Emotional reaction to free-riding incites individuals to apply sanctions when they are available. The application of sanctions activates a “virtuous emotional circle” that accompanies cooperation. Emotionally ar...

Legume Sanctions and the Evolution of Symbiotic Cooperation by Rhizobia.

The legume-rhizobium symbiosis is an ideal model for studying the factors that limit the evolution of microbial mutualists into parasites. Legumes are unable to consistently recognize parasitic rhizobia that, once established inside plant cells, use plant resources for their own reproduction rather than for N2 fixation. Evolution of parasitism in rhizobia, driven partly by competition among mul...

When punishment fails: Research on sanctions, intentions and non-cooperation

People can become less cooperative when threatened with sanctions, and previous research suggests both "intentions" and incentives underlie this effect. We report data from an experiment aimed at determining the relative importance of intentions and incentives in producing non-cooperative behavior. Participants play a one-shot investment experiment in pairs. Investors send an amount to trustees...

Some of the more sophisticated work on economic coercion has fo...
