The Inflation Update: August 2003
Stephen G. Cecchetti
16 September 2003

 

            This morning’s CPI report confirms inflation is relatively modest, at least for now.  While the all-items index rose 4% a.r. (annual rate) for the month, the big increase was largely attributable to the 2.7% increase in energy costs for the month – 38% at an annual rate.  Core measures of inflation were much more subdued with the CPI excluding food and energy was up only 1.2% a.r., while the Median CPI computed by the Federal Reserve Bank of Cleveland rose 2.8% a.r.. Both core measures are very near their recent 12-month averages – 1.3% for the CPI ex. food & energy, and 2.1% for the Median CPI. 

 

            Looking at the detail in the BLS release confirms that inflation is not an imminent threat to the economy and is unlikely to derail the FOMC’s (extremely) low-interest rate policy.  Core services (services less energy services) rose 2.1% a.r. for the month and is up 2.7% for the year ending August 2003.  Meanwhile core goods (commodities excluding food and energy commodities) fell 1.7% a.r. in August, and is now down 2.2% over the past 12 months.  And owner-equivalent rent, rose 2.8% a.r. for the month but is up a modest 2.2% since the summer of 2002.[1]  Overall, there isn’t much here to lose sleep over.

 

            What matters here is how the committee members are thinking about the economy.  My sense is that their logic goes something like this.  Whether inflation rises or falls in the near term depends critically on what is happening in the real economy.  While some economists may not like looking at the world through the lens of textbook macroeconomic models, many of the people inside the Federal Reserve System use complex version of these to derive their forecasts of inflation and growth. They tell that inflation goes up when output is above potential, and it goes down when output is below potential.

 

            Okay, so if inflation dynamics depends on the “output gap”, the big question is: How large is the output gap?   While many people are coming to believe that trend growth is now around 3¼%, there is disagreement over how big the gap is. If output was running above potential in the few years prior to the slowdown, then the gap could be relatively small.  But if the 1995-2000 period was one in which output was right around potential, then the gap today could be fairly big.  Evidence from the labor market provides strong support for the latter view.  Looking at things like the ratio of jobs to the total working age population, we would conclude that the economy is down something like 5 million jobs since the beginning of 2001.  Even a conservative estimate suggests that the economy won’t be back to any sort of full employment until it has recovered at least half of these, plus generated new jobs to accommodate the natural labor force growth of about 1 percent per year. This is the point at which the FOMC will start to forecast an inflation increase, and that is when interest rates are likely to start to rise again.

[1] Even this is likely to be an overstatement. While OER tends to be very stable because of the manner in which rental data is collected, there are some minor hitches arising from its treatment of energy prices. As Ben Bernanke emphasized in comments on September 4, because of the way in which the BLS treats utilities on rentals, OER inflation tends to be underestimated when energy prices are rising and overestimated when energy prices are falling.
