Elasticity Economics. This is because a competitive marketplace offers more options for the buyer. We all have some intuition for elastic and non-elastic materials. Unitary demand occurs when a change in price causes a perfectly proportionate change in quantity demanded.

I have never read any CFRP test results report, so I’m foggy here. Supply is elastic if the price elasticity of supply is greater than 1 (es > 1), unit elastic if it is equal to 1 (es = 1), inelastic if it is less than 1 (es 1), perfectly elastic when a small change in price changes the quantity supplied by an infinite amount (es = ∞) and perfectly inelastic when the quantity supplied is unaffected by a change in price (es = 0). This curve can hold good for non- perishable items. In economics, elasticity refers to a ratio of the relative changes in two quantities. has a constant elasticity coefficient.The elasticity is the ratio of the percentage change in the dependent variable to the percentage causative change in the independent variable, in the limit as the changes approach zero in magnitude. Economic justice 1. 2. However, if that same candy bar's price rose up to $4, most people would not buy the candy. When the prices of these goods go up, consumers will either decide they don't really need the goods, and won't buy any, or they will begin to substitute away from the goods, buying more of the cheaper substitutes.

In the short-term it may be difficult for consumers to find substitutes in response to a price change, but, over a longer time period, consumers can adjust their behavior.
