Parimutuel betting markets are simplified financial markets, andcan thus provide a clearer view of pricing issues which are more complicatedelsewhere. Though empirical studies generally conclude thatthe parimutuel betting markets are surprisingly efficient, it is alsofound that for horses with...

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...

´This paper aims to analize the role of personal identity indecision making. To this end, it starts by reviewing criticallythe growing literature on economics and identity. Consideringthe ambiguities that the concept of social identity poses, our proposalfocuses on the concept of personal...

We experimentally examine how group identity affects trust behaviorin an investment game. In one treatment, group identity isinduced purely by minimal groups. In other treatments, group membersare additionally related by outcome interdependence establishedin a prior public goods game. Moving...

Two firms compete on a sales market as well as in hiring labor. The duopolists'sales levels depend on their workforce. There are two each of two typesof workers, mobile and immobile, with differing effort costs. An immobileworker's eort costs are lower when he is employed by the local firm,...

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 examine the effects of leading by example in voluntary contributionexperiments. Leadership is implemented by letting one group membercontribute to the public good before followers do. Such leadershipincreases contributions in comparison to the standard voluntary contributionmechanism,...

Theory absorption, a notion introduced by Morgenstern and Schwödiauer (1972)and further elaborated by Güth and Kliemt (2004), discusses the problem whether atheory can survive its own acceptance. Whereas this holds for strategic equilibria accordingto the assumptions on which they are based,...

In a stochastic duopoly market, sellers must form state-specific aspirationsexpressing how much they want to earn given their expectationsabout the other's behavior. We define individually and mutually satisficingsales behavior for given individual beliefs and aspiration profiles. In afirst...
