The key element of models of contest is the Contest Success Function (CSF) which specifies the winning probabilities of agents. We provide an axiomatization of two parametric families of CSF’s. In the first, the winning probability of each agent depends on the investments and a vector of...

The key element of models of contest is the Contest Success Function (CSF) which specifies the winning probabilities of agents. The existing axiomatizations of CSFs assume that contestants can make only one type of investment. This paper generalizes these axiomatizations to the case where each...

In Amartya Sen's capability approach, policy makers can focus on different levels to influence the well-being of a society. We argue that improving capability to function as well as absolute levels of functioning achievement should be complemented by attention given to improving individuals'...

In case of digital goods such like music, intellectual property rights are typically not exerted by the creators (artists) but by intermediaries. Their profits, and therefore also the income of the artists, are endangered by copyright infringements (piracy). It is well known from static welfare...

Bounded rationality questions backward induction, which however, does not exclude such reasoning when anticipation is easy. In our stochastic (alternating offer) bargaining experiment, there is a certain first-period pie and a known finite deadline. What is uncertain (except for the final...

We analyse pricing, effort and tipping decisions in the online service "Google Answers" While users set a price for the answer to their question ex ante, they can additionally give a tip to the researcher ex post. In line with the related experimental literature we find evidence that tipping is...

The paper analyses the payment behaviour of customers of the online music label Magnatune. Customers may pay what they want for albums, as long as the payment is within a given price range ($5-$18). Magnatune’s comprehensive pre-purchase access facilitates music discovery and allows an...

Does geographic or (perceived) social distance between subjects signi?cantly affect proposer and responder behavior in ultimatum bargaining? To answer this question, subjects once play an ultimatum game with three players (proposer, responder, and dummy player) and asymmetric information (only...

In a two-person ï¬nitely repeated public goods experiment, we use intentions data to interpret individual behavior. Based on a random-utility model speciï¬cation, we develop a relationship between a player's beliefs about others' behavior and his contributions' plans, and use this...
