萧条经济学

伯克利—十年前,2008年诺贝尔经济学奖得主保罗·克鲁格曼写了一本小书,名叫《萧条经济学的回归》,结果石沉大海,几无反响。

1997 至1998年发生的东亚经济危机激烈而短暂,一旦国际货币基金组织认识到软弱的政府不成其为问题,然后美国财政部长罗伯特·鲁宾又把纽约的银行空降到韩国的公司里,危机很快就化解了。不久之后,2000年到2001年互联网泡沫的破灭带来的不是萧条,而只是一场产量下滑,程度之轻,刚够用得上“衰退”这个词。

现在克鲁格曼携带着改写扩展过的新版书卷土重来。悲哀的是,这个时机堪称完美—如果要用“萧条经济学”的方法来思考的话,现在的情形可比1998年适合的多。

    China in the Lead?

    For four decades, China has achieved unprecedented economic growth under a centralized, authoritarian political system, far outpacing growth in the Western liberal democracies. So, is Chinese President Xi Jinping right to double down on authoritarianism, and is the “China model” truly a viable rival to Western-style democratic capitalism?

    Whither the Multilateral Trading System?

    The global economy today is dominated by three major players – China, the EU, and the US – with roughly equal trading volumes and limited incentive to fight for the rules-based global trading system. With cooperation unlikely, the world should prepare itself for the erosion of the World Trade Organization.

    The Globalization of Our Discontent

    Globalization, which was supposed to benefit developed and developing countries alike, is now reviled almost everywhere, as the political backlash in Europe and the US has shown. The challenge is to minimize the risk that the backlash will intensify, and that starts by understanding – and avoiding – past mistakes.

    A Better British Story

    Despite all of the doom and gloom over the United Kingdom's impending withdrawal from the European Union, key manufacturing indicators are at their highest levels in four years, and the mood for investment may be improving. While parts of the UK are certainly weakening economically, others may finally be overcoming longstanding challenges.

    The UK’s Multilateral Trade Future

    With Brexit looming, the UK has no choice but to redesign its future trading relationships. As a major producer of sophisticated components, its long-term trade strategy should focus on gaining deep and unfettered access to integrated cross-border supply chains – and that means adopting a multilateral approach.
