为挽救增长节约资源

纽约-调和全球经济增长-特别是发展中国家的经济增长-与全球能源、粮食、土地和水不断强化的供应制约的矛盾,是我们时代的一个重大课题。因为需求的增加与有限的全球供应相比,差距越来越大,所以商品价格在全球范围内暴涨,不仅仅是像食品和能源这样饱受关注的商品,而且还有金属、耕地、淡水以及其他对增长至关重要的要素。在油价每桶135美元以及去年以来谷物价格翻番的压力下,全球经济已经在放缓。

现在需要一个新的全球增长策略来维持全球经济进步。基本问题是,现在全球经济体如此庞大,它正在触及以前从未触及的界限。全球有67亿人口,并且持续以每年增加750万人的速度增长,特别是在世界上最贫穷的国家人口增长迅速。按照世界不同地区的价格水平调整后,人均年度产出大约是1万美元,这意味着总产出大约为67万亿美元。

当然,在富裕国家和最贫穷的国家之间有巨大的差距,在富裕国家每人大约是4万美元,在最贫穷的国家每人是1千美元或更少。但是许多贫穷国家,最出名的是中国和印度,通过利用最尖端的技术,在最近几年经济已经获得了巨大的增长。结果,全球经济在最近几年以大约每年5%的速度增长。如果这一势头持续,全球经济规模将在14年内翻番。

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Rage Against the Elites

    • With the advantage of hindsight, four recent books bring to bear diverse perspectives on the West’s current populist moment. 
    • Taken together, they help us to understand what that moment is and how it arrived, while reminding us that history is contingent, not inevitable

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
