Unnötige Instabilität

PARIS – Im normalen Leben überlässt man die Technik besser den Technikern. Ein Autofahrer muss - und will - nicht wissen, was unter seiner Motorhaube genau vor sich geht. Aber bei einer Panne hat er oft keine andere Wahl.

Dasselbe gilt auch für die Wirtschaft: obskure Themen bleiben den Spezialisten vorbehalten. Doch in den vergangenen Jahren wurde die öffentliche Debatte von Begriffen wie der Verbriefung von Krediten in Wertpapierform, Kreditausfällen und dem europäischen Zahlungssystem Target 2 bestimmt, von welchen die meisten noch nie etwas gehört hatten und auch nichts hören wollten. Dadurch wurden normale Menschen gezwungen, sich mit den entsprechenden Details auseinanderzusetzen.

Das gilt auch für den Begriff "potenzielles Produktionswachstum". Ursprünglich war dies ein Konzept von Ökonomen für Ökonomen, bei dem es darum geht, wann und um wie viel ein Staatsdefizit korrigiert werden muss. Jetzt wird es immer mehr zum Thema einer breiten Diskussion. Da es schon so weit gekommen ist, dass seine Unvorhersehbarkeit den Fiskalpakt der EU schwächt, ist der Moment gekommen, die Motorhaube zu öffnen und nachzuschauen, was da drinnen vor sich geht.

    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.

    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.
