We experimentally disentangle two potential sources for endogenous social interactions effects. By comparing groups where the group norm is publicly observable with those where it is not we can measure the size of any endogenous observation effect. By comparing connected with disconnected groups...

Cyber attacks are a growing threat that undoubtedly cause significant loss to individuals. We know, however, surprisingly little about the true economic cost of such attacks. In this paper we estimate the value individuals put on their computer files by eliciting willingness to pay (WTP) and...

We explore the extent to which information about the social value orientation (SVO) of group members influences contributions to a public good. We compare four networks of information - empty, pair, star and complete. We find that information about SVO has a significant impact on contributions...

We investigate experimentally whether the extent of conditional cooperation in public good games depends on the marginal return to the public good and type of game. The marginal return is varied from 0.2 to 0.4 to 0.8. The "standard" game, in which three players contribute before a follower, is...

We investigate experimentally whether the endowment of potential contributors changes the success rate of providing threshold public goods. We find a U shaped relationship in which the success rate is relatively high when the endowment is either relatively small or large. We also find an...

We contrast and compare three ways of predicting efficiency in a forced contribution threshold public good game. The three alternatives are based on ordinal potential, quantal response and impulse balance theory. We report an experiment designed to test the respective predictions and find that...
