多少发展数据算够?

内罗毕—科技的迅速进步极大地降低了收集数据的成本。太空、天空、实验室和实地传感器,以及新兴的众包机会和已得到广泛使用互联网和移动电话正在让人们获得从前无从获得的巨量信息。比如,如今非洲农村地区的小农轻点屏幕就可以了解天气预报和市场价格。

数据革命为改善个层面决策提供了巨大的潜力——不论是本地农民还是业务遍布全球的发展组织。但光是收集数据是不够的。还必须管理和评估信息——合理地完成这一任务可能远比收集数据更复杂、更昂贵。如果需要改善的决策从一开始无法得到合理的识别和分析,就极有可能让巨大的集体努力付诸东流或出现方向性错误。。

这一结论本身便是基于实证分析。比如,监测农业或环境管理项目能带来积极影响,这一观点的支持证据很弱。多个领域——包括环境政策、商业投资和网络安全——的量化决策分析表明,人们倾向于高估做出好决策所需要的数据量或误解需要的数据类型。

    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.
