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.

We suggest a political economy explanation for the stylized fact that intragenerationally more redistributive social security systems are smaller. We relate the stylized fact to an efficiency-redistribution trade-off to be resolved by political process. The inefficiency of social security...

In several developed countries, the ageing process of the population may pose fiscal risks to the PAYG systems of public pensions. This paper studies the determinants of two forms of accessing retirement in Spain, either partial or full retirement. Our goal is to identify if social security...

The paper presents a non-exhaustive survey of the literature designed to explain emergence, size and political sustainability of pay-as-you-go pension systems. It proposes a simple framework of analysis (a small open two overlapping generation economy model), around which some variants are...

Options for reforming unfunded public pension schemes that are now being discussed all share the feature that the burden induced by demographic change would be shifted towards presently living and away from unborn generations. Existing models of the political economy of pension reform can not...

Immigration has been popularised in the economics literature as a tool to balance the troubled PAYG pension systems. A pivotal research by Razin and Sadka showed that unskilled immigration can surmount the pension problem and, further, boost the general welfare in the host economy. However a...

This paper discusses the efficiency of a pay-as-you-go pension reform by introducing a child benefit in an endogenous fertility setting. In the model of a small open economy, higher fertility is associated with a reduction of lifetime labor supply. The optimum share of fertility-related pensions...

We consider a political economy model in which agents have the possibility to hide part of their earnings in order to avoid taxation. Taxation is exclusively used to finance a pension system. If the pension system is implemented, agents in their old age receive a benefit which includes both a...
