Between 1964 and 2000, the intercounty migration rate of married couples declined by 15%. Concurrently, female labor force participation and the relative wages of women increased. In 1964, 36% of married households had both spouses in the labor force and women earned only 50% of the wages of men. Over the following 36 years, the fraction of dual earner households increased to 75% and women's earnings rose to 64% of men's. Using a two location household level search model of the labor market, we show that both the increase in dual earner households and the rise in women's wages contributed significantly to the decline in the migration rate of married households, with each explaining 55% and 16% of the decline, respectively. In addition, we show that the co-location problem has important implications for estimates of lifetime earnings inequality.

1964 年至 2000 年间，已婚夫妇的跨县迁移率下降了 15%。与此同时，女性劳动力参与率和女性的相对工资有所增加。1964 年，36% 的已婚家庭的配偶双方都在工作，而女性的工资仅为男性的 50%。在接下来的 36 年里，双职工家庭的比例上升到 75%，女性的收入上升到男性的 64%。使用劳动力市场的两地家庭层面搜索模型，我们发现双职工家庭的增加和女性工资的上升都对已婚家庭的迁移率下降做出了显着贡献，分别解释了55%和16%的下降，分别。此外，
