There is so much fog and uncertainty — much of it intentionally injected into the debate — about the different moving parts of the Stimulus Bill. But some of the broad outlines are arresting and straightforward.

We’re hearing all this talk about the staggering size of the bill. And it is a staggering amount of money. But according to Dean Baker, co-director of the Center for Economic and Policy Research, the amount of demand that the financial crisis is pulling out the economy is likely to be between $1.1 and $1.2 trillion this year (and that is not a controversial estimate). The Stimulus Bill (which, remember, is $800+ billion over two years ) would try to compensate for that drop off with about $400 billion of spending and tax cuts. How efficiently the money is spent, how quickly and so forth — all very good questions. But judged in these terms you start to see how the real question is whether any bill of that size is enough.

David Kurtz and Baker discuss the issue in today’s episode of TPMtv.
