In this paper we model an OLG-economy where labour supply is endogenously determined and where we assume that there are two pension systems, namely, a pay-as-you-go system and a funded system. The main question is whether there is an equilibrium involving an old-age pensions system, partly...

A model is presented that explains the mix between funded and unfunded pension systems. It turns out that total pension and the relative shares of the two systems may be explained and are determined by the population growth rate, technological growth, the time-preference discount rate, that...

Everywhere in the industrialized world, population aging is putting social security systems under financial strain. As a result, social security systems are being reformed in many countries. In particular, various countries move from pure pay-as-you-go (PAYG) systems to pension systems that...

This paper analyzes the transition from a pay-as-you-go to a fully funded pension system within the framework of endogenous growth in the presence of uncertainty. Gyárfás and Marquardt (2001) prove the possibility of a Pareto improving conversion in a certain world. Two distinct kinds of...

We explore the benefits of intergenerational risk-sharing through both private funded pensions and via the public debt. We use a multi-period overlapping generations model with a PAYG pension pillar, a funded pension pillar and a government. Shocks are smoothed via the public debt and variations...
