La larga vida del dólar

NUEVA DELHI – La actual crisis económica y los constantes déficits de los Estados Unidos hacen que cada vez más se ponga en duda el papel del dólar como divisa de referencia mundial. Las medidas que se han hecho recientemente para internacionalizar el renminbi chino han conducido a una anticipación del cambio inminente en el sistema monetario global. Muchos economistas destacados, incluidos los miembros de un panel de las Naciones Unidas, que encabeza el economista galardonado con el Premio Nobel, Joseph Stiglitz, están aconsejando un “sistema mundial de reservas” para sustituir la hegemonía del dólar. Sin embargo, la larga historia de divisas de referencia globales sugiere que los días del dólar como moneda líder no van acabar pronto.

En tiempos antiguos, India tuvo un gran superávit comercial con el imperio romano. Como escribió Plinio en el Siglo I, “No hubo un solo año en el que India no se llevara de Roma 50 millones de sestercios.” Ese desequilibrio comercial implicaba una fuga constante de moneda de plata y oro, lo que provocó escasez de estos metales en Roma. En vocabulario moderno, los romanos se enfrentaron a una restricción monetaria.

Roma respondió reduciendo el contenido de plata y oro (el antiguo equivalente de la monetización), que condujo a una inflación sostenida en el imperio. Sin embargo, el descubrimiento frecuente de monedas romanas en la India sugiere que la moneda romana se siguió aceptando internacionalmente mucho tiempo después de que resultara obvio que su contenido de oro o plata había disminuido.

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations.

  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.
