Subsidy policies in a fertility choice model

This paper compares the effects that a subsidy to health expenditure or a subsidy to child-rearing costs has in a fertility choice model in which mortality is also endogenously determined. Whichever subsidy is instituted, the population growth rate rises. While a subsidy to health expenditure reduces welfare, a subsidy to child-rearing costs might increase welfare. The welfare analysis also suggests that a subsidy to health expenditure should be financed by a capital income tax, while a subsidy to child-rearing costs should be financed by a consumption tax.
