Human Capital Spillovers in Families: Do Parents Learn from or Lean on Their Children?
研究儿童学习某种人力资本如何影响成年家庭成员的学习或依赖行为，利用加州英语沉浸式教学政策发现，儿童英语水平提高反而降低了同住成年人的英语学习动力。
I model how children's acquisition of a given form of human capital incentivizes adults in their household to either learn from them (if children can teach the skill to adults, adults' cost of learning falls) or lean on them (if children's human capital substitutes for that of adults in household production, adults' benefit from learning falls). Using variation in compliance with an English-immersion mandate in California schools, I find that English instruction improved immigrant children's English proficiency but discouraged adults living with them from acquiring the language. Whether family members "learn" or "lean" affects the externalities associated with education policies.
