The myth of the multiplier: why the stimulus package hasn't reduced unemployment.

GIVE US MONEY, and we'll give you jobs. That was the promise President Barack Obama made when he asked Congress for a $789 billion stimulus bill. The cash, he said, would create millions of jobs during the next two years. Without the stimulus, the administration warned in a January report by economic advisers Christina Romer and Jared Bernstein, unemployment by the end of 2010 would reach as high as 9 percent.

Well, Obama got his money. Since then, the economy has shed more than 2 million jobs and the unemployment rate has climbed to 9.4 percent. By May 2009, the Council of Economic Advisers (CEA) had changed its message. Now the stimulus would "save or create" 3.5 million jobs by the end of 2010.

Measuring total jobs "saved" by a piece of legislation is as difficult as measuring total crimes prevented by police patrols. That's why no agency--not the Labor Department, not the Treasury, not the Bureau of Labor Statistics--actually calculates "jobs saved." As the University of Chicago economist Steven J. Davis told the Associated Press, using saved jobs as a yardstick "was a clever political gimmick to make it even harder to determine whether this policy has any effect."

A look at the CEA's job creation model undercuts its promises even more. The model's calculation of saved or created jobs is based on a macroeconomic estimate, not on actual data. According to the authors, the estimate rests on a "rough correspondence over history" that indicates a 1 percent increase in gross domestic product (GDP) represents an increase of I million jobs. They might as well have said the estimate was picked at random.

How did they come up with the 1 percent figure? Since government spending is increasing, and since such spending is a component of GDP, they assumed GDP would grow whether or not the spending produced real growth in the economy. This is akin to assuming I will have a baby in nine months whether or not I am pregnant.

The May report concedes that while the CEA will attempt to measure job creation through data collected from stimulus recipients, the results will contain errors and inconsistencies. "Because of these limitations," it warns, "the reported jobs numbers will need to [be] used with caution and as part of a more complex estimation strategy."

Since then, Romer has told CNBC she couldn't say for sure how many jobs would be created, since we can't know what would have happened without the stimulus. But didn't her report project what would...
