IMF's new head economist is imaginative realist
By Edward Hadas
July 21, 2015
What the International Monetary Fund needs most in its economic counsellor is imagination and realism. With Maurice
Obstfeld, who will take over the job from Olivier Blanchard in September, it has both.
Of course, the distinguished Berkeley professor, member of the U.S. president's Council of Economic Advisers and leading
textbook author has the needed technical skills. But conventional academic excellence is not enough to guide the international lender
as it negotiates the intricate politics of the apparently endless Greek crisis. Nor can the old dogma deal with the greatest contemporary
challenge to steady economic development: global financial excess.
Blanchard already moved the IMF well away from its former identification with the Washington Consensus, which was based
on an exaggerated confidence in free markets. His suggestion that the universally targeted inflation rate of 2 percent might be too low
was highly unorthodox. Obstfeld is likely to go further in the same direction.

Is France’s supermarket waste law heading for Europe?
By Hugh Schofield BBC News, Paris
Plans to introduce a French law that bans supermarkets from destroying unsold food and obliges them to give it to charity is
irritating retailers who say they already make a big effort to fight waste.
Under the law, stores of more than 400 sq m would have until July 2016 to sign contracts with charities or food banks, and to
start giving them unsold produce. It follows a media campaign run by a young centre-right politician, Arash Derambarsh, who says
he was outraged by the sight of homeless people last winter scrambling in supermarket bins. A local councillor in the Paris suburb of
Courbevoie, Derambarsh began his campaign by collecting the unsold food and handing it out to the needy. He then launched an
online petition, which helped create momentum for the new law.
While broadly welcoming the idea, charities are also wary about ending up with more food than they can handle. "This had
better not translate into a poisoned chalice," says Olivier Berthe, president of the Restos du Coeur (Restaurants of the Heart) charity.
"We cannot be made to accept donations we do not need. We cannot become rubbish dumps." Jacques Bailet, president of the
French Federation of Food Banks (FFBA), also says there is a risk charities will not be able to cope. "Our food banks are going to
need more staff, more lorries, more refrigerated rooms. But to get all that, we will need money - and money is pretty scarce these
days," he says.

Under our feet, cables carry data between our homes,
offices and data centers at a pace that can match the speed of light.
The data travels as light that runs through strings made of materials
like glass and plastic.
Researchers at the University of Maryland want to do away
with the cable altogether and just use air to guide the light. That's
not as simple as it sounds, because a laser sent through air will
spread apart and interact with particles, gradually losing its intensity
over time.
The research team instead caused patches of air to mimic
a fiber optic cable by creating tubes of dense air surrounded by
low–density air. In a fiber optic cable, a laser travels through a
string of glass. When it tries to leave the glass, it hits a wall that
reflects it back into the center, guiding it along the length of the
cable. The cable made of air works in the same way.
“It's like you could just take a physical optical fiber and
unreel it at the speed of light, put it next to this thing that you want
to measure remotely, and then have the signal come all the way
back to where you are," University of Maryland team lead Howard
Milchberg said in a release.
Signals that traveled through the air cable were 1.5 times
stronger than when they were sent through plain air. The team was
able to send them over a distance of three feet and is now interested
in pushing the range to 150 feet.
If the University of Maryland team succeeds, the air cables
could be used for communication in remote locations on Earth
where laying fiber optic cables is extremely difficult, or places
where it actually is impossible like space. NASA is already
experimenting with laser communication between the International
Space Station and Earth. The technique could also be used to probe
the Earth to make topographic maps or examine the chemicals
present in hard–to–reach places like the atmosphere or a nuclear
plant.
