10 years of behavioral meaning: Thaler, Kahnman, Statman and Beyond


To mark Entrepreneurial investors’On the 10th anniversary, we have compiled previews of our coverage of the most important issues in finance and investment over the past decade.


Much of the philosophical architecture of modern finance – modern portfolio theory (MPT), capital asset value model (CAPM), efficient market estimation (EMH), etc. – depends on the underlying rationality of the overall human inputs that drive market dynamics. Markets contain fundamentally efficient, conventional theories, and perfectly investors want to maximize returns for a certain level of risk and make investment decisions accordingly.

But over the decades, the work of Herbert Simon, Daniel Kahnman, Amos Tversky, Robert J. Schiller, and Richard H. Thaler has challenged this orthodoxy among others, proving that the behavior of marketers and investors is much more vague than these theories.

No matter what investors do, these researchers have found that they are not following a “reasonable model” Homo economics Conceived by conventional means.

Of course, Kahnman, Schiller and company were rarely preaching in an empty cathedral. It was not particularly difficult to find evidence of collective human bias and irrationality in the financial field. But the global financial crisis (GFC) and what followed has made people more interested in behavioral money.

Why it is not difficult to see.

Although behavioral finance has helped highlight how modern finance sometimes fails to account for market events, it has yet to establish an integrated model that replaces it. Whether this will ever happen is an open question, but perhaps not a critical one: given the complexity of 21st century markets, it may be deliberate to think that a theoretical framework will ever cover the full breadth of market activity. But very rarely, as this collection shows, critical insights are gained by looking at conventional meanings through a behavioral lens.
