Ce n'est pas la fin de la crise !

NEW-YORK – On peut interpréter les crises financières comme le fait Nassim Taleb en disant que ce sont des "cygnes noirs", des événements imprévus et imprévisibles qui changent le cours de l'Histoire. Mais dans mon nouveau livre sur les crises financières, Crisis Economics, qui couvre non seulement la crise récente mais une douzaine d'autres tant dans les économies avancées que dans les marchés émergeants, je montre que les crises financières sont en fait prévisibles. Ce qui se passe maintenant, la seconde phase de la crise financière mondiale, était tout aussi prévisible.

Les crises sont la conséquence inévitable de l'empilement de vulnérabilités et de risques macroéconomiques, financiers et politiques : des bulles des actifs, des prises de risques excessives et un recours excessif à l'effet de levier, le boom du crédit, une politique monétaire relâchée, un manque de contrôle effectif et de régulation du système financier, la cupidité et des investissements trop risqués des banques et des autres institutions financières.

L'Histoire montre qu'au bout d'un certain temps les crises financières se métamorphosent. Celle que nous avons récemment subie a été initiée par une dette excessive et un recours excessif à l'effet de levier parmi les acteurs du secteur privé (les ménages, les banques, les institutions financières et les entreprises). Cela a abouti à un nouvel endettement externe du secteur public, alors que les plans de relance budgétaire et la collectivisation des pertes privées (les plans de sauvetage) ont accru dangereusement les déficits budgétaires et le volume de la dette publique.

    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.
