Population aging puts significant pressure on social security systems that are based mainly on a pay-as-you-go (PAYG) formula and determined by the political process in which both retirees and future retirees participate. This paper demonstrates that in an economic and demographic steady state,...

Redistribution is an inevitable feature of collective pension schemes and economic experiments have revealed that most people have a preference for redistribution that is not merely inspired by self-interest. Interestingly, little is known on how these preferences interact with preferences for...

Redistribution is an inevitable feature of collective pension schemes. It is still largely an open question what people‘s preferences are regarding redistribution - both through pensions schemes as well as more generally. It would seem that economists have little to say about this question, as...

In the presence of social dilemmas, cooperation is more difficult to achieve when populations are heterogeneous because of conflicting interests within groups. We examine cooperation in the context of a non-linear common pool resource game, in which individuals have unequal extraction capacities...

Although the crisis of the Welfare State has been evoked for quite a long time, figures show that such a phenomenon has arisen only recently. Furthermore, it is not a common feature in all developed countries. This paper aims at explaining these two empirical facts. We use an overlapping...

Using a capital-skill complementarity technology, we analytically show that an increase in the direct redistributivity of Pay-As-You-Go (PAYG) pension systems has a positive impact on wages and on wage inequalities. We also show that life expectancyinequalities play an important role in the...

In this paper we study the macroeconomic impact of a policy which changes the redistributive properties of an unfunded pension system. Using an overlapping generations model with a closed economy and heterogenous agents, we show that a weaker linkbetween contributions and benefits has an impact...
