[A:] Great question!
In the article "Choosing a Graduate School in Economics I stated that I can't recommend particular schools. That's because I don't feel comfortable promoting programs I've never been a part of.
From what I've seen and heard, most macroeconomics courses in North American graduate schools use a neoclassical approach which stresses microeconomic foundations. You may not study much Friedman, per se, but you'll study models that owe a lot of debt to Friedman's work at the University of Chicago.
From what I've heard, most of the Ivey league schools still place a heavy influence on Keynesian macroeconomics, but I'm unsure of how true that is nowadays. So I'm asking for reader help with this question. Are you a graduate student in economics? If so, what school do you attend, and what types of model did you study? Please contact me using the feedback form.
