Does the average level of sickness absence in a neighborhood affect individual sickness absence through social interaction on the neighborhood level? To answer this question, we consider evidence of local benefit-dependency cultures. Well-known methodological problems in this type of analysis...

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 characterize pension systems along three dimensions: 1) actuarial vs. non-actuarial, 2) funded vs. pay-as-you-go, 3) defined-contribution vs. defined-benefit. Increasing the degree of actuarial fairness, by strengthening the linkage between contributions and benefits, reduces labor market...

Children who can count on support from altruistic parents may not try hard to succeed in the labor market. Moreover, parental altruism makes withdrawal of such support non-credible. To promote work effort, parents may want to instill norms which later cause their children to experience guilt or...

This paper presents a new approach to the theory of the firm by identifying factor complementarities as central to the determination of the firm's boundaries. The factor complementarities may take a variety of forms: technological and informational complementarities, as well as economies of...

A large literature on ex ante moral hazard in income insurance emphasizes that the individual can affect the probability of an income loss by choice of lifestyle and hence, the degree of risk-taking. The much smaller literature on moral hazard ex post mainly analyzes how a “moral hazard...

Sweden experienced exeptionally fast economic growth during the century-long period 1870-1970. This illustrates that a decentralized market economy, highly open to international transactions, may be quite conductive to sustained productivity growth if the government fulfills its "classical"...

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

The paper shows how prolonged price inertia can arise in a macroeconomic system in which there are temporary price rigidities as well as production lags in the use of intermediate goods. In this context, changes in production demand - generated, say, by changes in the money supply - have...

This paper deals with economic incentives and welfare-state arrangements in OECD countries. This paper emphasises what may be called "dynamic" incentive issues, i.e. incentive effects that envolve over time. The discussion also covers the interplay between incentives and social norms among...
