Peers and Culture*
研究了父母在考虑同伴影响时如何向子女传递文化，发现即使所有父母都试图传递同一种文化，文化多样性仍可持续，且父母对多元文化的需求并不保证多样性。
Abstract We analyze the evolution of culture when parents socialize children to the cultural variants that maximize child lifetime utility. Parents invest in cultural transmission by taking into account that children are also influenced by peers. We model the influence of peers by assuming that children observe different cultural variants in their peer group, assign merit to them and adopt one variant, following a probabilistic adoption rule. We show that cultural diversity is sustainable even if all parents strive to transmit the same variant. We also show that a parental demand for cultural pluralism does not guarantee cultural diversity.
