The Gaping Gap

Paul Krugman has been very vocal of the need for an aggressive fiscal stimulus plan. He acknowledges the resultant deficits are a problem, but they're a problem for down the road. For now, we need to inject enough public spending to offset the fall-off in private spending to ensure the U.S. economy doesn't suffer the same fate that Japan's did, or worse.

However, in The Obama Gap, Krugman says that the government's fiscal stimulus plans simply won't be sufficient for the task at hand.

"I don’t believe it’s too late to change course, but it will be if we don’t take dramatic action as soon as possible. If nothing is done, this recession could linger for years."

So declared President-elect Barack Obama on Thursday, explaining why the nation needs an extremely aggressive government response to the economic downturn. He’s right. This is the most dangerous economic crisis since the Great Depression, and it could all too easily turn into a prolonged slump.

But Mr. Obama’s prescription doesn’t live up to his diagnosis. The economic plan he’s offering isn’t as strong as his language about the economic threat. In fact, it falls well short of what’s needed.

Bear in mind just how big the U.S. economy is. Given sufficient demand for its output, America would produce more than $30 trillion worth of goods and services over the next two years. But with both consumer spending and business investment plunging, a huge gap is opening up between what the American economy can produce and what it’s able to sell.

And the Obama plan is nowhere near big enough to fill this "output gap."

Earlier this week, the Congressional Budget Office came out with its latest analysis of the budget and economic outlook. The budget office says that in the absence of a stimulus plan, the unemployment rate would rise above 9 percent by early 2010, and stay high for years to come.

Grim as this projection is, by the way, it’s actually optimistic compared with some independent forecasts. Mr. Obama himself has been saying that without a stimulus plan, the unemployment rate could go into double digits.

Even the C.B.O. says, however, that "economic output over the next two years will average 6.8 percent below its potential." This translates into $2.1 trillion of lost production. "Our economy could fall $1 trillion short of its full capacity," declared Mr. Obama on Thursday. Well, he was actually understating things.

To close a gap of more than $2 trillion — possibly a lot more, if the budget office projections turn out to be too optimistic — Mr. Obama offers a $775 billion plan. And that’s not enough.

Now, fiscal stimulus can sometimes have a "multiplier" effect: In addition to the direct effects of, say, investment in infrastructure on demand, there can be a further indirect effect as higher incomes lead to higher consumer spending. Standard estimates suggest that a dollar of public spending raises G.D.P. by around $1.50.

But only about 60 percent of the Obama plan consists of public spending. The rest consists of tax cuts — and many economists are skeptical about how much these tax cuts, especially the tax breaks for business, will actually do to boost spending. (A number of Senate Democrats apparently share these doubts.) Howard Gleckman of the nonpartisan Tax Policy Center summed it up in the title of a recent blog posting: "lots of buck, not much bang."

The bottom line is that the Obama plan is unlikely to close more than half of the looming output gap, and could easily end up doing less than a third of the job.

Why isn’t Mr. Obama trying to do more?

Is the plan being limited by fear of debt? There are dangers associated with large-scale government borrowing — and this week’s C.B.O. report projected a $1.2 trillion deficit for this year. But it would be even more dangerous to fall short in rescuing the economy. The president-elect spoke eloquently and accurately on Thursday about the consequences of failing to act — there’s a real risk that we’ll slide into a prolonged, Japanese-style deflationary trap — but the consequences of failing to act adequately aren’t much better.

Is the plan being limited by a lack of spending opportunities? There are only a limited number of "shovel-ready" public investment projects — that is, projects that can be started quickly enough to help the economy in the near term. But there are other forms of public spending, especially on health care, that could do good while aiding the economy in its hour of need.

Or is the plan being limited by political caution? Press reports last month indicated that Obama aides were anxious to keep the final price tag on the plan below the politically sensitive trillion-dollar mark. There also have been suggestions that the plan’s inclusion of large business tax cuts, which add to its cost but will do little for the economy, is an attempt to win Republican votes in Congress.

Whatever the explanation, the Obama plan just doesn’t look adequate to the economy’s need. To be sure, a third of a loaf is better than none. But right now we seem to be facing two major economic gaps: the gap between the economy’s potential and its likely performance, and the gap between Mr. Obama’s stern
economic rhetoric and his somewhat disappointing economic plan.
