The Effect of Employment Frictions on Crime
研究发现刑满释放人员平均需6个月找到工作，失业者再入狱速度是就业者的两倍；将失业期缩短3个月可使犯罪和累犯率降低5%以上。
This article provides estimates on how long it takes for released inmates to find a job and, when they find a job, how less likely they are to be incarcerated. An on-the-job search model with crime is used to model criminal behavior, derive the estimation method, and analyze policies including a job placement program. The results show that the unemployed are incarcerated twice as fast as the employed and take on average 6 months to find a job. The article demonstrates that reducing the average unemployment spell of previously incarcerated criminals by 3 months reduces crime and recidivism by more than 5%.
