Grade Inflation

[CyrilMorong]

Is grade inflation worse at higher priced colleges?  I can imagine that if a student flunks out at a higher priced college, that it costs that school more in revenue and that it might be hard to attract students if they have to pay alot of money and then work hard to get good grades. Has any research been done on this?

Also, over time has the number of slots in colleges and universities available been rising relative to the number of students applying to college?  If that were the case, would schools feel pressure to inflate grades if they are unwilling to cut price?
