This paper examines the usefulness of Kalai (2020)’s measure of the viability of Nash equilibrium. We experimentally study a class of participation games, which differ in the number of players, the success threshold, and the payoff to not participating. We find that Kalai’s measure captures...

This paper reports the results of an experiment on information spillovers between groups. We find that a player who is a member of multiple groups aggregates infor- mation and serves as a conduit through which information from one group spills over to another. We also find that such players are...
