We created an economics profession which believed that [previous theoretical perspectives] had been “proved wrong”; whereas all that had really happened was that those things proved hard to model in terms of perfectly rational maximizing agents.I've written this before, but it's worth repeating: Paul Krugman is a sociologist in an economist skin. Molt on, my friend; molt on!
