A new study on the link between financial speculation in commodity markets and food-price spikes shows that the model can be used to predict future food-price spikes, strengthening the case that financial speculators (fleeing the collapse of the housing market) art the root cause of the violent food-price swings that have been blamed for global starvation, riots and political instability.
The new paper -- M. Lagi, Yavni Bar-Yam, K.Z. Bertrand, Yaneer Bar-Yam, UPDATE February 2012 — The Food Crises: Predictive validation of a quantitative model of food prices including speculators and ethanol conversion -- was produced under the auspices of the New England Complex Systems Institute.
In the new study, predictions made by the researchers’ original model are compared to actual food prices between March 2011 and January 2012. Placed on a graph, the lines match closely, and do so despite spanning a major change in price trends at the last bubble’s peak.
“If you have a straight line, extend it and say, ‘Aren’t we predictive,’ it doesn’t give that much confidence,” said Bar-Yam. “If it changes direction, that’s a much more severe test of what’s happening.”
Both the European Union and United States are now considering whether and how to limit commodity speculation. In the U.S., such limits are required by the Dodd-Frank Act, but have been fiercely resisted by the financial industry.
It’s expected that the U.S. Commodity Futures Trading Commission will enact speculation limits by the end of 2012, though they might still be blocked in court. But even if the rules pass, they’re arguably weak, focusing on “position limits,” or caps on the maximum number of contracts a single speculator can hold. The rules won’t won’t prevent markets from being overwhelmed by speculation.
(But what's a little starvation and global upheaval when compared against the miracle of "enhanced liquidity"?)
Speculation Blamed for Global Food Price Weirdness
The mystery of the glorious fireball emitted by microwaved grapes (featured in my novel Little Brother) has been resolved, thanks to a paper in the Proceedings of the National Academy of Sciences in which Trent University researchers Hamza Khattak and Aaron Slepkov explain how they destroyed a dozen microwaves before figuring out that the grapes […]
The rise in a belief that the Earth is flat is bizarre and somewhat frightening, a repudiation of one of the most basic elements of scientific consensus. Texas Tech University psych researcher Asheley R. Landrum attended a 2017 flat earth convention and interviewed 30 attendees to trace the origins of their belief in a flat […]
Teams of researchers are developing sesame seed-size neuro-implants that detect brain activity that signals depression and then deliver targeted electrical zaps to elevate your mood. It’s very early days in the science and technology but recent studies suggest that we’re on the path. Links to scientific papers below. Fortunately, the goal is to develop tools […]
What do Facebook, Twitter, YouTube and Google all have in common? Somewhere in their framework, they all use MySQL, that most versatile (and free!) of database management systems. And they’re not alone. If your company or the one you’d like to work for wrangles data (and who doesn’t?), they’re going to need someone with a […]
There’s a reason you’re hearing about the gig economy in every other business story these days. More than ever, people are finding income from more than one source. And if you find the right one, a side hustle can do more than just pad your pockets – it can allow you to finally get paid […]
High-def cameras are available to anyone and for much less than they were just a decade ago. Even the phones in our pockets can be used to shoot and edit short films. It’s never been easier to be a filmmaker, providing you have the technique. Enter the Film & Cinematography Mastery Bundle, an online boot […]
