Fatter Attraction: Anthropometric and Socioeconomic Matching on the Marriage Market
构建了一个多维度匹配的婚姻市场模型，发现男性可用1%的工资增长补偿1.3个BMI单位，女性可用1年教育补偿2个BMI单位，对研究婚姻匹配和偏好权衡的经济学者有参考价值。
We construct a marriage market model of matching along multiple dimensions, some of which are unobservable, in which individual preferences can be summarized by a one-dimensional index combining the various characteristics. We show that, under testable assumptions, these indices are ordinally identified and that the male and female trade-offs between their partners' characteristics are overidentified. Using PSID data onmarried couples, we recover the marginal rates of substitution between body mass index (BMI) and wages or education: men may compensate 1.3 additional units of BMI with a 1 percent increase in wages, whereas women may compensate two BMI units with 1 year of education. © 2012 by The University of Chicago.
