An intuitively natural consistency condition for contingent plans is necessary and sufficient for a contingent plan to be rationalized by maximization of conditional expected utility. One alternative theory of choice under uncertainty, the weighted-utility theory developed by Chew Soo Hong...

In a finite-trader version of the Diamond-Dybvig (1983) model, the symmetric, ex-ante efficient allocation is implementable by a direct mechanism (i.e., each trader announces the type of his own ex-post preference) in which truthful revelation is the strictly dominant strategy for each trader....

This paper provides a construction of an uncountable family of i.i.d. random vectors, indexed by the points of a nonatomic measure space, such that (a) samples are measurable functions from the index space, and (b) an exact analogue of the Glivenko-Cantelli theorem holds with respect to the...

These notes concern a model of an economy where the following four things happen in an equilibrium. + Fiat money is useful as a medium of exchange. Consequently it has value. + Some trades are also financed by the issuance of private IOUs, and money must be used to pay these off. + Besides there...

A current U.S. policy is to introduce a new style of currency that is harder to counterfeit, but not immediately to withdrawal from circulation all of the old-style currency. This policy is analyzed in a random-matching model of money, and its potential to decrease counterfeiting in the long run...

This paper studies the existence of single-price price equilibrium from a given initial distribution of money holdings in a search-theoretic model of money where agents have no time preference. The model is similar to the authors' recent models of search economies with no constraints on money...

Laboratory experiments concerning decision under uncertainty tend to uncover systematic violations of Bayesian rationality. When models that posit Bayesian rationality are compared to non-experimental data, though, they fit the data well. One possible explanation is that an agent's global...

We consider a version of Kiyotaki and Wright's monetary search model in which agents can hold arbitrary amounts of divisible money. A continuum of stationary equilibria, indexed by the aggregate real-money stock, exist with all trading occurring at a single price. There is always a maximum level...

The broad concept of an individual's welfare is actually a cluster of related specific concepts that bear a ``family resemblance'' to one another. One might care about how a policy will affect people both in terms of their subjective preferences and also in terms of some notion of their...
