Journal of Econometrics, ISSN 0304-4076, 02/2016, Volume 190, Issue 2, pp. 212 - 221
We consider testing for weak instruments in a model with multiple endogenous variables. Unlike Stock and Yogo (2005), who considered a weak instruments problem...

Journal of Econometrics, ISSN 0304-4076, 06/2015, Volume 186, Issue 2, pp. 427 - 442
The use of many moment conditions improves the asymptotic efficiency of the instrumental variables estimators. However, in finite samples, the inclusion of an...

Journal of Econometrics, ISSN 0304-4076, 2012, Volume 166, Issue 2, pp. 255 - 266
This paper shows how valid inferences can be made when an instrumental variable does not perfectly satisfy the orthogonality condition. When there is a mild...
