Second Estimate 3Q2016 GDP Revised Upward to 3.2%

Written by Doug Short and Steven Hansen

The second estimate of third quarter 2016 Real Gross Domestic Product (GDP) is a positive 3.2 %. This is an increase from the advance estimate’s +2.9 % if one looks at quarter-over-quarter headline growth. Year-over-year growth also improved from the advance estimate. The major reason for the increase was improvement in consumer spending.

The market expected:

• Headline GDP is calculated by annualizing one quarter’s data against the previous quarters data (and the previous quarter was relatively strong in this instance). A better method would be to look at growth compared to the same quarter one year ago. For 3Q2016, the year-over-year growth is 1.6 % – moderately up from 2Q2016’s 1.3 % year-over-year growth. So one might say that the rate of GDP growth accelerated 0.3 % from the previous quarter.

Real GDP Expressed As Year-over-Year Change

The same report also provides Gross Domestic Income which in theory should equal Gross Domestic Product. Some have argued the discrepancy is due to misclassification of capital gains as ordinary income – but whatever the reason, there are differences.

Real GDP (blue line) Vs. Real GDI (red line) Expressed As Year-over-Year Change

This second estimate released today is based on more complete source data than were available for the “advance” estimate issued last month. (See caveats below.)

Real GDP per Capita

The table below compares the previous quarter estimate of GDP (Table 1.1.2) with the current estimate this quarter which shows:

• consumption for goods and services significantly decelerated..
• trade balance improved and added 0.87 % to GDP
• there was significant inventory change adding 0.49 % to GDP
• except for inventory growth,there was little change in fixed investment growth
• there was more government spending

What the BEA says about the second estimate of GDP:

Real gross domestic product increased at an annual rate of 3.2 percent in the third quarter of 2016, according to the “second” estimate released by the Bureau of Economic Analysis. In the second quarter, real GDP increased 1.4 percent.

The GDP estimate released today is based on more complete source data than were available for the “advance” estimate issued last month. In the advance estimate, the increase in real GDP was 2.9 percent. With the second estimate for the third quarter, the general picture of economic growth remains the same; the increase in personal consumption expenditures was larger than previously estimated.

Real gross domestic income (GDI) increased 5.2 percent in the third quarter, compared with an increase of 0.7 percent in the second (revised). The average of real GDP and real GDI, a supplemental measure of U.S. economic activity that equally weights GDP and GDI, increased 4.2 percent in the third quarter, compared with an increase of 1.1 percent in the second.

The increase in real GDP in the third quarter primarily reflected positive contributions from personal consumption expenditures (PCE), exports, private inventory investment, and federal government spending, that were partly offset by negative contributions from residential fixed investment and state and local government spending. Imports, which are a subtraction in the calculation of GDP, increased.

The acceleration in real GDP in the third quarter primarily reflected an upturn in private inventory investment, an acceleration in exports, an upturn in federal government spending, and smaller decreases in state and local government spending and residential fixed investment, that were partly offset by a deceleration in PCE, an acceleration in imports, and a deceleration in nonresidential fixed investment.

Inflation continues to moderate as the “deflator” which adjusts the current value GDP to a “real” comparable value continues to moderate. The following compares the GDP deflator to the Consumer Price Index:

BLS explaination of the changes to 3Q2016 GDP:

The upward revision to the percent change in real GDP primarily reflected an upward revision to PCE that was partly offset by downward revisions to nonresidential fixed investment and private inventory investment.

Overview Analysis:

Here is a look at Quarterly GDP since Q2 1947. Prior to 1947, GDP was calculated annually. To be more precise, the chart shows is the annualized% change from the preceding quarter in Real (inflation-adjusted) Gross Domestic Product. We’ve also included recessions, which are determined by the National Bureau of Economic Research (NBER). Also illustrated are the 3.23% average (arithmetic mean) and the 10-year moving average, currently at 1.39%.

Here is a log-scale chart of real GDP with an exponential regression, which helps us understand growth cycles since the 1947 inception of quarterly GDP. The latest number puts us 14.9% below trend, the largest negative spread in the history of this series.

A particularly telling representation of slowing growth in the US economy is the year-over-year rate of change. The average rate at the start of recessions is 3.35%. Ten of the eleven recessions over this timeframe have begun at a higher level of real YoY GDP.

In summary, the Q3 GDP Second Estimate of 1.1 percent was the generally expected small downward revision to the Advance Estimate of 1.2 percent.

The chart below is a way to visualize real GDP change since 2007. The chart uses a stacked column chart to segment the four major components of GDP with a dashed line overlay to show the sum of the four, which is real GDP itself. As the analysis clear shows, personal consumption is key factor in GDP mathematics.

Caveats on the Use of Gross Domestic Product (GDP)

GDP is market value of all final goods and services produced within the USA where money is used in the transaction – and it is expressed as an annualized number. GDP = private consumption + gross investment + government spending + (exports − imports), or GDP = C + I + G + (X – M). GDP counts monetary expenditures. It is designed to count value added so that goods are not counted over and over as they move through the manufacture – wholesale – retail chain.

The vernacular relating to the different GDP releases:

“Advance” estimates, based on source data that are incomplete or subject to further revision by the source agency, are released near the end of the first month after the end of the quarter; as more detailed and more comprehensive data become available, “second” and “third” estimates are released near the end of the second and third months, respectively. The “latest” estimates reflect the results of both annual and comprehensive revisions.

Consider that GDP includes the costs of suing your neighbor or McDonald’s for hot coffee spilled in your crotch, plastic surgery or cancer treatment, buying a new aircraft carrier for the military, or even the replacement of your house if it burns down – yet little of these activities is real economic growth.

GDP does not include include home costs (other than the new home purchase price even though mortgaged up the kazoo), interest rates, bank charges, or the money spent buying anything used.

It does not measure wealth, disposable income, or employment.

In short, GDP does not measure the change of the economic environment for Joe Sixpack in 1970, and Joe Sixpack’s kid, yet pundits continuously compare GDP across time periods.

Although there always will be some correlation between all economic pulse points, GDP does not measure the economic elements that directly impact the quality of life of its citizens.
