I have just posted a draft of a book review, Enforcing Law Online, forthcoming in the University of Chicago Law Review. It is a short review (17 pages) of the new book by Jack Goldsmith & Tim Wu, Who Controls the Internet? Illusions of a Borderless World.

  Here is the introduction:

  "Who Controls the Internet" is an entertaining and engaging book. Professors Goldsmith and Wu have written a short and accessible work that makes a straightforward and persuasive argument about the enforceability of law over the Internet. The book's brevity and anecdotal approach means that it overlooks a lot of detail; the dynamics of Internet regulation are more complicated than this short volume suggests. Whether this is a blessing or a curse depends on the reader's taste. It makes the book a fun read, but it also keeps the authors from grappling fully with the dynamics of the topics they cover. Either way, "Who Controls the Internet" is an important addition to the literature that deserves to be widely read.
  This review begins with a summary of the book, and next discusses the cyberutopian vision of the Internet that it targets. It then considers what seems to be the deeper question underlying the book: When can law successfully regulate the Internet? It suggests that the effectiveness of a legal regime designed to regulate Internet transactions will depend heavily on four factors: who the law regulates, the cost and political viability of enforcement strategies, how much compliance is needed for the law to achieve its goals, and which side is winning the technological arms race at any given time.

  Comments welcome, as always. Also, I'd be interested in reader feedback on the SSRN "stamp" that SSRN is now requiring on all new papers posted to SSRN. You can see it along the left-hand side of each page. SSRN says that they intend this at least in part as a service to readers, but that they may remove it if it annoys readers instead. I'd be interested to know if readers like the stamp, or would rather have SSRN remove it.
