¿Por qué hay tan poca inflación en Estados Unidos?

CAMBRIDGE – ¿A qué se debe la coexistencia en Estados Unidos de flexibilización cuantitativa y estabilidad de precios? O, como oigo decir a menudo: “¿Por qué la gran emisión monetaria por parte de la Reserva Federal no provocó más inflación?”

Es indudable que la inflación viene manteniéndose en niveles muy bajos. En los últimos cinco años, el índice de precios al consumidor creció a un ritmo anual de apenas el 1,5%. Y la medida de inflación preferida por la Reserva Federal (el índice de precios para gastos de consumo personal, con exclusión de alimentos y energía) también creció a un ritmo de apenas el 1,5%.

En cambio, durante el mismo período la compra de bonos a largo plazo por parte de la Reserva Federal llegó a niveles nunca antes vistos: más de dos billones de dólares en bonos del Tesoro y títulos con garantía hipotecaria, es decir, casi diez veces el volumen anual de compra de la década anterior. Solamente en el último año, el stock de bonos en el balance de la Reserva Federal aumentó más de un 20%.

  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.

    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.
