Le temps de la clarté

JOHANNESBURG – Dans l’esprit de beaucoup, le terrorisme et le réchauffement climatique représentent les plus grandes menaces pour la planète. Aux États-Unis, l’administration Bush veut augmenter les financements consacrés à la sécurité des frontières et aux lois sur l’immigration de près de 20 %. Plus de 150 millions de dollars sont versés aux systèmes de transit de New York, du New Jersey et du Connecticut pour les aider à éviter et à réagir aux attaques terroristes.

Mais le terrorisme international tue au total environ 400 personnes chaque année. Combien serions-nous prêts à payer pour réduire ce chiffre de, disons, 25 % ? Un milliard de dollars, une centaine de milliards ?

À Hawaï, des décideurs se sont réunis pour évoquer un traité sur le réchauffement climatique destiné à remplacer le protocole de Kyoto. Les groupes de pression écologistes veulent que le prochain traité aille bien plus loin que Kyoto, qui coûte déjà au monde 180 milliards de dollars par an. Il se trouve que les tentatives de ralentissement du réchauffement climatique au moyen du protocole de Kyoto ou d’un traité similaire ne feront qu’une différence minuscule, retardant l’augmentation des températures de seulement sept jours d’ici 2100.

    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.
