For every copy an e-book would sell at $14.99, it would sell 1.74 copies if priced at $9.99. So, for example, if customers would buy 100,000 copies of a particular e-book at $14.99, then customers would buy 174,000 copies of that same e-book at $9.99. Total revenue at $14.99 would be $1,499,000. Total revenue at $9.99 is $1,738,000.
That seems like a hard won data point, I'm surprised they threw it out to the public domain. It makes intuitive sense to me though. I buy a lot of ebooks and when they're really cheap I just buy them immediately rather than track them somewhere to go and purchase when I have time to read them later. My kindle has probably a half dozen books to read on it at the moment, and I imagine if they were $20-30 each I wouldn't be that flippant about it.
