Due to factors such as temptation, choices may not respect normative prefer- ence (the agent.s own, subjective view of what constitutes his welfare). Neverthe- less, the evidence on preference reversals suggests a means of recovering normative preference from choice. A de.nition of normative preference in terms of choices between su¢ ciently delayed alternatives is formulated and studied. Mild condi- tions on behavior are shown to ensure the existence of a normative preference. Two characterizations are provided. It is demonstrated that a notion of welfare may exist inspite of dynamic inconsistency of preferences. An application shows that the evidence on hyperbolic discounting implies that agents.normative discount functions must be exponential.
