DALLAS

No, I am not an environmental radical or an oil company executive. I am a generally conservative American automobile driver, and a trained economist. As an economist, I understand that price movements in free markets send signals to consumers. These signals speak more clearly than all the rhetoric Washington, D.C., can muster, and change behavior more effectively than the finest of moralizing.

And when it comes to oil, America’s behavior needs to change.
