Creating and Enforcing Norms, with Special Reference to Sanctions

Two central puzzles about social norms are how they are enforced and how they are created or modified. The sanctions for the violation of a norm can be categorized as automatic, guilt, shame, informational, bilateral costly, and multilateral costly. The choice of sanction is related to problems in creating and modifying norms.

We conclude that the difficulty of predicting the effect of such action limits its feasible scope
