诺贝尔经济学奖得主保罗·克鲁格曼
美国时间2025年4月10日（星期四），诺贝尔奖得主保罗·克鲁格曼和其他经济学家一起，对唐纳德·特朗普总统不断变化的关税政策以及那些认为他做得很好的人，发表了严厉的批评。
克鲁格曼在一篇名为《特朗普愚蠢、反复无常且软弱》的Substack文章中写道：“任何对关税，或者总体而言特朗普的经济政策表示一切正常的人，都应该远离尖锐物品，并且禁止操作重型机械。”
克鲁格曼表示，认为特朗普昨天在关税问题上的转变——他宣布在接下来的90天里，对每个国家征收10%的关税，对中国征收125%的关税——实际上改善了任何情况，这种想法是愚蠢的。他说，我们“仍然面临着发生重大金融危机的风险”，而且世界其他国家“现在知道特朗普既反复无常又软弱”。
他说，围绕特朗普行动制造的全球不确定性，对经济的危害和高关税一样大。
克鲁格曼写道：“那么现在事情解决了吗？根本没有。暂停期是90天。然后会发生什么呢？没有人，包括特朗普在内，有哪怕一点点的头绪。”
“如果你是一位企业主或高管，在接下来的几个月里，你会进行任何重大投资或做出长期承诺吗？”他问道，“我不会。”
克鲁格曼写道，研究发现，比这些税率更低的关税都会“给美国经济带来严重冲击”，他还提到了彼得森国际经济研究所的研究人员之前构建的一个经济模型，该模型假设特朗普将全面实施10%的关税，对中国仅实施60%的关税，他强调说：“特朗普暂停90天之后的关税制度，我认为仍然是对美国，而且也是对世界历史上最大的贸易冲击。”
本周早些时候，曾在拜登总统的财政部工作美国顶尖经济学家之一、芝加哥大学经济学教授布伦特·内曼在《纽约时报》的一篇专栏文章中表示，他震惊地发现特朗普政府在制定关税政策时引用了他的研究成果，并称他们“大错特错”。

4月10日，美国前财政部长珍妮特·耶伦也对特朗普的关税政策提出了严厉批评。她告诉美国有线电视新闻网：““这是我所见过的一届政府对一个运转良好的经济体造成的最严重的自我伤害。”
Paul Krugman: 'Trump Is Stupid, Erratic and Weak'. Lydia O'Connor on HUFFPOST, Thu, April 10, 2025.
Nobel laureate Paul Krugman joined other economists Thursday in delivering some harsh words for President Donald Trump’s shifting tariff policies and those who think he’s doing a good job.
“Anyone sounding the all-clear on tariffs, or Trump economic policy in general, should be kept away from sharp objects and banned from operating heavy machinery,” Krugman, one of the country’s top economists, wrote in a Substack post titled “Trump Is Stupid, Erratic and Weak.”
It’s foolish to think Trump’s pivot on tariffs yesterday ― when he announced he was now putting a 10% tariff on every country and a 125% tariff on China for the next 90 days ― has actually improved anything, Krugman said. We’re “still at risk of a major financial crisis” he said, and the rest of the world “now knows that Trump is weak as well as erratic.”
Global uncertainty around Trump’s actions is just as dangerous to the economy as high tariffs, he said.
“So are things settled now? Hardly. The pause is for 90 days. Then what happens? Nobody, Trump included, has the faintest idea,” Krugman wrote.

″[I]f you were a business owner or executive, would you make any major investments or long-term commitments over the next few months?” he asked. “I wouldn’t.”
Research has found that tariffs lighter than these would “impose a nasty shock on the US economy,” Krugman wrote, pointing to an earlier economic model researchers at the Peterson Institute for International Economics constructed assuming Trump would implement 10% tariffs across the board and just 60% on China.
“Trump’s post-pause tariff regime remains the biggest trade shock in U.S., and I think world history,” Krugman said.
Earlier this week, a top economist said he was was shocked to discover that the Trump administration had cited his research when formulating the tariffs, saying they got it “very wrong.”
“How on earth did it calculate such huge rates?” University of Chicago economics professor Brent Neiman, who worked for the U.S. Treasury Department under former President Joe Biden, wrote in a New York Times op-ed.
Former U.S. Treasury Secretary Janet Yellen also had harsh words for Trump’s tariff policy Thursday.
“This is the worst self-inflicted wound that I have ever seen in an administration impose on a well-functioning economy,” she told CNN.
