19/1/2012 · As a follow-up to an earlier post, I was pleasantly surprised to discover that the code to handle two-way cluster-robust standard errors in R that I blogged about earlier worked out of the box with the IV regression routine available in the AER package (ivreg). Here's the

• ### On the LIML estimation of a structural equation by an iterative …

1/1/1981 · Incidentally, dropping the terms involving b* one obtains the 2SLS equations which one must, since the 2SLS does not incorporate this information. Second, it is apparent why the LIML is no more efficient asymptotically than the 2SLS, despite the fact that the former does, and the latter does not, utilize sample covariance information.

• ### econometrics - why is 2SLS with dummys the same as GLS on group means? - Cross Validated

I'm reading Mostly Harmless Econometrics (Available here), and on page 100 they say that 2SLS with dummy instruments is the same as GLS on a set of group means. I don't understand why. From the previous chapters, I got how instrumental variables work in general, but im struggling to differentiate between the Wald Estimator, 2SLS and grouped data.

2 This is the 2SLS estimator. It is called as two-stage because it looks like we take two steps by creating projected X to estimate the 2SLS estimators. We do not need to take two steps as we show in (2). We can just estimate 2SLS estimators in one stepX
