Great piece by Lawrence Lindsey in The Weekly Standard on the stimulus bill and the recent Blinder-Zandi analysis of it:

This is the economic equivalent of assuming there are 1,000 angels on the head of a pin, observing that we have 10 pins, and therefore calculating that we must have 10,000 angels. The math is fine. But it sheds no light on the key policy issue—were the recently passed acts of government stimulus cost effective? The degree of cost effectiveness was an assumed number, not one calculated using any version of the scientific method.

From a macroeconomic perspective, a targeted bill would have injected money directly into the cash flow of American households and small businesses where it was needed. Many of us who supported the administration’s call for a stimulus in early 2009 recommended the reduction of the payroll tax for both employers and employees, something with the same net revenue effect as what was passed. Such a payroll tax cut would have provided an incentive at the margin for continued work and employment for more than 90 percent of the labor force. The tax provision in the actual stimulus that passed did so for less than 15 percent of the labor force, and the spending provisions impacted only 2 percent of the labor force even under the administration’s assumptions. That is bad targeting.
