Jeremy Siegel: Interest Rates Look Stable, but Beware the China Bubble
The U.S. economy may be getting stronger, but that doesn't mean interest rates will go up when the Federal Reserve meets next week on January 31.

The key to defining these people as ‘customers’ is that each engages in an exchange relationship that adds value to the organisation providing the product or service. Consumers do not give any value to organisations – there is no exchange relationship. They use products and services, but do not buy them.
