Gender identity and relative income within households: evidence from Sweden*
研究瑞典家庭中妻子收入占比的分布，发现当妻子收入超过丈夫时存在下降，但排除收入相等的夫妻后下降很小且不显著，表明瑞典夫妻对性别规范的遵循较弱。
Abstract In their study of relative income within US households, Bertrand et al. (2015, Quarterly Journal of Economics 130 , 571–614) show that the distribution of the wife's share of household income drops sharply where the wife starts earning more than her husband. They attribute the drop to a gender norm prescribing that a wife's income should not exceed her husband's income. We document a similar drop in Swedish data. However, we also show that there is a spike where spouses earn exactly the same. Excluding the equal‐earning spouses, the drop is small and mostly statistically insignificant. We conclude that, if anything, we find only weak evidence that Swedish couples comply with this gender norm.
