Longevity, Life-Cycle Behavior and Pension Reform

How can public pension systems be reformed to ensure fiscal stability in the face of increasing life expectancy? To address this pressing open question in public finance, we estimate a life-cycle model in which the optimal employment, retirement and consumption decisions of forward-looking individuals depend, inter alia, on life expectancy and the design of the public pension system. We calculate that, ...

Profitability of Pension Contributions: Evidence from Real-Life Employment Biographies

Micro-econometric intra-cohort profitability analyses of pay-as-you-go (PAYG) pension contributions are rare. We use representative employment histories of a birth cohort of German PAYG pension insurants retiring in year 2005 to econometrically examine the determinants of the profitability of such contributions using nominal internal rates of return (IRR) as profitability measure. When future nominal ...

Armut in Deutschland: Bevölkerungsgruppen unterhalb der Alg II-Grenze

Einkommen und Armut von Familien und älteren Menschen

Die Einkommensposition von Familien hängt nicht nur von der Erwerbssituation der Haushaltsmitglieder ab, sondern auch vom Alter der Kinder. Dies zeigt eine Auswertung des vom DIW Berlin in Zusammenarbeit mit Infratest Sozialforschung erhobenen Sozio-oekonomischen Panels (SOEP). Zusammenlebende Paare mit Kindern kommen danach - gemessen an der gesamten Bevölkerung - auf ein durchschnittliches Einkommen. ...

Erwerbsminderung als Armutsrisiko

Schwere Erkrankungen stellen ein wesentliches Risiko für Einkommen und Vermögensbildung der Haushalte in Deutschland dar. Das Risiko krankheits-bedingter Erwerbsunfähigkeit soll zwar langfristig durch die Erwerbs-minderungsrente (EM-Rente) abgesichert werden. Die durchschnittlichen Nettozahlbeträge sind allerdings im Zeitraum zwischen 2000 und 2012 von 706 EUR auf gerade einmal 607 EUR gefallen. Dies ...

Health-Related Life Cycle Risks and Public Insurance

This paper proposes a dynamic life cycle model of health risks, employment, early retirement, and wealth accumulation in order to analyze the health-related risks of consumption and old age poverty. In particular, the model includes a health process, the interaction between health and employment risks, and an explicit modeling of the German public insurance schemes. I rely on a dynamic programming ...

Unemployment and Portfolio Choice: Does Persistence Matter?

We use a life-cycle model of consumption and portfolio choice to study the effects of social security on the investment decisions of households for the European case. Our model is mainly based on the one developed by Cocco, Gomes, and Maenhout (2005). We extend it by unemployment risk using Markov chains to model the transition between different employment states. In contrast to most models in the ...

Unemployment and Portfolio Choice: Does Persistence Matter?

Households can rely on private savings or on public unemployment insurance to hedge against the risk of becoming unemployed. These hedging mechanisms are used differently across countries. In this paper, we use a life cycle model to study the effects of unemployment on the portfolio choice of households in the US and in Germany. We distinguish short- and long-term unemployment and find that, in case ...
