Politique fiscale américaine : un accord équilibré

CAMBRIDGE – Le plan fiscal sur lequel le président Obama et l'opposition républicaine au Congrès se sont mis d'accord représente la bonne combinaison de mesures à court terme,  accompagnée d'un premier pas vers une politique budgétaire raisonnable à long terme. Le principal point de l'accord est le maintien des taux d'imposition d'impôt sur le revenu de 2010 pendant encore deux ans, sans engagement pour la suite.

Sans cet accord, les taux d'imposition de 2011 auraient été ceux qui étaient en vigueur avant les baisses d'impôt décidées par Bush en 2001, ce qui se serait traduit par une hausse d'impôt pour tous les contribuables - à hauteur d'environ 450 milliards de dollars en 2011 et 2012, soit 1,5% du PIB.

Comme depuis peu le PIB américain ne croit plus que de 2% par an et la consommation des ménages seulement de 1%, cela aurait sans doute précipité l'économie américaine dans la récession. On dit souvent que cet accord va stimuler l'économie, mais plus précisément il permet d'éviter une contraction budgétaire immédiate de grande ampleur.

    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
