El tipo de cambio no es el único problema

MILÁN – Si miramos los patrones comerciales de los dos principales actores de la economía mundial, dos aspectos saltan a la vista. Uno de ellos es que mientras los Estados Unidos tienen un déficit comercial con casi todos los países, incluidos Canadá, México, China, Alemania, Francia, Japón, Corea del Sur y Taiwán, sin mencionar los países exportadores de petróleo, el déficit más grande lo tienen con China. Si los datos comerciales se volvieran a calcular tomando en cuenta el país de origen de los distintos componentes del valor agregado, el panorama general no cambiaría, pero sí las magnitudes relativas: mayores déficits de los Estados Unidos con Alemania, Corea del Sur, Taiwán y Japón, y un déficit dramáticamente más bajo con China.

El segundo aspecto es que Japón, Corea del Sur y Taiwán –todas hasta cierto punto economías de altos ingresos- tienen un amplio superávit comercial con China. Alemania ha equilibrado relativamente su comercio con China, que incluso ha registrado un modesto superávit bilateral en el periodo posterior a la crisis.

Los Estados Unidos tienen en un constante déficit comercial global que fluctúa entre el 3% y 6% del PIB. Sin embargo, mientras el total refleja déficits bilaterales con casi todos los países, el congreso estadounidense está obsesionado con China, y parece estar convencido que la causa principal del problema radica en la manipulación china del tipo de cambio del renminbi.

    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.

  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.
