Criminal Deterrence Research at the Outset of the Twenty-First Century

TLDR: In this article, the authors assess the effectiveness of policy options for deterring crime and find that some policies that are effective in preventing crime in the short term may be ineffective or even criminogenic in the long run because they may erode the foundation of the deterrent effect-fear of stigmatization.

Abstract: Evidence for a substantial deterrent effect is much firmer than it was two decades ago. However, large gaps in knowledge on the links between policy actions and behavior make it difficult to assess the effectiveness of policy options for deterring crime. There are four major impediments. First, analyses must estimate not only short-term consequences but also calibrate long-term effects. Some policies that are effective in preventing crime in the short term may be ineffective or even criminogenic in the long run because they may erode the foundation of the deterrent effect-fear of stigmatization. Second, knowledge about the relationship of sanction risk perceptions to policy is virtually nonexistent; such knowledge would be invaluable in designing effective crime-deterrent policies. Third, estimates of deterrent effects based on data from multiple governmental units measure a policy's average effectiveness across unit. It is important to understand better the sources of variation in response across place a...
