Using an OLG model with skill uncertainty and private savings, we investigate whether an optimally designed set of public pension transfers can usefully supplement a nonlinear labor income tax as a welfare-enhancing policy instrument. We consider a Mirrleesian setting where agents' skills are...

We study the sustainability of pension systems using a life-cycle model with distortionary taxation that sets an upper limit to the real value of tax revenues. This limit implies an endogenous threshold dependency ratio, i.e. a point in the cross-section distribution of the population beyond...

In this paper, we consider how the hours of work and retirement age ought to respond to a change in the uncertainty of the length of life. In a first best framework, where a benevolent government exercises perfect control over the individuals' labor supply and retirement-decisions, the results...

In this paper, we consider how the retirement age as well as a tax financed pension system ought to respond to a change in the standard deviation of the length of life. In a first best framework, where a benevolent government exercises perfect control over the individuals' labor supply and...

We investigate the responsiveness of individual retirement decisions to changes in financial incentives. A reform increased women's normal retirement age (NRA) in two steps from age 62 to age 63 first and then to age 64. At the same time retirement at the previous NRA became possible at a...

This paper studies the impact of recent changes in second pension pillars of three Central and Eastern European Countries on the deficit and implicit debt of their full pension systems. The paper seeks to answer the following questions: what is the impact on the sustainability of Poland's...

This paper analyzes the welfare effects of the Italian social security system in an economy with uncertainty on wages, financial market returns and life expectancy. The introduction of a pension system reproducing the Italian statutory scheme turns out to decrease ex-ante individual welfare,...

This paper considers the quantitative role of growth in the size of the social security program in contributing to the collapse of personal saving in the U.S. over the last few decades. Using a calibrated, general equilibrium life-cycle model this paper shows that social security may not be to...

We explore the benefits of intergenerational risk-sharing through both private funded pensions and via the public debt. We use a multi-period overlapping generations model with a PAYG pension pillar, a funded pension pillar and a government. Shocks are smoothed via the public debt and variations...

This paper discusses mandatory participation in Dutch occupational pension schemes. While mandatory participation is a historical feature of most second-pillar pension arrangements, some recent developments may affect the case for mandatory participation. The main ones are the revision of the...
