Just in case you weren’t worried about rising food prices, The New York Times has an article out that makes the food markets seem even more volatile. Apparently, identical bushels of corn, wheat, and soybeans are selling for two different prices on the derivatives and cash markets.

Now, I’m not an economist, but the first line of the article makes the whole thing sound freakish. From the article:

Economists note there should not be two prices for one thing at the same place and time. Could a drugstore sell two identical tubes of toothpaste, and charge 50 cents more for one of them? Of course not.

But, in effect, exactly that has been happening, repeatedly and mysteriously, in trading that sets prices for corn, soybeans and wheat — three of America’s biggest crops and, lately, popular targets for investors pouring into the volatile commodities market. Economists who have been studying this phenomenon say they are at a loss to explain it.

Whatever the reason, the price for a bushel of grain set in the derivatives markets has been substantially higher than the simultaneous price in the cash market.

When that happens, no one can be exactly sure which is the accurate price in these crucial commodity markets, an uncertainty that can influence food prices and production decisions around the world.

I’m not sure what all this means. Thoughts?
