WebIn a simple OLS setting, the Frisch-Waugh-Lovell Theorem (Frisch and Waugh,1933;Lovell, 1963) provides our point of departure. According to this, when the outcome variable is directly regressed on the shock (without controls), the OVB is zero such that the one and two-step ap-proaches yield identical coefficient estimates.

The first few times I saw the Frisch-Waugh-Lovell theorem in practice, I did not appreciate it. However, I’ve become a pretty big fan of it—FWL is helpful in a number of ways. 7 The theorem can give you some interesting insights into what is going on inside of OLS, how to interpret coefficients, and how to implement really messy regressions.
