欧美债务困境

帕罗奥图——富庶的欧洲和美国,资本主义+民主政体的王冠上的宝石,目前正在赤字和债务泥淖中愈陷愈深。原因是欧洲的福利国家已经不堪重负,而美国正在走在不堪重负的路上。欧洲在为防止金融危机蔓延作斗争,而美国则在忙于削减创纪录的赤字,它们的债务水平非常危险,已经到了威胁未来生活水平、束缚国内和国际政治制度的程度。评级机构在威胁将进一步下降信用评级;其他人则在想象欧元崩溃和/或美元全球储备货币地位的终结的情景。

据经济学家罗格夫(Ken Rogoff)和莱因哈特(Carmen Reinhart)估算,如果一国债务-GDP比率达到90%,那么该国增长前景就相当堪忧了。希腊的负债率已经超过了120%,意大利大约为100%,美国为74%(几年前还只有40%)并且在迅速向90%靠拢。IMF估计,负债率每升高10个百分点将导致经济增长率下降0.2个百分点。因此,40—50%GDP幅度的债务增幅将令西欧部分国家长期经济增长率腰斩,令美国长期增长率下降三分之一,将对整整一代人的生活标准带来严重打击。

更坏的是,银行损失负担迟早要被社会化,未来公共养老金和医保将入不敷出,而这一切通常都会在官方债务数字中被淡化。此外,次一级政府的财政问题(比如美国和西班牙情形)将向中央政府伸手要援助,这将进一步增加中央财政的压力。

    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.
