We analyze the political stability of welfare enhancing privatization of the social security. We consider an economy populated by overlapping generations, who vote on abolishing the funded system and replacing it with the pay-as-you-go scheme, i.e. "unprivatizing" the pension system. We show...

Recent reforms that aim at reducing the upcoming burdens of population ageing might seriously harm low income individuals. An increase in old-age poverty and disability will be the result. Under this prospect, the present paper quantitatively characterizes the optimal progressivity of unfunded...

In 2007 Germany has introduced a pension reform which increases the normal retirement age from currently age 65 to 67. The present study aims to quantify the macroeconomic, welfare and efficiency consequences of this reform by means of a computable general equilibrium model with overlapping...

This paper studies the redistribution and welfare effects of increasing the flexibility of individual pension take-up. We use an overlapping-generations model with Beveridgean pay-as-you-go pensions, where individuals differ in ability and life span. We find that introducing flexible pension...

Funded social security programs are particularly vulnerable to economic and financial market shocks. As a consequence of the recent crisis, a large fraction of the Dutch pension funds had to submit restoration plans for the recovery of their buffers. Such plans will have to rely primarily on a...

The present paper aims to quantify efficiency properties of real world social security systems of various institutional designs in order to identify an optimal pension design. Starting from a benchmark economy without social security, we introduce alternative pension systems and compare the...

We study the short-, medium-, and long-run implications of stimulating annuity markets in a dynamic general-equilibrium overlapping-generations model. We find that beneficial partial-equilibrium effects of stimulating annuity markets are counteracted by negative general-equilibrium...

We construct a dynamic stochastic general equilibrium model with overlapping generations in order to analyze the optimality of means-testing pension benefits in the UK. While previous studies only consider the long-run welfare effects of alternative policy reforms, we compute the full transition...

Using a model of a two-pillar pension system, designed after and calibrated to the Dutch situation, we explore for the funding ratio of pension funds and the welfare of individuals the implications of replacing nominal debt in the pension fund's portfolio with indexed debt. We consider...

We analyze the outcome of voting over the contribution to a pay-as-you-go (PAYG) pension system in the presence of financial and demographic shocks. The impact of shocks on pension contributions and benefits replicates major developments of pension systems around the world. A decrease in the...
