    • A Geometric Approach to Weakly Identified Econometric Models 

      Andrews, Isaiah; Mikusheva, Anna (Cambridge, MA: Department of Economics, Massachusetts Institute of Technology, 2012-05-29)
      Many nonlinear Econometric models show evidence of weak identification, including many Dynamic Stochastic General Equilibrium models, New Keynesian Phillips curve models, and models with forward-looking expectations. In ...

    • Maximum Likelihood Inference in Weakly Identified DSGE Models 

      Andrews, Isaiah; Mikusheva, Anna (Cambridge, MA: Department of Economics, Massachusetts Institute of Technology, 2011-03-21)
      This paper examines the problem of weak identification in maximum likelihood, motivated by problems with estimation and inference a multi-dimensional, non-linear DSGE model. We suggest a test for a simple hypothesis ...

    • Robust Two-Step Confidence Sets, and the Trouble with the First Stage F-Statistic 

      Andrews, Isaiah (2014-09-04)
      When weak identification is a concern researchers frequently calculate confidence sets in two steps, first assessing the strength of identification and then, on the basis of this initial assessment, deciding whether to use ...
