Based on Norwegian register data we show that having a lone parent in the terminal phase of life significantly affects the offspring's labor market activity. The employment propensity declines by around 1 percentage point among sons and 2 percentage points among daughters during the years just...

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...

Does an income tax harm economic efficiency more the more progressive it is? Public economics provides a strong case for a definite ‘yes’. But at least three forces may pull in the other direction. First, low-wage workers may on average have more elastic labour supply schedules than...

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...

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...
