RT Conference Proceedings T1 A License to free ride? Centrality, authority & ostracism in social-dilemma networks A1 Ramalingam, Abhijit A1 Van Leeuwen, Boris A1 Rojo Arjona, David A1 Schram, Arthur K1 Juegos, Teoría de AB We investigate the effects of power derived from centrality and authority on contributions in repeated social dilemma settings. Groups of five players play VCMgames on a fixed network, where there is one central player that connects two pairs of periphery players. Centrality is defined by the position that a player has in thenetwork. Central players are vital to maintain a connected network and therefore havemore power than players in the periphery. In some treatments the VCM is convertedto a multi-player trust game, where the central player is given more power by givingher the authority to allocate the joint funds raised through contributions. Our resultsshow that power matters; both centrality and authority yield more free riding than isobserved for players in the periphery. This goes unpunished. Powerful players are notexcluded more than others except in extreme cases. We conclude that power providesa license to free ride.
