Le prix de la biodiversité

DHAKA – Nous autres êtres humains partageons non seulement la planète avec une grande variété d’autres espèces, végétales, animales et microbiennes, mais notre survie dépend également précisément de ces espèces. Ainsi, est-il possible de déterminer la valeur économique associée à la préservation de l’environnement naturel ?

Certains crieront certainement au scandale face à l’idée de mettre un prix sur la biodiversité, considérant sa protection comme un impératif évident. Pour autant, elles admettront sans doute combien la lutte contre la mortalité et la souffrance humaine, en parallèle d’un approvisionnement en nourriture, en eau ainsi que de la possibilité d’une éducation pour tous, constitue un aspect vital.

La réalité, c’est que nous ne disposons tout simplement pas de ressources suffisantes pour réaliser tous ces objectifs. Un certain nombre de choix difficiles doivent être effectués. La bonne nouvelle, c’est que l’économie peut nous permettre de déterminer comment exploiter de la manière la plus bénéfique les ressources qui sont les nôtres.

    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.
