参议院少数党领袖米奇·麦康奈尔（Mitch McConnell）昨天 重复 the all-too-common claim that tax 切s increase government revenue:
That's been the majority Republican view for some time... [t]hat there's no evidence whatsoever that the 衬套 tax 切s actually diminished revenue. They increased revenue, because of the vibrancy of these tax 切s 在里面 经济. So I think what Senator Kyl was expressing was the view of virtually every Republican on that subject.
However, as I've 重复ly pointed out, virtually every credible economist disagrees. Even 衬套 administration economists 重复ly found the courage to disavow the claims of their political superiors -- here's 回顾:
-在CEA主席的2003年经济报告中 写 that "[a]lthough the 经济 grows in response to tax reductions... it is unlikely to grow so much that lost tax revenue is completely recovered by the higher level of economic activity."
在2003年的参议院确认听证会上，格雷格·曼基夫（Greg Mankiw） 问 关于成长俱乐部主席斯蒂芬·摩尔反对他的提名。曼奇夫回应说，摩尔在批评“ [曼奇夫的著作]中的一段话，我对皇冠手机app下载网址会带来如此多的就业增长以至完全依靠自筹资金的说法表示怀疑。对此我仍然持怀疑态度。”
-管理和预算办公室《 2006年中期评估》中包含的财政部分析 总结 that the tax 切s will not pay for themselves in even the most optimistic scenario. As the Center on Budget and Policy Priorities 写财政部发现，“从长远来看，使总统的皇冠手机app下载网址政策永久化，并通过未来减少支出来支付皇冠手机app下载网址政策，最终可能最终使经济产出（国民收入）增加多达0.7％。如果最终使永久性皇冠手机app下载网址最终导致经济产出水平提高0.7％，那么这种假定的额外经济增长的效果将仅抵消总统皇冠手机app下载网址成本的一小部分。”
-CEA主席Ed Lazear 告诉 the Washington Times in September 2006 that "We do not say that the tax 切s pay for themselves."
Presumably these people are not biased against conservatives or tax 切s. And yet their findings and conclusions are ignored, and the magical thinking persists.

2) 的chair of CEA from 2003-2005, 格雷格·曼考：“一些供应方喜欢声称税收的扭曲效应 如此之大，以至于提高税率会减少税收。最喜欢 经济学家，我认为该结论对大多数加税都不可信， 我怀疑鲍尔森先生也不会。”
3) He's right! Hank Paulson, 衬套's last Treasury Secretary, 不: "As a general rule, I don't believe that tax 切s pay for themselves."
4）该意见得到了 安德鲁·桑威克, Chief Economist on Council of Economic Advisers, 2003-2004: "No thoughtful person believes that this possible offset [the 衬套 tax 切s] more than compensated for the first effect for these tax 切s. Not a single one."...
5）...并且 爱德华·拉泽尔, chair of the Council of Economic Advisers in 2007: "I certainly would not claim that tax 切s pay for themselves."
