Consumer Protection Laws: Violator Detection and Enforcement Strategy
提出一套评估消费者保护法效果的方法，包括识别违规者特征和制定低成本高效执法策略，通过短期集中执法和长期维护程序实现。
A methodology is proposed for both the assessment and enforcement of consumer protection laws and regulations. An assessment model is presented to determine the effect of a law (e.g., violation rate, characteristics and/or profile of violators) and then a cost efficient law enforcement strategy is described that is aimed at the violator population identified by the assessment model. This methodology consists of a short enforcement campaign, directed mainly against the violators, and is then followed by an inexpensive maintenance program. Data for the assessment model are collected based upon an interrupted stratified time series design where the stratification scheme is selected by satisfying a minimum variance criterion. The stratification rule may vary so that a dynamic representation of the changing characteristics of the violator population is obtained.
