Studies have shown that there are differences in cooperative behavior across countries. Furthermore, differences in the use and the reaction on the introduction of a norm enforcement mechanism have been documented in cross-cultural studies, recently. We present data which prove that stark...

The effects of stake size on cooperation and punishment are investigated using a public goods experiment. We find that an increase in stake size does neither significantly affect cooperation nor the level of punishment.

Journal rankings are important for evaluating research output, for academic promotions, and for allocating funds. Examining the assignment of economics journals to different quartiles of citation-based rankings, the authors found that about 60% of journals remain in the same quartile and about...

We use a laboratory experiment to examine whether and to what extent other-regarding preferences (efficiency, inequality aversion and maximin concerns) of team managers influence their management style in choice under risk. We find that managers who prefer efficiency are more likely to exercise...

This paper addresses the institutional concentration of authors in 15 top economics journals from 1977 to 1997. The concentration of authors' PhD affiliations is substantially higher than the concentration of authors' current affiliations. Relating input indicators, such as population, number of...

Arad and Rubinstein (2012a) have designed a novel game to study level-. k reasoning experimentally. Just like them, we find that the depth of reasoning is very limited and clearly different from that in equilibrium play. We show that such behavior is even robust to repetitions; hence there is,...

Many tournaments are plagued by sabotage among competitors. Typically, sabotage is welfare-reducing, but from an individual’s perspective an attractive alternative to exerting positive effort. Yet, given its illegal and often immoral nature, sabotage is typically hidden, making it difficult to...
