当代金融黑暗之王?

伦敦—在普利策奖获奖作品《金融之王》(Lords of Finance)中,经济学家利雅卡特·艾哈迈德(Liaquat Ahamad)讲述了四位央行行长因为坚持金本位而“打碎世界”、引发大萧条的故事。今天的央行行长基本上有了一套新的传统智慧——关于宽松货币政策的智慧。货币决策者会再一次打碎世界吗?

正统货币政策不再奉金本位为圭臬。金本位导致20世纪20年代各大央行利率管理失当,引起全球经济萧条并成为第二次世界大战的祸根。但自2008年金融危机爆发以来,我们经历了一段前所未有的合作货币宽松时期,它的问题也许不亚于金本位。事实上,它对金融市场的巨大影响早已清晰可辨。

一阶影响显而易见。机构投资者难以在任何传统安全投资中获得正实际收益率。比如,寿险公司为了兑现保证回报率而焦头烂额。据瑞士再保险公司(Swiss Re)的最新报告如果政府债券以接近于“公平价值”的价格交易,2008—2013年美国和欧洲保险公司可以赚得400—800亿美元(假设其50—60%的投资配置给固定收益证券,这也是典型的做法)。对公共退休基金来说,这段时间增加1%的收益率每年能新增收益400—500亿美元。

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations. But, as European Council President Donald Tusk has said, the most difficult challenge – forging a workable deal that secures broad political support on both sides – still lies ahead.

    ROBERT J. BARRO vs. JASON FURMAN & LAWRENCE H. SUMMERS on the impact of the GOP tax  overhaul.


    • Congressional Republicans are finalizing a tax-reform package that will reshape the business environment by lowering the corporate-tax rate and overhauling deductions.

  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.
