In this paper we analyze R&D collaboration networks in industries where firms are competitors in the product market. Firms' benefits from collaborations arise by sharing knowledge about a cost-reducing technology. By forming collaborations, however, firms also change their own competitive...

Using a laboratory experiment, we examine whether informal monetary sanctions can lead to better coordination in a repeated minimum effort coordination game. While most groups first experience inefficient coordination, the efficiency increases substantially after introducing an ex post...

In diesem Beitrag geht es um subjektive Gerechtigkeitsvorstellungen, nicht Gerechtigkeit an sich, da erstere im Gegensatz zu letzterer empirisch feststellbar und handlungswirksam sind. Allerdings müssen ihre Folgen nicht nur gute sein. Gerechtigkeitsvorstellungen können erstens die...

This paper asks whether population growth is conducive to the sustainability of cooperation. A simple model is developed in which farmers who live around a circular lake engage in trade with their adjacent neighbors. The payoffs from this activity are governed by a prisoner's dilemma rule of...

Die vorliegende Arbeit untersucht das Fairnessverhalten von Studierenden unter-schiedlicher Studienrichtung. Hierzu wurden 289 Studierende der Ernst-Abbe-Hochschule Jena vor zwei verschiedene Entscheidungssituationen gestellt. In diesem Befragungsexperiment mussten die Studierenden wählen, wie...

In dieser experimentellen Studie untersuchen wir das kooperative Verhalten von Offizieren (bzw. Offiziersanwärtern) der Bundeswehr. Dabei betrachten wir ihre Interaktionen sowohl untereinander als auch gegenüber zivilen Probanden. Unsere Kernhypothesen sind, dass sich die angehenden Offiziere...

This paper examines the reflexive interplay between individual decisions and social forces to analyze the evolution of cooperation in the presence of "multi-directedness", whereby people's preferences depend on their psychological motives. People have access to multiple, discrete motives....

This paper asks whether population growth is conducive to the sustainability of cooperation. A simple model is developed in which farmers who live around a circular lake engage in trade with their adjacent neighbors. The payoffs from this activity are governed by a prisoner's dilemma rule of...

Explaining the evolution and maintenance of cooperation among unrelated individuals is one of the fundamental problems in biology and the social sciences. Recent experimental evidence suggests that altruistic punishment is an important mechanism to maintain cooperation among humans. In this...
