Abstract
The first objective of this paper is to expound the particular challenge posed by the occurrence of inconsistency in the expression of preferences by mental health patients to both economists and policy makers. Since this difficulty cannot be resolved, the second aim of the paper is to identify agents who may be counted upon to identify the true patient preferences. A decision rule is developed to help identify these agents who may be family members or judges in court, who have the ability and incentive to make these decisions. No single agent is found to dominate with respect to the five dimensions of preference distinguished, constituting a major challenge to policy makers.

Notes
This generalization is risky because pertinent research seems to have focused on children and adolescents.
One could define a utility function over these discrepancies to reflect e.g. a difference between a family member and a psychiatrist acting on behalf of the patient, possibly leading to qualifications in the discussion of Table 1 below. However, little is known about agent-specific utility functions.
This condition is satisfied for any effort level between zero and infinity. However, imposing an upper bound such as \( e^{A} + e^{B} \le \bar{e} \) would call for Kuhn–Tucker conditions, considerably complicating the analysis as well as the comparison with Eq. (6) below pertaining to an imperfect agent. Finally, note that the crucial ratio condition of Eq. (3) holds at any effort level.
As pointed out by one of the reviewers, the same issues arise when parents impose a decision on their children; they may not be their best agents in all circumstances.
