El futuro del dólar

CAMBRIDGE – La política económica estadounidense tiene como objetivo un dólar fuerte en casa y competitivo en el extranjero. Un dólar fuerte en casa significa una moneda que conserve su poder adquisitivo gracias a una tasa de inflación baja. Un dólar competitivo en el extranjero significa que otros países no deben aplicar políticas que deprecien artificialmente el valor de sus monedas para promover las exportaciones y desalentar las importaciones.

La meta del dólar fuerte en casa ha sido lo que ha guiado a la Reserva Federal al menos desde que Paul Volcker aplastó la inflación a principios de los ochenta. Aunque los Estados Unidos no tienen una meta de inflación formal, los mercados entienden que la Reserva Federal busca una tasa cercana al 2%. Y, si bien por ley la Reserva Federal debe asegurar un crecimiento sostenible además de una inflación baja, los funcionarios encargados de la política monetaria reconocen que el crecimiento sostenible requiere estabilidad de precios. Durante décadas, los funcionarios de la Tesorería han insistido en que “Un dólar fuerte es bueno para los Estados Unidos”. Pero ese eslogan nunca ha sido una guía para las actividades oficiales del país en los mercados internacionales.

La Tesorería no interviene en los mercados de divisas para apuntalar al dólar y la Reserva Federal no aumenta las tasas de interés a esos efectos. En cambio, los Estados Unidos subrayan ante los gobiernos extranjeros que un sistema de comercio global efectivo exige no sólo la eliminación de las barreras comerciales formales sino también la ausencia de políticas orientadas a provocar valores de las divisas que fomenten grandes superávits comerciales.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
