off-topic: historical query concerning the Internet bubble

[Andrew Odlyzko <odlyzko () umn edu>]

Apologies for intruding with this question, but I can't think
of any group that might have more concrete information relevant
to my current research.



Enclosed below is an announcement of a paper on technology bubbles.
It is based largely on the Internet bubble of a decade ago, and
concentrates on the "Internet traffic doubling every 100 days" tale.
As the paper shows, this myth was perceived in very different ways
by different people, and this by itself helps undermine the foundations
of much of modern economics and economic policy making.

To get a better understanding of the dynamics of that bubble, to assist
in the preparation of a book about that incident, I am soliciting 
information from anyone who was active in telecom during that period. 
I would particularly like to know what you and your colleagues estimated 
Internet traffic growth to be, and what your reaction was to the 
O'Dell/Sidgmore/WorldCom/UUNet myth.  If you were involved in the industry,
and never heard of it, that would be extremely useful to know, too.

Ideally, I would like concrete information, backed up by dates, and possibly
even emails, and a permission to quote this information.  However, I will
settle for more informal comments, and promise confidentiality to anyone
who requests it.

                             ABSTRACT

   Gullibility is the principal cause of bubbles.  Investors and the general 
public get snared by a "beautiful illusion" and throw caution to the wind. 
Attempts to identify and control bubbles are complicated by the fact that 
the authorities who might naturally be expected to take action have often 
(especially in recent years) been among the most gullible, and were 
cheerleaders for the exuberant behavior.  Hence what is needed is an 
objective measure of gullibility.

   This paper argues that it should be possible to develop such a measure. 
Examples demonstrate, contrary to the efficient market dogma, that in some 
manias, even top-level business and technology leaders do fall prey to 
collective hallucinations and become irrational in objective terms.  During 
the Internet bubble, for example, large classes of them first became unable 
to comprehend compound interest, and then lost even the ability to do simple 
arithmetic, to the point of not being able to distinguish 2 from 10.  This 
phenomenon, together with advances in analysis of social networks and related 
areas, points to possible ways to develop objective and quantitative tools 
for measuring gullibility and other aspects of human behavior implicated in 
bubbles.  It cannot be expected to infallibly detect all destructive bubbles, 
and may trigger false alarms, but it ought to alert observers to periods 
where collective investment behavior is becoming irrational.

   The proposed gullibility index might help in developing realistic economic 
models.  It should also assist in illuminating and guiding decision making.
