We consider the problem of assessing the effects of a treatment on duration outcomes using data from a randomized … duration outcome, and noncompliance with the assigned treatment. Ignoring any of these issues could yield biased estimates of … duration. Our estimated bounds suggest that JC participation may increase the average duration of the last complete employment …

We find that duration dependence has an inverted U …-shape with exit rates initially increasing (indicating positive duration dependence) and then falling. Like previous researchers …, we find results consistent with negative duration dependence in models which ignore unobserved heterogeneity. Exit rates …
