What is this thing called happiness?

Abstract

Concern for one’s “reputation” has been introduced in recent game theory enabling theorists to demonstrate the rationality of cooperative behavior in certain contexts. And these impressive results have been generalized to a variety of situations studied by students of business and business ethicists. But it is not clear that the notion of reputation employed has much explanatory power once one sees what is meant. I also suggest that there may be some larger lessons about the notion of rationality used by decision theorists.
