IF YOU CAN TRADE IT, YOU CAN ALLOCATE IT EFFICIENTLY.

The University of Chicago has this reputation as the place fun goes to die.  That might be harsh.

On Monday, a group of students from the University of Chicago stood outside the Chicago Mercantile Exchange—one of the world's largest and most diverse derivatives marketplaces—and called for the repeal of an obscure 1958 law that bans onions as futures products traded on U.S. exchanges.

Attracting an audience with a humorous jingle and amusing signs that included "Onions Deserve a Future," "Honk If You Want Free Onions," "Hot Girls Hedge Onions," and "Free Markets Feed Families," the student group, named For Our Futures, has a simple platform: a repeal of the 1958 Onion Futures Act, which prohibits anyone from trading in onion futures on commodity exchanges. (The law was amended in 2010 to ban motion picture box office receipts from being traded on commodity exchanges.) The viral campaign drew enough attention that Mike Selig—chairman of the Commodity Futures Trading Commission and a proponent of expanding the list of commodities traded on futures markets—was asked about the law in a media appearance.

American farmers produce about 6.75 billion pounds of onions a year, according to the National Onion Association, an industry trade group. While peers who grow cotton, wheat, corn, and soybeans can hedge against price swings by trading futures contracts, onion farmers have no such recourse under federal law. But, as the Agriculture Department's daily National Potato and Onion Report shows, onion prices are highly volatile and subject to wild swings, making them an ideal market for futures trading.

Futures markets are not well understood by people who haven't studied economics, and the prohibition of onion futures contracts has not protected cooks and diners from the sort of price volatility the economically ignorant often associate with futures contracts.

Maybe there's a business opportunity for Sophie Cunningham?

Prices fluctuate to allocate demand.  That's something Our Intellectual Betters often lose sight of.

A protest over onions sounds absurd, but it's a viral reminder to others in that age cohort of how far governments can go when given the slightest leeway to regulate an industry.

Instead of relying on outdated price points when planning future harvests, American onion producers could use resources like futures contracts that offer real-time market signals. All that would require—as the college kids state—is for federal lawmakers to "let the free market reign supreme."

Indeed.  Arbitrage opportunities exist, whether organized futures markets exist or not.
