"Beyond the Melting Pot": Cultural Transmission, Marriage, and the Evolution of Ethnic and Religious Traits*
用经济学模型分析民族和宗教特征如何通过家庭社会化与婚姻选择代际传递，发现少数群体会更努力寻找同族配偶并投入更多资源教育子女，最终导致文化多样性的稳定共存。
This paper presents an economic analysis of the intergenerational transmission of ethnic and religious traits through family socialization and marital segregation decisions. Frequency of intragroup marriage (homogamy), as well as socialization rates of religious and ethnic groups, depend on the group's share of the population: minority groups search more intensely for homogamous mates, and spend more resources to socialize their offspring. This pattern generally induces a dynamics of the distribution of ethnic and religious traits which converges to a culturally heterogeneous stationary population. Existing empirical evidence bearing directly and indirectly on the implications of the model is discussed.
