Educational Homogamy
研究发现，教育同质婚中约一半源于人们倾向与同校或邻近学校的人结婚，另一半则直接受伴侣教育水平影响，可能反映家庭生产中的互补性。
Abstract Individuals match on length and type of education. We find that around half of the systematic sorting on education is explained by the tendency of individuals to marry someone who went to the same educational institution or to an institution near them. This may be due to low search frictions or selection of people with the same preferences into the same institutions. The residual half of the systematic sorting on education is a direct effect of partners’ education, which is potentially explained by complementarities in household production in couples with same education.
