Traditional mediation analysis based on Ordinary Least Squares (OLS) relies on the absence of unmeasured causes of the putative mediator and outcome. When this assumption cannot be justified, Instrumental Variables (IV) estimators can be used in order to produce an asymptotically unbiased estimator of the mediator-outcome link. However, provided that valid instruments exist, bias removal comes at the cost of variance inflation for standard IV procedures such as Two-Stage Leas","authors_text":"Cedric E.
