中文摘要
在青春期，同伴互动在儿童发展中变得日益核心，而父母的直接影响则逐渐减弱。尽管如此，父母仍可通过塑造子女的同伴群体继续施加影响。我们构建并估计了一个包含同伴效应与邻里效应的教养模型，其中父母会干预同伴群体的形成，并表明该模型能够刻画美国高中生在技能积累、教养方式与同伴特征方面的经验模式。我们发现，将儿童迁往更好邻里的干预措施在规模化推广后会失去效力，因为父母的均衡反应会阻碍他们与新同伴群体的成功融合。
Abstract
During adolescence, peer interactions become increasingly central to children’s development, whereas the direct influence of parents wanes. Nevertheless, parents can continue to exert leverage by shaping their children’s peer groups. We construct and estimate a model of parenting with peer and neighborhood effects where parents intervene in peer formation and show that the model captures empirical patterns of skill accumulation, parenting style, and peer characteristics among US high school students. We find that interventions that move children to better neighborhoods lose impact when they are scaled up, because parents’ equilibrium responses push against successful integration with the new peer group.
