Would that be "Nobel Laureate, Dr. Paul Krugman?"
Heh, not in 2003! :) And the "Dr." wasn't on his byline.
The Times Style Guide eschews honorifics.
He may not have been "Nobel Laureate, Dr. Paul Krugman" at that point, but I'm pretty sure he was already "former paid Enron economic adviser Paul Krugman" by then. A point that everyone who ever has to face off against him in public needs to remind their audience early and often.
