L'économie, sa vulgarisation et la crise

NEW-HAVEN –L'économie est à la mode, en témoigne le nombre de livres, d'articles, de blogs et de conférences qui suscitent l'intérêt de l'opinion publique.

J'ai récemment participé à un débat sur ce phénomène à l'occasion de la réunion annuelle de l'Association américaine d'économie à Denver. La discussion a mis en évidence un paradoxe apparent : l'engouement du public pour l'économie survient à un moment où il ne fait plus confiance aux économistes, la plupart d'entre eux n'ayant pas prévu la crise, la plus importante depuis la Grande dépression. Comment expliquer alors le succès des livres écrits par des économistes ?

Voici l'explication la plus pertinente que j'ai entendue : l'économie est devenue plus intéressante parce qu'elle ne donne plus l'impression d'être une discipline achevée. Il est sans intérêt de lire un livre ou un article qui explique que les meilleures prévisions économiques sont produites par des logiciels spécialisés qui s'appuient sur des modèles économiques que l'on ne peut comprendre si l'on n'a pas un doctorat en économie.

    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.
