I've been looking for a good explanation of the difference between running a regression with year dummies as fixed effects vs. year dummies as instrumental variables.

A prominent example of this comes from Josh Angrist's 1991 paper, "Grouped-data estimation and testing in simple labor-supply models"

#### Best Answer

I think the question you are looking to answer is, if you should use a fixed effect model with or without time dummies. The classical text on Panel Econometrics is Econometric Analysis of Cross Section and Panel Data by Jeffrey M Wooldridge. I would suggest this book to answer your question(s). Most university libraries will probably have a copy of this text. If not the economics department probably will. Also, there is an old version of a paper by I. Murtazashvili and J. Wooldridge on that should be enough to answer your question from their department. The title is “FIXED EFFECTS INSTRUMENTAL VARIABLES ESTIMATION IN CORRELATED RANDOM COEFFICIENT PANEL DATA MODELS” and the link can be found below. Hope this helps, good luck!
