In this paper we analyse several measures which are typically included in a social security reform: a cut in the social security benefits, an increase in the social security tax and tax incentives for the purchase of private life annuities, which have recently become quite popular at the...

Die Riester-Rente beziehungsweise die einzelnen Riester-Produkte haben sich seit ihrer Einführung zuungunsten von Sparern verändert. Verträge, die heute abgeschlossen werden, führen oftmals zu einer geringeren Rendite als 2001 vereinbarte Verträge. Insgesamt sind die Renditen aus...

Nonfinancial defined contribution (NDC) pension systems have recently become popular because they provide the strong incentives of the private funded systems without requiring a difficult transition period. Using the framework of mechanism design, these systems have theoretically been criticized...

The dependence of benefit on the retirement age (the schedule) is an important feature in any public pension system. The nonfinancial defined contribution (NDC) pension system has recently become popular mainly because of its allegedly actuarial fairness. Using the framework of mechanism design...

The traditional approach to flexible retirement (e.g. NDC) neglects the impact of asymmetric information on actuarial fairness (neutrality). The mechanism design approach (e.g. Diamond, 2003) gives up the requirement of neutrality and looks for a redistributive second-best benefit-retirement-age...
