老师您好!行为金融学原版书中关于Prescriptive analysis有如下两段描述:描述(一)Prescriptive analysis is concerned with practical advice and tools that might help people achieve results more closely approximating those of normative analysis.描述(二)We can think of the traditional finance assumptions about behavior as normative, behavioral finance explanations of behaviors as descriptive, and efforts to use behavioral finance in practice as prescriptive.描述一结尾部分提到Prescriptive analysis的效果与接近传统的金融学范畴normative analysis。而描述二结尾部分提到这是行为金融学。前后矛盾
