Grandma was Right: Why Cohabitation Undermines Relational Satisfaction, But Is Increasing Anyway
用博弈论模型解释已婚夫妇比同居伴侣关系满意度更高的实证发现，并利用28个工业化国家和美国50个州的数据，发现女性劳动参与率每提高10%，同居率上升6.4%至14.6%。
SUMMARY This paper uses a game theoretic model to explain empirical research which has revealed higher relational satisfaction among married couples than cohabiting couples, as well as among married couples who did not cohabit before marriage. Despite these findings, in recent decades cohabitation rates have dramatically increased in both Europe and the United States. Instrumental variables estimations on data from 28 industrialized countries and 50 U.S. states show cohabitation strongly correlated with increases in women's labor force participation, where a 10 percent increase in women's labor force participation results in a 6.4 to 14.6 percent increase in cohabitation.
