Consider a problem in which the cost of building an irrigation canal has to be divided among a set of people. Each person has different needs. When the needs of two or more people overlap, there is congestion. In problems without congestion, a unique canal serves all the people and it is enough...

The application of game theory and cognitive economy to analyze the problem of undesired location - The analysts of the processes of public bodies decision - taking have long been discussing on the establishment of proper strategies to manage "environmental conflicts" - above all the so-called...

Voting Power Indices enable the analysis of the distribution of power in a legislature or voting body which uses weighted voting. Although the approach, based on co-operative game theory, has been known for a long time it has not been very widely applied, in part because of the difficulty of...

A set of agents stand to receive a service. No two agents can be served simultaneously. A Queue has been organized, and agents having to wait should receive monetary compensations. We characterize the rule assigning positions in the queue and compensations corresponding to the payoffs...

By generalizing the standard solution for 2-person games into n-person cases, this paper develops a new solution concept for cooperative games: the consensus value.We characterize the consensus value as the unique function that satisfies efficiency, symmetry, the quasi dummy property and...

Consider a group of individuals who have to collectively choose an outcome from a finite set of feasible alternatives. A scoring or positional rule is an aggregation procedure where each voter awards a given number of points, Wj, to the alternative she ranks in Jth position in her preference...

Probabilistic measures of a priori voting power are useful tools to asses actors' influence on collective decision-making either for the purpose of designing a voting organ or to model particular policy cases. This paper makes an attempt to reduce a dynamic voting process into a cooperative...

Each solution concept on a class of normal form games with a given outcome space can be regarded as a social choice correspondence. Here we present a general method of constructing compound solution concepts out of given ones by means of games of pretension.

The condorcet winner in an lection is the candidate who would be able to defeat all other candidates in a series pairwise elections. The Condorcet efficiency of a voting procedure is the conditional probability that it will elect the Condorcet winner, given that a Condorcet exists. The study...

Virtual worlds promise to be an excellent venue for research and education in business and related disciplines. This document provides an introduction to virtual worlds, discusses why virtual worlds are so well-suited to the study of real-world business, and describes how a platform could weave...
