Using a simple OLG model where the research output of one generation provides inputs for the next, the paper explains how quality standards can become established in scientific competition. Researchers seek status, which they get if their results are used by the next generation. Quality is...

It is often conjectured that participatory decision making may increase acceptance even of unfavorable decisions. The present paper tests this conjecture in a three-person power-to-take game. Two takers decide which fraction of the responder's endowment to transfer to themselves; the responder...
