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...

We construct a simple three person trust game with one trustor and two trustees. The trustorhas the possibility to either trust both trustees or none, while the trustees make their decisionseither sequentially or simultaneously, depending on the treatment. When trustees play...

Social institutions regulating group conduct have been regarded as necessaryfor human cooperation to transcend family bonds. However, manystudies in economics and biology indicate that reciprocity based on repeatedinteraction suffices to establish cooperation with non-kin. We shedlight on the...

Actual behaviour is inuenced in important ways by moral emotions,for instance guilt or shame (see among others Tangney et al., 2007). Belief-dependant models of social preferences using the framework of psycho-logical games aim to consider such emotions to explain other-regardingbehaviour. Our...

A decision maker (DM) wishes to select a competent candidate to …ll a position.However, since the wage and task of the position is predetermined, the DM cannot usecontract as a screening device. This paper formulates the problem as a class of selectionproblem and derives the optimal selection...

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 revisit the economic models of social learning by assuming that individuals update theirbeliefs in a non-Bayesian way. Individuals either overweigh or underweigh (in Bayesian terms)their private information relative to the public information revealed by the decisions of othersand each...

We analyse pricing, e¤ort and tipping decisions in the online service GoogleAnswers. While users set a price for the answer to their question ex ante, theycan additionally give a tip to the researcher ex post.In line with the related experimental literature we …nd evidence that tippingis...

Recent literature has questioned the existence of a learning foundationfor the partially cursed equilibrium. This paper closes the gap by showingthat a partially cursed equilibrium corresponds to a particular analogy-based expectation equilibrium.
