monotone hazard rate I'll talk more about this in a second then the the difference between these two scaled by n goes to zero okay so some comments on this first of all I want to point out so there's this is a really important restriction in the result and the proof of the result what ends up happening is that we need to look at sort of how the level of demand changes as you vary the pricing policy and it turns out that some condition on the valuation distribution is is sort of necessary it's a little bit looser than this it
