Lecture: IV and 2SLS Estimators (Wooldridge's book chapter 15)

2SLS is also called IV estimator. b 1 is over-identified if there are multiple IVs. b 1 is under-identified if there is no excluded exogenous variable. For instance, we have over-identification if we know the number of raining days and the number of snowy days. If 5

Three-stage Least Squares (3SLS) ¶. This example demonstrates how a system of simultaneous equations can be jointly estimated using three-stage least squares (3SLS). The simultaneous equations model the wage and number of hours worked. The two equations are. h o u r s = β 0 + β 1 ln. ⁡.

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

Lecture 8: Instrumental Variables Estimation

This is the 2SLS estimator. It is called as two-stage because it looks like we take two steps by creating projected X to estimate the 2SLS estimators. We do not need to take two steps as we show in (2). We can just estimate 2SLS estimators in one step byX
