| Outline of Final Research Achievements |
First, this project designed optimal pay-as-you-go pension and child allowances when the population growth rate and an old agent's retirement behavior are endogenously determined. This suggests that it is necessary to take an old agent's retirement behavior into account when people design public policies. Second, I analyzed how individual borrowing constraints affect his/her fertility behavior analytically. In this project, I showed the possibility that the fertility rate could rise when the financial market is not perfect. It is good for an individual to have a child if he/she can borrow more easily, while capital accumulation drops if an individual borrows too much. This trade-off is a key to determine an individual's fertility behavior.
