In a music shop, a young man is leisurely browsing through the racks of CDs. A woman, evidently in a hurry, brusquely pushes past him. "Sorry!" he says, "Maybe I could help you---if you don't mind telling me what you're looking for." "Don't You Know Who I Think I Was?", she replies. "Pardon?" "Don't You Know Who I Think I Was?" Looking rather perplexed, he answers, "No, I have to say I don´t!" "Sorry, I should explain. You asked me what I was looking for. So I told you the title of the album. Some songs from the 80s."

Unfortunately they cannot find the album. "Fancy a coffee?" the woman asks. "Great idea", the man replies, "I´m Bob, by the way." "Pleased to meet you, Bob. I'm Alice."

This is how a story begins which will continue through the Information Economics book ...
