December 2012 Real Personal Consumption Expenditure (PCE) – rose marginally after last months strong gain. Real Disposable Personal Income (DPI) rose strongly for the second month in a row.
- The market looks at current values (not real) and was expecting a PCE (expenditures) rise of 0.1% to 0.3% (versus 0.2% actual), and a rise in DPI (income) of 0.7% to 3.4% (versus 2.7% actual).
- this data is very noisy and as usual includes backward revision (detailed below) making real time analysis problematic – and the backward revisions this month were downward.
- Although yesterday’s advance estimate of 4Q2013 GDP release included a surprise contraction of the economy, there is no indication in this consumption data of economic softness.
The inflation adjusted numbers are chained.
Econintersect believes year-over-year trends are very revealing in understanding economic dynamics. Again, there was a broad revision this month in the data for the last six months, which is explained below (see caveats below).
Per capita inflation adjusted expenditure has exceeded this month the pre-recession peak.
Seasonally and Inflation Adjusted Expenditure Per Capita
Per capita inflation adjusted income has exceeded the pre-recession levels this month.

The graph below illustrates the relationship between income (DPI) and expenditures (PCE) – showing clearly income and expenditures grow at nearly the same rate.

The consumer was since mid 2010 was continuing to spend more of his income (and therefore saving less) – but in 2012 this trend reversed. In the last three months, however, this trend appears to be again changing again to the consumer spending more of its income. It remains in a range seen prior to the Great Recession.
Seasonally Adjusted Spending’s Ratio to Income (a declining ratio means consumer is spending less of its Income)
PCE is the spending of consumers. In the USA, the consumer is the economy. Likewise, personal income is the money consumers earn to spend. Even though most analysts concentrate on personal expenditures because GDP is based on spending, increases in personal income allow consumers the option to spend more.
There is a general correlation of PCE to GDP (PCE is a component of GDP). This index has shown negative growth several times since the end of the 2007-09 recession. PCE is a fairly noisy index and subject at times to significant backward revision (see caveats below).
Seasonally and Inflation Adjusted Year-over-Year Change of Personal Consumption Expenditures (blue line) to GDP (red line)
Econintersect uses the inflation adjusted (chained) numbers. Disposable Personal Income (DPI) is the income after the taxes.
Seasonally & Inflation Adjusted Percent Change From the Previous Month – Personal Disposable Income (red line) and Personal Disposable Expenditures (blue line)
And please note that Econintersect’s previous analysis of PCE and DPI has been somewhat changed by backward revision:
Estimates have been revised for October and November. Changes in personal income, current-dollar and chained (2005) dollar DPI, and current-dollar and chained (2005) dollar PCE for October and November — revised and as published in last month’s release — are shown below.
The savings rate has been bouncing around in 2012 – and the trend now seems to be flat (no change in the rate of growth). In an economy driven by consumers, a higher savings rate does not bode well for increased GDP. This is one reason GDP may not be a good single metric of economic activity. The question remains what is the optimal savings rate for the current demographics. It might be expected that as people near retirement, the savings rate rises and after people retire, savings rate falls. Econintersect is not aware of any study which documents this effect. The graph below is from BEA table 2.6. – and shows a significant jump in savings rate for December.
Personal Savings as a Percentage of Disposable Personal Income
And one look at the different price changes seen by the BEA in this PCE release versus the BEA’s GDP and BLS’s Consumer Price Index (CPI).

Finally for recession watchers, here is the graph below, here are the elements used to mark a recession. (1) personal income less transfer payments, in real terms and (2) employment. In addition, we refer to two indicators with coverage primarily of manufacturing and goods: (3) industrial production and (4) the volume of sales of the manufacturing and wholesale-retail sectors adjusted for price changes.
If a line falls below the 0 (black line) – that sector is contracting from the previous month. Personal income is the blue line. Note – the below graph uses multipliers to make movements more obvious (ignore the value of the scale, only consider whether the graph is above [good] or below [bad] the zero line).

Caveats on the Use of Personal Income and Consumption Expenditure Data
PCE is a fairly noisy index and subject at times to significant backward revision. This index cannot be relied upon in real time.
This personal income and personal consumption expenditure data by itself is not a good tool to warn of an upcoming recession. Econintersect has shown that PCE is a distraction for recession watchers, with moves over a few months having a 30% accuracy of indicating a recession start, and a 70% incidence of indicating a non-recessionary event. The graph below shows the lack of correlation. Note, however, that PCE does have prolonged declines over many months associated with recessions but these long declines are not very good in “predicting” a recession until it is already underway.
Readers are warned that this article is based on seasonally adjusted data. Monthly non-adjusted data is available with a delay of several months.
