Crime Deterrence: Evidence From the London 2011 Riots
研究了2011年伦敦骚乱后严厉判决对犯罪率的威慑效应，发现骚乱区域及非骚乱区域的犯罪均显著下降，支持一般威慑理论。
Significant riots occurred in London in August 2011. The riots took place in highly localised geographical areas, with crime going up hugely in the affected sub-wards. The criminal justice response was to make sentencing for rioters much more severe. We show a significant drop in riot crimes across London in the six months after the riots, consistent with a deterrence effect from the tougher sentencing. More evidence of general deterrence comes from the observation that crime also fell in the post-riot aftermath in areas where rioting did not take place. © 2014 Royal Economic Society.
