I can give a brief start. I don't know if Ian wants to jump in here at some point.
I don't think it's obvious to me that countries that advocated austerity did worse. I know Germany and Canada, for example, had the smallest increases in deficits on the order of 5% during the crisis compared to 10% in Britain and the U.S. Germany and Canada also advocated at a G7 meeting that we should be moving toward austerity first, and I think, overall, Germany and Canada did pretty well compared to certainly the United States and even Britain, although obviously they had a banking crisis and we didn't, so it's apples and oranges.
I think it's a bit simplistic to say that countries that undertook austerity during and after the crisis didn't fare as well.
