Since the beginning of the economic crisis Paul Krugman has been the loudest advocate for a down-the-line, damn-the-torpedoes Keynesian approach. He continues to press this point in his latest op-ed column at the New York Times, which I would link except that it requires a registration.
Krugman knows his economics (and if you forget about that, his Nobel Memorial Prize will remind you). He's been writing cogently and presciently since nearly the beginning of the financial crisis (which long predates the economic one) about the clear and present danger of falling into a deflationary spiral.
Paul Krugman knows how mathematical models work as well as anyone. His problem is that he has a much more pedestrian understanding of how people work. This problem typifies the whole Obama Administration, which pays close attention to Krugman at his perch in Princeton, and professes to revere data rather than ideology.
In his latest column, Krugman cites an analysis by the Congressional Budget Office to the effect that over the next three years, the US economy will underperform its capacity by $2.9 trillion. (Of course, no color on the methodology or the approach of the study, but he's writing an op-ed piece, not an academic paper.) Let's take that large number on faith. It works out to about 7 percent of GDP.
This is the starting point from which Krugman goes on to call for government stimulus spending of about an equal size. Let's deconstruct the thinking a bit.
Something very important has been missing from the debate about fiscal stimulus. There are two really good reasons to oppose the Obama stimulus bill.
First, it's got be to just about the most hasty and poorly thought-out piece of legislation ever to come out of the US Congress. (Isn't it ironic that it also happens to be the biggest expansion of government spending ever?) This bill is so full of waste, earmarks and pork-barrel spending that Obama will have to use all his charm and deception to blow it past the American people.
Second, and this is what you hear from a lot of Congressional Republicans, the bill expands the Federal deficit tremendously.
It's being suggested by many sharp observers that global investors (like the Chinese) will be unwilling to fund this stimulus package, and will demand much higher interest rates on US debt.
Not quite. This deficit will be a lot easier to fund than many people think. It's what comes later on that we have to worry about.
Barack Obama has been very consistent about several elements of his storyline. It has three basic parts: First, the financial system just needs a little confidence. Second, the economy just needs a huge dose of spending on left-wing priorities. Third, and key to the point here, tax cuts don't work.
Obama always frames the point about taxes in a political context, something like: "the last eight years have proven that tax cuts are bad for the economy." So by taking him at his word, I'm at risk of misreading statements that may be meant only to shift blame for the difficult economy onto the Republicans. But here goes, anyway.
The great and abiding fear of Obama and his advisers, is a deflationary spiral, in which wages and prices fall, and people who owe money find it harder and harder to get by. (Debt-service generally consists of periodic payments of fixed size, so if the real value of the payments increases as overall prices fall, then debtors start defaulting more.)
And history suggests when you get a deflationary spiral, you can't get out of it, and it sticks around for years. What history? The Great Depression, and the "lost decade" in Japan. (Shockingly, Obama even mentioned the lost decade in his press conference the other night. Aren't Presidents supposed to avoid talking about worst-case scenarios?)
Unfortunately, there are several big problems with Obama's approach. First, he really doesn't know what he wants to do about the problem, other than spend nearly a trillion borrowed dollars to increase funding for a vast array of government programs, many of which are priorities of the political left wing.
Second, the President is profoundly misreading the mood of the country. The other night on national television, he repeated almost literally the conventional wisdom that the economy suffers when people save more money. (Confusingly, he also warned us that the era of debt-financed consumption and investment is over.)
I live in New York City. I talk to a lot of businesspeople, investors, and Wall Streeters. I don't talk to all that many ordinary people.
But I enjoy being interviewed on live radio in other parts of the country. And when I do that, I get the chance to hear what local callers think about the economy, and more importantly, what they want.
They want to save a lot more money. This answer comes up automatically, without qualification, and without exception when you talk to ordinary folks.
When did this desire to save materialize? It was pretty sudden. If you look at official statistics (both the Commerce Department and the St. Louis Fed publish relevant ones), the personal saving rate suddenly ticked up to between 2 and 3 percent about four months ago. Remember, it had been running nearly zero before the financial crisis started. We had one month when personal savings jumped over 5%.
Curious? Sure enough, it was May 2008. That's when the tax rebate checks went out.
