In standard rational choice modelling decisions are made according to given information and preferences. In the model presented here the 'information technology' of individual decision makers as well as their preferences evolve in a dynamic process. In this process decisions are made rationally...

Theoretically and experimentally, we generalize the analysis of acquiringa company (Samuelson and Bazerman 1985) by allowing for competition ofboth, buyers and sellers. Naivety of both is related to the idea that higherprices exclude worse qualities. While competition of naive buyers...

Using a symmetric 2-person prisoners’ dilemma as the base game, each playerreceives a signal for the number of rounds to be played with the same partner.The actual number of rounds (the length of the supergame) is determined bythe maximal signal where each player expects the other’s signal...

In a market with stochastic demand at most one seller can acquire costly informationabout demand. Other sellers entertain idiosyncratic beliefs about the marketdemand and the probability that an informed seller is trading in the market. Theseidiosyncratic beliefs co-evolve with the potential...

In a public goods experiment, subjects can vary over a period of stochasticlength two contribution levels: one is publicly observable (their cheap talkstated intention), while the other is not seen by the others (their secretintention). When the period suddenly stops, participants are restricted...

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...

In the Yes/No game, like in the ultimatum game, proposer and respondercan share a monetary reward. In both games the proposer suggests a rewarddistribution which the responder can accept or reject (yielding 0-payoffs). Thegames only differ in that the responder does (not) learn the suggested...

A robust nding of repeated public goods experiments is that high initialcontribution rates sharply decline towards the end. This paper reports onan exploratory experiment designed to discover whether such a decline is simply triggered by the usual experimental practice of publicly informing...

The common prior assumption asserts that the beliefs of agents in different states of theworld are their posteriors based on a common prior and possibly some private signal. Commonpriors are pervasive in most economic models of incomplete information, oligopoly models withasymmetrically informed...
