Marriage Meets the Joneses: Relative Income, Identity, and Marital Status
研究了相对收入对婚姻的影响，发现对于低收入男性，收入与当地参照组中位数的比率能显著预测婚姻状况，参照组收入提高10%与婚姻减少2%相关，并提出了身份认同模型来解释这一结果。
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 10 percent higher reference group income is associated with a 2 percent reduction in marriage. We propose an identity model to explain the results.
