金融泡沫的难题

发自伦敦——在2008年金融危机的严重性逐渐明晰了之后,针对央行和监管者是否可以——以及应当——有更多举措去以阻止危机的辩论也逐渐升温。由美国前联邦储备委员会主席艾伦·格林斯潘为代表的传统观点认为,任何试图提前刺破金融泡沫的举动都是注定失败的。各国中央银行的大部分工作还是如何收拾残局。

刺破泡沫确实可能在不必要的情况下扼杀增长——并带来高昂的社会代价。然而也人对此不以为然:国际清算银行的经济学家认定,鉴于此次危机成本如此之大,善后工作如此漫长,一旦下次再看到流动性和信贷出现风险性积聚时,我们就必须采取一些先发制人的措施,。

对此两派人马在国际货币基金组织近日于秘鲁首都利马召开的会议上展开了激烈(但隐晦而礼貌)的交锋。对于那些文学爱好者来说,这让人想起乔纳森·斯威夫特的著名小说《格列佛游记》。格列佛发现自己夹在了两个部落的煮鸡蛋战争中间,其中之一认为应该从尖头一端敲开来吃,另一个则一心认定地只有蛋屁股才是勺子的绝配。

    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.
