没有计划的人

发自纽黑文——在最近的美国总统大选期间,其民意调查始终显示经济——尤其失业率——是选民们关心的首要问题。来自共和党的挑战者——米特·罗姆尼(Mitt Romney)试图利用这一问题,他宣称:“奥巴马总统的计划并不凑效,他没有一个能推动经济的计划。”

然而巴拉克·奥巴马(Barack Obama)依然成功连任了。这个结果也许反映了经济在选举期间的轻微改善,正如1936年大萧条持续期间富兰克林·罗斯福(Franklin Roosevelt)击败来自共和党的阿夫尔·兰登(Alf Landon)时所发生的情况那样。但奥巴马的胜利或许也证实了大部分美国选民对经济现实的基本观感。

经济理论并不能为政策制定者开出一个明确的药方。对宏观经济学的专业判断一如既往地杂乱无章。由于不可能用受控的实验来测试政策,因此我们永远都不可能对宏观经济措施实施明确的检验。

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
