Bernanke the academic, now the Fed chairman, assures us that he's vigilantly watching the economic horizon for clues on Federal interest rate policy. I'm sure he's even passing out the book he authored to other governors to assist them in conducting Fed policy. Now you can buy it: Principles of Economics on sale for just $8. Yes $8. ($3.95 on Amazon for a nice used copy.) The original list price was $55.01. A haircut of 85%. No wonder Bernanke doesn't like markets! It discounts his books, and refuses to believe his forecasts. Maybe the emperor is naked.
