Eso se pregunta
Paul Krugman en su blog y la respuesta no está nada clara, pero sugiere que quizás las bajadas de tipos de la Fed que se avecinan no tengan el efecto deseado.
So: is it even possible for the Fed to cut interest rates enough to create a renewed housing boom? (The Fed can cut the overnight rate all the way to zero, but even large changes in the overnight rate can have only modest effects on mortgage interest rates, if the market perceives those changes as temporary.) If it can’t, how much can the Fed really do to help the economy?
