In the op-ed piece quoted below, Nobel-prize winner Gary Becker, along with Kevin Murphy, express reservations about the recently-passed stimulus bill, although they apparently do not go quite as far as Harvard economist Robert Barro, who believes the multiplier may be close to zero (which would imply no stimulus from the stimulus bill).
Although Becker and Murphy believe that there will be some stimulus, they emphasize that the costs will be substantial:
(p. A17) The increased federal debt caused by this stimulus package has to be paid for eventually by higher taxes on households and businesses. Higher income and business taxes generally discourage effort and investments, and result in a larger social burden than the actual level of the tax revenue needed to finance the greater debt. The burden from higher taxes down the road has to be deducted both from any short-term stimulus provided by the spending program, and from its long-run effects on the economy.
