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 face the problem of how to reform social security systems to cope with increasing life expectancy. This raises questions concerning both distribution and risk sharing across generations. These issues are addressed within an OLG model with stochastic life expectancy across...

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...

Increasing longevity causes an upward trend in the dependency ratio in many countries. This raises concerns about the financial sustainability of social security schemes, and reform initiatives and proposals abound. It is shown that a fundamental policy choice inevitably arises since a given...

The consequences of cylical contingencies in unemployment insurance systems are considered in a search-matching model allowing for shifts between "good" and "bad" states of nature. An argument for state contingencies is that insurance arguments are stronger and incentive effects weaker in bad...

Workfare policies are often introduced in labour market policies to improve the trade-off between incentives and insurance as an alternative to benefit reductions. Most of the debate on such policies has focussed on the direct effect of those participating in the scheme, and in particular the...

The consequences of business cycle contingencies in unemployment insurance systems are considered in a search-matching model allowing for shifts between good and bad states of nature. We show that not only is there an insurance argument for such contingencies, but there may also be an incentive...
