In this paper we evaluate the long-term performance of the Polish public pension system from three perspectives: fiscal stability, intergenerational redistribution and adequacy of pension benefits. We assess the two recent public pension reforms undertaken in Poland: 1) the shift of a part of...

This paper investigates the political incentives for the design of a Pay-as-you-go public pension system in a probabilistic voting model with both far-sighted and myopic agents. People vote for a payroll tax rate determining the size of the pension system and a Bismarckian factor representing...

Chile’s pension system came under close scrutiny in recent years. This paper takes stock of the adequacy of the system and highlights its challenges. Chile’s defined contribution system was quite influential when introduced, and was taken as an example by other countries. However, it is now...

We construct a database of public pension policy changes with motivation and implementation information for ten OECD countries. Structural pension reforms, motivated by long-run sustainability concerns, often come with prolonged phase-in periods. In response to pension retrenchments implemented...

This paper takes stock of Chile's defined contribution pension system and assesses reform options aimed at increasing replacement rates. An international comparison shows that, despite being quite influential when established, it is now delivering low replacement rates relative to OECD peers, as...

This paper explores the partial equilibrium effects of the social security system in an overlapping generations economy, where individuals are distinguished according to their skills/productivity type. The emphasis is placed on building a parameterized model of the social security system in a...

Pension benefit rules depend on individual history far more than taxes do, and age plays a much larger role in pension determination than in tax determination. Apart from some simulation studies, theoretical studies of optimal tax design typically contain neither a mandatory pension system nor...

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...

In earlier literature, the suggested Pareto improvements in pay-as-you-go (PAYG) systems have relied on the presence of externalities or the possibility of intragenerational redistribution. We show that neither assumption is necessary in an economy with intergenerational trade in a fixed factor...

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...
