In this paper we examine whether the prospect of compulsory programme participation motivates individuals to leave the unemployment insurance (UI) system prior to participation. We analyze data from the Danish labour market. Here a series of reforms have enforced program participation and...

This study measures the effect of case management interview (CMI) on 1,000 long-term sick-listed employees’ probability of returning to work. In contrast to previous studies, we use instrumental variables to correct for selection effects in CMI. Using a competing hazard rate model, we find...

Competing risks models are fundamentally unidentified. This paper derives bounds for aspects of the underlying distributions under a number of different assumptions. These bounds are then applied to mortality data from the US. We find that trends in cancer show much larger improvements than was...

We combine two techniques to consistently estimate the effect of active labour market programmes and, in particular, active labour market policy regimes. Our aim is to explicitly estimate the threat effect of active labour market programmes. Based on Danish data (1998-2002) from administrative...

In this paper we compare the traditional econometric fixed effect/first difference estimator with the maximum likelihood estimator implied by covariance structure models for panel data. Our findings are that the maximum likelihood estimator is remarkable robust to mis-specifications, however in...

Dispersion in labor and factor productivity across firms is large and persistent, large flows of workers move across firms, and worker reallocation is an important source of productivity growth. The purpose of the paper is to provide a formal explanation for these observations that clarifies the...

Previous work on board size effects in closely held corporations has established a negative correlation between board size and firm performance. We argue that this work has been incomplete in analysing the causal relationship due to lack of ownership information and weak identification...

We employ a regression-discontinuity design to identify effects on educational attainment (years of education) of class size and the number of pupils per weekly teacher hour using administrative rules as instruments. We use a Danish administrative panel data set based on a 10% random sample of...

This paper introduces a dynamic panel data model where the regression coefficients are allowed to vary across cross-section units. The framework is a mixture model obtained by mixing two dynamic panel data models with different parameters according to some mixing weights. The parameters in the...
