  author={Charles F. Manski},
This paper develops a broad theme about treatment under ambiguity through study of a particular decision criterion. The broad theme is that a planner may often want to cope with ambiguity by diversification, assigning observationally iden tical persons to different treatments. Study of t he m inimax-regret (MR) criterion substantiates the theme. The paper significantly extends my earlier analysis of one-period planning with individualistic treatment a nd a linear welfare function. I show that…

Choosing Treatment Policies Under Ambiguity
Economists studying choice with partial knowledge typically assume that the decision maker places a subjective distribution on unknown quantities and maximizes expected utility. Someone lacking a
Policy Learning Under Ambiguity
This paper studies the problem of estimating individualized treatment rules when treatment effects are partially identified, as it is often the case with observational data. We first study the
Minimax Regret Treatment Choice with Limited Validity of Experiments or with Covariates
This paper continues the investigation of minimax regret treatment choice initiated by Manski (2004). Consider a decision maker who must assign treatment to future subjects after observing outcomes
New Perspectives on Statistical Decisions Under Ambiguity
This review summarizes and connects recent work on the foundations and applications of statistical decision theory by discussing global, finite-sample admissible, and minimax decision rules for a number of stylized decision problems with point and partial identification.
Smooth Aggregation of Bayesian Agents
I study the ex-ante aggregation of preferences of Bayesian agents in a purely subjective framework. Unlike Gilboa et al. (2004), I relax the assumption of Bayesian society while keeping the Pareto
Diversification Behavior of Individuals over Potential Losses under Risk and Ambiguity
People constantly face uncertain prospects in life, many of which may result in losses such as illnesses, accidents, and disasters. In the field of Decision Sciences, these uncertainties can be
Policy choice with partial knowledge of policy effectiveness
An important objective of policy research is to provide information useful in choosing new policies. Consider a planner, who must choose treatments for the members of a population. Policy analysts

Statistical treatment choice based on asymmetric minimax regret criteria
Statistical treatment rules for heterogeneous populations
An important objective of empirical research on treatment response is to provide decision makers with information useful in choosing treatments. This paper studies minimax-regret treatment choice
Social Choice with Partial Knowledge of Treatment Response
textabstractEconomists have long sought to learn the effect of a "treatment" on some outcome of interest, just as doctors do with their patients. A central practical objective of research on
Social Planning with Partial Knowledge of Social Interactions
Economists studying collective decision problems often consider how a social planner would behave. The standard exercise presumes complete knowledge of the welfare achieved by each feasible policy.
Search Profiling with Partial Knowledge of Deterrence
This work considers the choice of a profiling policy where decisions to search for evidence of crime may vary with observable covariates of the persons at risk of being searched, and poses a planning problem whose objective is to minimize the utilitarian social cost of crime and search.
Social Learning from Private Experiences: The Dynamics of the Selection Problem
I analyse social interactions that stem from the successive endeavours of new cohorts of heterogeneous decision makers to learn from the experiences of past cohorts. A dynamic process of information
Ordinal utility models of decision making under uncertainty
This paper studies two models of rational behavior under uncertainty whose predictions are invariant under ordinal transformations of utility. The ‘quantile utility’ model assumes that the agent
Partial Prescriptions for Decisions with Partial Knowledge
This paper concerns the prescriptive function of decision analysis. I suppose that an agent must choose an action yielding welfare that varies with the state of nature. The agent has a welfare
