When treatment effects of active labour market programmes are heterogeneous in anobservable way across the population, the allocation of the unemployed into differentprogrammes becomes a particularly important issue. In this paper, we present a statisticalmodel designed to improve the present...

In this paper we estimate the causal effect of lowering the public income transfers administered to newly arrived refugee immigrants in Denmark - the so-called starthelp - using a competing risk mixed proportional hazard framework. The two competing risks are exit to job and exit out of the...

This paper tests the signalling hypothesis using detailed flow-based employer-employee data from Denmark. The primary focus is to explore how the conditions in the pre-displacement firm affect the duration of unemployment. The empirical analysis is conducted within a competing risk framework,...

This paper investigates whether the stepping-stone effect of temporary agency employment varies over the business cycle. Using German administrative data for the period 1985-2012 and an estimation framework based on the timing-of-events model, we estimate in-treatment and post-treatment effects...

Using data from a large-scale randomized controlled trial conducted in Danish job centers, this paper investigates the effects of an intensification of mandatory return-to-work activities on the subsequent labor market outcomes for sick-listed workers. Using variations in local treatment...

We analyze the effect of substituting a weekly mathematics lessons in primary school grades 1-3 with a lesson in mathematics based on chess instruction. We use data from the City of Aarhus in Denmark, combining test score data with a comprehensive data base from administrative register. We use a...

This paper compares the effectiveness of public and private providers of employment services. Reporting from a randomized field experiment conducted in Denmark we assess empirically the case for contracting out employment services for a well-defined group of highly educated job-seekers...

We consider the consequences of working part-time on supplementary unemployment insurance benefits in the Danish labour market. Following the timing-of-events approach we estimate causal effects of subsidized part-time work on the hazard rate out of unemployment insurance benefit receipt. We...

Many targeted childhood interventions such as the Perry Preschool Project select eligible children based on a risk score. The variables entering the risk score and their corresponding weights are usually chosen ad hoc and are unlikely to be optimal. This paper develops a simple economic model...

Randomized experiments provide policy relevant treatment effects if there are no spillovers between participants and nonparticipants. We show that this assumption is violated for a Danish activation program for unemployed workers. Using a difference-in-difference model we show that the...
