More on 2SLS We can estimate y 2* by regressing y 2 on z 1, z 2 and z 3 – the first stage regression If then substitute ˜ 2 for y 2 in the structural model, get same coefficient as IV While the coefficients are the same, the standard errors from doing 2SLS by

2SLS is also called IV estimator. b 1 is over-identified if there are multiple IVs. b 1 is under-identified if there is no excluded exogenous variable. For instance, we have over-identification if we know the number of raining days and the number of snowy days. If 5

ivreg: Two-Stage Least-Squares Regression with …

Overview. The ivreg package provides a comprehensive implementation of instrumental variables regression using two-stage least-squares (2SLS) estimation. The standard regression functionality (parameter estimation, inference, robust covariances, predictions, etc.) is derived from and supersedes the ivreg () function in the AER package.

Instrumental variables estimation - Wikipedia

Introduction The concept of instrumental variables was first derived by Philip G. Wright, possibly in co-authorship with his son Sewall Wright, in the context of simultaneous equations in his 1928 book The Tariff on Animal and Vegetable Oils. In 1945, Olav Reiersøl applied the same approach in the context of errors-in-variables models in his dissertation, giving the method its name.
