演講摘要 : We analyse optimal disability insurance in the presence of unobserved health shocks and unobserved informal child care activities. We show how a combination of lump sum taxation and child care subsidies on formal child care can implement the constrained efficient allocation as though the social planner could observe informal child care activities. In the case of multiple health types, the optimal subsidies follow a sliding scale with increasing subsidies for lower family types. We then calibrate an overlapping generations model with child care needs to features of the US economy. Optimal benefits are higher for families with younger children and with higher child care needs. Optimal average tax rate is lower for healthy families as compared to the US average tax rate and vice versa for disabled families. We also find that adopting the optimal scheme can lead to sizeable cost savings.
