Diez preguntas sobre la FC

NUEVA YORK – La mayoría de los observadores considera necesarias a las políticas monetarias no convencionales, como la flexibilización cuantitativa (FC), para lograr que las anémicas economías actuales comiencen a crecer. Pero junto con esa percepción de necesidad, han comenzado a multiplicarse las preguntas sobre la eficacia y los riesgos de la FC. En especial, diez potenciales costos asociados con esas políticas ameritan atención.

En primer lugar, si bien una respuesta puramente «austríaca» (esto es, de austeridad) ante el estallido de las burbujas de activos y crédito puede conducir a una depresión, las políticas de FC que posponen excesivamente el necesario desapalancamiento en los sectores privado y público pueden crear un ejército de zombis: instituciones financieras zombis, hogares y empresas zombis y, finalmente, gobiernos zombis. Así que, en algún punto entre los extremos austríaco y keynesiano, es necesario eliminar paulatinamente la FC.

En segundo lugar, la FC reiterada puede ir perdiendo eficacia a medida que los canales de transmisión hacia la actividad económica real se van obstruyendo. El canal de los bonos no funciona cuando sus rendimientos ya son bajos; y el canal del crédito no funciona cuando los bancos atesoran liquidez y colapsa la velocidad. De hecho, quienes pueden tomar créditos (las empresas con elevadas calificaciones y los hogares en mejor posición) no desean hacerlo o no lo necesitan, mientras que quienes sí lo precisan –las empresas muy apalancadas y los hogares en peor situación– no pueden hacerlo por la restricción crediticia existente.

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations. But, as European Council President Donald Tusk has said, the most difficult challenge – forging a workable deal that secures broad political support on both sides – still lies ahead.

  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.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    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. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. 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.
