THE BECKER PARADOX AND TYPE I VERSUS TYPE II ERRORS IN THE ECONOMICS OF CRIME*
构建了一个允许无辜者被定罪的司法程序一般均衡模型,利用中位选民定理使司法程序内生化,成功解释了死刑罕见和证明标准差异这两个现实观察。
Two real‐world observations are not easily replicated in models of crime. First, although capital punishment is optimal in the standard Becker model, it is rarely observed in the real world. Second, criminal procedure and the evaluation of evidence vary across societies and historical periods, the standard of proof being sometimes very high and sometimes quite low. In this article, we develop a general equilibrium model of judicial procedure allowing for innocent persons being convicted. We show that the median voter theorem applies to this model, making judicial procedure endogenous. So formulated, the model can replicate both empirical observations.
