In this paper, we consider situations where agents face repeatedly the same decision problem. We focus on adaptive rules without beliefs. We distinguish between two kinds of models. Firstly, we study adaptive rules that are only based on private information. Decisions are made on the basis of...

Article 30 of Regulation (EC) No 1907/2006 concerns the sharing of data between users of a chemical substance. We study this bargaining problem by means of a special class of games in coalitional form called data games (Dehez and Tellone, 2013). For such problems, compensation schemes specify...

We study the finitely repeated prisoner’s dilemma in which the players are restricted to choosing strategies which are implementable by a machine with a bound on its complexity. One player must use a finite automaton while the other player must use a finite perceptron. Some examples illustrate...

The EC REACH regulation was enforced the 1st June 2007. REACH requires undertakings to prove the environmental and sanitary innocuousness of their chemical substances. The implementation of this regulation involves the production and exchange of a significant amount of technical and competitive...

This article addresses the question of data-sharing mechanisms under REACH. The members of an information exchange forum have to share their data. This exchange requires the adoption of a compensation scheme : the owner of a data receives a monetary compensation in return for the access to...

We study one aspect of the rationality of players in repeated games. The central assumption is that player?'s choice is limited to strategies that can be computed by a model of computation (or machine). We investigate two of such models : the finite automaton and the perceptron. Each model of...

A single proposer has the opportunity to generate a surplus by taking the assets of a group of individuals. These individuals are called upon to vote for accepting or rejecting the monetary offer made to them by the proposer, who needs the agreement of a qualified majority. The voters who...
