We study the sustainability of pension systems using a life-cycle model with distortionary taxation that sets an upper limit to the real value of tax revenues. This limit implies an endogenous threshold dependency ratio, i.e. a point in the cross-section distribution of the population beyond...

We discuss public pension systems in a multi-period overlapping generations model with gerontologically founded human aging and a special focus on occupation-specific morbidity and mortality. We examine how distinct replacement rates for white-collar and blue-collar workers and early retirement...

We study numerically the inter- and intra-generational welfare consequences of alternative pension fund policies in response to unexpected demographic, financial and macro-economic shocks. Our analysis is based on an applied many-generation OLG model describing a small-open economy with...

In the context of the aging population and with the Portuguese public social security system reaching maturity, pension expenditures recorded a marked upwards trend in the last decade, jeopardizing the system's long-term viability. This paper illustrates how the recent reforms in the social...

We compare two policies of increasing British state pension provision: (a) increase the pensionable age of men and women, (b) maintain the existing retirement age but require older workers to work longer per-period hours. There are reasons for policy makers to give serious consideration to the...

Die Bundestagswahl 2017 wirft ihre Schatten voraus. Das kommt auch in den unterschiedlichen Argumenten zur gesetzlichen Rentenversicherung zum Ausdruck, die die Vertreter der verschiedenen Parteien und Interessengruppen derzeit in den Medien vortragen. Jochen Pimpertz hat drei aktuelle Fragen...

We set up an overlapping generations model with endogenous fertility to study pensions policies in an ageing economy. We show that an increasing life expectancy may not be detrimental for the economy or the pension system itself. On the other hand, conventional policy measures, such as...

Durch die steigende Lebenserwartung wird sich die Rentenbezugsdauer und damit die Anzahl der jährlich zu versorgenden Ruheständler in der Gesetzlichen Rentenversicherung (GRV) erhö-hen. Zudem beschleunigt die alternde Babyboomer-Generation schon in den nächsten Jahren den Anstieg der...
