Did the Stimulus Work? Two Economists Say 'Yes.'

The New York Times reports on a study by Alan Blinder and Mark Zandi:

Like a mantra, officials from both the Bush and Obama administrations have trumpeted how the government’s sweeping interventions to prop up the economy since 2008 helped avert a second Depression.

Now, two leading economists wielding complex quantitative models say that assertion can be empirically proved.

In a new paper, the economists argue that without the Wall Street bailout, the bank stress tests, the emergency lending and asset purchases by the Federal Reserve, and the Obama administration’s fiscal stimulus program, the nation’s gross domestic product would be about 6.5 percent lower this year.

In addition, there would be about 8.5 million fewer jobs, on top of the more than 8 million already lost; and the economy would be experiencing deflation, instead of low inflation.

The paper, by Alan S. Blinder, a Princeton professor and former vice chairman of the Fed, and Mark Zandi, chief economist at Moody’s Analytics, represents a first stab at comprehensively estimating the effects of the economic policy responses of the last few years.

“While the effectiveness of any individual element certainly can be debated, there is little doubt that in total, the policy response was highly effective,” they write.

...

But the new analysis might not be of immediate solace to officials in the Obama administration, who have been trying to promote the “summer of recovery” at events across the nation in the face of polls indicating persistent doubts about the impact of the $787 billion stimulus program.

For one thing, Mr. Blinder and Mr. Zandi find that the financial stabilization measures — the Troubled Asset Relief Program, as the bailout is known, along with the bank stress tests and the Fed’s actions — have had a relatively greater impact than the stimulus program.

Told about the findings, another leading economist was unconvinced.

“I’m very surprised that they find these big impacts,” said John B. Taylor, a Stanford professor and a senior fellow at the Hoover Institution. “It doesn’t correspond at all to my empirical work.”

Mr. Taylor said the Fed had successfully stabilized the commercial paper and money markets, but he argued that its purchases of $1.25 trillion in mortgage-backed securities have not been effective. And he said the Obama administration’s stimulus program has had “very little impact and not much to show for it except a legacy of higher debt.”
