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.
看得真是手不释卷。 还没看完。 讲了很多。 大概是讲: 情绪是理性的基础,人类把对之前环境适应的反应内化成了情绪,是理性,高效的。但一旦环境变了,这种原本适应环境的行为在新的条件下就非常不理智了。在市场上也是这样。 很难一下总结。 先记个例子吧 就是投资的人都知道...
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...

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。
评分作者不愧是男神,了解的面好广,最后回归于金融本身。就像作者最后一部分所说:金融不单单是赚钱的机器,金融是可以以别样的方式贡献社会的。这一点也是我所信奉的,读的好爽!
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
