EVOLUTION OF COMMUNITY DETERRENCE: EVIDENCE FROM THE NATIONAL HOCKEY LEAGUE

摘要

Community and specialized enforcement are recognized as important components of deterring antisocial behavior. To provide insights on the interplay between deterrence methods, we examine the empirical evolution of fighting and scoring in the National Hockey League using time series data. We identify structural changes that correlate with changes in player behavior and rules. In particular, we find that player behavior related to fighting changed 4 or 5 years prior to most rule changes aimed at reducing fighting. We conclude that the decline in fighting in hockey was more closely associated with a change in community rather than specialized deterrence methods. (JEL Z22, D71, L83)
