怎样拯救欧元?

纽约——有时候事情看上去并不会变得很糟,但实际上却并非如此。即就是欧元区一些看似“负责”的成员国也将面临更高的利率。而大西洋两岸的欧美经济学家们现在讨论的已经不是欧元能否生存下来的问题,而是如何确保欧元体系的崩溃只带来最小的动荡。

尽管欧洲各国领导致力于挽救欧元,但在维系欧元运作的必要措施方面,各国领导对此的认识缺陷却逐渐暴露出来。欧元体系建立伊始,主流观点认为维系欧元体系的运作只需在财政方面进行约束,即,各成员国的财政赤字或公共债务应与各国国内生产总值相适应。经济危机前,爱尔兰和西班牙仍有预算结余,并保持较低的债务值。然而,很快一切都化为乌有,两国都陷入财政赤字,债台高筑。所以,当今欧洲各国领导都指出控制各成员国的经常项目赤字才是当务之急。

如果真是这样,那么随着经济危机的蔓延,美国这个常年保持经常项目赤字的国家却成了全球投资者的避风港,就显得不合常理了。而欧盟将如何分辨政府为创造有利投资环境以及增加外国直接投资而造成的“良性”经常性项目赤字和“不良”经常性项目赤字呢?要想避免“不良”经常性项目赤字,那么对于私营部门的干预则应该远远大于欧元区建立时颇受欢迎的新自由主义以及单一市场原则所倡导的程度。

    The Brexit Surrender

  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.

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.
