Looking for a book mentioned on NPR (or PRI)

My dad is looking for a book and since I'm the family librarian, he turned to me. Unfortunately, the description is awfully vague, so I'm turning to my fellow public radio groupies. Here's what I've got (from my mom):

"Dad is trying to track down a book. He heard the author interviewed on All Things Considered or The World a month or two ago. The subject of the book was how to use the internet in building your business."

Does anyone remember the story or have any good keywords that might help me find it?

Did you try checking out their website?

I did. I checked the websites of both ATC and The World and did archive searches on "business" and "internet" for the last couple of months, but nothing came up that looked right.

Sorry that was my best guess, hopefully someone else will give you a hand.

I heard a mention this morning about an economist named Richard Wall (Wahl?) who has a different take on economic models than the standard one. I itch to know more, but can't find anything here or on Google. Did anyone catch the reference in more context?

>5 2wonderY: Could it be Richard Wolff you heard mention of?

>6 lesmel: I'll bet that's it! YAY! I knew I could count on you! Thank you!
