For pay-as-you-go financed pension systems, claims may be calculated according to individual contributions (income) or the number of children of a family. We analyse the optimal structure of these parameters in a model with endogenous fertility. It is shown that for both structural determinants...

In this paper we analyse the possibility to construct intergenerational criteria of choice within the framework of methodological individualism. The main result of this analysis is, that intergenerational criteria as an aggregation of preferences of current and future individuals do not exist....

In an environment with asymmetric information the implementation of a first-best efficient Clarke-Groves-Vickrey (D’Aspremont-Gérard-Varet) mechanism may not be feasible if it has to be self-financing. By using intergenerational transfers, the arising budget deficit can generally be covered...
