This paper studies behavior in experiments with a linear voluntary contributions mechanism for public goods conducted in Japan, the Netherlands, Spain and the U.S.A. The same experimental design was used in the four countries. Our `contribution function' design allows us to obtain a view of...

Various models of individual motivations are confronted with evidence from different kinds of laboratory experiments.

This paper provides experimental evidence showing that indirect reciprocity may important in economic decision making and in the development of group norms. We study a `repeated helping game' with random pairing in large groups, with individuals equally divided between donors and recipients....
