Consider a setting where a treatment that starts at some point during a spell (e.g. in unemployment) may impact on the hazard rate of the spell duration, and where the impact may be heterogeneous across subjects. We provide Monte Carlo evidence on the feasibility of estimating the distribution...

The application of continuous time Weibull models on discrete unemployment duration data may produce bias in the estimated shape of the hazard rate. The bias can be substantial even for weekly duration data, and it is seriously aggravated if the Weibull model is erroneously mixed with a Gamma...

We investigate how transitions from unemployment are affected by economic incentives and spell duration. Based on unique Norwegian register data that exhibit the rarity of random-assignment-like variation in economic incentives, the causal parameters are identified without reliance on...
