In the Netherlands, students who want to become a medical specialist have toenrol in a training program which is in limited supply. During the search for aposition as trainee (or "junior medical specialist"), they may accept atemporary job as a medical assistant. We use a micro data set to...

Social surveys are often used to estimate unemployment duration distributions. Survey non-response may then cause a bias. We study this by using a data set that combines survey information of individual workers with administrative records of the same workers. The latter provide information on...

Causal effects of a policy change on hazard rates of a duration outcome variable are not identified from a comparison of spells before and after the policy change, if there is unobserved heterogeneity in the effects and no model structure is imposed. We develop a discontinuity approach that...

Previous work on moral-hazard problems has shown that, under certain conditions, bonus contracts create optimal individual incentives for risk-neutral workers. In our paper we demonstrate that, if a firm employs at least two workers, it may further bene.t from combining worker compensation via a...

In 2005, the unemployment compensation for long-term unemployed was reduced in Germany. We examine how this reform affected the transition probability to employment. Additionally, we inspect how this effect varies over unemployment duration. We estimate proportional hazard models using German...

This paper puts focus on the hazard function of inter-trade durations to characterize the intraday trading process. It sheds light on the time varying trade intensity and, thus, on the liquidity of an asset and the informations channels which propagate price signals among asymmetrically informed...

We develop a nonparametric instrumental variable approach for the estimation of average treatment effects on hazard rates and conditional survival probabilities, without model structure. We derive constructive identification proofs for average treatment effects under noncompliance and dynamic...

Shared-frailty survival models specify that systematic unobserved determinants of duration outcomes are identical within groups of individuals. We consider random-effects likelihood-based statistical inference if the duration data are subject to left-truncation. Such inference with...

In 2005, the unemployment benefits for long-term unemployed were reduced in Germany. We investigate the effect of this reform on the transition probability from unemployment to employment using a large German administrative spell data set (SIAB 1975 - 2010). We estimate that the daily transition...

Causal effects of a policy change on hazard rates of a duration outcome variable are not identified from a comparison of spells before and after the policy change, if there is unobserved heterogeneity in the effects and no model structure is imposed. We develop a discontinuity approach that...
