عدم استقرار بلا داع

باريس ــ في الحياة الطبيعية، من الأفضل أن تُترَك المسائل الفنية للفنيين. فمالك السيارة لا يحتاج ــ أو لا يرغب عادة ــ إلى تكليف نفسه عناء معرفة ما يجري بالضبط تحت غطاء المحرك. ولكن عندما تتعطل السيارة فإنه لا يجد خياراً آخر عادة.

وما يصدق على السيارات ينطبق على الاقتصاد: فالقضايا الغامضة للمتخصصين. ولكن في السنوات الأخيرة، ظهرت مواضيع لم يسمع بها الناس أو لم يهتموا بها من قبل ــ على سبيل المثال، التوريق، ومقايضة العجز عن سداد الائتمان، ونظام الدفع الأوروبي المعروف باسم "تارجت 2" ــ فَرَضَت نفسها على المناقشة العامة، الأمر الذي أرغم الناس العاديين على التعامل مع تعقيدات تلك القضايا.

والشيء نفسه بدأ يحدث مع فكرة "نمو الناتج المحتمل". فهذا المفهوم، الذي أنشأه خبراء الاقتصاد في الأصل من أجل خبراء الاستخدام، أصبح استخدامه لتحديد متى وإلى أي مدى يجب تصحيح الدين العام موضوعاً لمناقشة أوسع نطاقا. والواقع أن عدم جدارة هذا المفهوم بالثقة يضعف بدرجة خطيرة الميثاق المالي للاتحاد الأوروبي ــ الأمر الذي يجعل رفع غطاء المحرك والنظر تحته أمراً ضروريا.

  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.

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.
