Breusch-Godfrey and 2SLS

Postby startz » Thu Sep 24, 2009 5:54 pm

Does anyone happen to know if the standard Breusch-Godfrey LM test for serial correlation is valid when the residuals are from two-stage least squares. My not-too-well-informed impression is that it is not.

Some guy called Jeff Wooldridge has a paper "A note on the Lagrange multiplier and F-statistics for two stage least squares regressions" (Econ Letters, Oct. 1990), that covers this.

The Wooldridge paper could be seen as a generalisation of an earlier paper (1983, Econ Letters) by some guy called Richard Startz.

I'd missed that the auxiliary regression was by 2SLS.

but then, how could anyone with such great taste in literature ever go wrong?
