Educational Assortative Mating and Household Income Inequality
利用丹麦、德国、挪威、英国和美国的数据，研究教育同质婚的程度、演变及跨国差异，并分解其对家庭收入不平等的影响，发现同质婚解释了部分横截面不平等，但对时间趋势影响很小。
We use data from Denmark, Germany, Norway, the United Kingdom, and the United States to document the degree of educational assortative mating, how it evolves over time, and the extent to which it differs between countries. This descriptive analysis motivates and guides a decomposition analysis in which we quantify the contribution of various factors to the distribution of household income. We find that assortative mating accounts for a nonnegligible part of the cross-sectional inequality in household income in each country. However, changes in assortative mating over time barely move the time trends in household income inequality.
