Relative Income and Mental Health in Couples
研究妻子收入超过丈夫时对夫妻心理健康的影响，发现妻子相对收入增加会显著提高心理健康诊断概率，揭示家庭动态变化的间接成本。
Abstract The share of couples where the wife outearns the husband is increasing globally. In this paper, I examine how this dynamic affects mental health. Using data on the 2001 marital cohort in Sweden, I show that while mental health is positively associated with own and spousal income, it is negatively linked to the wife’s relative income. In the most conservative specification, the wife starting to earn more increases the likelihood of a mental health diagnosis by 8%–11%. This represents a significant indirect cost of changes in family dynamics.
