Prendre au sérieux la croissance de la zone euro

LONDRES – J'ai quitté le monde de la finance internationale et de la prévision économique depuis plus de quatre ans. Pourtant une grande partie de ce que j'ai appris au cours de mes 30 années de travail à temps plein dans ce domaine influence encore ma manière de percevoir le monde. Une leçon a été de mesurer la performance économique et financière en la comparant à la fois au potentiel sous-jacent de l'entité et à la valorisation de ses performances sur le marché. L'application de cette approche aux principales économies donne lieu à des observations et à des possibilités étonnantes.

Tout d'abord, contrairement à la croyance populaire, la croissance mondiale n'a pas été particulièrement décevante jusqu'à présent durant cette décennie. De 2010 à 2016, la production mondiale a augmenté à un taux annuel moyen de 3,4 %, selon le Fonds Monétaire International. Cela est peut-être inférieur à la moyenne des années 2000-2010, mais supérieur au taux de croissance dans les années 1980 et 1990 : des décennies que l'on ne tient généralement pas pour décevantes d'un point de vue économique.

Une ventilation selon les performances de certains pays fait apparaître d'autres perspectives. En dépit d'importants traumatismes politiques, les États-Unis et le Royaume-Uni ont fourni les résultats attendus. La Chine, l'Inde et le Japon ont également eu une croissance proche de leur potentiel. Aucune économie majeure n'a considérablement dépassé son potentiel, ce qui est assez rare.

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Rage Against the Elites

    • With the advantage of hindsight, four recent books bring to bear diverse perspectives on the West’s current populist moment. 
    • Taken together, they help us to understand what that moment is and how it arrived, while reminding us that history is contingent, not inevitable

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
