La eurozona necesita algo más que QE

CAMBRIDGE – Si bien el Banco Central Europeo lanzó un programa mucho mayor de lo esperado de alivio cuantitativo (QE), hasta sus defensores temen que tal vez no baste para impulsar las economías reales, reducir el desempleo y bajar los ratios deuda-PIB de los gobiernos. Tienen razón de tener miedo.

Pero primero las buenas noticias: la expectativa del QE ya aceleró la caída del valor internacional del euro. El euro más débil estimulará las exportaciones de los países de la eurozona -aproximadamente la mitad de las cuales van a mercados externos- y, por ende, aumentará el PIB de la eurozona. La depreciación del euro también hará aumentar los precios de las importaciones y, en consecuencia, la tasa general de inflación, alejando a la eurozona un poco más de la deflación.

Desafortunadamente, tal vez no sea suficiente. El éxito del QE en Estados Unidos reflejó condiciones iniciales que eran muy diferentes de las que ahora vemos en Europa. De hecho, los países de la eurozona no deberían sesgar en sus esfuerzos de implementar reformas suponiendo que las compras de bonos del BCE resolverán sus problemas. Pero aun si estos países no pueden superar las barreras políticas a la implementación de cambios estructurales en los mercados laborales y de productos que sirvan para mejorar la productividad y la competitividad, sí pueden implementar políticas capaces de aumentar la demanda agregada.

    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.
