Unmeasured confounding is a threat to causal inference and individualized decision making. Similar to Cui and Tchetgen Tchetgen (2020); Qiu et al. (2020); Han (2020a), we consider the problem of identification of optimal individualized treatment regimes with a valid instrumental variable. Han (2020a) provided an alternative identifying condition of optimal treatment regimes using the conditional Wald estimand of Cui and Tchetgen Tchetgen (2020); Qiu et al. (2020) when treatment assignment is…

It is argued that when faced with unmeasured con-founding, one should pursue individualized decision making using partial identiﬁcation in a comprehensive manner and a novel minimax solution is provided (i.e., a rule that minimizes the maximum regret for so-called opportunists) for individualization decision making/policy assignment.

Identification of Causal Effects Using Instrumental Variables

- Mathematics, Computer Science

It is shown that the instrumental variables (IV) estimand can be embedded within the Rubin Causal Model (RCM) and that under some simple and easily interpretable assumptions, the IV estimand is the average causal effect for a subgroup of units, the compliers.

Novel assumptions are proposed that allow for identification of the average treatment effect (ATE) under the standard IV model and are clearly separated from model assumptions needed for estimation, so that researchers are not required to commit to a specific observed data model in establishing identification.

A functional interval estimator is developed that predicts bounds on the individual causal effects under realistic violations of unconfoundedness and is proved that it converges exactly to the tightest bounds possible on CATE when there may be unobserved confounders.

It is demonstrated that hidden confounding can hinder existing policy learning approaches and lead to unwarranted harm, while the robust approach guarantees safety and focuses on well-evidenced improvement, a necessity for making personalized treatment policies learned from observational data reliable in practice.
