The article explores how parents pass on wealth to their children, comparing the US and Korean economies. By creating a model that considers both pure and impure forms of altruism, the researchers found that when borrowing constraints are tight, parents are more likely to help financially struggling children while they are alive rather than leaving them money after they pass away. This leads to more financial support for younger children and less inheritance overall. The study shows that these borrowing constraints also contribute to differences in wealth inequality between the two countries.
