En effet, du moins dans le domaine de l’économie financière, une version douteuse de la théorie de l’équilibre devint prédominante dans les années précédant la crise financière, dépeignant la complétude des marchés comme la solution à tous les problèmes, et la sophistication mathématique découplée de la compréhension philosophique comme la clé d’une gestion de risque efficace. Des institutions comme le Fond Monétaire International, dans son Rapport sur la stabilité financière dans le monde (GFSR), présentait une version confiante d’un système s’auto-équilibrant.

    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.
