This article, based on two books (2008, forthcoming), sets out principles for pension design: pension systems have multiple objectives, analysis should consider the pension system as a whole, analysis should be in a second-best context, different systems share risks differently and have...

We model the optimal reaction of a public PAYG pension system to demographic shocks. We compare the ex-ante first best and second best solution of a Ramsey planner with full commitment to the outcome under simple third best rules that mimic the pension systems observed in the real world. The...

Conventional pension systems suffer from a design defect which makes them financially unsustainable, and a source of inefficiency for the economy as a whole. The paper outlines a second-best policy which includes a public pension system made up of two parallel schemes, a Bismarckian one allowing...

Public pay-as-you-go pensions still form the dominant pillar of old-age provision in Germany. This is in marked contrast to the situation in Anglo-Saxon countries. It has advantages if labour markets are strong, e.g., following a quick recovery from the Great Recession. It has disadvantages, as...

Within a politico-economic model we first establish three hypotheses: (i) Retirees generally prefer a higher retirement age than workers, whereby just retired individuals prefer the highest retirement age, (ii) in equilibrium the level of the legal retirement age is increasing in longevity and...

Over the next four decades, increasing old-age dependency ratios exert an enormous upward pressure on welfare spending in most developed countries. As this is mainly due to existing unfunded public pension schemes, many countries have embarked on far-reaching reforms in this area, strengthening...

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 studies the impact of recent changes in second pension pillars of three Central and Eastern European Countries. The paper seeks to answer the following questions: i) what is the impact on the sustainability of Poland's pension system of the decrease in the pension contribution going...

The Croatian system of old-age provision comprises a traditional public pay-as-you-go scheme and a mandatory funded scheme ("second pillar") that will provide increasing amounts of supplementary pensions to those entering retirement in the future. Due to the continuing economic crisis, the...

A reform of a pay-as-you-go social security makes the pensioners worse off and the working generations better off in the period of the reform (in a dynamically efficient economy without altruism). The observed reluctance across all age groups to support such reforms is usually explained by the...
