Oct 5, 2023 · By Lawrence Susskind — on October 5th, 2023 / Consortium Schools & Other Boston Area Universities, Mediation. The definition of mediation is often as contextual as the conflict it attempts to resolve. Mediation is often thought of as a last step to adjudicate disputes.
Sep 7, 2020 · This chapter reviews methodological advancements with a particular focus on applications in economics. It defines the parameters of interest, covers various identification strategies, for example, based on control variables or instruments, and presents sensitivity checks.

The language of indirect, direct, and total effects evolved in the 1970s, but only recently was the indirect effect defined in causal terms. This shift entailed embracing counterfactual thinking. Let us start with the direct effect using the do-calculus. In the simple graph of treatment (X), mediator (M), and outcome (Y), we get the direct effect o...
The identification of indirect effects becomes more complex when the mediator and the supposed cause (or “exposure”) interact. A unified perspective on the decomposition of the total effect in a case where the independent variable of interest interacts with the mediator has been provided by VanderWeele (2014). So far, effect decomposition has meant...
The graph theory reveals that the identification of causal mechanisms requires counterfactuals. The natural indirect effect is when we abstain from the treatment, but the mediator is present. Contrasted with the state where both the treatment and the mediator are present, we can quantify how much of the effect of X on Y is captured by the mediator ...

Oct 7, 2023 · Mediation analysis is a powerful statistical technique used to understand the relationship between two variables and how one variable influences the other through a mediator variable. To illustrate the importance of mediation analysis, consider the following caselet.
ABSTRACT. This paper presents an econometric mediation analysis. It considers identification of production functions and the sources of output effects (treatment effects) from experimental interventions when some inputs are mismeasured and others are entirely omitted.
