Nonparametric identification in nonseparable duration models with unobserved heterogeneity

Abstract

We study nonparametric identification of nonseparable duration models with unobserved heterogeneity. Our models are nonseparable in two ways. First, genuine duration dependence is allowed to depend on observed covariates. Second, observed and unobserved characteristics may interact in an arbitrary way. Our study develops novel identification strategies for a comprehensive account of typical duration model settings. In particular, we show identification in single-spell models with and without time-varying covariates, in multiple models with shared frailty and lagged duration dependence, in single-spell and multiple-spell competing risks models, and in treatment effects models where treatment is assigned during the individual spell in the state of interest.
