Inestabilidad producto de la rigidez

Todo el mundo quiere estabilidad económica y muchos son reacios a abandonar ahora lo que ayer les dio estabilidad. Pero tratar de obtener estabilidad mediante la rigidez es ilusorio. La estabilidad del sistema financiero internacional hoy depende de la voluntad de los países con tipos de cambio rígidos de permitir una mayor flexibilidad.

Tras la crisis financiera internacional de 1997-1998, muchos mercados emergentes –a través de la depreciación de divisas, los rápidos aumentos en la productividad, o ambos factores—quedaron en posiciones muy competitivas. Los países con superávit significativos en cuenta corriente acumularon grandes reservas y fijaron (o manipularon mucho) sus tipos de cambio para apoyar los dos primeros objetivos que parecían asegurar la estabilidad externa.

La ironía es que en la crisis de 1997-1998 un sistema particular de tipos de cambio fijos falló cuando el capital salió. Sin embargo, la acumulación de reservas funcionó mejor, de muchas maneras, de lo que nadie hubiera imaginado –los países descubrieron que podían resistir perturbaciones considerables y el crecimiento fue impresionante tanto internamente como a nivel global. Así pues, en unos cuantos años, muchos países llegaron a la conclusión de que sus tipos fijos podrían funcionar bien si estaban apoyados por reservas oficiales suficientemente amplias. Surgió un nuevo orden en el sistema mundial de tipos de cambio.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts.

But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
