巨型工程时代

华盛顿—我们似乎正在进入一个巨型工程新时代,各国,特别是G-20国家,动员私人部门大量投资数百万美元(乃至数十亿、数万亿美元)的基础设施项目,包括输油管道、大坝、水利电力系统和道路网络等。

目前巨型工程支出每年已高达6—9万亿美元,约占全球GDP的8%,这意味着这是“人类历史上规模最大的投资繁荣”。而地缘政治、对经济增长的追求、对新市场的渴望以及对自然资源的搜寻正在驱使跟多的资金进入大规模基础设施工程。在前所未有的工程扩张潮中,世界领导人和贷款人似乎忘记了过去的代价沉重的教训。

诚然,基础设施投资可以服务于真实需要,有助于满足粮食、水和能源需求的预期剧增。但是,除非巨型工程的兴起得到小心引导和管理,否则它们有可能适得其反并且不可持续。如果没有民主控制,投资者将把收益私人化而损失社会化,采取碳密集和其他对环境和社会有害的方针。

    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.
