I bet not many of my readers can't wait till
the next book on economics comes out. Well, rarely having any interest myself
in such books, I have been quite
surprised by the extent to which two recent books from high priests of the
dismal science held my attention.
The first book I read was Dan Ariely’s
Predictably Irrational: The Hidden Forces That Shape Our Decisions. Ariely is a
pioneer thinker in the new branch of economics called “behavioral economics.”
Amazingly, over 235 years after Adam Smith famously claimed that the movement
of markets was caused by an “invisible hand” that reflected people’s rational
decisions taken on their own behalf, mainstream economics mainstream economists
are beginning to suspect that the “rational” part of people’s decisions has
been overplayed.
Dan Kenneth Arrow, Nobel Prize laureate in
economics commented, “"Dan Ariely's ingenious experiments explore deeply
how our economic behavior is influenced by irrational forces and social norms.
In a charmingly informal style that makes it accessible to a wide audience,
Predictably Irrational provides a standing criticism to the explanatory power
of rational egotistic choice."
I next read George Akerlof and Robert
Shiller’s Animal Spirits: How Human Psychology Drives the Economy and Why It
Matters for Global Capitalism. Akerlof is another Nobel laureate in economics.
Shiller is a prominent Yale economist and the Shiller of the widely followed
Case-Shiller Home Price Index. Akerlof and Shiller honor John Maynard Keynes,
one of the most influential economists in modern times whose 1936 magnum opus,
General Theory of Employment, Interest and Money, by titling their book after
Keynes term to signify irrational behavior in the marketplace, “animal
spirits.”
I was fascinated to learn that when
mainstream economists took to Keynesian economics they conveniently left out
Keynes’ thinking about how rational behavior was not as prominent in the
marketplace as classical economics held. It seems that mainstream economists
have a left brain view of the world, one in which everything that happens
ultimately has a predictable cause. The idea that some things just happen is an
anathema to left brain constructs of reality.
But the esteemed John Maynard Keynes knew
that the Newtonian-inspired idea that left brain based reason underlies the
comings and goings of markets was wrong-minded in its exclusivity. In the first
place, were all human behavior predictable the case would be closed on the
ancient quandary of philosophers about whether or not free will exists. The
notion that determinism shapes human, hence market behavior forecloses the
possibility of free will.
Sadly, the denizens of the marketing
profession have by and large had the same mechanistic view of markets. Rather
than become in-depth students of human behavior, most marketers have depended
on anecdotal and statistical renderings of behavior. To the extent that
behavioral science has been part of marketing tradition, it has been pretty
much focused on social psychology, a field that is not very concerned with
individual behavior independent of social contexts.
But a new dawn appears on the horizon – in
marketing as well as in economics. As behavioral economics is beginning to chip
away at flawed assumptions about markets from an economic perspective,
behavioral marketing is doing the same from a marketing perspective. At long
last there is growing recognition among marketers that human behavior cannot be
totally reduced to numbers.
Animal Spirits does a superb job of
undercutting economists traditional obeisance to numbers – to the reduction of
market forces including human behavior to mere statistical constructs. For that
reason, I heartily recommend the book (as well as Ariely’s Predictably Irrational)
to marketers as well as to all others involved in any aspect of business. Few
of us will not be able to read Predictably Irrational without seeing ourselves
in some of the experiments Ariely has conducted that show how de minimus the
role of rational behavior is in our marketplace behavior.
And aside from supporting Ariely’s thesis,
Animal Spirits tells why, as nothing else I’ve read does, the Financial Crash
of 2008 occurred. Contrary to the view of many it was not due so much to
regulatory failures and greed in corporate executive suites as to the failure
of analysts and other investment p
Do yourself a very large favor and get both
of these books. You'll gain a better understanding of why economists and
markets get it wrong so often.
