We explore voluntary participation in pension arrangements. Individuals only participate when participation is more attractive than autarky. The bene??it 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...

The authors outline a public pension reform where contribution rates are reduced to zero over a very long horizon and in a Pareto-improving fashion.

In the present paper the effects of different pay-as-you-go pension systems on fertility decisions of a representative household are examined. Thereby, the analysis focuses especially on the interplay of parental quantity and quality decisions, introduced by Becker (1960). As it will be shown, a...

The Non-financial (Notional) Defined Contribution (NDC) PAYGO pension scheme is a recent innovation and its generic dimensions have not previously been explored in a coherent context. This paper does this. It derives and analyzes the demographic, economic and distributional properties of NDC....

As one possible solution to the well-known financing crisis of unfunded social security systems, an increase in the retirement age is a popular option. To induce workers to retire later, it has been proposed to strengthen the link between retirement age and benefit level. The present paper is...

A pay-as-you-go pension scheme is associated with positive externalities of having children and providing them with human capital. In a framework with heterogeneity in productivity, and stochastic and endogenous investment in fertility and education, we discuss internalization policies...

Many Western countries with an aging population consider reforms of their pay-as-you-go pension systems. In Sweden a new pension system has already been decided and implemented. This paper gives a brief background to the Swedish reforms in the 1990s and explains the structure of the new system.

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, the...

The book compares funded and unfunded pension schemes. This is done within a simple overlapping generations framework.

This paper considers the possibility of letting a pay-go pension system mimic a fully funded pension system. Generically, it turns out to be impossible to make a less than fully funded pension system actuarially fair on average. But a non-funded pay-go pension system can provide an actuarially...
