Kinderlosigkeit hat zwei unmittelbare Auswirkungen auf das Rentensystem. Erstens stehen dadurch in der nächsten Generation weniger Beitragszahler zur Verfügung. Zweitens zahlen Kinderlose ihrerseits typischerweise mehr Rentenbeiträge. Denn insbesondere Frauen ohne Kinder haben ein meist...

Robert Fenge, Universität Rostock, weist in seinem Kommentar darauf hin, dass der rentensystematische Grundsatz – wer mehr einzahlt, bekommt auch mehr Rente heraus – mit den Vorschlägen für steuerfinanzierte oder beitragsfinanzierte Zusatzrenten aufgegeben würde. Seiner Ansicht nach ist...

This paper investigates the inter-temporal structure of implicit taxes that arise in unfunded pension schemes. We demonstrate that these tax rates are declining over the life cycle. Using German micro-data for men and married women we estimate periodic wage elasticities of labour supply in order...

This paper discusses the efficiency of a pay-as-you-go pension reform by introducing a child benefit in an endogenous fertility setting.

A key figure which can be applied to measuring inter-generational imbalances involved in existing public pension schemes is given by the "implicit tax" that is levied on each generation's life-time income through participation in these systems. The implicit tax arises from the fact that, quite...
