A CONSERVATIVE ECONOMIST SLAMS THE GOP

That's not at all the point of Allan Meltzer's op-ed in the WSJ but that's what he wrote when he attacked the tax cuts that were part of last year's stimulus bill:

One piece financed temporary tax cuts. This was a mistake, and ignores the role of expectations in the economy. Economic theory predicts that temporary tax cuts have little effect on spending. Unless tax cuts are expected to last, consumers save the proceeds and pay down debt. Experience with past temporary tax reductions, as in the Carter and first Bush presidencies, confirms this outcome.

These cuts were included to get GOP votes in the Senate.
