The good news is that the American Recovery and Reinvestment Act, a k a the Obama stimulus plan, is working just about the way textbook macroeconomics said it would. But that’s also the bad news  because the same textbook analysis says that the stimulus was far too small given the scale of our economic problems. Unless something changes drastically, we’re looking at many years of high unemployment.

And the really bad news is that “centrists” in Congress aren’t able or willing to draw the obvious conclusion, which is that we need a lot more federal spending on job creation.

About that good news: not that long ago the U.S. economy was in free fall. Without the recovery act, the free fall would probably have continued, as unemployed workers slashed their spending, cash-strapped state and local governments engaged in mass layoffs, and more.

The stimulus didn’t completely eliminate these effects, but it was enough to break the vicious circle of economic decline. Aid to the unemployed and help for state and local governments were probably the most important factors. If you want to see the recovery act in action, visit a classroom: your local school probably would have had to fire a lot of teachers if the stimulus hadn’t been enacted.
