Replication of Conjoint Experiments on Legal Deterrence:Using the Drunk Driving Legislation in China as an Example
Effective legislation and enforcement in the area of road traffic safety has proved to reduce traffic injuries and fatalities in developed countries,yet such research has been limited in Chi-na,using driving-under-the-influence(DUI)as an example.Due to lack of high-quality data and pri-mary research on driver decisions,the deterrent effects of DUI laws in China remain unclear,despite the criminalization of drunk driving since May 2011 and associated enforcement efforts by the gov-ernment.Based on the classical theory of deterrence and recent advances in differential deterrence,this study as the third one in a series on legal deterrence,replicated a scenario-based conjoint experi-ment and established Hierarchical Bayes models for quantifying the unique effects of perceived cer-tainty,swiftness,and severity of DUI punishment,as well as detecting variations in risk percep-tions among general Chinese drivers.This replication study supported the usefulness of conjoint ex-periments for examining DUI decisions among drivers from different countries and groups,and helped for expanding the external validity of differential deterrence perspectives.It also provided conceptual and methodological insights into conducting experimental research and replication for the advancements of general public policy research in China.
