DESCRIPTION:Decision makers desire to implement decision rules that\, when
  applied to individuals in the population of interest\, yield the best pos
 sible outcomes. For example\, the current focus on precision medicine refl
 ects the search for individualized treatment decisions\, adapted to a pati
 ent's characteristics. In this presentation\, I will consider how to formu
 late\, choose and estimate effects that guide individualized treatment dec
 isions. In particular\, I will introduce a class of regimes that are guara
 nteed to outperform conventional optimal regimes in settings with unmeasur
 ed confounding. I will further consider how to identify or bound these "su
 peroptimal" regimes and their values. The performance of the superoptimal 
 regimes will be illustrated in two examples from medicine and economics.
