G0世界

纽约——当今世界,从理论上讲,全球经、政治理大权握于G20手中。但实际上,全球领导力并不存在,G20内部纷扰不断,分歧严重,举凡货币与财政政策、汇率与全球经贸不平衡、气候变化、贸易、金融稳定、国际货币体系、能源、食品和全球安全问题莫不如此。说真的,各大国心里觉得这些问题是零和博弈而不是正和博弈。所以说,我们的世界本质上是个G0世界。

19世纪,英国牢牢掌握霸权,大英帝国供应全球公共品——自由贸易、资本自由流动、金本位和作为全球主要储备货币的英镑。20世纪,美国取而代之,建立美国统治下的和平(Pax Americana),向西欧、亚洲、中东和拉美的广大地域提供安全保障。美国也主宰了几个布雷顿森林机构——国际货币基金、世界银行以及后来的世界贸易组织,它为全球贸易和金融秩序定规,美元成为主要储备货币。

可是如今,美“帝国”相对衰落,财政负担过重。而中国这个崛起中的大国,不是自由民主政体,想搞国家资本主义,还是现行全球体系中的搭便车者,在贸易、汇率和气候变化问题上,不想分担提供全球公共品的责任。而且,虽然美元饱受非议,人民币还远远不是主要全球储备货币之一,更不用说主导性货币了。

  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.

    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.

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.
