皮克提所未见的知识

美国剑桥—理论框架是伟大的,因为它们用简化的用语让我们能够理解复杂世界的基本面貌,这一点如同地图。但是,也和地图一样,它们的作用是有限度的。比如,公路地图不会告诉你现在的交通状况或更新高速公路修补情况。

理解世界经济的一个有用办法是通过托马斯·皮克提(Thomas Piketty)在其著名作品《二十一世纪资本论》(Capital in the Twenty-First Century)所提出的优美框架。皮克提将世界分成两个基本成分——资本和劳动力。两者都用于生产并分享果实。

两者间的主要区别在于你可以购买、拥有、出售资本,并且从理论上可以无限地积累资本,就像超级富豪们所做的那样。劳动力是个人能力的使用,你可以有偿使用,但不能拥有劳动力,因为奴隶制早就已经终结了。

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
