Recent bargaining experiments demonstrated an impact of anonymity and incomplete information on subjects' behavior. This has rekindled the question whether "fair" behavior is inspired by regard for others or is explained by external forces. To test for the importance of external pressure we...

In this experiment, we analyze whether price ceilings can have a collusive effect in laboratory markets. Our main interest is the focal-point hypothesis which says that a price ceiling may facilitate tacit collusion and lead to higher prices because it resolves a coordination problem inherent to...

We report results from standard minimum-effort experiments conducted in Copenhagen (Denmark). Our subjects frequently coordinate on the Pareto-efficient equilibrium even in groups of six. This is in stark contrast to the previous literature, as we show in a detailed analysis of experiments which...

Research in behavioral economics has recognized the importance of reciprocity in individual behavior. The debate is dominated by a focus on direct reciprocity. Motivated in a real-life situation in Argentina - the piqueteros (pickets) conflict - I use a three-player three-stage game in order to...

The theory of reciprocity is predicated on the assumption that people are willing to reward nice or kind acts and to punish unkind ones. This assumption raises the question as to how to define kindness. In this paper we offer a new definition of kindness that we call “blame-freeness.” Put...
