How do we explain the poor employment performance in Western Europe since about the mid-1970s? This question is in fact twofold: what initiated the dramatic rise in unemployment, and what mechanisms have made it continue for so long? My attempts to answer these questions form the basis for a...

In an analysis of the risk-sharing properties of different types of pension systems, we show that only a fixed-fee pay-as-you-go (PAYG) pension systems can provide intergenerational risk sharing for living individuals. Under some circumstances, however, other PAYG pension systems can enhance the...

A rationale for a compulsory pension system is that the government wants to correct supposedly myopic behavior by the individuals. Given the existence of such a system, we calculate the optimal relation between marginal contributions and benefits, i.e., the optimal degree of marginal actuarial...

We analyze motivations for, and possible alternatives to, the Stability and Growth Pact (SGP). With regard to the former, we identify domestic policy failures and various cross-country spillover effects; with regard to the latter, we contrast an "economic-theory" perspective on optimal...

The modern welfare state and full-employment policies have common intellectual roots. In the 1930s and 1940s, Keynesian visions of full employment and Beveridge-inspired ideas of a universal welfare state grew up in about the same intellectual environment. Both ideas emphasized a government’s...

New informationa and communication technology (ICT) makes consumers better informed about available products, product quality and prices, which mitigates problems of assymetry of information. The entry of firms is facilitated, competition and economic efficiency is boosted and the market powers...

We develop a simple yet realistic model of income insurance, where the individual’s ability and willingness to work is treated as a continuous variable. In this framework, income insurance not only provides income smoothing, it also relieves the individual from particularly burdensome work. As...

Structural unemployment differs from cyclical unemployment by not disappearing in cyclical booms. In economic theory, structural unemployment is usually analysed in terms of the concept of equilibrium unemployment (the "natural unemployment rate" in Friedman’s terminology). Two elaborate...

The expansion of welfare-state arrangements is seen as the result of dynamic interaction between market behaviour and political behaviour, often with considerable time lags, sometimes generating either virtuous or vicious circles. Such interaction may also involve induced (endogenous) changes in...

We analyze the consequences for sickness absence of a selective softening of job security legislation for small firms in Sweden in 2001. According to our differences-in-difference estimates, aggregate absence in these firms fell by 0.2-0.3 days per year. This aggregate net figure hides important...
