Real Personal Income and GDP

real personal income less transfer payments is still 3.4% below the previous peak.

It appears that GDP bottomed in Q2 2009 and GDI in Q3 2009. Real GDP finally reached the pre-recession peak in Q4 2010, but real GDI is still slightly below the previous peak.

Using GDI, the economy will be back to the pre-recession peak in Q2 2011.

1st Quarter 2010 GDP revised down to 3.0%

There are really two measures of GDP: 1) real GDP, and 2) real Gross Domestic Income (GDI). The BEA also released GDI today. Recent research suggests that GDI is often more accurate than GDP...

The following graph is constructed as a percent of the previous peak in both GDP and GDI. This shows when the indicator has bottomed - and when the indicator has returned to the level of the previous peak. If the indicator is at a new peak, the value is 100%. The recent recession is marked as ending in Q3 2009 - this is preliminary and NOT an NBER determination...

It appears that GDP bottomed in Q2 2009 and GDI in Q3 2009. Real GDP is only 1.2% below the pre-recession peak - but real GDI is still 2.3% below the previous peak.

GDI suggests the recovery has been more sluggish than the headline GDP report and better explains the weakness in the labor market.

GDP v GDI

Fed economist Jeremy Nalewaik examined the differences in GDP and a closely-related measure, gross domestic income. GDP measures the output of the economy as the sum of expenditures — consumption, plus investment plus government spending plus net exports. GDI measures total income in the economy.

In theory, the two measures should equal one another, in practice they don’t quite, and Mr. Nalewaik argues that GDI is the better of the two.

He finds that when the Commerce Department’s Bureau of Economic Analysis revises its national income and product accounts, GDP figures move more closely inline with GDI. GDI also appears to have a stronger correlation with other economic indicators, and its recent movement around turning points suggests it more closely tracks the economy.

He notes that GDI fell far more sharply in the teeth of the recession, dropping at a 7.3% annual rate in the fourth quarter of 2008, and 7.7% in the first quarter of 2009. GDP, in comparison, fell by 5.4% and 6.4%. Moreover, while GDP showed the economy began to grow in last year’s third quarter, GDI showed it continued to contract. (Fourth-quarter GDI figures aren’t yet available.)
