ivcrc: An instrumental-variables estimator for the correlated random-coefficients model

We discuss the ivcrc command, which implements an instrumental-variables (IV) estimator for linear correlated random-coefficients model. The model is a natural generalization of standard IV that allows endogenous, multivalued treatments and unobserved heterogeneity in treatment effects. implemented by uses recent semiparametric identification results allow flexible functional forms permit instruments may be binary, discrete, or continuous. command also estimation varying-coefficient regressions, are closely related structure to proposed estimator. illustrate use estimating returns education National Longitudinal Survey Young Men.
