交通肇事逃逸重复评价背后的经济学问题

从表面上看,交通肇事罪中对逃逸的重复评价是对刑法原理中的禁止重复评价原则的挑战。但通过剖析禁止重复评价原则背后的经济学原理就会发现,二者本质上是相暗合的。这是因为,禁止重复评价原则背后的经济逻辑就是要保证威慑的最优化,而禁止重复评价原则的适用是有条件的,其前提便是某类犯罪的特定情节或行为没有导致该类犯罪的抓获概率在一段时期内明显下降,刑罚的威慑效果也没有因为特定情节或行为的出现而受到削弱,否则,对某类犯罪的特定情节或行为进行重复评价便是必要的。

Economic Problem about Repeat Evaluation of Traffic Accident Escaption

On the surface,traffic crime repeating evaluation about escaption is a challenge of prohibiting repeated evaluation principles in criminal law. But by analyzing the economic principles behind prohibiting repeated evaluation principles will find that both of them are essentially coincident. Because the economic logic behind prohibiting repeated evaluation principles is the optimal deterrence,while the application of prohibiting repeated evaluation principles is conditional,its premise is that there is no specific plot or certain criminal acts leading to such a crime capture probability decrease over a period of time,there is no deterrent effect of penalties because of the emergence of a specific plot or behavior undermined,otherwise repeating evaluation the particular class of criminal plot or behavior is necessary.
