Fellow Shortrunners,

     

     This Wednesday, the Bureau of Labor Statistics (BLS) released the most commonly watched indicator of inflation in the United States, the Consumer Price Index, for the month of June.  As I mentioned in passing last week, the CPI is an important figure in that it directly affects the economy because it is used in the formulation of COLAs, or Cost of Living Adjustments (inflation indexation).  Not only does the CPI influence COLAs for programs like Social Security, it is also heavily influential in the financial markets, determining the yield on inflation indexed securities.

     The CPI index, however, is unique from other indexes because it is so employed.  Various agencies which produce economic statistics will update the entire series to incorporate new data, new statistical methods, or other benchmark revisions.  Because payments are indexed to the CPI, benchmark revisions (those applicable to the entire series) are not easily incorporated, as they would cause too much confusion.  Instead, data is revised during the next three months after it is released.  What is essentially a four month window is then used to make the data released as accurate as possible.  The CPI was not originally intended to be a measure of the cost of living; it was meant to be a measure of the price level.

     The index, like any other, is imperfect.  The price level is determined by looking at a fixed basket of constant quality goods (some 80,000 are looked at by BLS), and each good is weighted by  the chance that a consumer would purchase it.  This type of index is known as a Laspeyres index and has come under criticism recently because it is said to overstate inflation.  The CPI, it has been argued, overstates inflation (even if only slightly) because it can't properly take into account quality change (i.e., there is quite a bit of difference between a $1000 computer purchased in 1990 and a $1000 computer bought in 2000).  Second, changes in consumer preference and taste cannot be perfectly measured by the index.  This is because the basket (a typical set of goods) is fixed for a period of time.    

   For the great majority of its history (the CPI was officially introduced in 1978, but the US government has been collecting data on the price level since the late 1800's), the CPI has existed in this form.  In 1997, advances in data collection and larger budgets allowed statisticians to take advantage of better methods.  One such method for measuring change in an index was developed by the economist Irving Fisher in 1922.  Today, BLS has created a new CPI, released as "An Experimental CPI with Geometric Means," and this index is a chain-weighted fisher index, meaning that it incorporates changing consumption in a more accurate manner.  Simply put, the new series provides a more accurate measure of inflation.

     These statistical advances have been applied to a range of economic statistics.  However, the CPI has been unable to incorporate the change into its historical data because of its use for indexation.  As such, historical data for inflation will remain slightly overstated.  Does it make any difference?  Although its been a big issue both economically and politically, it probably does not matter.  Contemporary thought estimates that inflation has been overstated by 1/4th of 1% each year.  Economists can get revised data in a new series, so they can still employ the more accurate results.  Furthermore, those receiving benefits for social security and other COLA programs benefited from the slightly overstated changes in cost of living.

    An interesting side note is that the CPI revisions have in a way "helped" to lower the recorded levels of inflation in the United States.  Praise for our current chairman Greenspan has been largely due to his ability to fight inflation in the US.  Fortunately for him, statistical improvements have made his job all that much easier, lowering recorded levels of inflation.

      

Sincerely,
Daniel Hicks

Economic Releases


The data section provides charts and data for the most important economic indicators.

Business Inventories: 0.0%

  • Business inventories showed little signs of significant flux in May.  Behind the overall release of a 0% change was a rise in wholesale and retail inventories and a draw down in manufacturing stocks.  While business inventories were flat during May, an increase in business sales has led to a slight turnaround in the inventory/sales ratio.  The inventory to sales ratio now stands at 1.42.
Industrial Capacity: -0.7%
  • Perhaps the most pessimistic figure with respect to growth in the United States that has been available in recent months has been industrial production.  This raw measure of economic output declined a strong 0.7% last month, and has declined for the past nine months.  The slowdown in the industrial production is representative of several things.  First, it indicates that the manufacturing sector in the US is certainly in recession and contracting its output.  Second, it indicates that overall demand for raw and intermediate goods in the US is slipping.  Next, it suggests that business over-invested in capital and inventories, leading to a sharper than expected slowdown.  Capacity utilization, released alongside industrial production, fell to 77% and has been dropping like a rock.  Capacity utilization, which gives us an indication of how much of the economy's productive capability is being employed, has fallen nearly 5% from yearly highs.  This is mixed news.  If utilization rates decrease, as they have, it indicates a slowing economy.  At the same time, lower capacity utilization rates can help to prevent inflationary pressure from taking hold in the economy.
NAHB Housing Market Index: 56%
  • The National Association of Home Builders index fell two percent to 56% from 58% in July.  The index is centered around 50, with numbers above 50 indicating growth.  Although, growth decelerated, the overall housing market remains elevated and is helping to keep the economy as a whole afloat.
Consumer Price Index: 0.2% Core 0.3%
  • In June, the economy experienced a slight bump in recorded inflation.  The overall rate, employed in the production of COLA's rose 0.2%.  Core inflation, arguably just as important to economists showed an even larger rise of 0.3%.  On a year over year basis, the consumer price index has risen 2.7%.  Interestingly enough, overall price index were not strongly affected by a significant drop in energy prices.
Housing Starts: 0.3%
  • Housing starts, one of the more popular indicators of the housing market because it indicates the commencement of a process of housing construction, rose 0.3% during the month of June to 1,658,000 units.  Strength in the housing market has recently come from single family residential home building.
Jobless Claims: 414,000
  • Reigning in slightly from the week before last's phenomenally large jump in jobless claims, total claims totaled 414,000 during the week.  As it stands, the general trend in jobless claims appears to be indicating a labor market which is certainly not improving and may even be deteriorating slightly.  Rising unemployment in the US may help to ease inflationary pressure but it certainly won't help to stimulate demand.
Trade Balance: -$28.3 Billion
  • The overall trade balance for the United States improved to a deficit of $28.3 billion in May.  The contraction of the deficit was the result of both strong exports and contracting imports.  Import demand fell in every category for which it was measured as the US economy cools down and begins to demand lower amounts of foreign goods.  One factor which has recently helped to release some of the slack from the trade balance has been the decreasing petroleum prices.   
Index of Leading Indicators: 109.6
  • During June, the index of leading indicators rose slightly to 109.6.  The leading index has been increasing for the past three weeks, foretelling a slight improvement in the overall economy in the near future.  The lagging index, which gives a reading of past economic activity, continued to decline, indicating that the US economy has indeed been slipping rapidly.
ECRI Weekly Leading Index: 119.9
  • Mirroring the Index of Leading Indicators, the ECRI Weekly Leading Index rose to 119.9 last week.  The weekly leading index has been suggesting that the US economy will fall into a recession, and judging from the index's lead time, it is likely suggesting that the economy will still get worse before it gets better.
Treasury Budget: $31.9 Billion
  • The Treasury, acting as fiscal agent, recorded a surplus of $31.9 billion during June.  The cumulative surplus for Fiscal Year 2001 stands at $169 billion, slightly less than the surplus present at the same time last year (this is most likely due to changes in the receipt schedule).  Interestingly enough, corporate profits which have been key in the budget surpluses realized over the past few years saw an extremely significant drop.
