Where do you think oil prices will be next year? Go ahead, pick a number—any number—and you can probably find an expert somewhere who agrees with you. Andy Xie, the chief Asian economist for Morgan Stanley, says oil prices are about to collapse—recent prices of about $60 a barrel are far too high to last. The oil analyst Matthew Simmons says hogwash—we'll soon be paying $100 a barrel. Other pundits have staked out much of the wide real estate between those predictions.
