Abstract

This note shows the equivalence of different instrumental variables estimators to solve the endogeneity problem in linear models when valid instruments are available. We demonstrate that the exclusion restriction estimator proposed by Chernozhukov and Hansen (2006) is equivalent to the two-stage least squares and the control function estimators for linear models.
