“...There are many environments in econometrics which require nonseparable modeling of a structural disturbance. In a nonseparable model with endogenous...”

“...We consider the problem of estimating the value ℓ(ϕ) of a linear functional, where the structural function ϕ models a nonparametric relationship in presence of...”

“...This article proposes a test for missing at random (MAR). The MAR assumption is shown to be testable given instrumental variables which are independent of...”

“...We consider the problem of regressions with selectively observed covariates in a nonparametric framework. Our approach relies on instrumental variables that...”

“...This paper provides a new methodology to analyze unobserved heterogeneity when observed characteristics are modeled nonlinearly. The proposed model builds on...”

“...We study a semi-/nonparametric regression model with a general form of nonclassical measurement error in the outcome variable. We show equivalence of this...”
