On November, 11th, 1630, Queen Marie de’ Medici demanded, in vain, that her son, King Louis XIII, dismiss Richelieu as Principal Minister. Historians agree that this crisis known as the Journée des Dupes ( the Day of the Dupes) was the true foundation stone of French “absolutism”, but they disagree about whether the decision made by the Queen was r...

How to share the cost of an improvement in a condo? In France, as in most European civil law countries, the law does not provide any precise method for answering this question. This vagueness of the law calls for further investigation. Focusing on how to distribute costs that are collectively incurred by a group of players, cooperative game theory...

In both the United States of America and the European Union, Member States are encouraged to prevent young people from starting to smoke by forbidding selling tobacco products to people under a certain age. By contrast, there are in general no legal minimum age requirements for consuming those products. Our aim is to address such discrepancy from a...

We propose an original game‐theoretic demand‐induced supply model of overtreatment with heterogeneous experts. We show that experts, whatever their abilities, must give the treatment if customers expect them to do so. We show how launching awareness campaigns (on the prudent use of treatment) disseminating information to both the general public and...

How to enhance the maintenance, repair and improvement of condo buildings? We address this issue by focusing on the case of an elevator installation whose benefits are not uniform across units. We examine the link between majority approval and cost sharing. Relying on a cooperative game theory approach, we prove the coalitional stability of any cos...

On the Ides of March, 44 BC, in the Senate House of Pompey in Rome, Julius Caesar was assassinated by conspirators, the most famous of those being Brutus. Are there objectively valid reasons to confirm the possibility of a suicidal wish on the part of Caesar raised by Suetonius? By building and solving a two-player non-cooperative game that models...

1. ABSTRACT Introducing digital educational games into class lessons can generate engagement, interactivity, and motivation. It can also result in an active participation of the students in the classroom. To achieve this goal, one teaching strategy is to use online digital games in teaching and learning situations. In our case, we wanted to test th...

Numerous papers show how game theory can improve our understanding of literature. There is no paper, however, using experimental economics to arrive at a new understanding of a play. We fill this gap by using experimental evidence to compare the last two versions of Molière's Tartuffe. In the final version of the play, there are two stag hunt games...

According to Merton 11957), the history of science is punctuated by disputes over priority of discovery, but there are no such priority fights in economics. Hands [2006] explains this phenomenon by assuming that economists have no sense of collective moral outrage. We provide a counterexample to this thesis by developing a gametheoretic analysis of...

In common law legal systems, there is no legal duty to rescue persons in danger. By contrast in code-based legal systems, the principle of duty to rescue does apply. What is behind this difference? To answer this question, we develop a new model extending the reach and strength of the standard civic duty game by taking into account the cost of wron...

Both the choice between “stick” and “carrot” and the tension between “control” and “preservation of civil liberties” characterize the policy debate over counterterrorism. Arguing for the “carrot and preservation of civil liberties” viewpoint, Frey and Rohner (Def. Peace Econ. 18(3):245–252, 2007) propose strategic reconstruction as an alternative t...

The majority American rule on omissions is that there is no legal duty to rescue persons in danger. By contrast, the New French Penal Code and most Western European civil laws impose a duty to aid persons in danger. Which system is better ? What does "better" mean in that context ? To address these issues, we combine a game-theoretic model inspired...

In Rome, on 16 March 1978, the Red Brigades kidnapped Aldo Moro. They kept him a prisoner for 55 days, and ultimately killed him. Why did they decide to kill Moro since it appears a posteriori that they did not improve their situation by doing so? Our paper answers this question by building mainly on the model of kidnapping by Selten (A simple game...

This paper analyses the determination of the complexity of legal rules in a context of harmonization between different countries. We first assume that there are no harmonization gains. We show that if the optimal complexity levels of legal rules are equal across countries, their common level will stick when legal rules are harmonized. When these le...

We study the desirability of interventionist harmonization of legal standards across multiple, mutually interdependent jurisdictions which strive to adapt law to their local conditions as well as to synchronize it with other jurisdictions. In a setting where jurisdictions are privately informed about their local conditions, we contrast the regime o...

Unification of legal rules in Europe is not a new phenomenon. However, nowadays, Europe is still an area with many different jurisdictions. This paper studies the process of unification of legal rules in the European Union within a non-cooperative game-theoretical framework. This paper contributes to the understanding of the process by concentratin...

Both Poe and Dupin, the detective character created by Poe, think like game theorists. The goal of this paper is to prove this conjecture. First, we show that each one of the three Dupin stories is filled with ratiocination that can be modeled according to game theory. Second, we briefly elaborate on the bargaining game that is lurking beneath the...

Existing French bankruptcy/insolvency law is composed of extra-judicial treatment of firms?difficulties and judicial treatment of their failures. In the first part, there is mediation. French mediation procedure falls mainly within the province of bargaining theory. However, during the negotiation between the manager of the failing firm and its chi...

Present French bankruptcy law is composed of extra-judicial (prevention and mediation) treatment of firms’ difficulties and judicial treatment (bankruptcy reorganization and liquidation) of their failures. In the first part, mediation belongs to non-cooperative game theory and to economics of information. In the second part, liquidation belongs to...

SETTLEMENT, TRIAL AND GAME THEORY: AN APPRAISAL AND AN APPLICATION The litigation of a dispute follows a definite and well-worn path. If Victim wants to recover damages from Injurer, the lawsuit begins when Victim files a complaint. Injurer is required to file an answer. Next the parties engage in discovery. At any point during the process, the par...

[fre] Juridiquement, toute instance se decompose en trois phases : engagement, mise en etat, jugement. Dans la litterature economique, ce triptyque se presente aujourd'hui principalement sous la forme d'un jeu non cooperatif dynamique a information incomplete dans lequel les joueurs sont les parties et dont l'issue peut etre une transaction ou un j...

[eng] Experimental methods, economics and game theory : "nunc est bibendum ". This paper aims at answering a question about the development of experimental economics : Quis, quid, ubi, quibus auxiliis, cur, quomodo, quando ?. It offers a brief historical account of the emergence of an experimental tradition in economics and our own tentative explan...

[fre] Prospection et accueil d'entreprises par les régions. Un problème gigogne de décision conjointe. . Dans sa quête de nouvelles entreprises, chaque région française est confrontée à trois problèmes de décision conjointe. Le premier consiste en l'organisation d'une « chasse au cerf » où les collectivités locales et les entreprises tiennent respe...

This paper is devoted to a study of Walras's correspondence as a test of Aumann's conjecture. First, we use the Walras-Jevons correspondence as a "battle of the sexes" experiment to show that, in such a game preceded by one round of two-way communication, sequential announcements may help a lot even when messages about actions are not to take liter...

This paper is devoted to a study of Walras's correspondence as a test of the effectiveness of cheap talk in achieving efficient outcomes. First, through a survey of two famous game-theoretic analyses of historical facts, we show that letters matter. Second, building on these studies, we bring game theory, experimental economics and history of econo...
