Alan Meltzer points out that Milton Friedman never supported increasing inflation to reduce the unemployment rate. The exception is when there is deflation. As an honorary advisor to the Bank of Japan, Meltzer, says he advised Japan to buy long-term bonds in the 1990's to increase money growth until deflation ended. Meltzer says there is no sign of deflation now, and the Fed's claim that there is a risk of deflation is because it uses the CPI (consumer price index) as a measure of inflation, and the CPI shows substantially less inflation than other indicators such as the Personal consumption expenditure deflator. The CPI he says gives double the weight to housing prices according to Meltzer
