Elasticity of demand

Measure of how quantity demanded responds to changes in price.

Definition

Elasticity of demand is the measure of how quantity demanded responds to changes in price. Founders reach for it when a vague conversation needs a shared, specific meaning. Name it clearly, then let the next decision — a hire, a price, a test, or a pass — follow from that meaning.

How the word shows up in a real conversation.

Two cofounders disagree until they define Elasticity of demand. Once they agree it means “Measure of how quantity demanded responds to changes in price”, the argument becomes a decision.

Common mistake

Using Elasticity of demand as a label instead of a fact. If you cannot point to the evidence — a number, a customer, or a written assumption — you are using the word as jargon.
