The Cultural Divide
研究文化鸿沟的演变，提出文化变迁模型并用1972-2018年美国综合社会调查数据验证，发现个体间文化异质性上升，宗教和政治取向的分歧加剧，收入与种族的分歧呈微弱U型，性别与城乡差异则持平或缩小。
Abstract We study the evolution of cultural divides both theoretically and empirically. We propose a model of cultural change where intergenerational transmission and forces of social influence determine the distribution of cultural traits in society. We conduct an empirical investigation of the evolution of cultural heterogeneity in the USA between 1972 and 2018, using the General Social Survey. In recent decades, cultural heterogeneity between individuals has risen. Cultural divides between identity groups display contrasted patterns: increasing along lines of religion and political orientation, mildly U-shaped along income and racial lines, and flat or decreasing for gender and urbanicity. We interpret these empirical findings in light of our model, arguing that changes in modes of interaction within and across groups can explain the observed dynamics of cultural heterogeneity.
