Avoiding Invalid Instruments and Coping with Weak Instruments
A rchimedes said, “Give me the place to stand, and a lever long enough, and I will move the Earth” (Hirsch, Kett, and Trefil, 2002, p. 476). Economists have their own powerful lever: the instrumental variable estimator. The instrumental variable estimator can avoid the bias that ordinary least squares suffers when an explanatory variable in a regression is correlated with the regression’s distu...
متن کاملWeak/Invalid Instruments in Simultaneous Equation Models: Detection and Estimation
This note is a resume of Jerry Hausman’s Nake course at the NAKE workshop in Den Haag, The Netherlands in June 2002. It presents an intuitive framework in which the impact of weak/invalid instruments on properties of di¤erent estimators can be analyzed while also suggesting a test to detect the presence of weak/invalid instruments.
متن کاملIV estimation with valid and invalid instruments
While 2SLS is the most widely used estimator for simuhaneous equation models, OLS may do better in finite samples. Here we demonstrate analytically that the for the widely used simultaneous equation model with one jointly endogenous variable and valid instruments, 2SLS has smaller MSE error, up to second order, than OLS unless the R , or the F statistic of the reduced form equation is extremely...
متن کاملIdentification and Inference With Many Invalid Instruments
We study estimation and inference in settings where the interest is in the effect of a potentially endogenous regressor on some outcome. To address the endogeneity we exploit the presence of additional variables. Like conventional instrumental variables, these variables are correlated with the endogenous regressor. However, unlike conventional instrumental variables, they also have direct effec...
متن کاملInference with Weak Instruments
This paper reviews recent developments in methods for dealing with weak instruments (IVs) in IV regression models. The focus is more on tests (and confidence intervals derived from tests) than estimators. The paper also presents new testing results under “many weak IV asymptotics,” which are relevant when the number of IVs is large and the coefficients on the IVs are relatively small. Asymptoti...
