Joseph A. LaVorgna, the Chief US Economist of Deutsche Bank, asks the question: "Can Inflation Go Up but the Fed Stay Measured?" He answers “yes,” because the inflation measure that Greenspan favors is focused on the core PCE deflator.

LaVorgna argues the core PCE is an implicit index — its weights change based on changes in consumer buying patterns. When prices rise, consumers tend to find lower priced substitutes and these substitutions help keep inflation down.
This is quite revealing of economists in general. Somehow, he omits to mention what one substitutes for gasoline, heating oil, milk, college or health care.
