and is only valid when there are more instruments than endogenous variables (overidentified case). So as you both mention it is not a test of exogeneity of the instruments, but rather that the additional restrictions we are imposing by having additional instruments are valid. ...

Any inferences we made about a relationship between the dependent variable and an independent variable when studying one group would be just as valid if we studied this group again at a different time or even if we conducted the study for a different group. Often, applied research is ...
PC1 and PC2 can be calculated using estat ic, see estat ic. Notes: The IC and PC are only valid for static panel models. The IC and PC are intended to identify the optimal set of cross-section averages. DO NOT use the criteria to select the number of lags in a dynamic model. ...
Building on Holtz- Eakin, Newey, and Rosen (1988) and using the GMM framework developed by Hansen (1982), they identify how many lags of the dependent variable, the predetermined variables, and the endogenous variables are valid instruments and how to combine these lagged levels with first ...
