results:

  • Established the existence of equilibrium strategy pairs.
  • Demonstrated that individuals become less choosy over time in all equilibria.
  • Observed that high-fitness individuals pair first, followed by lower-fitness individuals (assortative mating).

Conclusions:

  • The model supports assortative mating through a process of decreasing selectivity.
  • Multiple equilibria can exist, including mixed strategy equilibria under specific distribution conditions.
  • Equilibria can lead to matching within fitness bands when distributions are unknown.
