The Unsustainable College Textbook Bubble
Kevin "Angus" Grier points out that Greg Mankiw's new textbook (6th edition) has a list price of $238.95, but sells at a discount for "only" $191.16 on Amazon; same price as the Gwartney economics textbook. Hey, isn't that "collusion" or "price fixing?"
As Angus comments: "These days, given that you could make yourself a pretty good free principles text just by downloading relevant Wikipedia entries, I don't see how these rents can be sustained over the long run (I am aware that not all or perhaps not even a majority of the rents are going to the authors)."
In other words, there's an unsustainable college tuition textbook bubble that makes the recent "housing bubble" almost unnoticeable by comparison (see chart above), and those rents, just like 2007 home prices or 1995 AT&T long distance charges, probably can't be sustained.
