巩固与刺激

伦敦——

任何知识体系都建立在某些假设之上,这些假设无须明言,因为它们是被那个知识团体的所有成员所接受的东西。经济学也隐含着此类“深刻”的公理,但是,如果我们不对它们给予仔细审视,政策制定者就可能误入歧途。这正是眼下发生在各个国家的事情:削减支出、降低预算赤字。

约翰·梅纳德·凯恩斯写作《就业、利息与货币通论》的主要目标就是向人们揭示当时经济学正统观念背后的深刻公理,根据这些公理,持久的大规模失业是不可能存在的。他向反对者发问:“持久的大规模失业是不可能发生的,因此政府提高就业水平的‘刺激’有害无益,这种说法的背后逻辑是什么?”为了回答这个问题,凯恩斯重写了传统的经济学理论,然后将其完全推翻。

    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.

    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.

    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.

    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.
