EK: You think the danger posed by the long-term deficit is overstated by most economists and economic commentators.
JG: No, I think the danger is zero. It’s not overstated. It’s completely misstated.
JG: What is the nature of the danger? The only possible answer is that this larger deficit would cause a rise in the interest rate. Well, if the markets thought that was a serious risk, the rate on 20-year treasury bonds wouldn’t be 4 percent and change now. If the markets thought that the interest rate would be forced up by funding difficulties 10 year from now, it would show up in the 20-year rate. That rate has actually been coming down in the wake of the European crisis.
So there are two possibilities here. One is the theory is wrong. The other is that the market isn’t rational. And if the market isn’t rational, there’s no point in designing policy to accommodate the markets because you can’t accommodate an irrational entity.
EK: Then why are the bulk of your colleagues so worried about this?
JG: Let’s push a bit deeper on the CBO forecasts. They publish a baseline set of projections. One of those projections holds the economy will return to a normal high-employment level with low inflation over the next 10 years. If true, that would be wonderful news. Go down a few lines and they also have the short-term interest rate going up to 5 percent. It’s that short-term interest rate combined with that low inflation rate that allows them to generate, quite mechanically, these enormous future deficit forecasts. And those forecasts are driven partially by the assumption that health-care costs will rise forever at a faster rate than everything else and by interest payments on the debt will hit 20 or 25 percent of GDP.
At this point, the whole thing is completely incoherent. You cannot write checks to 20 percent to anybody without that money entering the economy and increasing employment and inflation. And if it does that, then debt-to-GDP has to be lower, because inflation figures into how much debt we have. These numbers need to come together in a coherent story, and the CBO’s forecast does not give us a coherent story. So everything that is said that is based on the CBO’s baseline is, strictly speaking, nonsense.
EK: But couldn’t there be a space between the CBO being totally correct and the debt not being a problem? It seems certain, for instance, that health-care costs will continue to rise faster than other sectors of the economy.
JG: No, it’s not reasonable. Share of health-care cost would rise as part of total GDP and the inflation would rise to be nearer to what the rate of health-care inflation is. And if health care does get that expensive, and we’re paying 30 percent of GDP while everyone else is paying 12 percent, we could buy Paris and all the doctors and just move our elderly there.
EK: But putting inflation aside, the gap between spending and revenues won’t have other ill effects?
JG: Is there any terrible consequence because we haven’t prefunded the defense budget? No. There’s only one budget and one borrowing authority and all that matters is what that authority pays. Say I’m the federal government and I wish to pay you, Ezra Klein, a billion dollars to build an aircraft carrier. I put money in your bank account for that. Did the Federal Reserve look into that? Did the IRS sign off on it? Government does not need money to spend just as a bowling alley does not run out of points.
What people worry about is that the federal government won’t be able to buy bonds. But there can never be a problem for the federal government selling bonds. It goes the other way. The government’s spending creates the bank’s demand for bonds, because they want a higher return on the money that the government is putting into the economy. My father said this process is so simple that the mind recoils from it.
EK: What are the policy implications of this view?
JG: It says that we should be focusing on real problems and not fake ones. We have serious problems. Unemployment is at 10 percent. if we got busy and worked out things for the unemployed to do, we’d be much better off. And we can certainly afford it. We have an impending energy crisis and a climate crisis. We could spend a generation fixing those problems in a way that would rebuild our country, too. On the tax side, what you want to do is reverse the burden on working people. Since the beginning of the crisis, I’ve supported a payroll tax holiday so everyone gets an increase in their after-tax earnings so they can pay down their mortgages, which would be a good thing. You also want to encourage rich people to recycle their money, which is why I support the estate tax, which has accounted for an enormous number of our great universities and nonprofits and philanthropic organizations. That’s one difference between us and Europe.
