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...

We use a reform of Sweden's sickness insurance system as a source of exogenous variation to analyse the presence of moral hazard. As a result of the reform, the replacement level was reduced from 90 percent of forgone earnings to 65 percent for the first three days; to 80 percent between day 4...

We propose a general test for exogeneity that is robust against distributional misspecification. The test can also be used to identify other types of misspecifications, such as the presence of a random coefficient. The idea is to sort the data with respect to a variable (a sorting score) and...

The treatment effect of a Swedish employment subsidy is estimated using exact covariate-matching and instrumental variables methods. Our estimates suggest that the programme had a positive treatment effect for the participants. <p> We also show how non-parametric methods can be used to estimate the...</p>

Using both register and survey data, two types of labour market training programs are compared. One program is part of the regular Swedish labour market training and the other, Swit, was initiated as an experiment during a two-year period, in an attempt to solve a bottleneck problem with people...

We analyze the effect of economic incentives on worker absenteeism, using panel data on work absence for 1990 and 1991 with a sample of 1,396 Swedish blue-collar workers. During this period Sweden implemented major reforms of both its national income replacement program for short-term sickness...

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)...

Using a unique micro panel data set we investigate whether active labor market programs improve employment prospects and increase mobility in the longer run. We consider two prototype programs: job creation programs and training programs. We find that both programs reduce the chances of finding...

This paper discusses the evaluation problem using observational data when the timing of treatment is an outcome of a stochastic process. We show that, without additional assumptions, it is not possible to estimate the average treatment effect and treatment on the treated. It is, however,...
