Prospect Theory: For Risk and Ambiguity, provides a comprehensive and accessible
textbook treatment of the way decisions are made both when we have the statistical …

A sequentially rationalizable choice function is a choice function that can be retrieved by
applying sequentially to each choice problem the same fixed set of asymmetric binary …

We study the problem of obtaining an expected utility representation for a potentially
incomplete preference relation over lotteries by means of a set of von Neumann …

We study a market model in which competing firms use costly marketing devices to influence
the set of alternatives which consumers perceive as relevant. Consumers in our model are …

In 1908, the Welsh neurologist and psychoanalyst Ernest Jones described human beings as
rationalizers whose behavior is governed by “the necessity of providing an explanation.” We …

There is well-established evidence that decision makers consistently fail to consider all
available options. Instead, they restrict attention to only a subset of alternatives and then …

This paper proposes a model in which identical sellers of a homogeneous product compete
in both prices and price frames (ie, ways to present price information). Frame choices affect …

Recent advances in decision making have incorporated both risk and ambiguity in decision
theory and optimization methods. These methods implement a variety of uncertainty …

We develop the ordinal theory of (semi) continuous multi-utility representation for incomplete
preference relations. We investigate the cases in which the representing sets of utility …

Many individuals' choices and valuations involve a degree of uncertainty/imprecision. This
paper reports an experiment designed to obtain some measure of imprecision and to …
