On Nonparametric Identification of Treatment Effects in Duration Models

Johansson, Per; Lee, Myoung-jae - 2016

We show that the main nonparametric identification finding of Abbring and Van den Berg (2003b, Econometrica) for the effect of a timing-chosen treatment on an event duration of interest does not hold. The main problem is that the identification is based on the competing-risks identification...

Geoadditive hazard regression for interval censored survival times

Kneib, Thomas - 2005

The Cox proportional hazards model is the most commonly used method when analyzing the impact of covariates on continuous survival times. In its classical form, the Cox model was introduced in the setting of right-censored observations. However, in practice other sampling schemes are frequently...
