Dating Preferences and Meeting Opportunities in Mate Choice Decisions
利用独特数据集，研究男女在关系初期如何根据年龄、体重等身体特征进行匹配，发现相遇机会对约会选择有重要影响。
Much empirical evidence shows that female and male partners look alike along a variety of attributes. It is however unclear how this positive sorting comes about, because marriage is an equilibrium outcome arising from a process that entails searching, meeting and choosing one another. This study takes advantage of a unique data set to shed light on the forces driving choices at the earliest stage of a relationship. Both women and men value physical attributes, such as age and weight, and reveal that their dating choices are assortative along several traits. Importantly, meeting opportunities are found to have a substantial role in determining dating proposals.
