Headline Inflation Spikes Sharply in
August The all-items consumer price index rose at an annual rate of 7.44% in August, the highest monthly rate of inflation in over three years. It was the first time since March that headline inflation had exceeded an annual rate of 1% Nearly all of the increase was attributable to a jump in gasoline prices, which jumped by 9% in the month of August alone. The year-on- year change in gasoline prices was just 1.8% Posted Sept. 15, 2012 on Ed Dolan’s Econ Blog http://dolanecon.blogspot.com

Core Inflation Fell in August
Food and energy prices are volatile and usually account for much of the month-to-month change in the CPI Their effect can be removed by taking food and energy out of the CPI. The result is called the core inflation rate. The rate of core inflation for August, stated as an annual rate, was 0.6%, about half of the July rate.

Trimmed Mean Inflation Also Remains
Low Another way to remove volatility is the 16% trimmed mean CPI published by the Federal Reserve Bank of Cleveland. It removes the 8% of prices that increase most and the 8% that increase least in each month (or decrease most), whatever they are The 16 percent trimmed mean CPI slowed to an annual rate of 2 percent in August Posted Sept. 15, 2012 on Ed Dolan’s Econ Blog http://dolanecon.blogspot.com

Which Measure is Best? The
CPI for all items gives the most accurate measure of current changes in the cost of living Economists at the Fed look closely at the core and trimmed mean CPIs to judge the effect of monetary policy on underlying inflationary trends The Fed considers inflation of about 2 percent to be consistent with prudent monetary policy.

The Longer Term Trend To
see longer term trends in inflation, it is useful to look at year- on-year changes, which compare each month’s price level with that of the same month in the year before All y-o-y measures of inflation rates slowed during the global recession, then rose again for most of 2011. The three measures shown here have moved steadily downward in 2012. All now below the Fed’s 2 percent target Posted Sept. 15, 2012 on Ed Dolan’s Econ Blog http://dolanecon.blogspot.com

Inflation and Quantitative Easing At
its September 2012 meeting, the Federal Open Market Committee of the Federal Reserve System voted to undertake a new round of expansionary monetary policy, known as quantitative easing. The Fed made that decision on the basis of low rates of inflation for core measures and related data from the GDP accounts The Fed’s decision came before the August CPI figures came out, but it is unlikely it would have been influenced by the one-month spike in headline inflation Posted Sept. 15, 2012 on Ed Dolan’s Econ Blog http://dolanecon.blogspot.com
