The ex ante incentive compatible core of an exchange economy with private information is the (standard) core of a characteristic function which expresses the fact that coalitions allocate goods by means of random incentive compatible mechanisms. We first survey some results in the case of...

La plupart des décisions économiques impliquent des agents qui ne partagent pas la même information. Peut-on décrire synthétiquement l’ensemble des procédures accessibles à un planificateur qui souhaite recueillir l’information des agents et agir en leur nom ? Quels sont les critères...

We use a two-issue bargaining model with asymmetric information to study agent choice of how to structure bargaining. We uncover the settings in which different agenda structures are chosen in equilibrium, how the order in which issues are bargained over matters, and what impact the rules for...

The nodes of an extensive-form game are commonly specified as sequences of actions. Rubinstein calls such nodes histories. We find that this sequential notation is superfluous in the sense that nodes can also be specified as sets of actions. The only cost of doing so is to rule out games with...

The theory of international environmental agreements overwhelmingly assumes that governments engage as unitary agents. Each government makes choices based on benefits and costs that are simple national aggregates, and similarly on a single set of national-level motivations, together drawing a...

To explain the strategic dimension in pricing options, it will be helpful to go back to the heart of the idea behind the concept of an option: options open up the possibility to postpone current decisions to a future point of time. Because of this flexibility additional information and new...

We present, for the first time, a model of recent institutional developments in litigation funding across several European jurisdictions. Recognizing the financing constraints that British cost rules may impose on litigants, these new contractual arrangements combine contingency fees with third...

We have experimentally tested a theory of bounded rational behavior in a "lemon market". It provides an explanation for the observation that real world players successfully conclude transactions when perfect rationality predicts a market collapse. We analyzed two different market designs :...

Wir nutzen die Ergebnisse eines Experiments über Lemons-Märkte, um wirtschaftspolitische Folgerungen über die EU-Verbraucherschutzregulierung von 1999 abzuleiten. Die beiden Marktdesigns, die im Experiment getestet wurden, unterscheiden sich hinsichtlich des Grades, zu dem die Verbraucher das...
