Some more interesting comments from Bork's past writings: These come from "The Role of the Courts in Applying Economics," 54 Antitrust L.J. 21, 25 (1985). This rather short article appears to be from a symposium called "Antitrust in Transition.""Fred [Rowe, one of the other participants in the symposium, I assume--GRL] refers to the oligopoly model, which dominated antitrust for a while; then what he calls the efficiency model, which has now come into dominance; and finally to the learning curve model. In fact, the oligopoly model and the learning curve model are merely particular explanations of how things work that are within the efficiency model. . . . All of these things, all of the models or theories we are talking about, are simply stages in the intellectual evolution of what Fred calls the efficiency model. Wouldn't it be something if it turned out that the "network externalities" and "path dependency" models were also "simply stages in the intellectual evolution of what Fred calls the efficiency model"? And, in fact, I've started delving into some of the literature on network externalities, trying to get a handle on it, and have come up with the following tantalizing tidbit:"Markets exhibiting network externalities can fail, in that the unregulated outcome produces less total surplus than is possible. Indeed, recognizing that 'externality' is commonly understood to denote market failure. . . . This, from Lopatka & Page, "Posner's Program for the Antitrust Division: A Twenty Five Year Perspective," 48 SMU L. Rev. 1713, 1739 (1995). Now, there's a boatload of literature out there, and by no stretch of the imagination do I understand this stuff yet. But, it sure would be interesting to know what Bork's opinion is about these new-fangled theories called "network externalities" and "path dependency." I have a sneaking, growing suspicion that the answer just might surprise us.
