The optimal subsidy to private transfers under moral hazard

Private income transfers are increasingly viewed (is an alternative to government income transfers such as social insurance and foreign aid. This paper models the incentive affects of government-subsidized private transfers and finds that although there is a significant welfare benefit to subsidizing private transfers, there is also a significant welfare cost. It is shown analytically, as well as through simulations, that the optimal subsidy to private transfers falls when the market reaction is taken into consideration.
