Matt Klein is a columnist for the Financial Times and blogger at FT Alphaville. Today, he joins the show to discuss his work on the Eurozone, optimal currency areas, and safe assets. David and Matt examine the monetary policy problems and debt burdens facing the Eurozone area and Greece, in particular. They also chat about the possibility of the United States becoming less of an optimal currency, which would make Fed policy more challenging.
