Strotz meets Allais: Diminishing Impatience and the Certainty Effect
Decision makers tend to exhibit a higher degree of impatience when considering a delay to an immediate reward than when contemplating an identical delay to an equal future reward. This work argues that diminishing impatience originates from the distinction between the certain present and the risky future. A simple functional representation of preferences, which exhibits time inconsistency when the future is uncertain, is derived. Existing experimental evidence, which is inconsistent with other formulations that account for diminishing impatience, supports the proposed approach. Furthermore, the new theory uncovers a tight relation between diminishing impatience and well-known behavioral regularities in the field of choice under risk and uncertainty
