The question of how governments should choose the frequency of payments has received little attention in the literature on the optimal design of public benefits programs. We propose a simple model in which the government chooses the length of the interval between payments, subject to a tradeoff...

In earlier literature, the suggested Pareto improvements in pay-as-you-go (PAYG) systems have relied on the presence of externalities or the possibility of intragenerational redistribution. We show that neither assumption is necessary in an economy with intergenerational trade in a fixed factor...

Certain federal, state, and local government employees do not pay into the Social Security system, but rather pay into alternative government pension plans. For purposes of the Social Security Act, where a worker pays into an alternative government pension plan, the worker’s employment...

We investigate the welfare effects of environmental tax reform, i.e. raising environmental taxes and using the proceeds to reduce distortionary taxes on labour. The framework of analysis is a small open economy with involuntary unemployment due to a rigid consumer wage. Environmental tax reform...

This paper provides the first estimate of the actuarial balance of the Spanish contributory pension system for the old age contingency, based on official data. The novel entry in the balance sheet, named "Contribution Asset" or "Hidden Asset", is at the centre of the theoretical discussion. A...

Die Rentenreformen zu Beginn dieses Jahrhunderts hinterlassen zunehmend Spuren. Das Rentenniveau sinkt kräftig. Gegenüber 1989 ergibt sich bereits heute eine Senkung um knapp 14 Prozent. Vorgesehen sind weitere Absenkungen mit der Folge einer drohenden Altersarmut insbesondere für...

The pension reforms of the beginning of this century left their marks. The pension level has dropped sharply. Compared with 1989 results suggest a reduction of almost 14 percent nowadays. Further reductions are announced with the consequence of threatening old age poverty particularly for low...

This paper compares the properties of funded and pay as go pension systems. When the population is aging pay as you go systems can´t sustain a pension system. However, if taxes are used to finance part of the pensions, the pay as you go system is better in all the relevant aspects. A system...
