Where's the Investment?

Calculated Risk posted some great recession measure "drawdown" charts:

• Real GDP / GDI
• Real income less transfer payments
• Industrial Production
• Employment

One additional area not outlined in the post was investment, which is the only component of GDP (of the C + I + G + NX) to still be in negative territory relative to pre-crisis levels.

The bulk of the decline is concentrated in residential investment, but non-residential investment has declined over that time as well.
