关于经济学究竟是不是科学的争论从未停息,经济学的研究方法、模型推演甚至基本假定都曾经受到诟病。这些质疑的声音不仅来自其他领域的学者,也包括经济学家的自我批判。在各种争论中,经济学家对市场经济的观察越来越深入,经济学不断发展。为了尽可能让自己的经济学原理能像数学和物理一样放之四海而皆准,经济学家运用各种手段力图解决经济交易中无法量化的不确定因素。这些不确定因素在很大程度上源于人类自身的行为,是由交易者个人的偏好(心理选择)来决定的。经济学在发展中先是剔除偏好,然后对偏好严格界定,把偏好分类,对偏好模拟,将偏好定
The debate over whether economics is science or not has never stopped, and the methods of economic studies, model deductions, and even underlying assumptions have been criticized. The voices of these questions come not only from academics in other fields, but also from economists’ self-criticisms. In various debates, economists observe the market economy more and more in depth and economics continues to develop. In order to make their own economic principles as comprehensive as mathematics and physics, economists use various means to solve the unquantifiable uncertainties in economic transactions. These uncertainties are largely due to the behavior of human beings, which is determined by the trader’s personal preference (psychological choice). Economics in the development of the first is to eliminate the preference, and then the strict definition of preferences, the preference classification, preference simulation, the preference given
