In this morning’s Wall Street Journal, Princeton’s Alan Blinder suggests a way to increase fiscal stimulus, deliver aid to those who need it most and avoid increasing federal deficits–all at the same time. Here’s his plan, in his own words:

Let the upper-income tax cuts expire on schedule at year end. That would save the government an estimated $75 billion over the next two years. However, it would also diminish aggregate demand a bit. So, instead of using the $75 billion to reduce the deficit, spend it on unemployment benefits, food stamps and the like for two years. That would surely put more spending into the economy than the tax hike takes out, thus creating jobs.

How much more? Getting a numerical estimate requires the use of a quantitative model of the U.S. economy. In recent testimony before the House Budget Committee, Mark Zandi of Moody’s Analytics used his model to estimate that extending unemployment insurance benefits has almost five times as much “bang for the buck” as making the Bush tax cuts permanent.

Based on his estimates, the budgetary trade I just recommended would add almost $100 billion to aggregate demand over the next two years—without adding a dime to the deficit.
