空气污染的真正成本

巴黎—空气污染让人们少活好多年。它能引起巨大的疼痛和痛苦,成人和儿童都不能幸免。它还威胁粮食生产,而我们现在比以往任何时候都需要粮食养活更多的人。它不仅仅是一个经济问题;也是一个道德问题。

室外和室内都可能产生空气污染。对最贫穷家庭来说,来自燃煤和燃粪炉灶的室内烟尘的问题常常更加严重。随着经济的发展和电气化、机动化和城市化的开始,室外空气污染成为更大的问题。

我们已经拥有更加清洁的技术,有望大幅提升空气质量。但决策者总是目光短浅地纠结于行动的成本,而不是不作为的成本。经济增长和能源需求的增加将让空气污染物排放稳步增加,并迅速提高未来几十年中颗粒物(PM)和臭氧的集中程度,因此,这样的方针不可取。

    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.
