In this paper, we analyse the effects of demographic change on a PAYG pension system, financed with a defined contribution scheme. In particular we examine the relationship between retirement, fertility and pensions in a three-period overlapping generations model. We focus on both the case of...

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...

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...

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...

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...

In a model where longevity increases with average human capital, self-fulfilling prophecies of ageing can occur. If agents expect a low life expectancy they invest less in education, thus generating low human capital and longevity. As a result, policies that affect longevity expectations may be...

Economic and demographic outcomes are determined jointly in a dynamic general equilibrium model of longevity, fertility and growth. Reproductive agents in overlapping generations mature safely through two periods of life and face an endogenous probability of surviving for a third period. Given...

This paper sets up an OLG economy with endogenous life expectancy to study how fiscal policy that redistributes between generations can open the door to sunspot equilibria. Agents invest independently in their own human capital, produce and consume output, and receive a pension upon retirement....
