The book touches lightly upon advertising and how it can affect demand:

This strikes me as a very important subject, one that I heard little about in my (limited) economics courses. Anyone know of good references to how economics treats the ability of firms to affect demand?

Nearly every company has a marketing department. Some of the largest companies on the planet make all their money from other firms' desire to influence demand.

Is there any work at the intersection of evolutionary psychology, economics, and advertising?
