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...

Motivated by recent research on survey data, we test the influence of the political regime on social norms under controlled laboratory conditions. Comparing solidarity behavior revealed by East and West Germans in 1995 and 2009, we find that East Germans persistently show much less solidarity...

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...

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...
