美国的经济僵局

坎布里奇——美国似乎陷入了危险的经济停滞陷阱。共和党和民主党均拒绝在预算问题上让步,这让美国政府无法处理大规模财政赤字和快速上升的国民债务问题。事实上,国会预算办公室估计,国民债务将在未来十年内上升至GDP的82%,即2008年水平的两倍。

此外,这一估计是建立在十分乐观的经济增长和低利率假设上的。如果增长率没有那么高,名义利率没有那么低,则债务比率将在2021年突破100%,在2030年超过150%。

政府债务上升越来越快的一个主要原因是美国人口在迅速老龄化,这导致全民退休金和医保项目——社会福利和医疗保险(Social Security and Medicare)——成本节节攀升。大多数专家认为,欲限制债务增长,就必须降低这些“福利”项目占GDP的比重,同时提高税收占GDP的比重。

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
