We examine how communication affects cooperation with the help of seven standard public goods experiments that only differ with respect to the medium of pre-play communication. Our treatments include bi-directional and unidirectional communication via (mostly electronic) auditory and/or visual...

In experimental bargaining with incomplete information, we vary the information distribution (symmetric and asymmetric), the direction of electronic pre-play communication (no, one-way, and two-way), and the electronic communication medium (email and video) Bargaining out-comes are influenced by...

Using data from laboratory experiments, we find that East Germans show consistently less solidarity than West Germans; there has been no convergence in the 20years after the reunification. While it has recently been estimated that political values converge 20 to 40years after the reunification...

We report on an experiment that uses a simple dilemma game to compare two characterizations of reciprocal behavior, differing on whether it is necesary to account for intentions in order to accurately predict and measure reciprocal actions. The design of the experiment allows us to study both...
