As Loucuras Cambiais da China

BERKELEY – A 11 de Agosto, a China desvalorizou a sua moeda em 2% e reformou modestamente o seu sistema de taxas de câmbio. Este acontecimento não teve uma importância desmesurada, mas os mercados financeiros responderam como se tivessem sido atingidos por um meteorito. A reacção negativa não tem qualquer mistério: a desvalorização da China é um exemplo académico de como a política cambial não deve ser conduzida.

Uma das motivações do governo era, presumivelmente, proporcionar um impulso à economia Chinesa em desaceleração. Embora o sector dos serviços, responsável pela maioria dos empregos, se esteja a aguentar relativamente bem, a produção nacional de bens transaccionáveis, muitos dos quais são produzidos para exportação, está a decrescer acentuadamente. Os exportadores Chineses foram apanhados na tenaz da fraca procura externa e dos salários nacionais em rápido crescimento.

A desvalorização é o remédio experimentado e comprovado para estes males. Mas uma alteração de 2% no valor da moeda é demasiado baixa para fazer qualquer diferença, dado que os salários na indústria Chinesa estão a subir a uma taxa anual de 10%.

    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.
