Question: William Poole, president of the Federal Reserve Bank of St. Louis, recently suggested, "We may face more inflation pressure than currently shows up in the formal data. Statistical studies to detect pass-through from recent energy price increases have failed to show significant effects in U.S. price data. But stories about widespread pass-through are becoming increasingly common." Another Fed policymaker, Randall Kroszner, concluded, "We want to try to look where inflation is going. We don't want to look in the rearview mirror at what has happened to inflation."What policy making problems are these two Fed members alluding to? Why are these problems important?
