These tax multipliers are about -1.1, whichmeans that increases in marginal tax rates that raise tax revenue by say $300billion would lower GDP by over $300 billion in the following year.

税收乘数大约是-1.1。 这意味着，边际税率增长，增加了——比如说——3，000亿美元税收，这会在之后一年降低GDP超过3，000亿美元。

The most striking claim associated with the theory - that cuts in marginal rates could generate so much extra work effort that tax revenue would rise - is unlikely to apply except in extreme cases.

该理论被抨击最多的见解是削减边缘税率可以造成许多额外的工作效果，这会导致税收增加，但除却在极端情况下之外，这种说法很难适用于一般情况。

Any realistic, practical plan to limit tax expenditure cuts to a high-income group would require a phase-in of the cuts or other accommodations, which would add to marginal tax rates, reduce the potential revenue gain, and make the resulting tax change more regressive.

Certainly, raising an equivalent amount of tax revenue through means other than increases in marginal tax rates would likely have a smaller negative incentive effect.
