This paper shows the effects on a pay-as-you-go pension system of the demographic change in the standard overlapping generations model. Firstly, we consider a setting with exogenous fertility and then a model with endogenous fertility. In both cases, population ageing due to increased longevity...

Heterogeneity in longevity between socioeconomic groups is increasingly documented for developed economies and is reviewed in the paper. Heterogeneity in life expectancy disaggregated by main socioeconomic characteristics - such as age, gender, race, health, education, profession, income, and...

The effects of pension policies on fertility have been examined in the overlapping generations (OLG) model of unitary household in which no heterogeneity exists between the wife and the husband. This paper departs from the OLG model and focuses on the marital bargaining arising from the...

In this paper we consider the effects of population aging on a pay-as-you-go financed defined contributions pension scheme. We show that when retirement decisions are endogenous, aging increases the retirement age and the steady state level of capital. The effect on pension payouts is in general...

The paper re-examines the idea that a family can be viewed as a community governed by a self-enforcing constitution, and extends existing results in two directions. First, it identifies circumstances in which a constitution is renegotiation-proof. Second, it introduces parental altruism. The...

This paper studies retirement and child support policies in a small, open, overlapping-generations economy with PAYG social security and endogenous retirement and fertility decisions. It demonstrates that neither fertility nor retirement choices necessarily coincide with socially optimal...

We study how childbirth increases the likelihood of young, working mothers to claim disability insurance and how paternity leave could ease this effect. Our event study analysis uses Belgian data to show that the incidence rate of disability across gender only diverges after first-time...

This paper demonstrates that the link between heterogeneity in longevity and lifetime income across countries is mostly high and often increasing; that it translates into an implicit tax/subsidy, with rates reaching 20 percent and higher in some countries; that such rates risk perverting...

We set up an overlapping generations model with endogenous fertility to study pensions policies in an ageing economy. We show that an increasing life expectancy may not be detrimental for the economy or the pension system itself. On the other hand, conventional policy measures, such as...

In many policy areas it is essential to use the best estimates of life expectancy, but such estimates are vital to most areas of pension policy - from indexed access age and the calculation of initial benefits to the financial sustainability of pension schemes and the operation of their...
