The topic at hand: in the case of
a legal mind like Richard Posner
argument is raised to an art form:
Admire the cavalcade of

KRUGMAN_INCLINED
Back to Posner's Grand Critique of Paul Krugman,
published in the reflexive "Public Intellectuals: Pay no attention
A Study in Decline". to these cryptic
notations...
On p.101-3, there's a discussion of IMG_7121.JPG
something Paul Krugman was saying IMG_7120.JPG
about amazon.com and the on-line
price discrimination.
It's a good idea to check with the

As usual, Paul Krugman's exposition is
admirably brief and clear, and it's
hardly worth the effort of summarizing,
but I'll give it a try:
Amazon has been charging different
prices of different customers for
the same products (movies).
Amazon insists that this was just
some sort of experiment in random
pricing, and denies it was targeted
against different users.
However, it's easy to imagine Amazon
or a company like Amazon doing this,
using it's knowledge of past
purchases to predict what a customer Before we lose track of
will be willing to pay in the future. what's actually important
here:

they are".
He then closes with a suggestion
that this practice may already
be illegal, pointing at the
Robinson-Patman Act.
Posner in his critique of all this
says that Krugman was reading the
Robinson-Patman act wrong (it applies
only to distributors), and goes on to
insist that there's nothing at all
wrong with Amazon using targeted
pricing--
There are two things that are striking
about Posner's representation of what
Krugman was saying.
One is very peculiar: from Posner,
you get the impression that Amazon This seems odd (to me),
definitely does this, but Krugman because I had the impression
made clear it was just a suspicion that Posner wanted to
that they were doing it. defend Amazon.

The other is that Posner ever so
slightly distorts Krugman's claim
about the Robinson-Patman act, to
make it sound like a much bigger gaff.
Here's Krugman:
"In fact, dynamic pricing might already be
illegal. I'm no lawyer, but it looks to me as
if the Robinson-Patman Act, which outlaws
price discrimination across state lines
(though strictly speaking only if it hurts
competition), could be invoked to prevent
dynamic pricing. But it's a judgment call-- ..."
Here's Posner:
"He is wrong about the Robinson-Patman
Act. It does not outlaw price
discrimination; if it did, examples
that Krugman gives of commonplace,
unexceptional price discrimination in
the publishing industry, such as the By the way: I might be

very cautious.

In Posner's discussion of "discriminatory
pricing" (p. 103) he continually conflates
charging different prices for different
products (hardback vs. paperback) with
charging different prices of different
customers.
This is so transparently dumb with
a capital D, it makes one wonder
where his reputation for
"brilliance" comes from.
Paul Krugman doesn't have any
trouble seeing the difference,
and I suspect neither do the
rest of us:
"So publishers try to sort
customers indirectly. Most books
are offered first in hardcover,
then some time later in

"But in the world of e-commerce, give the people who paid a
such crude market segmentation premium the *feeling* that

for their money.
Here's a good example of
Posner's fighting style:
"The consumer who has to pay full
fare to travel to a funeral is Here, the freedom to set

his special need, and likewise "discrimination"...

Posner has stated that

given Krugman's suggestion

Got that? I realize it's

work than it's worth.
It's a way for Posner to
get in a free hit: he
distorts some text that

the position a little

Posner really is a
deluded intellectual

really thinks that

I strongly suspect that
it's an entirely cynical
maneuver, exploiting
the difficulty of

of scoring political
points.
