Tough love and intergenerational altruism

Vipul Bhatt, Masao Ogaki

Research output: Chapter in Book/Report/Conference proceedingChapter


This chapter develops and studies a tough love model of intergenerational altruism. We model tough love by modifying the Barro-Becker standard altruism model in two ways. First, the child's discount factor is endogenously determined, so lower childhood consumption leads to a higher discount factor later in life. Second, the parent evaluates the child's lifetime utility with a constant high discount factor. Our model predicts that parental transfers will fall when the child's discount factor falls. This is in contrast with the standard altruism model, which predicts that parental transfers are independent of exogenous changes in the child's discount factor.
