in being able to account for time-invariant, unobserved heterogeneity. 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 …
