Using three major UK pension reforms as natural experiments we investigate the relationship between pension saving and discretionary private savings. Unlike most differences-in -differences approaches which rely on average differences between the control and the treatment group, we use economic...

We examine how labor immigration affects public pensions under centralized wage setting. We show that immigration improves the sustainability of pay-as-you-go pensions if and only if total employment declines. This occurs if the labor demand elasticity exceeds the unemployment rate.

Although immigration of workers generates a positive externality on members of domestic pension systems, many countries are very reluctant to allow foreigners into their labor markets. In a political economic framework, we explain this voting outcome by considering a young unskilled median voter...

The paper surveys the state of German pension system after a sequence of reforms aimed at achieving long-term sustainability. We argue that the latest reforms have moved pension provision in Germany in principle from a defined benefit to a defined contribution scheme, and that this move has...

This paper analyzes pension reforms in Europe and their determinants. As pension reforms are intrinsically difficult to define and pinpoint, we introduce an alternative measure of pension reforms by comparing long-term forecasts of pension expenditures for seventeen European countries. The...

This paper considers the possibility of letting a pay-go pension system mimic a fully funded pension system. Generically, it turns out to be impossible to make a less than fully funded pension system actuarially fair on average. But a non-funded pay-go pension system can provide an actuarially...

This paper presents a unified analytical framework for the analysis of social security reform. It discusses reform along two dimensions: Pay-As-You-Go versus fully funded on the one hand, and actuarial versus non-actuarial on the other. Making the system more actuarial entails a trade-off...

The paper discusses the consequences for the functioning of different pension systems of various types of socioeconomic changes, mainly demographic developments, variations in productivity growth and changes in real interest rates. Two of the pension systems have exogenous and four have...
