To understand cooperative behaviour in social-dilemma experiments, we need to understand the game participants play not only in monetary but in preference terms. Does a Nash-prediction based on participants’ actual preferences describe their behaviour in a public-good experiment well? And if...

Models of evolutionary game theory have shown that punishment may be an adaptive behaviour in environments characterised by a social-dilemma situation. Experimental evidence closely corresponds to this finding but questions the cooperation-enhancing effect of punishment if players are allowed to...

Aggregate behavior in two-player hide-and-seek games deviates systematically from the mixed-strategy equilibrium prediction of assigning all actions equal probabilities (Rubinstein and Tversky, 1993, Rubinstein et al., 1996, Rubinstein, 1999). As Crawford and Iriberri (2007) point out, this...

Crawford and Iriberri (AER, 2007) show how a level-k model can be based on salience to explain behaviour in games with distinctive action labels, taking hide-and-seek games as an example. This study presents four dierent experiments designed to measure salience. When based on any of these...

In Geng, Weiss, and Wolff(2011), we pointed to the possibility that a voting mechanism may create or strengthen an entitlement effect in political-power holders relative to a random-appointment mechanism. This comment documents that such an effect, if it exists, is not robust.

Considerable experimental evidence shows that although costly peer-punishment enhances cooperation in repeated public-good games, heavy punishment in early rounds leads to average period payoffs below the non-cooperative equilibrium benchmark. In an environment where past payoffs determine...

Carpenter and Matthews (2009) examine the cooperation norms determining people's punishment behavior in a social-dilemma game. Their findings are striking: absolute norms outperform the relative norms commonly regarded as the determinants of punishment. Using multiple punishment stages and...
