Two-Stage Least Squares (2SLS)/Evidence
Method evidence record

Two-Stage Least Squares (2SLS)

IV/2SLS is a two-stage estimation method that recovers the causal effect of an endogenous regressor by isolating the part of its variation driven by an external instrument. It is the workhorse identification strategy in modern applied econometrics, developed at length in Angrist and Pischke's Mostly Harmless Econometrics (2009).
