自西蒙获得 1978 年阿尔弗雷德·诺贝尔经济科学纪念奖以来，几十年来经济学界的一大悲剧是，他的思想在该学科中的应用要么很差，要么部分地未能正确体现他的愿景（就像旨在解决有限理性问题的主流模型一样）。在本章中，我首先试图理解这种情况，然后指出，数字革命使得经济学家比以往任何时候都更有必要接受西蒙的关键思想——不仅是他在有限理性面前的令人满意的选择观点，还有他对人工智能以及利他主义和系统设计的进化作用的思考。现代经济正在经历供给侧剧变，其核心在于可编程性和模块化问题。在需求方面，买家现在必须应对极其复杂的选择问题，其解决方案越来越依赖于社会投入。
One of the great tragedies in economics in the decades since Simon received the 1978 Alfred Nobel Memorial Prize in Economic Sciences is that the uptake of his ideas within the discipline has been either poor or in a partial manner that does not properly capture his vision (as with mainstream models purporting to address bounded rationality). In this chapter I begin by trying to make sense of this situation and then argue that the digital revolution is making it more imperative than ever that economists take up Simon’s key ideas — not merely his satisncing view of choice in the face of bounded rationality but also his thinking on artificial intelligence and the evolutionary roles of altruism and system design. The modern economy is undergoing supply side upheavals at the heart of which lie the issues of programmability and modularity. On the demand side, buyers now have to contend with choice problems of extraordinary complexity, whose solutions increasingly rely on social inputs.
