In my last post, I cited Jeff Frankel's keynote speech from a recent Bank of Canada-ECB workshop. He also pointed to the end of "Exorbitant Privilege" and "Dark Matter", and other arguments of American exceptionalism. I think we'll see resounding evidence of this in Friday's release of the US end-2008 Net International Investment Position (NIIP).
