TY - RPRT AU - Picchio, Matteo TI - Lagged Duration Dependence in Mixed Proportional Hazard Models PY - 2011/Oct/ PB - Institute of Labor Economics (IZA) CY - Bonn T2 - IZA Discussion Paper IS - 6089 UR - https://www.iza.org/publications/dp6089 AB - 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 non-parametrically identify lagged duration dependence in more general models than in the literature.
