Specific versus General Enforcement of Law
构建模型比较特定执法（针对单一违法类型）与一般执法（如巡逻警察可抓捕多种违法者）的最优制裁水平，发现特定执法下所有违法都应受极端惩罚，而一般执法下惩罚应随危害程度递增。
Optimal enforcement of law is examined in a model with specific enforcement effort--effort devoted toward apprehending individuals who have committed a single type of harmful act--and general enforcement effort--effort devoted toward apprehending individuals who have committed any of a range of harmful acts (a police officer on patrol, for instance, is able to apprehend many types of violators of law). If enforcement effort is specific, optimal sanctions are extreme for all acts. If enforcement effort is general, however, optimal sanctions rise with the harmfulness of acts and reach the extreme only for the most harmful acts. Copyright 1991 by University of Chicago Press.
