基本商品高价中的一线希望

    剑桥--当今基本商品价格猛涨道出了特别是西方政治人物不愿让我们知道的现代生活中的一个基本事实,那就是世界自然资源是有限的,而且,随着亚洲和其他地方几十亿人口脱贫,西方消费者就得分享这些资源。还有一个真相就是,价格机制在分配自然资源上要比打仗好得多,而西方列强在上个世纪就为了争夺自然资源而开战。

    美国生物燃料补贴项目不得其法,正好表明了错误的应对办法。布什政府不仅不承认高昂的燃料价格是促进节能和能源创新的最佳途径,反倒为美国的农民提供巨额补贴用于种植生物燃料生产的作物。他们从来都不考虑这在用水和用地上都是极为没有效率的。

    而且,在碳氢化合物时代结束以前(我们没人会活到那一天),即使在最为乐观的情形下,美国和全世界还是主要依赖常规矿物燃料。最后还有重要一点,把大量农田分离用于燃料生产已经造成小麦和其他作物价格翻倍。好几个国家已经爆发了食品骚乱,现在是不是时候承认这一整个想法是一个用心良苦巨大错误呢?

    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.
