We estimate a labor supply model on a random sample of Swedish male and female blue collar workers to study the effect of economic incentives on work absence behavior. We observe work absence for each day during 1990 and 1991 for each worker in the sample. We use non-parametric (Kaplan-Meier)...

This study tests for forward-looking moral hazard in the social insurance system by exploiting a 1991 reform in Sweden. The replacement rate was reduced for short absences but not for long absences, which introduced a potential future cost of returning to work. Using this exogenous variation in...

The Knappschaft underlies Bismarck's sickness and accident insurance legislation (1883 and 1884), which in turn forms the basis of the German social-insurance system today and, indirectly, many social-insurance systems around the world. The Knappschaften were formed in the medieval period to...

Previous research suggests that there are substantial interactions between the unemployment insurance (UI) and the sickness insurance (SI) in Sweden. Moral hazard arises in the interplay between these two social insurance systems, since by reporting sick an unemployed person can postpone the UI...

This paper studies moral hazard in a sickness-insurance fund that provided the model for socialinsurance schemes around the world. The German Knappschaften were formed in the medieval period to provide sickness, accident, and death benefits for miners. By the mid-nineteenth century,...

This paper looks at a specific type of moral hazard that arises in the interplay between two large public insurance systems in Sweden, namely the sickness insurance (SI) and the unemployment insurance (UI). Moral hazard can arise from the benefit size structure as for some unemployed persons,...

The paper discusses harmonization of unemployment insurance (UI) and sickness insurance (SI). The focus is on the difference between the benefit ceilings in the two insurance systems that has been shown to affect the behavior among unemployed SI recipients. The four conclusions are: (i) It is...

This paper examines the incentive effects caused by the interactions between unemployment insurance (UI) and sickness insurance (SI), two important components of Sweden's social insurance system. There are two main topics of interest: how the sickness report rate and the length of the subsequent...
