Krugman on Why the Stimulus is Not Enough, Part 3

Krugman has been doing some research.

So we’re something like 8 percent below where we should be. That translates into lost output at a rate of well over a trillion dollars per year (as well as mass unemployment).

Since there’s nothing in the data or anecdotal evidence suggesting any gap-closing in progress, this is a continuing tragedy.
