La Banque centrale de qui ?

BERKELEY – D'une manière générale, depuis au moins 115 ans (et peut-être plus) – soit au moins depuis la publication de l'ouvrage Geldzins und Güterpreis en 1898 (Intérêt et Prix) par l'économiste suédois Knut Wicksell - les économistes sont divisés en deux camps sur la question de la définition et des prérogatives d'une banque centrale.

Le premier camp, que l'on appellera le camp des banques, considère qu'une banque centrale est une banque pour les banquiers. Ses clients sont les banques. C'est un endroit vers lequel les banques se tournent pour emprunter de l'argent quand elles en ont vraiment besoin et ses fonctions consistent à aider le secteur bancaire pour que les banques puissent faire leurs propres profits et mènent à bien leurs affaires privées. La banque centrale doit surtout s'assurer que la masse monétaire soit assez étendue pour éviter que le simple manque de liquidités, sinon l'insolvabilité, ne contraigne les banques à la faillite et à la liquidation.

L'autre camp, que l'on appellera le camp macroéconomique, considère que les banques centrales sont les gardiens de l'économie dans son ensemble. Le travail de la banque centrale consiste à faire respecter dans la pratique la loi de Say - le principe selon lequel la production est compensée par la demande, avec ni trop peu de demande pour acheter ce qui est produit (ce qui provoquerait le chômage), ni trop (ce qui provoquerait l'inflation) - parce que la loi de Say n'est pas tout à fait certaine en théorie. En d'autres termes, la responsabilité principale de la Banque centrale n'est pas de préserver la santé des entreprises qui composent le secteur bancaire, mais plutôt de maintenir le bon fonctionnement de l'économie dans son ensemble.

    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.
