I'm not quite sure where to post this question. Mods, please feel free to move it if it should not go here. Anyway, I'm looking at a situation with fixed supply (vintage items) and I'm trying to get a feel for how the demand curve equation varies with an increasing number of interested buyers (all else being equal and fixed). Obviously, I know which direction it goes, but mathematically speaking, how would one expect the demand curve equation to change? I'm sure this question has been investigated somewhere, but I'm not sure where to look. Seems to me that once everything else is fixed, one should be able "simply" to relate the change in price to the change in the number of buyers. P/P_0 = f(B/B_0) ?? Thanks for any help or reference that can be offered.
