Abstract

This paper studies the politico-economic sustainability of pay-as-you-go social security in OLG models under Markovian strategies as first studied by Forni (2005). Under logarithmic utility, the paper shows that equilibria with social security can only exist if the underlying economy is dynamically inefficient. The paper also derives the exact parametric conditions that allow for the existence of equilibria and shows that among all the admissible (arbitrary) constants that produce a Markov perfect equilibrium, the maximum constant in such set yields the only equilibrium that solves dynamic inefficiency.
