Using a system of axioms, this paper develops a general utility model of other-regarding preferences when opponents are unfamiliar, but they are not strictly anonymous in the sense that they may share some history. Based on two key axioms, an individual’s preferences over a vector of probability distributions are additively separable in the decision maker’s own outcome and each opponent’s outco...
We characterize preferences over acts that can be represented by a utility function and a multiple–prior, such that an act f is preferred to act g if there is a prior under which the expected utility induced by f is higher than that induced by g. These preferences are referred to as justifiable preferences. We further introduce a generalized model of ambiguity that involves a collection of mult...
We provide a simple proof for the existence of an expected utility representation of a preference relation with an unbounded and continuous utility function. © 2014 Elsevier B.V. All rights reserved.
Researchers have shown that many, though not all, of the basic results of expected utility analysis can be more or less directly generalized to non-expected utility preferences. This paper describes the essential difference between results which can be extended in this manner and those which cannot and shows that an important family of comparative statics theorems falls into the former class. J...
In this paper we describe a utility computing framework, consisting of a component model, a methodology, and a set of tools and common services for building utility computing systems. This framework facilitates the creation of new utility computing systems by providing a set of common functions, as well as a set of standard interfaces for those components that are specialized. It also provides ...
Utility mining in data mining has recently been an emerging research issue due to its practical applications. In this paper, with the concept of projection technique, we propose an efficient algorithm for finding high utility itemsets in databases. In particular, an improved upper-bound strategy in the proposed algorithm is designed to further tighten the upper bounds of the utility values for ...
