Stimulus: Spending vs. Tax Multipliers

Greg Mankiw has a post today look at the real world studies of spending and tax multipliers. Keynesians might be surprised to learn that the tax multiplier appears to be much larger than the spending one. Studies put the Government spending multiplier at or around 1-1.4 while other studies have the tax cut multiplier at or around 3. This means that for ever dollar cut in taxes, we get a 3 dollar increase in GDP.
He ends with some good advise to President Elect Obama:
My advice to Team Obama: Do not be intellectually bound by the textbook Keynesian model. Be prepared to recognize that the world is vastly more complicated than the one we describe in ec 10. In particular, empirical studies that do not impose the restrictions of Keynesian theory suggest that you might get more bang for the buck with tax cuts than spending hikes.
I have a feeling we’re definitely going to see a spending increase though, so I’m not sure whether to hope for a tax cut or not.
