Demand functions for a straight-line demand curve take the following form: Quantity = a - (b x Price). where a and b are constants that must be determined for each particular demand curve. When price changes, the result is a change in quantity demanded as one moves along the demand curve.
Itâs a physical part of the economic equation. Demand curves always slope down. If you are into math, it means a demand curve will always have negative slope. What does this mean in the real world? As price goes down, people will demand more of something. No one is willing to pay higher prices for more quantity. But the real reason this is interesting is this paper by Dhananjay K. Gode and Shyam Sunder. Itâs a study of trading and efficient markets.
