Le roi Ludd est encore mort

CAMBRIDGE – Depuis l’aube de l’ère industrielle, on a toujours craint que l’évolution technologique n’entraine un chômage de masse. Une situation inenvisageable selon les économistes néoclassiques, qui prévoyaient que les individus finiraient par retrouver un emploi, même au prix d’une longue période d’ajustement douloureux. Cette prévision s’est globalement avérée exacte.

Deux cents ans d’innovation époustouflante depuis l’aube de l’ère industrielle ont permis une amélioration des niveaux de vie pour les gens ordinaires dans une grande partie du monde, sans que la courbe du chômage ne s’envole. Oui, il y a eu de nombreux problèmes, notamment l’émergence de profondes inégalités et des guerres de plus en plus terribles. Mais en moyenne cependant, les hommes vivent plus longtemps, de manière plus saine, et travaillent un nombre d’heures nettement inférieur dans une majeure partie du monde.

Mais on ne peut nier l’accélération que connait l’évolution technologique, qui crée potentiellement des écarts plus profonds et plus importants. Dans un célèbre article de 1983, le grand économiste Wassily Leontief s’inquiétait de ce que le rythme si rapide de l’évolution technologique moderne ne rende de nombreux travailleurs, incapables de s’ajuster, tout simplement obsolètes, comme ce fut le cas pour les chevaux après l’apparition de l’automobile. Des milliers de travailleurs sont-ils donc, tels les chevaux, destinés à l’abattoir ?

  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. 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.
