Cato has just published a full-page ad in the New York Times with the names of some 200 economists, including some Nobel laureates and other highly respected scholars, who “do not believe that more government spending is a way to improve economic performance” – contrary to widespread claims that “Economists from across the political spectrum agree” on a massive fiscal stimulus package. Of course, many economists don’t like to sign joint statements, so this is only a fraction of stimulus opponents in the profession. Greg Mankiw pointed to a few noted skeptics last week:

In a TV interview last month, Vice President Joe Biden said the following:

Every economist, as I’ve said, from conservative to liberal, acknowledges that direct government spending on a direct program now is the best way to infuse economic growth and create jobs.

That statement is clearly false. As I have documented on this blog in recent weeks, skeptics about a spending stimulus include quite a few well-known economists, such as (in alphabetical order) Alberto Alesina, Robert Barro, Gary Becker, John Cochrane, Eugene Fama, Robert Lucas, Greg Mankiw, Kevin Murphy, Thomas Sargent, Harald Uhlig, and Luigi Zingales–and I am sure there many others as well. Regardless of whether one agrees with them on the merits of the case, it is hard to dispute that this list is pretty impressive, as judged by the standard objective criteria by which economists evaluate one another. If any university managed to hire all of them, it would immediately have a top ranked economics department.

And of course Mankiw’s list isn’t comprehensive. There’s also former Treasury economist Bruce Bartlett, former Yale professor Philip Levy, former Ohio State and Federal Reserve economist Alan Viard, Russell Roberts of George Mason, and many more. Under the current circumstances, plenty of economists are endorsing large fiscal stimulus programs. But it’s just not correct to claim that there’s any consensus or that “every economist … from conservative to liberal” supports the kind of massive spending program that the Obama-Biden administration has proposed.

UPDATE: Martin Feldstein, whose support last October for a fiscal stimulus is the reed upon which journalists justify their claims about “economists across the political spectrum,” now calls this stimulus bill “an $800 billion mistake.”
