This paper provides a unified treatment of externalities associated with fertility and human capital accumulation within pay-as-you-go pension systems. It considers an overlapping generations model in which every generation consists of high earners and low earners with the proportion of types...

This paper studies public provision of long term care insurance in a world in which family assistance is (i) uncertain and (ii) endogenous depending on the time parents spend raising their children. Public benefits will be paid in case of disability but cannot be combined with self-insurance or...
