Bang for the buck

Stiglitz no FT de hoje:

"But household tax cuts, except for possibly the poorest, should have no place in the stimulus. Nor should business tax breaks, except when closely linked with additional investment. The one tax cut that should be included is a temporary incremental investment tax credit; it provides a big bang for the buck, encouraging companies to invest now when the economy needs the spending. Increased investments in infrastructure, education and technology, relief to states, and help to the unemployed need pride of place."
