Supported Work for Ex-Addicts: An Exploration of Endogenous Tastes
通过人力资本模型和内生偏好模型，分析支持性工作项目对前吸毒者就业、犯罪和吸毒的影响，发现项目提高了部分人的收入（主要通过增加工时），减少了抢劫和毒品相关犯罪，但未降低复吸率。
The expected impact of Supported Work on former drug addicts' employment, crime, and drug use are derived from two models: the human capital model and a model of endogenous tastes. Empirically, Supported Work is found to increase the earnings of at least some ex-addicts, primarily due to increases in hours worked rather than wage rates. The program also reduced ex-addicts' crime, producing the greatest impact on the robbery and drug-related crimes and changing relationship between crime and employment. The program did not affect ex-addicts' recidivism to drugs. The pattern effects only partially supports the human capital model, and there is also some support for the model of endogenous tastes.
