Sequel to Liebowitz's Comment on the Oberholzer-Gee and Strumpf Paper on Filesharing

Abstract

Through a stroke of luck, a referee report in the review process at the JPE has been positively identified as the Oberholzer-Gee/Strumpf (O/S) response to my earlier comment. Regardless of the response's provenance, what counts is whether it solidly refuted my comment. This 'sequel' analyzes the O/S response. The O/S response only deals with four of the nine points discussed in my comment, leaving the five remaining critiques unchallenged. The conclusion of my review is that the O/S response fails as a defense of these four points and contains many of the same types of errors that marred their original paper. This sequel also discusses the history of this dispute including O/S' various reasons for not making their data available. Finally, this sequel provides full documentation on the JPE's decision not to publish the comment.
