In an overlapping generations experiment with multiple families participants can support their parents directly and thereby reduce their tax burden or rely on tax-financed old-age support. State productivity is captured by the factor with which total tax revenues are multiplied to determine...

We give an account of an overlapping-generations experiment with multiple families in which voluntary transfers can take the form of support to the elderly or grants to children. Support to the old is a purely intergenerational (intra-family) transfer, whereas grants to children also involve an...

Recent theoretical work shows that folk theorems can be developed for infiniteoverlapping generations games. Cooperation in such games can be sustained as aNash equilibrium. Besides the efficient cooperative equilibrium there is alsothe inefficient non-cooperative equilibrium. This paper...
