Low fertility rates combined with increases in early retirement pose a serious challenge to the sustainability of social security systems in most industrialized countries. Therefore, it is important for policy makers to understand the determinants of early retirement and especially the role that...

The paper develops an overlapping generations model with probabilistic aging of households. We define age as a set of personal attributes such as earnings potential, health and tastes that are characteristic of a person's position in the life-cycle. In assuming a limited number of different...

We use a unique dataset on individual retirement decisions in Swiss pension funds to analyze the choice between an annuity and a lump sum at retirement. Our analysis suggests the existence of an "acquiescence bias", meaning that a majority of retirees chooses the standard option offered by the...

The demographic transition in industrialized countries poses challenges to the pension system which is essentially organized according to the pay-as-you-go principle in most countries. This paper aims at analyzing two proposals for pension reform in a theoretical model that endogenously explains...

Previous empirical literature has shown a substantial extent of work disincentives in the Disability Insurance (DI). While its focus has been on the inflow into DI and on increases in benefits, this study focuses on a partial benefit cut and on existing beneficiaries. The partial benefit...

Disability insurance (DI) beneficiaries lose some of their benefits if their earnings exceed certain thresholds (“cash-cliffs”). When this reduction is too high, this implicit taxation of earnings is considered to be one of the prime reasons for the low outflow from DI. This paper analyzes a...

This paper studies the quantitative impact of aging on the financing of social security and the public sector in Switzerland. Demographic projections forecast a doubling of the dependency ratio until 2050 as well as an increase of 10% in total population due to longer life expectancy. We use a...

This paper investigates the dynamic consequences of demographic change and various pension reform scenarios for Austria. The analysis is based on a computable overlapping generations model with life-cycle labor supply, savings, and search unemployment. The public sector is decomposed into...

The labor market effects of pension reform stem from retirement behavior and from job search and hours worked of prime age workers. This paper investigates the impact of four often proposed policy measures for sustainable pensions: strengthening the tax benefit link, moving from wage to price...

This paper analyzes a recent ballot in which two virtually identical popular initiatives, both demanding a decrease in the legal age of retirement in Switzerland, led to differences in approval rates of nearly seven percentage points. Based on this unique natural experiment, the existence of...
