ECIN Replication Package for "Aggregate and Individual Effects of Information in a Coordination (Traffic) Game"

Using an existing coordination (traffic) experiment, we investigate information’seffect on traffic congestion when subjects already have a history of past play. Incontrast to previous studies, our interventions neither alter aggregate nor individualpayoffs. A second study isolates individual-subject response to information using afixed distribution of past subjects. We find information alters subject play: subjectsswitch roads more often and receive higher payoffs conditional on switching roads.Because switching reduces payoffs unconditionally, information does not generallyimprove payoffs overall. Only subjects that receive information upon starting thegame appear to increase their payoffs due to the information treatment.
