衡量自由的价值

伦敦—可靠的经济统计数字是重要的公共品。它们是有效决策、商业规划和选民问责决策者的基础。

但我们用来衡量我们的经济的方法正在日益过时。我们用来作为估算基础的统计约定是五十年前制定的,当时的经济生产的是相对较为相似的实体商品。今天的经济已是面目全非,并在迅速变化中——这是技术创新、基于知识的无形资产价值提高和经济活动国际化的结果。

面对这些挑战,英国财政大臣奥斯本(George Osborne)十个月前要求我评估英国当前和未来统计需求。尽管我的研究以英国为中心,但进行切题的高质量经济统计的挑战对许多国家都是一致的。

    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

    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.

    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.