I won't try to explain the sudden desire on the part of consumers to start saving, after decades of dissaving, although that's certainly an interesting question. Sometimes the pendulum just has to swing the other way. If you try to associate the shift with some contemporaneous event (like an acute financial crisis, or the gasoline-price spike), you risk mistaking cause for effect.
Up tomorrow morning is the initial reading of GDP for Q4 2008. Most of the estimates are centering around contraction at an annual rate of 5.5% or a little more.
The long-term growth trendline over the last several decades has been about 2%, with the better periods running closer to 3%. This is a little better than the demographic increase. If you still believe anything Alan Greenspan says (I do), we benefited from a multi-year period of above-trend productivity improvements in the Nineties, and from globalization in this decade.
I think it's somewhat more likely that the GDP reading (which will be revised twice over the next two months) will surprise on the upside. I think a reading of minus-3% isn't out of reach. It's less likely that we'll see a surprise on the downside.
In any case, if the reading surprises, it will almost certainly change the color of the policy debate. Devotees of Macroeconomics-101, including Nobel Laureate Paul Krugman and recent convert Christina Romer, are using negative-growth expectations to scale the amount of deficit spending they think we should enact.
To spare you a lot of arithmetic and questionable assumptions, the idea is to take the expected contraction in the economy, divide by a multiplier (typically about 1.5), deficit-spend that much on anything other than tax cuts, and subsequently expect a decline in unemployment rates predicted by Okun's Law.
Some orthodox economists are calling for fiscal-deficit package of about 8% of GDP, about twice the size that Obama has proposed.
If tomorrow's GDP reading is significantly different from minus-5.5%, look for some people to revise their numerology.
Say, has anyone noticed that the stimulus projects which are getting
the most negative attention from the press and the public, actually are
the ones that orthodox Keynesianism suggests are the best ones to do?
I
admit that striking the $600 million for condoms hurts no one but the
people in China who would have manufactured the condoms. That one is a
good strike, because it's transparently a giveaway to the pro-abortion
lobby.
But spending $21 million to re-sod the National Mall is exactly the
kind of make-work that fiscal stimulus is all about. The objective
isn't to create a capital asset that will pay off in increased
productivity later on, although that's often adduced as a bonus. The
idea, as someone like Paul Krugman will readily tell you, is simply to
reflate the economy by putting money into circulation and causing it to
have a little velocity.
If you were to state this case baldly to the people, they'd
probably laugh at you. What consumers want to do more than anything in
the world at this point in time, is to SAVE A FEW BUCKS. But orthodox
economists hate this idea because it creates no velocity, no additional
GDP, and thus (according to orthodox theory) no additional employment.
What all the smart people are missing is that you can't work your way
out of a depression led by impaired consumer demand unless you increase
consumer confidence. A major tax cut is what the people need. And it
would have to have radical features to be effective, chief among them a
sharp reduction in the payroll tax, not just the income tax as proposed
weakly by Congressional Republicans.
And even the case that fiscal stimulus generates capital investment
is suspect. You don't get much more utility out of a freshly-painted
museum that no one goes to, than you do out of re-sodding the National
Mall. (By the way, you can employ 1000 people at well over $10 an hour
for a whole year, for $20 million. This isn't about re-sodding the
Mall. It's about featherbedding.)
But we're all arguing the wrong things here. Let me tell you what
the fiscal stimulus will REALLY accomplish. Except for the tax cuts
(should significant ones actually materialize), the money will all be
disbursed to the control of state governors and possibly some big city
mayors. And what will they do with it? Yes, certainly, they'll fund
some make-work ("shovel-ready") projects like bike paths, bridges to
nowhere, new paint and air conditioners for government buildings, and
(my personal favorite) Museums of the Great Depression.
But the thing these governors need more than anything else, is to
fill in gaps in their state budgets. To a first approximation, the
fiscal stimulus will be used to pay for healthcare and teacher
salaries. The most direct effect of the stimulus will be to relieve
states and cities of the need to raise taxes.
Don't hear anyone talking about that, do you?
For the
Democrats to be willing enough to strip this stuff out under political pressure tells you that
they really don't have the courage of their convictions here. This stimulus legislation is rotten to the core.
