Mar 01, Ryan B rated it liked it Skin in the Game is at the same time thought-provoking and original but also contradictory and sometimes absurd. But why does he insist on presenting his views in this way?

The communication of his ideas, often profound, does not require a mean-spirited or condescending tone. One wonders why Taleb cannot just present his ideas without the incessant personal attacks and condescension.

His overall philosophy appears to be self-refuting.

As far as I can tell, Skin in the Game is a work of philosophy, an intellectual exercise that argues against the value of intellectual exercise. The upside for him is book sales with little to no downside risk, so by using his own logic we should conclude to not trust him.

Except that Taleb uses economic theories to frame his thinking.

The Implication of the Efficient Market Hypothesis

The Tragedy of the Commons, something Taleb discusses in his book, was developed by the economist William Forster Lloyd in his armchair. Taleb obsesses about the superiority of practice over academics and theory.

This is a questionable proposition.

The efficient market hypothesis (EMH) is an important assumption in finance. What are the various forms of the EMH? Does the EMH in any of its forms make . The EMH topic fascinates the researcher, and relating the EMH concept to corporate finance through examination of markets can help improve the efficiencies within corporate world as well as increase investors wealth and decision taking. In finance, the efficient market hypothesis (EMH) asserts that financial markets are "informationally efficient", or that prices on traded assets, e.g., stocks, bonds, or property, already reflect all known information and therefore are unbiased in the sense that they reflect the collective beliefs of all investors about future prospects.

Very experienced, practical individuals sometimes perpetuate bad habits and fail to keep informed of the theories and academics that lead to better practice.

This point is completely lost on Taleb. Imagine a hypothetical survival machine is available for your use. By plugging yourself in, it will guarantee and maximize your life span and, on a social scale, maximizes reproduction.

The price is that the machine also inflicts a high degree of pain and cuts you off from contact with other people.

According to the logic of Taleb, the rational thing to do would be to plug into this machine. Of course, no one would volunteer to do this because survival is not what motivates rational behavior. Any rational agent would choose one year of pleasant life over years in the survival machine, because actions have value according to how they promote or are perceived to promote well-being or pleasure.

Taleb, using this more believable definition of rationality, could have used it to argue the same points, namely how religious belief cannot be called irrational if it promotes well-being, which includes psychological well-being and survival but not survival alone. When not being demeaning or taking extreme positions, Taleb writes about some of the most original, thought-provoking, and profound ideas.

And even when you find yourself disagreeing with him, he makes you think.

For this reason alone, the book is worth checking out. And his idea that you should have to pay some kind of penalty for decisions that negatively impact others—risk sharing vs. Of course, these ideas would be easier to swallow if presented with a little more humility, but I suppose we should know what to expect from Taleb by now.

Ryan, you have composed a comprehensive, impressive analysis of the book. Certainly the best book review in GR I have ever read. Makes me wa Seconded. Makes me want to set my quill down and think more about what I read.

Another obvious example, he attacks Sam Harris and Richard Dawkins without specifically explaining his actual problem with them. Therefore following his own preaching he is acting with zero skin in the game as by not explaining his problem he is blocking any real kickback.

He is taking the upside of causing friction without having skin in the game of possibly being proven weak in his reasoning.Skin in the Game has 4, ratings and reviews.

The efficient market hypothesis by Fama (), Random Walk module by Makiel () and behaviour finance theories are directed related to this issue and form the theoretical foundations.

Section 1 will critically give the theoretical review based on the two schools of thought that are EMH and behaviour finance theories. Efficient Market Hypothesis efficiency can be divided into 3 different levels: Weak form level of efficiency Weak for level of efficiency indicate that the historical price of securities can be used to articulate the changes in the security prices.

these assumptions are domain assumptions i.e.; assumptions required to make a theory valid and in the absence of which the theory is no longer true. This strongly implies that EMH, and CAPM, just happens to fit the data by luck for certain ranges of price movement, but that in fact other factors.
