Both in the field and in the lab, participants frequently cooperate, despite the fact that the situation can be modelled as a simultaneous, symmetric prisoner's dilemma. This experiment manipulates the payoff in case both players defect, and explains the degree of cooperation by a combination of...

Globalisation can mean one of four things: a considerable degree of regulatory competition; a geographically relevant market transgressing national and regional borders; the transfer of significant regulatory power to supranational entities; the public perception that nation states have lost a...

The standard tool for analysing social dilemmas is game theory. They are reconstructed as prisoner dilemma games. This is helpful for understanding the incentive structure. Yet this analysis is based on the classic homo oeconomicus assumptions. In many real world dilemma situations, these...

Cooperation problems are at the heart of many everyday situations. In this paper, we propose a very simple and light-handed mechanism to sustain cooperation and test its performance in a rich laboratory environment. The mechanism moderates cooperation by controlling experiences, more...

From the perspective of competitors, competition may be modeled as a prisoner's dilemma. Setting the monopoly price is cooperation, undercutting is defection. Jointly, competitors are better off if both are faithful to a cartel. Individually, profit is highest if only the competitor(s) is (are)...

If two players of a simultaneous symmetric one-shot prisoner's dilemma hold standard prefer-ences, the fact that choosing the cooperative move imposes harm on a passive outsider is imma-terial. Yet if participants hold social preferences, one might think that they are reticent to impose harm on...

The European Commission is working on a revision of its Guidelines on Research and Development Agreements. On this occasion, this note surveys the existing experimental evidence. Experiments add a number of additional arguments to the normative assessment. R&D agreements have a much smaller...
