We recover approximate parametric preferences from consistent and inconsistent consumer choices. The procedure seeks to utilize revealed preference information contained in choices by minimizing its ranking inconsistency with the proposed parametric preferences. We provide a novel...

A sequence of experiments documents static and dynamic ``preference reversals'' between sooner-smaller and later-larger rewards, when the sooner reward could be immediate. The theoretically-motivated design permits separate identification of time-consistent, stationary and time-invariant...

An extension to Ellsberg's experiment demonstrates that attitudes to ambiguity and compound objective lotteries are tightly associated. The sample is decomposed into three main groups: subjective expected utility subjects - who reduce compound objective lotteries and are ambiguity neutral, and...

We study a competitive market for a homogeneous good, in which the only uncertainty concerns the number of identical sellers, who are sampled by a finite Poisson process from a continuum of potential participants. It is shown that, in equilibrium, there is price dispersion. Specifically, prices...

A decision maker with time consistent preferences may exhibit diminishing impatience, when uncertain lifetime is accounted for. Uncertain lifetime captures not only the risk of mortality, but also the possibility that a promise for a delayed reward might be breached, or a postponed consumption...

The Ellsberg Paradox demonstrates that people's belief over uncertain events might not be representable by subjective probability. We show that if a risk averse decision maker, who has a well defined Bayesian prior, perceives an Ellsberg type decision problem as possibly composed of a bundle of...

The Ellsberg experiments provide an intuitive illustration that the Savage approach, which reduces subjective uncertainty to risk, is not rich enough to capture many decision makers' preferences. Recent experimental evidence suggests that decision makers reduce uncertainty to compound risk. This...

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...

The Ultimatum Game seems to be the ideal experiment to test for the structure of preferences or the sequential rationality assumptions underlying subgame perfection. We study the theoretical implications of introducing the possibility of misconceptions - that actions may potentially affect...

Halevy (2008) establishes a relation between non-standard behaviors in the domains of risk and time. A decision maker who believes that only present consumption is certain while any future consumption is uncertain exhibits diminishing impatience if and only if her preferences on the risk domain...
