Richard Thaler: “The Behavioralizing of Economics” | Talks at Google
Published on Dec 9, 2015
Economist Richard Thaler visited Google’s office in Cambridge, MA to discuss the topic “The Behaviorializing of Economics: Why Did It Take So Long?”.
The talk is an introduction to his book “
Misbehaving“. He points out that economic models are based on ideal entities he calls “econs”. But maybe economic choices are made by entities we might call “humans”.
Richard Thaler is an American economist and the Ralph and Dorothy Keller Distinguished Service Professor of Behavioral Science and Economics at the University of Chicago Booth School of Business. He is the coauthor of the best-selling book “
Nudge” with Cass R. Sunstein, and the author of “ Quasi Rational Economics“, “ The Winner’s Curse“, and “ Misbehaving: The Making of Behavorial Economics“.
Welcome to Talks at Google in Cambridge, Massachusetts.
Today it’s my great pleasure to introduce Richard Thaler.
Don’t get too comfortable while you’re enjoying your lunch,
because Dr. Thaler is here today to change the way you
think about economics.
In his newest book, “Misbehaving: The Making
of Behavioral Economics,” he shows we
wacky humans don’t, in fact, make the kind
of rational decisions that traditional economics has
assumed in creating its models.
At first, these deviations from the assumed norm
were dismissed, but now our miscalculations
and their effects are the subject of serious study.
The book couples recent discoveries
in psychology with a practical understanding of incentives
and market behavior to tell us how
to make smarter decisions in an increasingly complex world.

Thank you very much for having me.
The title I’ve chosen for the talk today
is “The Behavioralizing of Economics:
Why Did it Take So Long?”
And this will give you a little taste
of what the book is about.
So it seems reasonable to start with a definition of what
is behavioral economics.
And as one of my predecessors, Herb Simon, Nobel Prize winner,
wrote this– the phrase “behavioral economics” appears
A free book to anyone who knows what that word means.
It’s a redundant phrase.
And so Simon is right, that it does
seem to be a redundant phrase.
Why do we need the adjective “behavioral?”
What other kind of economics could there be?
And then he answers his own question.
The answer lies in the specific assumptions
about human behavior that are made
in neoclassical economic theory.
So that theory is based on the assumption
that agents in the economy optimize.
They choose the best thing all the time.
So the idea is that economists think that the world is
populated by people like Spock.
-My choice will be a logical one.
Cold-hearted, rationalizing optimizers.
And I entertain the possibility that there
are some Homer Simpsons around.
So how do they differ?
The people that populate economic models I call econs.
And they’re perfect calculators, rational expectations.
They have no self-control problems.
They never are on a diet, because they
eat just the right amount.
They never have hangovers, because they
drink the right amount.
And they’re complete jerks.
Humans are dumber, weaker willed, and nicer.
Here’s an illustration of the fact that they’re nicer.
This is a picture I took in Ithaca,
where I lived for many years teaching at Cornell.
A farmer puts this stand up.
This time of year, he was selling rhubarb.
And it’s an honor box.
You put in your money, and you take your rhubarb.
Notice there’s a box here, and it’s got a lock on it.
And I think the farmer has just the right model
of human nature, which is there are enough honest people
that it’s worthwhile for him to put the corn or rhubarb out
there and enough people will put money in the box for him
to be willing to do that.
But if he left all the money out on a plate,
somebody would steal it.
When I first started teaching, I had the following problem.
I gave an exam, and the students got mad at me.
