α: calibrated so average coauthorship-adjusted count equals average raw count
In a laboratory setting, we investigate the effect of competition for the resources of team members with ‘divided loyalties’, and the role of such competition in overcoming the free-rider problem associated with the provision of team-level public goods. We find that competition alone creates ‘winners’ and ‘losers’. However, if groups have access to more information on the actions of team members, or are able to determine their membership through ostracism, they are more successful in attracting the ‘loyalties’ of team members. By eschewing the study of additional mechanisms that require external intervention or alterations of payoff functions, our work highlights the potential of implicit competition in promoting cooperation.
