This paper provides a new way to identify conditional cooperationin a real-time version of the standard voluntary contribution mechanism. Ourapproach avoids most drawbacks of the traditional procedures because it relieson endogenous cycle lengths, which are defined by the number of contributors...

Absentmindedness is a special case of imperfect recall which according to Piccione and Rubinstein (1997a) leads to time inconsistencies. Aumann, Hart and Perry (1997a) question their argument and show how dynamic inconsistencies can be resolved. The present paper explores this issue from a...

We report on an experiment using video technology to manipulate pre-play communication protocols in the lab and to study purely social effects of communication on donations and discrimination between potential receivers. The experimental design eliminates strategic factors by allowing two...

It is commonly accepted that face-to-face communication inducescooperation. The experiment disentangles communication and socialeffect (replication of Roth, 1995) and examines the components of thesocial effect with the help of unilateral communication. Results suggestthat separate processes,...
