This paper studies the role of exchange policies as a price discrimination device in a sequential screening model with heterogeneous goods. In the first period, agents are uncertain about their ordinal preferences over a set of horizontally differentiated goods, but have private information...

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...

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 unmediated call auction is a useful trading mechanism to aggregate dispersedinformation. Its ability to incorporate information of a single informed insider,however, is less well understood. We analyse this question by presenting a simplecall auction game where both auction prices and limit...

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 consider guilt averse agents and principals and study the effects ofguilt on optimal behavior of the principal and the agent in a moral hazardmodel.The principal’s contract proposal contains a target effort in addition tothe monetary incentive scheme. By accepting the agreement, the...

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...

This paper examines simple parimutuel betting games under asymmetric information,with particular attention to differences between markets in which bets are submittedsimultaneously versus sequentially. In the simultaneous parimutuel betting market, all(symmetric and asymmetric) Bayesian-Nash...

This paper examines finite parimutuel betting games with asymmetric information, with particular attention to differences between sequential and simultaneous settings, and betweenfully rational and myopic ("price taking") behavior. In the simultaneous parimutuel market,all (symmetric and...
