Bootstrap Inference In A Linear Equation Estimated By Instrumental Variables

No 1024, Working Paper from Economics Department, Queen's University

Abstract: We study several tests for the coefficient of the single right-hand-side endogenous variable in a linear equation estimated by instrumental variables. We show that all the test statistics--Student's t,Anderson-Rubin, Kleibergen's K, and likelihood ratio (LR)--can bewritten as functions of six random quantities. This leads to a number ofinteresting results about the properties of the tests under weak-instrumentasymptotics. We then propose several new procedures for bootstrapping the threenon-exact test statistics and a conditional version of the LR test. These use more efficient estimates of the parameters of the reduced-form equation than existing procedures. When the best of these new procedures is used, K and conditional LR have excellent performance under the null, and LR also performs very well. However, power considerations suggest that the conditional LR test, bootstrapped using this new procedure when the sample size is not large, is probably the method of choice.
