It occurs when multiple people co-own a resource or property who have to grant each other permission in order to use or sell the resource. This study explores whether in an anticommons dilemma a participant’s feeling of ownership over a resource increases when he or she has to put effort into obtaining it. Half of the participants (Ntotal = 208) had to exert effort by doing an effort task in order to influence their Willingness To Accept (WTA) value, i.e. the amount of points they are willing to accept as payment in order to let the other co-owner use the resource. The participants also filled in a Psychological Ownership scale. Effort did not significantly influence psychological ownership, but psychological ownership did significantly influence WTA. There was no significant WTA difference between the (un)equal effort treatment conditions. The effects of effort are further analysed and discussed.Show less

Making participants of an anticommons game aware of externalities was expected to increase cooperation, by decreasing their willingnessto-accept (WTA) values, i.e. the amount they would be willing to accept in order to allow other individuals to make use of the resource. The results of the computer-based anticommons game (N = 167) did not support this hypothesis. However, the results did show, as predicted, that the more prosocial participants were, the more easily they allowed access to the resource by setting lower willingness-to-accept (WTA) values. Additionally, the hypothesized interaction effect between externalities awareness and Social Value Orientation (SVO) was not confirmed. Proselfs’ behavior did not change significantly more than prosocials’, after they got aware of the externalities. Finally, the negative effects of uncertainty in cooperation are discussed.Show less
