Why Do Wealthy Parents Have Wealthy Children?
利用被挪威家庭收养的韩国儿童数据，研究发现家庭背景对成年后的财富积累和投资行为有显著影响，即使排除基因关联，这种影响依然存在。
We show that family background matters significantly for children’s accumulation of wealth and investor behavior as adults, even when removing the genetic connection between children and the parents raising them. The analysis is made possible by linking Korean-born children who were adopted at infancy by Norwegian parents to a population panel data set with detailed information on wealth and socioeconomic characteristics. The mechanism by which these Korean-Norwegian adoptees were assigned to adoptive families is known and effectively random. This mechanism allows us to estimate the causal effects from an adoptee being raised in one type of family versus another.
