经济学没有认识论。以经济学模式行为的行为者经由假定而获得知识。即使当经济世界中存在不确定性的时候,经济学行为人仍然可能准确地知道那一不确定状态是怎样的。因此,经济学者似乎不会在是什么使得法律成为要求服从的一种充分“明确的”指令这样一些哲学和心理学的问题上,增进我们的理解。然而,基于某种反思并带着其特有的自以为是,经济学者可能会找到一种做出贡献的方式,即主要通过利用其陈旧的经济框架提出以下问题:不同类型的法律规则是如何影响人们的行为的?一项特定的法律规则或原则的成本和收益如何? Economics does not have epistemology. The actors who behave in an economic model acquire knowledge via assumptions. Even when there is uncertainty in the economic world, economists may still be able to accurately know what that uncertainty is like. Therefore, economists do not seem to be able to enhance our understanding of philosophical and psychological issues that make law a sufficiently “explicit” directive to obey. However, based on some reflection and with its own self-righteousness, economists may find a way to make a contribution by using the old economic framework to ask the following questions: How different types of legal rules affect people What are the costs and benefits of behaving? A particular legal rule or principle?
