This paper explores the optimal risk sharing arrangement between generations in an overlapping generations model with endogenous growth. We allow for nonseparable preferences, paying particular attention to the risk aversion of the old as well as overall 'life-cycle' risk aversion. We provide a...

We analyse the impact of micro-founded political institutions on environmental policy and economic growth. We model an overlapping-generations economy, where individuals differ in preferences over the environment (as well as in age). Labour taxation and capital taxation is used to finance a...

We explore voluntary participation in pension arrangements. Individuals only participate when participation is more attractive than autarky. The benefit of participation is that risks can be shared with future generations. We apply our analysis to a pay-as-you-go system, a funded system without...

This Paper explores the effects of a menu of inter-generational fiscal policies (public debt financed by taxes, PAYG social security system and inheritance taxation) in an overlapping generations model with perfect altruism. It generalizes the model by Barro (1974) by introducing...

We analyze the effect of the projected demographic transition on the political support for social security, and equilibrium outcomes. Embedding a probabilistic-voting setup of electoral competition in the Diamond (1965) OLG model, we find that intergenerational transfers arise in the absence of...

In this Paper, we study the role of subsidies to fertility in ensuring the political viability of unfunded social security (SS). In our model, agents are heterogeneous in age and income. Young generations confront promises made previously by older generations, and in turn choose current levels...

Is there an economic rationale for pronatalist policies? In this paper we propose and analyze a particular market failure that may lead to inefficiently low equilibrium fertility and therefore to a need for government intervention. The friction we investigate is related to the ownership of...

We investigate intergenerational risk sharing in two-pillar pension systems with a pay-as-you-go pillar and a funded pillar. We consider shocks in productivity, depreciation of capital and inflation. The funded pension pillar can be either defined contribution or defined benefit, with benefits...

We explore intergenerational and international risk sharing in a general equilibrium multiple-country model with two-tier pensions systems. The exact design of the funded tier is key for the way in which risks are shared over the various generations. The laissez-faire market solution fails to...

We extend "economic equivalence" results, like the Ricardian equivalence proposition, to the political sphere where policy is chosen sequentially. We derive conditions under which a policy regime (summarizing admissible policy choices in every period) and a state are "politico-economically...
