IZA is an independent nonprofit organization supported by Deutsche Post Foundation. The center is associated with the University of Bonn and offers a stimulating research environment through its international network, workshops and conferences, data service, project support, research visits and doctoral program. IZA engages in (i) original and internationally competitive research in all fields of labor economics, (ii) development of policy concepts, and (iii) dissemination of research results and concepts to the interested public.

We study the non-parametric identification of a mixed proportional hazard model with lagged duration dependence when data provide multiple outcomes per individual or stratum. We show that the information conveyed by the within strata variation can be exploited to nonparametrically identify lagged duration dependence in more general models than in the literature.JEL Classification: C14, C41

Times of change: what drives the growth of work arrangements in Germany?

“…The different types of temporary employment can be used as a recruiting device and may therefore increase the efficiency of matching labour supply and demand (Osterman and Burton 2005;Boockmann and Hagen 2008). Fourthly, nonstandard work arrangements offer more flexibility to adapt available personal resources to variations in product demand (Bentolila and Saint-Paul 1992;Nunziata and Staffolani 2007;Nienhüser 2008;Picchio 2012). And finally nonstandard work arrangements can be seen as a kind of buffer to protect core workers.…”

The effect of temporary in-work support on employment retention: Evidence from a field experiment

“…This does not help in the model considered in this paper, where we allow for lagged duration dependence across spells of the same type as well as across spells of different types. However, Picchio (2012) shows that, where a sufficient number of spells are observed, identification is achieved without the need for regressors or fixed baseline hazards. Since within our sample, 21 per cent of individuals are observed to have four or more spells (Table 4), we have grounds to view the conditions for the Picchio (2012) result to hold as being met.…”
