...The notion that the observed connection between X and Y might be attributable to additional causal variables has been discussed in other contexts such as endogeneity (Antonakis, Bendahan, Jacquart, & Lalive, 2010) and causal mediation (Imai, Keele, & Tingley, 2010; Pearl, 2014)....

...It can be shown that the availability of such intermediate measurements can make up for the unobservability of all factors that confound T and M (Morgan and Winship, 2007, Ch. 3; Pearl, 2000a, Ch. 3)....

...10, we can condition on W = w, and, using the truncated product formula (Pearl, 2000a, p. 72), we can write CDE(m) = E[Y | do(T = 1,M = m)]− E[Y | do(T = 0,M = m)] = ∑ w E[Y | T = 1,M = m,W = w]P (T = 1,W = w) − E[Y | T = 0,M = m,W = w]P (T = 0,W = w) The reason such conditioning does not work for…...

...The separation condition in (40) is somewhat stronger than (36), since the former implies the latter for every pair of values, t and t∗, of T (see (Pearl 2000, p. 214))....

...…regression analysis of mediation, most notably the one advanced by Baron and Kenny (1986), can be stated as follows: To test the contribution of a given mediator M to the effect of T on Y , first regress Y on T and estimate the regression coefficient RY T , to be equated with the total effect τ ....

...Substituting (39) into (35) and using the law of composition E(Yt∗) = E(Yt∗Mt∗ ) (Pearl 2000, p. 229) gives (37), and completes the proof of Theorem 2....

...…from the perspective of non-parametric structural equation models.5 This approach integrates the potential outcome framework of Neyman (1923) and Rubin (1974) with that of SEM, thus combining mathematical rigor with the merits of staying intimately informed by the data-generating process or its…...

...Counterfactual thinking in statistics (Holland, 1988; Rubin, 1974) and epidemiology (Robins and Greenland, 1992), together with a formal semantics based on non-parametric structural equations (Balke and Pearl, 1995; Halpern, 1998; Pearl, 2001) have given causal mediation analysis a sound theoretical basis and have extended its scope from linear to nonlinear models....
