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...

We study ultimatum and dictator experiments where the first moverchooses the amount of money to be distributed between the playerswithin a given interval, knowing that her own share is fixed. Thus, thefirst mover is faced with scarcity, but not with the typical trade-off betweenher own and the...

Different evaluators typically disagree how to rank different candidates since theycare more or less for the various qualities of the candidates. It is assumed that allevaluators submit vector bids assigning a monetary bid for each possible rank order.The rules must specify for all possible...

The existing literature acknowledges that a mismatch between the experimenter'sand the subjects' models of an experimental task can adversely aect the interpretation ofdata from laboratory experiments. We discuss why the two common experimental designs(between-subjects and within-subjects) used...

We analyze the effects of introducing asymmetric information andexpectations in the investment game (Berg et al., 1995). In our experiment,only the trustee knows the size of the surplus. Subjects’expectations about each other’s behavior are also elicited. Our resultsshow that average payback...

We use a two-person public goods experiment to distinguish betweene±ciency and fairness as possible motivations for cooperative behavior.Asymmetric marginal per capita returns allow only the high-productivityplayer to increase group payo®s when contributing positive amounts....

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...

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...

We adopt an evolutionary approach to investigate whether and when condi-tional cooperation can explain the voluntary contribution phenomenon oftenobserved in public goods experiments and in real life. Formally, conditionalcooperation is captured by a regret parameter describing how much an...

We use a two-person linear voluntary contribution mechanism with stochastic marginal benefits from the public good to examine the effect of imperfect information on contributions levels. To assess prior risk attitudes, individual valuations of several risky prospects are elicited via a...
