Marriage Meets the Joneses
研究了相对收入对婚姻的影响，发现低收入男性的收入与当地中位数之比能显著预测其婚姻状况，参考群体收入每提高10%，结婚率下降2%。
This paper investigates the effect of relative income on marriage. Accounting flexibly for absolute income, the ratio between a man's income and a local reference group median is a strong predictor of marital status, but only for low-income men. Relative income affects marriage even among those living with a partner. A ten percent higher reference group income is associated with a two percent reduction in marriage. We propose an identity model to explain the results.
