This paper establishes that instruments enable the identification of nonparametric regression models in the presence of measurement error by providing a closed form ...

This paper extends the usual Instrumental Variables estimator of the parameters of a linear regression involving stochastic regressors to the case where these parameters are subject to exact linear ...

The estimation of economic relationships often confronts the challenge of weak instruments – variables that are only weakly correlated with endogenous regressors. Such weakness can lead to substantial ...

A frequent problem in the estimation of linear regression models is that the predictors are correlated with the error term contained in the regression equation. To ...

The first form of the INSTRUMENTS statement is used only before a FIT statement and defines the default instruments list. The items specified as instruments can be variables or the special keyword ...
