Joint Estimation and Bandwidth Selection in Partially Parametric Models
Journal of Applied Econometrics, Volume 41, Issue 3, Page 227-239, April/May 2026.ABSTRACT We propose a single‐step approach to estimating a model with both a known nonlinear parametric component and an unknown nonparametric component. We study the large sample behavior of a simultaneous optimization routine that estimates both the parameter vector of the parametric component and the bandwidth vector used to smooth the unknown ...
