The main result shows that the settlement rule tends to chill bargaining as it creates incentives for individuals to misrepresent their true valuations, which implies that automated negotiation is not able to promote agreements. However, this perverse effect depends strongly on the conflict situation. When the threat that a disagreement occurs is more credible, the strategic effect is reduced since defendants are more interested in maximizing the efficiency of a settlement than their own expected profit. The implications of these results are then used to discuss the potential role of public regulation and reputation mechanisms in Cyberspace.

We study the incentives of CSD to migrate to TARGET 2 Secruities when they are competitors in the market for depository. In the spirit of Matutes and Padilla (1994), we construct a stylized model of CSD competition which emphasises the distinctive features of SSS compatibility. We investigate the trade-off between the network and the substitution effects in a setting where, rival CSD first agree on a compatibility regime and then compete in Securities Settlement Services and depository. Therefore, we derive the implications for CSD compatibility of post-trading cost, entry, and banks switching costs. Finally, we investigate the normative implications of our model and draw some policy conclusions.

Une étude expérimentale Yannick Gabuthy et Nadège Marchand This paper presents the results of an experiment performed to test the properties of an innovative bargaining mechanism (called automated negotiation) used to resolve disputes arising from Internetbased transactions. Automated negotiation is an online sealed-bid process in which an automated algorithm evaluates bids from the parties and settles the case if the offers are within a prescribed range. The observed individual behavior, based on 40 rounds of bargaining, is shown to be drastically affected by the design of automated negotiation. The settlement rule encourages disputants to behave strategically by adopting aggressive bargaining positions, which implies that the mechanism is not able to promote agreements and generate efficiency. This conclusion is consistent with the experimental results on arbitration and the well-k...

Ultimatum et logique économique de la négociation : l'apport de l'économie expérimentale
L'analyse de la negociation par la theorie revient a reduire la variete de regles dont dispos... more L'analyse de la negociation par la theorie revient a reduire la variete de regles dont disposent les differentes parties pour parvenir a un accord. Dans cette perspective, le modele de rubinstein (1982) offre une resolution d'un jeu de negociation sequentielle, a offre alternee et en horizon fini. En mobilisant le principe de 'l'induction a rebours', on identifie un equilibre parfait en sous-jeu dans lequel les joueurs parviennent au partage d'equilibre des la premiere etape du jeu. Le jeu d'ultimatum, qui suppose que l'offre faite est a prendre ou a laisser, constitue l'element le plus simple de ce modele. Le partage d'equilibre correspond alors a une repartition tres inegale des gains entre les joueurs. Tout d'abord, l'etude experimentale du jeu d'ultimatum et des jeux de negociation sequentielle revele une preference inarquee pour la repartition egalitaire des gains, ceci contrairement aux predictions de la theorie. L'anomal...

We study experimentally eight such bargaining games. Each game is once repeated before moving on to the next one what defines a cycle of altogether 16 successive plays. Participants play three such cycles. There are no major experience effects but strong and reliable effects of anticipated rule changes. The latter, however, are not due to strategic considerations but rather to the social norms of fairness and efficiency.

One example is the study by Berg et al. (1995) of the investment game. In this game the person who receives the investment is the one who may reward the investor. This is a direct reward game. Similar to Dufwenberg et al. (2000) it is investigated to what extent trust and reward are still observable when reward is indirect; i.e., when the investor may only be rewarded by a third person who did not receive his investment. Furthermore we investigate the influence of social comparison (information about other players' investments). Our main finding is that mainly indirect reward reduces significantly mutual cooperation.

La restructuration des infrastructures de marchés financiers: quelles réformes pour le règlement-livraison et la conservation des titres ?

Elles ont longtemps semble privilegier les « forces naturelles du marche », avant d'inflechir recemment leur position: jugeant les acteurs trop lents a s'organiser et se reformer, la BCE vient ainsi de decider de mettre en place un systeme unique de reglement-livraison des titres financiers. Apres avoir souligne le caractere inabouti de la restructuration de la chaine de traitement des titres en Europe, nous envisageons les differents processus qui pourraient etre engages afin de mener a bien cette consolidation. Puis, nous evaluons les modes d'organisation vers lesquels pourraient evoluer les infrastructures de marche apres la mise en place de ce systeme unique de reglement-livraison. Nous soulignons que des questions restent ouvertes, qui portent notamment sur le devenir de la conservation, la fonction notariale d'enregistrement des titres, traditionnellement associee au reglement-livraison, mais en principe non directement concernee par la future reforme europeenne.

Entrepreneurial (over)confidence and the choice of financing and advising contracts: An experimental investigation

Our theoretical framework proposes that selfconfident entrepreneurs prefer issuing debt whereas low self-confident ones prefer equity which induces strong investor assistance. The prevalence of overconfidence makes investors more reluctant to accept debt offers and constrains self-confident entrepreneurs to finance through mixed securities. Experimental results show that self-confident entrepreneurs issue more debt-like securities and receive less assistance. We also show that entrepreneurs learn not to offer pure debt and that initial ignorance of their own skills reinforces entrepreneurs’ ability to learn through risky choices.
