| August 27, 2015 - BEA Revises 2nd Quarter 2015 GDP Growth Upward to 3.70%: |
In their second estimate of the US GDP for the second quarter of 2015, the Bureau of Economic Analysis (BEA) reported that the economy was growing at a 3.70% annualized rate, up +1.38% from their previous estimate and up +3.06% from the first quarter.
This report included significant upward revisions to the growth rate contributions from commercial fixed investment (revised upward +0.52%), inventories (up +0.30%) and government spending (up +0.33%). Consumer spending was revised upward a more modest +0.13%, and the net impact of exports and imports was also revised upward +0.10%.
Real annualized per capita disposable income was reported to be $37,843 per annum, down $3 per year from the last estimate. The household savings rate was unchanged at 4.8% -- still down -0.4% from the prior quarter's 5.2% rate.
For this revision the BEA assumed an annualized deflator of 2.07%. During the same quarter (April 2015 through June 2015) the inflation recorded by the Bureau of Labor Statistics (BLS) in their CPI-U index was 3.52%. Under estimating inflation results in optimistic growth rates, and if the BEA's "nominal" data was deflated using CPI-U inflation information the headline number would show a more modest +2.33% growth rate.
Among the notable items in the report :
-- The headline contribution from consumer expenditures for goods was +1.19% (up +0.15% from the previous estimate).
-- The contribution to the headline from consumer services decreased slightly to +0.93% (down -0.02% from the previous report). The combined consumer contribution to the headline number was 2.12%, up +0.13% from the first estimate.
-- The headline contribution from commercial private fixed investments was revised upward to +0.66% -- up an impressive +0.52% from earlier report.
-- Inventories changed from a mild contraction to a modest growth, providing +0.22% of the headline number (up +0.30% from the previous estimate).
-- Governmental spending added +0.47% to the headline (up +0.33% from the earlier report). The revised growth was almost entirely in state and local infrastructure investment.
-- Exports were slightly down from the last estimate, but still added +0.65% to the headline number (down -0.02% from the first estimate).
-- Imports subtracted less from the headline number (-0.42%) than previously reported (an improvement of +0.12%).
-- The "real final sales of domestic product" is now reported to be growing at a +3.48% annualized rate. This is the BEA's "bottom line" measurement of the economy and it excludes the reported inventory growth.
-- And as mentioned above, real per-capita annual disposable income was revised slightly downward and the household savings rate was unchanged. The real per-capita annual disposable income is up only +3.18% in aggregate since the second quarter of 2008 -- an annualized +0.45% growth over the past 28 quarters.
The Numbers, As Revised
As a quick reminder, the classic definition of the GDP can be summarized with the following equation :
or, as it is commonly expressed in algebraic shorthand :
In the new report the values for that equation (total dollars, percentage of the total GDP, and contribution to the final percentage growth number) are as follows :

Summary and Commentary
On the surface this report shows solid economic growth for the US economy during the second quarter of 2015. Unfortunately, all of the usual caveats merit restatement:
-- A significant portion of the "solid growth" in this headline number could be the result of understated BEA inflation data. Using deflators from the BLS results in a more modest 2.33% growth rate. And using deflators from the Billion Prices Project puts the growth rate even lower, at 1.28%.
-- Per capita real GDP (the number we generally use to evaluate other economies) comes in at about 1.6% using BLS deflators and about 0.6% using the BPP deflators. Keep in mind that population growth alone (not brilliant central bank maneuvers) contributes a 0.72% positive bias to the headline number.
-- Once again we wonder how much we should trust numbers that bounce all over the place from revision to revision. One might expect better from a huge (and expensive) bureaucracy operating in the 21st century. Among major economies, only the Chinese numbers are more suspect.
All that said, we have -- on the official record -- solid economic growth and 5.3% unemployment. What more could Ms. Yellen want?
