Following an era of a development towards earlier retirement, there has been a reversed trend to later exit from the labor market in Sweden since the late 1990s. We investigate whether or not there are potentials, with respect to health and work capacity of the population, for extending this...

We show that the main nonparametric identification finding of Abbring and Van den Berg (2003b, Econometrica) for the effect of a timing-chosen treatment on an event duration of interest does not hold. The main problem is that the identification is based on the competing-risks identification...

The effect of economic incentives on worker absenteeism is analyzed using panel data on work absence behavior for each day during 1990 and 1991 (i.e., 730 observations in the time dimension) for a representative sample of 1,396 Swedish blue collar workers. During the observed time period, a...

The incidence and duration of work absence spells for a sample of Swedish blue collar workers in 1991 are analyzed using the Kaplan-Meier estimator, discrete time hazard regression as well as stratified Cox regression. The main interest is directed towards the effect of economic incentives. The...

We show that in sorting cross-sectional data, the endogeneity of a variable may be successfully detected by graphically examining the cumulative sum of the recursive residuals. An interesting case arises with a continuous or ordered (e.g., years of schooling) endogenous variable. Then, a...

We introduce a framework to test for the exogeneity of a variable in a regression based on cross-sectional data. By sorting data with respect to a function (sorting score) of known exogenous variables, it is possible to utilize a battery of tools originally developed to detect model...

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...

Under the assumption of a single-index model the weighted average density derivative (WAD) estimator, estimates regression parameters up to scale. The small sample performance of ratio estimators are studied. For spherical errors in a latent variable specification the WAD estimator, in terms of...

This paper studies the consequences of screening and monitoring in the Swedish sickness insurance program on labor market and health outcomes. We exploit the fact that individuals are randomly assigned to offices with different levels of stringency regarding benefits. We find that the denial of...
