On Welfare Effects of Increasing Retirement Age

By Krzysztof Makarski (National Bank of Poland; Warsaw School of Economics (SGH)) & Joanna Tyrowicz (National Bank of Poland; University of Warsaw) We develop an OLG model with realistic assumptions about longevity to analyze the welfare effects of raising the retirement age. We look at a scenario where an economy has a pay-as-you-go defined benefit scheme and compare it to a scenario with defined contribution schemes (funded or notional). We show that, initially, in both types of pension system schemes...

The Optimal Allocation of Longevity Risk with Perfect Insurance Markets

By Antoine Bommier (ETH Zürich) & Hélène Schernberg (ETH Zurich) This paper discusses the allocation of aggregate longevity risk in the case of perfect insurance markets. We show that the optimal allocation transfers some risk to the pensioners, even if pension providers have access to a perfect insurance market. Individuals prefer contributions and benefits to depend on the evolution of aggregate mortality rates rather than being fixed. Indeed, this flexibility offers an interesting diversification strategy where the prospect of a...

In order to address the various issues, these new product forms should reduce...

The Rising Longevity Gap by Lifetime Earnings – Distributional Implications for the Pension System

By Peter Haan (DIW Berlin), Daniel Kemptner (DIW Berlin), Holger Lüthen (DIW Berlin) This study uses German social security records to provide novel evidence about the heterogeneity in life expectancy by lifetime earnings and, additionally, documents the distributional implications of this earnings-related heterogeneity. We find a strong association between lifetime earnings and life expectancy at age 65 and show that the longevity gap is increasing across cohorts. For West German men born 1926-28, the longevity gap between top and bottom...
