介绍： In his address at the White House ceremony, Trump praised the state of the US economy and gave much credit for it to the economic policies promoted by Laffer and put in practice by former President Ronald Reagan. Today our nation is stronger, our people more prosperous and the world a much better place because of the brilliance and boldness of Doctor Arthur Laffer. Laffer is best known for the so-called “Laffer Curve”, a drawing he once made on a napkin to illustrate the relationship between tax rates and the amount of tax revenue collected by the government. Art showed that if tax rates are too high, people stop spending and they stop investing. The result is less growth and lower tax revenues. The theory not originated by Laffer has been popular with Republicans. But experts say there is no conclusive study to prove it. Critics also point out that the US economy has grown in some periods when the top marginal tax rates were as high as 90 percent.
在白宫仪式上发表演讲时，特朗普赞扬了美国经济的状态，并表示美国经济能有今天，很大程度上归功于拉弗推动的经济政策以及前总统里根对政策的施行。今天，美国更强大了，美国人民更富裕了，世界更美好了，这都是因为亚瑟·拉弗博士的才智和勇敢。拉弗最为人所知的是“拉弗曲线”。他曾在一张纸巾上画过拉弗曲线，是为了讲解税率与政府税收之间的关系。该曲线表明，如果税率过高，那么人们就会停止消费、停止投资。结果就是增长下滑、税收减少。虽然拉弗并非该理论的创始人，但拉弗让该理论在共和党中颇受欢迎。不过，一些专家表示，目前还没有研究结论能证实这一点。一些评论家还指出，美国经济增长的时期是最高边际税率高达90%的时候。
