The Conduct of Economics: The Example of Fisher Body and General Motors RONALD COASE The University of Chicago Law School The University of Chicago Chicago, IL 60637 1. The Question The events leading to the acquisition of Fisher Body by General Motors (GM) were said by Benjamin Klein, in a paper published in 1998, to be “[p]erhaps the most extensively discussed example in the economic literature of a hold-up due to the presence of specific investments” (Klein, 1998, p. 241). Joel Trachtman, discussing opportunistic behavior in 1997, refers to the “classic example of Fisher Body and General Motors” (Trachtman, 1997, p. 521). More recently, in 2003, Douglas Baird noted that the merger of Fisher Body and GM had become “the paradigmatic example of vertical integration” (Baird, 2003, p. 24). Writing in 2004, Hideshi Itoh and Hodaka Morita refer to “the famous General Motors- Fisher Body example” (Itoh and Morita, 2004, p. 2). And there are many other references of a like nature. Certainly, as Oliver Williamson has correctly said, this example has been “widely used” (Williamson, 2002, p. 182). The problem with this widely used example is that the events, so minutely described, never happened. In this paper, I will consider what it is about the conduct of economics that led so many able economists to choose error rather than truth.
