Mostly Harmless Econometrics An Empiricist’s Companion

Joshua D. Angrist and Jِrn-Steffen Pischke

The universe of econometrics is constantly expanding. Econometric methods and practice have advanced

greatly as a result, but the modern menu of econometric methods can seem confusing, even to an experienced

number cruncher. Luckily, not everything on the menu is equally valuable or important. Some of the more exotic items are needlessly complex and may even be harmful. On the plus side, the core methods of applied econometrics remain largely unchanged, while the interpretation of basic tools has become more nuanced and sophisticated. Our Companion is an empiricist’s guide to the econometric essentials . . . Mostly Harmless Econometrics.
