There are two measures of income: the spending side (Gross Domestic Product, or GDP) and the income side (Gross Domestic Income, GDI). I’d like to see what GDI is telling us about the Y/Y recovery, since it’s a better predictor of turning points, according to FRB economist Jeremy J. Nalewaik.
The chart illustrates the contribution to Y/Y GDI growth coming from each of the main income components. (Click to enlarge.)The series is deflated using the GDP deflator, since the BEA only releases the nominal numbers. All references to GDP and GDI below refer to the real series.
Observations I note:
1. The Y/Y growth rate of GDI surpassed that of GDP in Q2 2010, continuing into Q3 2010. In Q3 2010, GDI grew at a 3.6% annual clip, while GDP marked a lesser 3.2% rate. Don’t know what this means, exactly; but it could imply that the economy is expanding more rapidly than the GDP measure would suggest.
2. The Q3 2010 corporate profit contribution to annual income growth, 2.2%, is overwhelming that from wages and salary accruals (labor income), 0.73%. This oversized contribution is rather remarkable, given that domestic corporate profits are just 8% of GDI, while that of wages and salaries is 55%. This will probably even out, though, as history shows a more balanced contribution between profits and wages.
3. The chart illustrates the ‘stickiness’ of labor income. The corporate profit contribution turned negative in Q4 2006, while that of wages and accruals turned negative in Q3 2008. That’s a near 2-yr lag from profits to wages. Wages are recovering now; but there will be further quarters of weak wage growth relative to profits, as claims remain elevated above the 350k mark.
4. The contribution to GDI growth from net interest payments is in negative territory. Low rates are dragging this component.
5. Supplements to wages and salaries – government transfer payments like unemployment insurance, for example – contributed 0.3% to annual GDI growth in Q3 2010. Interesting thing about this, is that the average contribution spanning the 2000-2004 period, 0.5%, outweighs that during the 2005-2010 period, 0.14%. I say interesting because the labor decline was far deeper in this cycle compared to the previous cycle. (See Calculated Risk chart from 12.3.2010)
Overall, the GDI report implies that the economy may be improving more quickly than the GDP report suggests. There’s plenty of room for improvement in this picture, however, as the labor wages remain stuck in the mud with corporate profits strong.
Tomorrow we’ll see the Q4 2010 GDP report – consensus forecast is for 3.5% Q/Q SAAR.
