Investment in Human and Nonhuman Capital, Transfers Among Siblings, and the Role of the Government
探讨父母无法强制兄弟姐妹间转移支付对资源配置效率的影响，发现当子女能力不同时，这种转移对实现最优解是必要的；若无此转移，对劳动收入征税和对遗产补贴是有效的次优工具，而补贴人力或物质资本投资则不可取。
The implications for efficient allocation of parents' inability to force transfers among siblings are explored. When there are differences in abilities of children within families, such transfers may be necessary to achieve a first-best solution. In the absence of such transfers, a tax on earned income and a subsidy to inheritance are useful second-best tools, whereas subsidies to investments in human capital or physical capital are not desirable.
