STIMULUS MATH….Goldman Sachs says we’re about to suffer the deepest recession since World War II, with unemployment expected to top 8.5% next year and maybe inching a little higher in 2010. So how big should a stimulus package be given the size of the economic tsunami we’re headed into? Paul Krugman tells us today that since Okun’s Law suggests that every point of unemployment above 5% represents a 2% output gap, an 8.5% unemployment rate means that the economy is performing 7% under its potential:

So we need a fiscal stimulus big enough to close a 7% output gap. Remember, if the stimulus is too big, it does much less harm than if it’s too small. What’s the multiplier? Better, we hope, than on the early-2008 package. But you’d be hard pressed to argue for an overall multiplier as high as 2.

When I put all this together, I conclude that the stimulus package should be at least 4% of GDP, or $600 billion.

Given the likely length of this recession, we’ll probably need nearly this much again in 2010. Call it an even trillion bucks when it’s all said and done.

As recently as a few months ago that would have seemed unimaginably large to me. Today, not so much. Stimulate away, President Obama.

DEMOCRACY DOES NOT EXIST...

without free and fair elections, a vigorous free press, and engaged citizens to reclaim power from those who abuse it.

In this election year unlike any other—against a backdrop of a pandemic, an economic crisis, racial reckoning, and so much daily crazy—Mother Jones' journalism is driven by one simple question: Will America will move closer to, or further from, justice and equity in the years to come?
