Hood(1953)—with the first developments of 2SLS appearing inTheil(1953) andBasmann(1957). However,Stock and Watson(2019, 401–402) present an example of the method of instrumental variables that was first published in1928by Philip Wright.

Such a procedure is called two-stage least squares (2SLS) for an obvious reason. In this case, the IV estimator and the 2SLS estimator are numerically equivalent as shown in Exercise 9 below. Example 2 (Omitted Variables) Mundlak (1961) considered the

Two-Stage Least Squares - Brenton Kenkel

Our goal now is to see that two-stage least squares gives us the same answer. Consider the first-stage regression, Ti = 0 + 1Zi + i. You know from your previous adventures with regression that the OLS esti-mates will be ˆ0 = T¯ Z=0 and ˆ1 = T¯Z=1 T¯Z=0.The
