Disability Insurance (DI) programs have long been criticized by economists for apparent work disincentives. Some countries have recently modified their programs such that DI recipients are allowed to keep some of their benefits if they return to work, and other countries are considering similar...

In most disability insurance programs beneficiaries lose some or all of their benefits if they earn above an earnings threshold. While intended to screen out applicants with high remaining working capacity, earnings limits can also distort the labor supply of beneficiaries. We develop a simple...

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...

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...

Across the world, pension systems and their reforms are in a constant state of flux driven by shifting objectives, moving reform needs, and a changing enabling environment. The ongoing worldwide financial crisis and the adjustment to an uncertain “new normal” will make future pension systems...

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...

A key component for estimating the optimal size and structure of disability insurance (DI) programs is the elasticity of DI claiming with respect to benefit generosity. Yet, in many countries, including the United States, all workers face identical benefit schedules, which are a function of...

We study the effect of an increase in the UK state pension age from 65 to 66, a high level internationally, on labour market activity. Despite there being limited financial incentives to retire at the state pension age, we find large effects: the employment rate of 65-year-olds increased by 7.4...

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...
