Instrumental variables, local instrumental variables and control functions [PDF]

We consider the identification of the average treatment effect in models with continuous endogenous variables whose impact is heterogeneous. We derive a testable restriction that allows us to assess the degree of unobserved heterogeneity. Our analysis uses assumptions relating to the Local Instrumental Variables (LIV) approach and the control function ...

Two-stage least squares model averaging for instrumental variable models with exogenous variables

Statistical Theory and Related Fields
Instrumental variable (IV) methods are widely used to address unmeasured confoundings in structural equation models. In this paper, we focus on the settings where a possibly large number of instruments and a weak correlation between the instruments and ...
