This article reviews the empirical evidence on college student cheating and places it in a context that combines economic theories of benefit/cost analysis and unobservable behavior with social network analysis of how widespread rule breaking can develop in an organization. The implications are that students cheat because the benefit/cost trade-off favors cheating; that the problem of unobservable behavior can be substantially mitigated by promoting academic integrity as the social norm; and that many factors that have contributed to the development of more and stronger relationships between college students have helped to promote cheating. The article makes ten specific recommendations for educators. (Contains 7 notes.)
