Contract Type FiledNovember 20th, 2018because the right side includes a potential mean outcome, (Y¯ (Z = 0, L = n)), which cannot be estimated in the observable world based on assumptions made so far. However, the exclusion restriction assumes that the treatment effect amongst those who do not comply is zero, implying that mean outcome for non-compliers in the active intervention and control trial arms are exchangeable. Substituting (Y¯10) for (Y¯ (Z = 0, L = n)), and simplifying by expressing (Y¯1.) − (1 − αˆc)(Y¯10) as αˆc(Y¯11), Equation 4.4 can be expressed in observable terms as an estimator for β :
