This paper concerns redistribution and public good provision under asymmetric information, which are here ingredients of a policy-problem facing each member state (nation) of an economic federation with decentralized leadership. Each member state is assumed to have its own redistributive policy...

This paper develops a dynamic model with endogenous labor supply, savings and health capital, where the consumers differ in ability as well as suffer from a self-control problem generated by quasi-hyperbolic discounting. The purpose is to analyze how a paternalistic government, which implements...
