In their IZA Discussion Paper 10247, Johansson and Lee claim that the main result (Proposition 3) in Abbring and Van den Berg (2003b) does not hold. We show that their claim is incorrect. At a certain point within their line of reasoning, they make a rather basic error while transforming one...

It is said that knowing the right people is essential for one's career, which is supported in the literature on social capital. However, the empirical evidence in this field remains ambiguous, while the literature recognizes that "connections" certainly help finding any job at all, it remains...

This paper investigates the effect of locus of control (LOC) on the length of mothers’ employment break after childbirth. Using data from the German Socio-Economic Panel Study (SOEP), duration data reveals that women with an internal LOC return to employment more quickly than women with an...

Diese Dissertation befasst sich mit zwei Aspekten von freiwilligen Börsenrückzügen: Charakteristika von Unternehmen, welche die Börsennotierung aufgeben sowie dem Einfluss des Lebenszyklusabschnitts auf die Rückzugsentscheidung. Die erste Studie befasst sich mit Theorien zu freiwilligen...

We develop a nonparametric instrumental variable approach for the estimation of average treatment effects on hazard rates and conditional survival probabilities, without model structure. We derive constructive identification proofs for average treatment effects under noncompliance and dynamic...

This paper considers identification of treatment effects on conditional transition probabilities. We show that even under random assignment only the instantaneous average treatment effect is point identified. Because treated and control units drop out at different rates, randomization only...

The main purpose of this paper is to analyze the influence of previous experience and learning capabilities on survival in product and process innovation for Spanish manufacturing firms in the period 1990-2010. The authors find past and path dependence and confirm the important effect of R&D...
