Implementing a fairness component into a standard overlapping-generations model and allowing young individuals to vote on their own pension payments, we show that they adapt the pay-as-you-go pension scheme to future demographic changes. In particular, we explain why young generations cut their...

In this paper we analyze exemplarily the volatility of the internal rates of return of the German pension system over the life-cycle of an individual born in 1957. The outcome is compared to an alternative defined-contribution or defined-benefit policy. Based on the actual data, our resultsshow...

The authors outline a public pension reform where contribution rates are reduced to zero over a very long horizon and in a Pareto-improving fashion.

The paper evaluates the theoretical literature on public pension schemes. First, the terms pay-as-you-go and capital reserve are made precise. These two systems are then compared, followed by a consideration of their efficiency properties. Thereafter conversion policies are discussed.

The article reports research results on funded and unfunded pension schemes in an easily accessible form.

The article demonstrates that it is possible to convert a pay-as-you-go pension scheme into a capital reserve pension scheme in a Pareto-improving fashion and in finite time.

In der Arbeit wird mit Hilfe eines ökonometrischen Modells untersucht, welche Auswirkungen eine unterschiedliche Finanzierung der Sozialversicherung auf Aufbringung von Mitteln, Staatshaushalt, Wirtschaftswachstum und Beschäftigung hat.

The article investigates whether compulsory old age provisions are justified from an economic point of view. According to a standard argument, some people would not provide sufficiently for their old age in the absence of a compulsory pension system – they would become a charge to the public....

During the 1990s, some important European countries, particularly Italy and Sweden, have radically transformed their public pension system by adopting defined-contribution rules while retaining a pay-as-you-go financial architecture. This paper inquires into the theoretical properties of these...

Poland faces one of the most rapidly ageing population in Europe. The old age dependency ratio is expected to triple until 2060. Against this background, our paper examines the sustainability of Polish public finances and its isolated subsystems. We consider the profound recent reforms including...
