Kevin Warsh, a distinguished visiting fellow at the Hoover Institution and a lecturer at the Stanford Graduate School of Business, said that Bernanke must be very worried about the economy based on the Fed’s aggressive actions six weeks ago. Warsh is not impressed with the efficacy of quantitative easing or convinced that it is the right medicine, at the right time, for the right problems but rather that the Fed is trying to get the economy going in the right direction without help from Congress or the president.
