Jamie Galbraith’s Letter to Former CEA Chairs

Jamie Galbraith has written an excellent letter to the four former Chairs of the Council of Economic Advisers under Clinton and Obama regarding their letter to Professor Gerald Friedman and Senator Bernie Sanders. The full text is below.


February 18, 2016

I was highly interested to see your letter of yesterday’s date to Senator Sanders and Professor Gerald Friedman. I respond here as a former Executive Director of the Joint Economic Committee – the congressional counterpart to the CEA.

You write that you have applied rigor to your analyses of economic proposals by Democrats and Republicans. On reading this sentence I looked to the bottom of the page, to find a reference or link to your rigorous review of Professor Friedman’s study. I found nothing there.

You go on to state that Professor Friedman makes “extreme claims” that “cannot be supported by the economic evidence.” You object to the projection of “huge beneficial impacts on growth rates, income and employment that exceed even the most grandiose predictions by Republicans about the impact of their tax cut proposals.”

Matthew Yglesias makes an important point about your letter:

“It’s noteworthy that the former CEA chairs criticizing Friedman didn’t bother to run through a detailed explanation of their problems with the paper. To them, the 5.3 percent figure was simply absurd on its face, and it was good enough for them to say so, relying on their authority to generate media coverage.”

So, let’s first ask whether an economic growth rate, as projected, of 5.3 percent per year is, as you claim, “grandiose.” There are not many ambitious experiments in economic policy with which to compare it, so let’s go back to the Reagan years. What was the actual average real growth rate in 1983, 1984, and 1985, following the enactment of the Reagan tax cuts in 1981? Just under 5.4 percent. That’s a point of history, like it or not.

You write that “no credible economic research supports economic impacts of these magnitudes.” But how did Professor Friedman make his estimates? The answer is in his paper. What Professor Friedman did, was to use the standard impact assumptions and forecasting methods of the mainstream economists and institutions. For example, Professor Friedman starts with a fiscal multiplier of 1.25, and shades it down to the range of 0.8 by the mid 2020s. Is this “not credible”? If that’s your claim, it’s an indictment of the methods of (for instance) the CBO, the OMB, and the CEA.

To be sure, skepticism about standard forecasting methods is perfectly reasonable. I’m a skeptic myself. My 2014 book The End of Normal is all about problems with mainstream forecasting.

In the specific case of this paper, one can quibble with the out-year multipliers, or with the productivity assumptions, or with the presumed impact of a higher minimum wage. One can invoke the trade deficit or the exchange rate. Professor Friedman makes all of these points himself. But those issues are well within mainstream norms.

There is no “magic asterisk,” no strange theory involved here. And the main effect of adjusting the assumptions, which would a perfectly reasonable thing to do, would be to curtail the growth rate after a few years – not at the beginning, when it would matter most.

It is not fair or honest to claim that Professor Friedman’s methods are extreme. On the contrary, with respect to forecasting method, they are largely mainstream. Nor is it fair or honest to imply that you have given Professor Friedman’s paper a rigorous review. You have not.

What you have done, is to light a fire under Paul Krugman, who is now using his high perch to airily dismiss the Friedman paper as “nonsense.” Paul is an immensely powerful figure, and many people rely on him for careful assessments. It seems clear that he has made no such assessment in this case.

Instead, Paul relies on you to impugn an economist with far less reach, whose work is far more careful, in point of fact, than your casual dismissal of it. He and you also imply that Professor Friedman did his work for an unprofessional motive. But let me point out, in case you missed it, that Professor Friedman is a political supporter of Secretary Clinton. His motives are, on the face of it, not political.

For the record, in case you’re curious, I’m not tied to Professor Friedman in any way. But the powerful – such as Paul and yourselves – should be careful where you step.

Let’s turn, finally, to the serious question. What does the Friedman paper really show? The answer is quite simple, and the exercise is – while not perfect – almost entirely ordinary.

What the Friedman paper shows, is that under conventional assumptions, the projected impact of Senator Sanders’ proposals stems from their scale and ambition. When you dare to do big things, big results should be expected. The Sanders program is big, and when you run it through a standard model, you get a big result.

That, by the way, is the lesson of the Reagan era – like it or not. It is a lesson that, among today’s political leaders, only Senator Sanders has learned.

Yours,

(Jamie)

Executive Director, Joint Economic Committee, 1981-2

5 Responses to Jamie Galbraith’s Letter to Former CEA Chairs

  1. I suggest that while Prof. Galbraith’s conclusion is spot on, one of his historical references is superficial and misused. That is the growth rate from 1983 – 1985. Yes, that was the growth rate. But it was not entirely or even mostly due to the tax cuts from 1981. That growth rate was due to the depth of the recession that began in 1980 and lasted until mid 1982. That growth rate was largely due to the domestic stimulus measures enacted, not the income tax screw up. It came from the huge increase in military procurement spending. It came from the rebound. We have not had a normal rebound from the 2007-2009 Great Recession because Pres. Obama’s team was so timid in their stimulus proposal which was watered down in Congress. We have not had a normal rebound this time because neither the president nor Congress did anything after 2011 to respond to the Great Recession with additional and appropriate stimulus measures.

    Belated but appropriate stimulus measures as Sen. Sanders is proposing is entirely likely to finally bring on the kinds of growth rates that the US economy realizes when recovering from a significant recession.

  2. I take issue with your conclusion that Sanders is the only political leader who dares to think big. I believe Greens think big and have since our founding 30 years ago. In fact, the biggest complaint within the Green Party about Senator Sanders is that he doesn’t go far enough and doesn’t connect all the dots, that are necessary for BIG change.

    For example, we cannot remain an empire with all the military spending that requires AND, build a prosperous country for all citizens. To date, Sanders has been unwilling to say anything deep and meaningful about the military industrial complex and it’s relationship to every single problem we face.

  3. Quite frankly it makes one wonder if Mr. krugman thinks he has found a back door through which he could launch another attack on MMT. The Kelton/Sanders connection.
    Professional politics or economic validity. Who thinks the former?

  4. I am a huge supporter of Sanders, and while I agree with the general thrust and results of Friedman’s analysis, even I was a bit skeptical. 5.3% growth, $82k a year average income, massive surpluses. I am not an economist, and am not quite of the techniques and models used etc etc but I have to think Friedman was a little liberal with it, and maybe should’ve toned it down….I fear some will be turned off now, given the weight of the 5 people who have slammed the plan now, and this is bad for Bernie.

    That said, I do believe in general, he is right. As long discussed here, a large scale, long term jobs program at $15/hr eventually, plus the boost to many millions that wage would give, infrastructure investment paying off, more tax revenue less welfare spending, healthcare savings etc
    In fact….is it possible for you guys at UMKC to do a forecast of Bernie Sanders entire plan?

  5. Go James.
