Stata Tutorial: Basics of Instrumental Variables and Two-Stage Least Squares

We cover the basic theory and derivations of the Instrumental Variable and Two-Stage Least Squares estimators, then walk through an example of each in Stata.


We use the "ivreg" command, and apply the example to publicly available data accessed through the "bcuse" package.
