semiparametric efficiency bound, thereby extending the existing literature on efficient estimation of causal effect to a wider class … of applications. Finally, we discuss estimation of some causal effect functionals such as the treatment effect curve and …-scale simulation study and find that the proposed estimation has practical value. To illustrate the applicability of the procedure, we …
