Su suggerimento di @duccio, da New York Times.

Paul Krugman scrive un pezzo sui limiti della crescita in risposta a Mark Buchanan, che su Bloomberg accusava gli economisti di non tenere in considerazione questo fattore nelle loro analisi.

A few days ago Mark Buchanan at Bloomberg published a piece titled “Economists are blind to the limits of growth” making the standard hard-science argument. And I do mean standard; not only does he make the usual blithe claims about what economists never think about; even his title is almost exactly the same as the classic (in the sense of classically foolish) Jay Forrester book that my old mentor, Bill Nordhaus, demolished so effectively forty years ago. Buchanan says that it's not possible to have something bigger — which is apparently what he thinks economic growth has to mean — without using more energy, and declares that “I have yet to see an economist present a coherent argument as to how humans will somehow break free from such physical constraints.”

Of course, he's never seen such a thing because he's never looked. But anyway, let me offer an example that I ran across when working on other issues.
