John McCallum's IDEAS page.
Really, it's pretty impressive. 3 AER is good for most anyone. He's in the top 5% of all economists in a number of metrics, which is also good, especially for someone who hasn't been an academic since 1994 or so. I'd be quite happy with that CV in 25 years.
That being said, Dion took an academically higher ground on economic issues, and look where it got him. One wonders if the Liberal Party is willing to make a stab with another intellectual.
