hamburger here, steak elsewhere

In my first post on venividiblogi I said this wouldn't be a deeply research blog, more just passing comments. And when I read stuff like this, I think I've taken the right path. I've admired Fred Argy's work for a while and this example just shows how a short but rigorous analysis of economic models can be so illuminating. What an absolute shame that such insightful and sensible stuff always gets buried by dross.
