A teoria do comércio interestelar

É por estas e outras que me orgulho de ser economista: Paul Krugman sobre a Teoria do Comércio Interestelar, em Economics: the final frontier - Paul Krugman - Op-Ed Columnist - New York Times Blog.

Ladies and gentlemen, I give you The Theory of Interstellar Trade."
