Finite Sample Performance of Semiparametric Estimation Methods for Partially Linear Models Under Nonparametric Endogeneity

In this paper we discuss the derivation, and use a Monte Carlo study to examine the finite sample performances of select estimators put forth in Martins-Filho et al. (2015) for partially linear semiparametric models under nonparametric endogeneity. We find that the selected estimators suciently account for the explicit nonparametric endogeneity of the underlying model in finite samples, and conclude that the proposed estimatorsˆm(x) and p are more ecient than their counterparts˜m(x) and wp. Our findings support the assertion that the estimators for m(x) are oracle ecient.
