Identification in nonseparable models

Journal article

Weak nonparametric restrictions are developed, sufficient to identify the values of derivatives of structural functions in which latent random variables are nonseparable.

Estimating panel data duration models with censored data

Working Paper

This paper presents a method for estimating a class of panel data duration models, under which an unknown transformation of the duration variable is linearly related to the observed explanatory variables and the unobserved heterogeneity (or frailty) with completely known error distributions.

Confidence intervals for partially identified parameters

Working Paper

In the last decade a growing body of research has studied inference on partially identified parameters (e.g., Manski, 1990, 2003). Here the authors introduce conceptually different interval estimates that asymptotically cover each element in the identification region with fixed probability (but not necessarily every element simultaneously).

Another look at the regression discontinuity design

Working Paper

In this paper we show that the sharp RDD straightforwardly generalizes to the instances in which the eligibility for the program is established with respect to an observable pre-program measure with eligible individuals self-selecting into the treatment group according to an unknown process.
