A predictor is asked to rank eventualities according to their plausibility, based on past cases. We assume that she can form a ranking given any memory that consists of repetitions of past cases.

Prediction is based on past cases. We assume that a predictor can rank eventualities according to their plausibility given any memory that consists of repetitions of past cases. In a companion paper, we show that under mild consistency requirements, these rankings can be represented by numerical...

A consumer has to make a consumption decision. She is modeled as making a binary decision regarding a suggested change to her status quo. An affective package refers to the totality of affective responses that the consumer is expected to have to the various aspects of this decision. It is...

Several authors have indicated a contradiction between consistent aggregation of subjective beliefs and tastes, and a Pareto condition. We argue that the Pareto condition that implies the contradiction is not compelling. Society should not necessarily endorse a unanimous choice when it is based...

In an exchange economy with no aggregate uncertainty, and Bayesian agents, Pareto optimal allocations provide full insurance if and only if the agents have a common prior. It is hard to explain why there is relatively so little betting taking place. One is led to ask, when are full insurance...

We study the Nash bargaining solution of a problem in which two agents bargain over an uncertain outcome. Under the assumption of constant absolute risk aversion, we study the way that solution varies, ex ante, when we vary the beliefs of one agent. Changing an agent's beliefs in a way that...

The art of rhetoric may be defined as changing other people`s minds (opinions, beliefs) without providing them new information. One technique heavily used by rhetoric employs analogies. Using analogies, one may draw the listener`s attention to similarities between cases and to re-organize...
