Economics 101

Ever wonder what it really means when the Fed raises or lowers interest rates? Our guest, Charles J. Wheelan explains how it all works in his new book, "Naked Economics: Undressing the Dismal Science." Wheelan says the book is not a dummy guide, but written for smart people who either never studied economics or have only a vague recollection of doing so. Wheeler also writes for the Economist magazine. www.wwnorton.com. Originally aired 10/4/2002.
