Within the frame of the Nordic welfare model, pension system design has taken very different routes. While the overall aims in terms of distribution and replacement rates are similar, the division of labour between defined benefit and contribution as well as pay-as-you-go versus funded schemes...

This paper revisits the role played by myopia in generating a theoretical rationale for pay-as-you-go social security in dynamically efficient economies. Contrary to received wisdom, if the real interest rate is exogenously fixed, enough myopia may justify public pensions but never alongside...

Many countries, in an effort to address the problem that too many retirees have too little saved up, impose mandatory contributions into retirement accounts, that too, in an age-independent manner. This is puzzling because such funded pension schemes effectively mandate the young, who wish to...

In the real world, public pay-as-you-go pension (PAYG) schemes are popular and co-exist with private, retirement-saving schemes. This is true even in dynamically efficient economies where such pensions offer a lower return. The classic Aaron-Samuelson result argues that, in theory, this is...

Socio-economic differences in longevity have fuelled a debate whether pension systems have a regressive bias favouring groups with a high life expectancy. We show that the distributional implications of such pooling depend critically on the benefit profile across age/time, which in turn is...
