Trends in Assortative Mating and Offspring Outcomes
研究挪威父母五十年间的择偶匹配趋势，发现匹配程度稳定但生育向高阶层倾斜，且一方阶层对子代教育就业的边际影响随另一方阶层升高而减小，整体上择偶趋势略微改善了子代平均教育就业并降低了不平等。
Abstract We study assortative mating of Norwegian parents over five decades and its consequences for offspring outcomes. Parents are characterised by the earnings decile of their parents (the offspring's grandparents) as an indicator of social class. While assortative mating has remained stable across decades, parenthood has become more skewed toward the higher classes. Examining the influence on offspring education and employment, we find that the marginal effect of one parent's class is smaller the higher is the class of the other. Overall, mating trends have contributed to slight improvements in average education and employment and reduced inequality in the offspring generation.
