Does the lack of wealth constrain parents' investments in the human capital of their descendants? We conduct a nearly fifty-year followup of an episode in which such constraints would have been plausibly relaxed by a random allocation of substantial wealth to families. We track descendants of participants in Georgia's Cherokee Land Lottery of 1832, in which nearly every adult white male in Georgia took part. Winners received close to the median level of wealth - a large financial windfall orthogonal to participants' underlying characteristics that might have also affected their children's human capital. Although winners had slightly more children than non-winners, they did not send them to school more. Sons of winners have no better adult outcomes (wealth, income, literacy) than the sons of non-winners, and winners' grandchildren do not have higher literacy or school attendance than non-winners' grandchildren. This suggests only a limited role for family financial resources in the formation of human capital in the next generations in this environment and a potentially more important role for other factors that persist through family lines.
财富的匮乏是否会限制父母对其后代人力资本的投资?我们对一个事件进行了近五十年的跟踪研究,在这个事件中,大量财富被随机分配给家庭,从而有可能缓解这种限制。我们追踪了1832年佐治亚州切罗基土地彩票参与者的后代,当时佐治亚州几乎每个成年白人男性都参与了。中奖者获得的财富接近中位数水平——这是一笔与参与者潜在特征无关的巨大意外之财,而这些潜在特征可能也会影响他们孩子的人力资本。尽管中奖者的孩子比未中奖者略多,但他们送孩子上学的比例并没有更高。中奖者的儿子在成年后的状况(财富、收入、识字率)并不比未中奖者的儿子更好,而且中奖者的孙辈在识字率或上学率方面也不比未中奖者的孙辈更高。这表明在这种环境下,家庭财务资源在下一代人力资本形成中所起的作用有限,而家族传承中持续存在的其他因素可能发挥着更重要的作用。
