Le Japon peut-il redémarrer ?

CAMBRIDGE – Les récentes mesures du Premier ministre japonais Shinzo Abe (augmenter de façon spectaculaire la stimulation monétaire, reporter une augmentation de l'impôt sur la consommation et programmer des élections anticipées à la mi-décembre) ont remis son pays à l'avant-garde d'un intense débat politique. Le problème est simple : comment des économies avancées vieillissantes peuvent-elles relancer leur croissance après la crise financière ? Sa solution ne l'est pas.

Il est maintenant clair que le premier train de réformes d'Abe (appelées « Abenomics ») a échoué à générer une inflation durable. Des espoirs de reprise durable ont fait place à deux trimestres consécutifs de croissance négative. La question est de savoir si les Abenomics 2.0 vont remettre l'économie japonaise sur la voie de la prospérité.

Mon point de vue est que les « trois flèches » des Abenomics 1.0 avaient fondamentalement vu juste : une politique monétaire qui « emploie tous les moyens » pour rétablir l'inflation, une politique budgétaire de soutien et des réformes structurelles pour stimuler la croissance à long terme. Mais bien que la banque centrale, dirigée par le Gouverneur Haruhiko Kuroda, ait rempli sa part du contrat, les deux autres « flèches » des Abenomics ont manqué leur objectif.

    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.
