Reinhard Selten and Thorsten Chmura (2008) recently reported laboratory results for completely mixed 2 X 2 games used to compare Nash equilibrium with four other stationary concepts: quantal response equilibrium, action-sampling equilibrium, payoff-sampling equilibrium, and impulse balance equilibrium. We reanalyze their data, correct some errors, and find that Nash clearly fits...

This article presents the first attempt to formalize the optimization of experimental design with the aim of comparing models of brain function based on neuroimaging data. We demonstrate our approach in the context of Dynamic Causal Modelling (DCM), which relates experimental manipulations to observed network dynamics (via hidden neuronal states) and provides an inference framework...

Online price comparison sites (shopbots) like PriceGrabber.com are the most powerful tools for consumers to easily compare prices and find offers for desired products. Besides providing distributions of actual prices in price comparison tables, shopbots like NexTag.com have recently introduced price charts (line charts) displaying a product's full price history. Price charts...

How effectively do democratic institutions provide public goods? Despite the incentives an elected leader has to free ride or impose majority tyranny, our experiment demonstrates that electoral delegation results in full provision of the public good. Analysis of the experimental data suggests that the result is primarily due to electoral selection: groups elect prosocial leaders and...

Nous proposons une synthèse des recherches sur l'énigme de la baisse de la productivité totale
des facteurs durant la Grande Dépression des années 1930. Cette nouvelle littérature met
l'accent sur l'apport des modèles d'équilibre général dynamique et stochastique pour la
compréhension de cette énigme.
