Half of all Americans have money in the stock market, yet economists can't agree on whether investors and markets are rational and efficient, as modern financial theory assumes, or irrational and inefficient, as behavioral economists believe--and as financial bubbles, crashes, and crises suggest. This is one of the biggest debates in economics and the value or futility of investment management and financial regulation hang on the outcome. In this groundbreaking book, Andrew Lo cuts through this debate with a new framework, the Adaptive Markets Hypothesis, in which rationality and irrationality coexist.
Drawing on psychology, evolutionary biology, neuroscience, artificial intelligence, and other fields, Adaptive Markets shows that the theory of market efficiency isn't wrong but merely incomplete. When markets are unstable, investors react instinctively, creating inefficiencies for others to exploit. Lo's new paradigm explains how financial evolution shapes behavior and markets at the speed of thought--a fact revealed by swings between stability and crisis, profit and loss, and innovation and regulation.
A fascinating intellectual journey filled with compelling stories, Adaptive Markets starts with the origins of market efficiency and its failures, turns to the foundations of investor behavior, and concludes with practical implications--including how hedge funds have become the Galapagos Islands of finance, what really happened in the 2008 meltdown, and how we might avoid future crises.
An ambitious new answer to fundamental questions in economics, Adaptive Markets is essential reading for anyone who wants to know how markets really work.
Andrew W. Lo is the Charles E. and Susan T. Harris Professor at the MIT Sloan School of Management and director of the MIT Laboratory for Financial Engineering. He is the author of Hedge Funds and the coauthor of A Non-Random Walk Down Wall Street and The Econometrics of Financial Markets (all Princeton). He is also the founder of AlphaSimplex Group, a quantitative investment management company based in Cambridge, Massachusetts.
作者是专业学者。全书是作者的专业理论的科普,内容涉及到心理学、进化论、金融等多个学科,几乎没有公式,有一些专业的图表。篇幅较长,有43万字,正文355页,注释与引用60页。信息浓度比较高。在经管类畅销书中算是比较烧脑的作品了。 作者在学术界提出了“适应性市场假说”...
评分人类实时形成的贴现率曲线在一张图上的形状类似于双曲线——短期内非常高,在长期内非常平坦——因此被称为双曲贴现。 尤金·法玛有一个聪明的方法来避免双曲贴现陷阱。当法码被邀请演讲或参与一些商业活动时,他说了一个决定是否接受的简单规则:无论一件事情有多遥远,他会问...
评分尽管有诸多反例和不完美,有效市场假说在经济学中的老大地位还是没有被人轻易撼动。行为主人者攻击道:“有效市场假说中的“理性人”只能是存在于有效市场学派脑子里,现实世界根本没有人真正做到那样的理性,因为我们经常可以看到人们情绪失控下做出的糟糕决策,甚至我们自己...
评分书只看了一小半,看到了一些批评的声音,一些看法,权做讨论。 应该是基于我们传统的思维习惯,我们国人在看书的时候比较执迷于一套闭合的体系:逻辑严密,框架规整,也即偏好于一套自圆其说、充分自洽的理论,放之四海皆准,更优。因此很多读老外书的人常常大失所望,因为老外...

书很长,有点啰嗦。 没耐性的,就细读2, 6, 8 ,10,11,12 章,其实就可以了。
评分Andrew Lo把这些年来的研究堆叠在一起,说是created a new theroy。读完并未感觉豁然开朗。太多的铺陈以至于失却了主题。最后关于harvey lodish的故事打动人心。
评分预计六月中完成
评分抱负强大,嫁接进化论,神经学,行为学,和财务学,独创一套理论挑战其他在位理论。用力很猛,材料丰富,文笔一般。
评分投资确实需要这样的大一统理论研究,片面的学术研究几乎没有实用价值
