How much fraud is there?

We have an estimate!

Fraud typically gobbles up around 7% of all big contracts.

This is from Watchdog Over Stimulus Spending Toes a Delicate Line, by Neil King, Jr., WSJ 3/9/09. Altho no source is cited, the implication is that this came from Earl Devaney, who according to the article heads the federal Recovery Act Accountability and Transparency Board.

I guess that’s just fraud.  Waste and inefficiency are things entirely different.
