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.
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...
评分有人批评说经济学家们有一种“羡慕物理学”情结——沉迷于构建精确的数学模型,而不是去研究凌乱的现实世界。但一本新书认为,经济学家一直以来找错了对标的科学方向,他们本应该专注于生物学。 这一思想源自“行为经济学”学派。该学派指出,人类并不是某些模型所依赖的那种超...
评分因为朋友推荐,以及亚马逊上评价还算不错,于是找来看了看 挺失望的 如果你看过Misbehaving (行为经济学),A Man for All Markets (对冲基金), Skin in the Game (风险、非理性行为与survival的关系) 能从这本书里面学到的东西会非常的少 另一方面,书中花了相当篇幅介绍神经科...
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...
评分从西方经济学体系开始建立,市场就一直高傲地在那里,任各路专家、各路商人、各路散民研究探索,有时给人类很大自信,有时给人类重重一击。数字、逻辑、心理,对市场的解读似乎都对,又似乎都不准。有效市场和理性经济人假说都知道是绝对情况,但丝毫不影响经济学家们用模型算...
看完感觉就是观点少 扯了一堆没用的
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
评分陆陆续续读了很久。如果关于挤掉关于智人演化,行为偏差,风险管理基础知识介绍,金融危机简史,对未来社会发展进步展望的水分,这本书的中心思想可以20页篇幅内说完的。定位在后EMH概念的adaptive market介绍,科普读物罢了,谨慎过誉。
评分从生物学/心理学的角度阐述金融市场的历史演变,非常新颖与实用的角度。
评分差点就弃了,因为这个家伙说话实在太啰嗦!!但是,用盲人摸象的办法,以及不错的文笔,写了一个其实似是而非的理论
