The beauty of cooperation

A previous post described the economics of beauty. Better-looking people tend to earn higher wages. A recent paper (Darai and Grätz, July 2012) finds that beauty increases the probabilities of cooperation. The authors argue:

. . . facing a facially attractive opponent increases cooperation significantly. Especially, in mixed-gender interactions males and females are more likely to cooperate with a facially attractive counterpart.
