Comparing IV with Structural Models: What Simple IV Can and Cannot Identify

Sergio Urzua and James Heckman

No 200906, Working Papers from Geary Institute, University College Dublin

Abstract: This paper compares the economic questions addressed by instrumental variables estimators with those addressed by structural approaches. We discuss Marschak's Maxim: estimators should be selected on the basis of their ability to answer well-posed economic problems with minimal assumptions. A key identifying assumption that allows structural methods to be more informative than IV can be tested with data and does not have to be imposed.
