Endogenous Group Formation in Experimental Contests

چکیده
Endogenous group formation in experimental contests* Luisa Herbst, Kai A. Konrad, and Florian Morath We study endogenous group formation in tournaments employing experimental threeplayer contests. We find that players in endogenously formed alliances cope better with the moral hazard problem in groups than players who are forced into an alliance. Also, players who are committed to expending effort above average choose to stand alone. If these players are forced to play in an alliance, they invest even more, whereas their co-players choose lower effort. Anticipation of this exploitation may explain their preference to stand alone. Wir untersuchen die endogene Bildung von Gruppen in Wettkämpfen in experimentellen Drei-Spieler-Wettbewerben. Es zeigt sich, dass Spieler in endogen gebildeten Allianzen besser mit dem ‚Moral Hazard‘-Problem in Gruppen zurechtkommen als Spieler, die in eine Allianz gezwungen werden. Außerdem entscheiden sich Spieler, die bereit sind, überdurchschnittlichen Einsatz zu leisten, allein zu agieren. Sind diese Spieler gezwungen in einer Allianz zu spielen, investieren sie sogar mehr, wogegen ihre Mitspieler ihren Einsatz reduzieren. Die Erwartung dieser „Ausbeutung“ ist eine mögliche Erklärung für ihre Präferenz allein zu agieren.

متن کاملIdentification of Intracellular Sources Responsible for Endogenous Reactive Oxygen Species Formation
The endogenous reactive oxygen species ("ROS") formation is associated with many pathologic states such as inflammatory diseases, neurodegenerative diseases, brain and heart ischemic injuries, cancer, and aging. The purpose of this study was to investigate the endogenous sources for "ROS" formation in intact isolated rat hepatocytes, in particular, peroxisomal oxidases, monoamine oxidase, xanth...

متن کاملA Survey of Experimental Research on Contests, All-Pay Auctions and Tournaments
Many economic, political and social environments can be described as contests in which agents exert costly efforts while competing over the distribution of a scarce resource. These environments have been studied using Tullock contests, all-pay auctions and rank-order tournaments. This survey provides a comprehensive review of experimental research on these three canonical contests. First, we re...
متن کاملExistence and uniqueness of equilibrium in Asymmetric Contests with endogenous Prizes
This paper considers contests in which the efforts of the players determine the value of the prize. Players may have different valuations of the prize and different abilities to convert expenditures to productive efforts. In addition, players may face different financial constraints. This paper presents a proof for the existence and uniqueness of a pure Nash equilibrium in asymmetric contests w...
