Le pouvoir des réseaux

CAMBRIDGE – Etant donné notre environnement (téléphones portables, ordinateurs et sites Internet tels que MySpace, Facebook et LinkedIn), dire que nous vivons dans un monde de réseaux est un lieu commun. Ces réseaux divers offrent de nouvelles formes de pouvoir, toutes différentes dans leur exercice. Barack Obama l’a compris�; c’est en effet ce qui l’a aidé à asseoir sa victoire.

Obama n’était pas le premier homme politique américain à utiliser Internet. Il a cependant été le plus efficace à exploiter cette nouvelle technologie pour récolter des fonds de petits donneurs, stimuler et coordonner des volontaires et s’adresser directement aux électeurs. La question qui se pose désormais à lui est de savoir comment gouverner avec ces réseaux.

Les réseaux revêtent un aspect et une taille des plus variés. Certains permettent d’établir des liens solides, d’autres des liens faibles. Songez à la différence entre vos amis et vos connaissances. Il est nettement plus probable que vos partagerez de précieuses informations avec vos amis qu’avec vos connaissances. Mais les liens faibles sont plus étendus et fournissent des informations inédites, novatrices et non redondantes.

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
