This supplement follows the paper entitled "Efficient Semiparametric Estimation of Quantile Treatment Effects". We present here (i) detailed results from an empirical example, (ii) results of a Monte Carlo exercise, (iii) details of the variance estimation, and (iv) proofs of the theoretical results.
This Supplementary Material contains some of the more technical details omitted from the paper ?Instrumental Variable Estimation of Nonlinear Errors-in-Variables Models?. First, a brief review of the Theory of Generalized Functions is presented. Second, proofs regarding some basic properties of Fourier transforms as well as the asymptotics of the proposed GMMestimator are given. Third, the proposed estimator is compared with the one suggested in Hausman, Newey, Ichimura, Powell (1991). Fourth, an alternative derivation of the moment conditions necessitating weaker regularity conditions is provided. Fifth, the details of the Monte Carlo simulations are described. Sixth, an application of the proposed methodology to the estimation of the black-white income gap is presented. Finally, some computational aspects of the implementation of the estimator are described.
In this appendix we provide the complete theoretical analysis of Section 5. The propositions in the main part of the paper follow immediately from the propositions proved here. We also provide some additional experimental data at the end of the appendix.
This file contains the complete instructions of the Bonus-Incentive Treatment (sessions S3 and S4) translated from German to English. The instructions of the Trust-Incentive Treatment (S1 and S2) and the Control Treatment (S5 and S6) are structured similarly and are not reported here for space reasons, but they and all the original instructions in German are available from the authors upon request.
