Query: On a necessary and sufficient identification condition of optimal
  treatment regimes with an instrumental variable   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 subject to endogeneity
and a valid binary instrumental variable is available. In this note, we provide
a necessary and sufficient condition for identification of optimal treatment
regimes using the conditional Wald estimand. Our novel condition is necessarily
implied by those of Cui and Tchetgen Tchetgen (2020); Qiu et al. (2020); Han
(2020a) and may continue to hold in a variety of potential settings not covered
by prior results.
