A Short Note on the Size of the Dot-Com Bubble

Abstract

A surprisingly large amount of commentary today marks the beginning of the dot-com bubble of the late 1990s from either the Netscape Communications initial public offering of 1995 or Alan Greenspan's irrational exuberance speech of 1996. We believe that this is wrong: we see little sign that the aggregate U.S. stock market was in any way in a significant bubble until 1998 or so.
