We investigate the effect of absence of common knowledge on the outcomes of coordination games in a laboratory experiment. Using cognitive types, we can explain coordination failure in pure coordination games while differentiating between coordination failure due to first- and higher-order...

We present two new notions of evolutionary stability, the trulyevolutionarily stable state (TESS) and the generalized evolutionarilystable equilibrium (GESE). The GESE generalizes the evolutionar-ily stable equilibrium (ESE) of Joosten [1996]. An ESE attracts allnearby trajectories...

A common feature of the literature on the evolution of preferencesis that evolution favors nonmaterialistic preferences only if preferencetypes are observable at least to some degree. We argue that this resultis due to the assumption that in each state of the evolutionary dynam-ics some Bayesian...

We suggest a simple asset market model in which we analyze competitive and strategic behavior simultaneously. If two-fund separation is found to hold across periods for competitive behavior, it also holds for strategic behavior. In this case the relative prices of the assets do not depend on...

This paper examines the occurrence and fragility of information cascades in laboratory experiments.One group of low informed subjects make predictions in sequence. In a matchedpairs design, another set of high informed subjects observe the decisions of the first group andmake predictions....

The common prior assumption justifies private beliefs as posterior probabilities when updatinga common prior based on individual information. Common priors are pervasive in most economicmodels of incomplete information and oligopoly models with asymmetrically informed firms. Wedispose of the...

We study sequential parimutuel betting markets with asymmetrically informed bettors, usingan experimental approach. In one treatment, groups of eight participants play twenty repetitionsof a sequential betting game. The second treatment is identical, except that bettors are observedby other...

Dieser Beitrag erweitert die Standardmodellierung der Literatur über Informationsaustausch zwischen Unternehmen bei Nachfrageunsicherheit und läßt sich vor allem auf Unternehmen in neuen Branchen oder in unsicheren Märkten anwenden ...

Candidates compete to persuade a decision maker. The decision maker wishes toselect a candidate who possesses a certain ability. Then, as a signaling, each candidatedecides whether to perform a task whose performance statistically re‡ects the ability.However, since the cost of the performance...

This paper purports to provide experimental evidence explaining a number of stylized facts associated with thebehaviour of financial returns, in particular, the fat tailed nature of their distribution and the persistence in theirvolatility. By means of a laboratory experiment, we will...
