The issue considered in this study is whether objective, official reports on disability status are reliable. While there is a rather large literature on the reliability of self-reported disability, evidence regarding objective data is scant. It seems to be a widely held view among researchers...

The classical Roy-model of selection on the labor market is extended in order to analyze intergenerational mobility. This is done by linking ability uncertainty to family background. I derive implications for the allocation of talent and for background dependent earnings patterns within...

This paper applies a systems-oriented, “holistic” approach to China’s radical economic reforms during the last quarter of a century. It characterizes China’s economic reforms in terms of a multidimensional classification of economic systems. When looking at the economic consequences of...

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...

It is useful to distinguish between exogenous and endogenous factors behind contemporary and expected future problems for the welfare state. This paper tries to identify major problems of both types and to indicate alternative reform possibilities to deal with them. At the same time as several...

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...
