The paper aims to assess tax-favored retirement accounts in a general-equilibrium overlapping-generations economy with idiosyncratic income risk and borrowing constraints. Our simulations indicate that tax-favored retirement accounts as implemented in many OECD countries will have a significant...

The present paper simulates the privatization of social security in an economy populated by overlapping generations of individuals that have time-consistent or time-inconsistent preferences, face mortality and individual income risk as well as borrowing constraints. We compute the transition...

This paper aims to quantify the welfare effects of progressive pension arrangements in Germany. Starting from a purely contribution-related benefit system, we introduce basic allowances for contributions and a flat benefit fraction. Since our overlapping-generations model takes into account...

The present paper studies the role of social security in an economy populated by overlapping generations of individuals that have time-consistent or time-inconsistent preferences, face mortality and individual income risk, borrowing constraints as well as progressive income taxes. Our...

The present paper aims to quantify the macroeconomic and welfare effects of taxfavored retirement accounts. Starting from an equilibrium without saving incentives, we introduce such accounts and compute the new transition path and the resulting long-run equilibrium. Since our...

The present paper clarifies the intergenerational welfare effects of life annuities. While present young cohorts experience significant welfare gains, future generations are hurt by lower bequest. For sufficiently high interest rates long-run welfare will decrease although aggregate efficiency...
