TY - RPRT AU - Imbens, Guido W. TI - Instrumental Variables: An Econometrician's Perspective PY - 2014/Mar/ PB - Institute of Labor Economics (IZA) CY - Bonn T2 - IZA Discussion Paper IS - 8048 UR - https://www.iza.org/publications/dp8048 AB - I review recent work in the statistics literature on instrumental variables methods from an econometrics perspective. I discuss some of the older, economic, applications including supply and demand models and relate them to the recent applications in settings of randomized experiments with noncompliance. I discuss the assumptions underlying instrumental variables methods and in what settings these may be plausible. By providing context to the current applications a better understanding of the applicability of these methods may arise.
