Outline of Final Research Achievements

Japan is currently facing an aging population and fewer children, and it is forecasted that this trend will continue after this. This research project has analyzed the effects of the family policy of child allowances, using an extended lifecycle simulation model with endogenous fertility. Simulation results show that the policy of increases in government child subsides is desirable from the long-run perspective because the policy can improve the welfare of all generations by appropriate fund transfers. However, the analysis also suggests that the recommended family policy is difficult to be implemented under the current Japanese voting system, which reflects the situation that is often criticized as the "Silver Democracy."
