Instrumental Variables and the Problem of Endogeneity

WebbThe instrumental variable approach for controlling unobserved sources of variability is the mirror opposite of the propensity score method for controlling observed variables (Angrist et al. 1996, Winship and Morgan 1999).Unlike an observed control variable, an instrumental variable is assumed not to have any direct effect on the outcome. Instead, the … WebbInstrumental Variables (IV) estimation is used when the model has endogenous X’s. IV can thus be used to address the following important threats to internal validity: 1. Omitted variable bias from a variable that is correlated with X but is unobserved, so cannot be included in the regression. 2.
