http://pallavr.rbind.io/blog/2024-06-26-fwl-theorem/ 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.
