On the interpretation of instrumental variables in the presence of specification error
journal contributionposted on 2015-04-24, 15:58 authored by Stephen G. Hall, G. S. Tavlas, P. A. V. B. Swamy
The method of instrumental variables (IV) and the generalized method of moments (GMM), and their applications to the estimation of errors-in-variables and simultaneous equations models in econometrics, require data on a sufficient number of instrumental variables that are both exogenous and relevant. We argue that, in general, such instruments (weak or strong) cannot exist.
