An algorithm for finding the vertices of the k-additive monotone core

Miranda, Pedro; Grabisch, Michel - HAL - 2012

Given a capacity, the set of dominating k-additive capacities is a convex polytope called the k-additive monotone core; thus, it is defined by its vertices. In this paper we deal with the problem of deriving a procedure to obtain such vertices in the line of the results of Shapley and Ichiishi...

Applying relational algebra and RelView to coalition formation

Berghammer, Rudolf; Swart, Harrie De; Rusinowska, Agnieszka - HAL - 2007

We present an application of relational algebra to coalition formation. This leads to speciﬁcations, which can be executed with the help of the RelView tool after a simple translation into the tool's programming language. As an example we consider a simpliﬁcation of the situation in Poland...

Indecisiveness aversion and preference for commitment

Danan, Eric; Guerdjikova, Ani; Zimper, Alexander - HAL - 2012

We present an axiomatic model of preferences over menus that is motivated by three assumptions. First, the decision … decision maker has a preference for commitment in the sense of preferring menus with fewer undominated alternatives. We derive … a representation in which the decision maker's uncertainty about her ex post preferences is captured by means of a …

Lapidus, André - HAL - 2011

Based on Hume's major philosophical works and on some of his Essays, this paper discusses formally the feasibility, from a Humean point of view, of a welfare policy which would aim at promoting the highest individual happiness whereas individual decisions, like individual happiness, are...

Decision Making with Imprecise Probabilistic Information

Gajdos, Thibault; Tallon, Jean-Marc; Vergnaud, … - HAL - 2004

We develop an axiomatic approach to decision under uncertainty that explicitly takes into account the information … available to the decision maker. The information is described by a set of priors and a reference prior. We define a notion of … imprecision for this informational setting and show that a decision maker who is averse to information imprecision maximizes the …

Why Rationality May Be a Consequence of Hume's Theory of Choice

Diaye, Marc-Arthur; Lapidus, André - HAL - 2005

Facing R. Sugden's criticism of our interpretation, it is shown in this paper that rationality appears as a possible consequence of Hume's theory of choice. We first argue that Sugden's dismissal of the preference relation from the type of rationality through which Hume's theory is apprehended,...
