The vertical supply curve and vertical demand curve show that there will be zero percentage change in quantity a supplied or b demanded, regardless of the price. This illustrates the case of zero elasticity or perfect inelasticity. The quantity supplied or demanded is not responsive to price changes.

The percentage of change in supply is divided by the percentage of change in price. The results are analyzed using the following range of values:. There are numerous factors that impact the price elasticity of supply including the number of producers, spare capacity, ease of switching, ease of storage, length of production period, time period of training, factor mobility, and how costs react. The price elasticity of supply is calculated and can be graphed on a demand curve to illustrate the relationship between the supply and price of the good.
Supply and Demand Curves : A demand curve is used to graph the impact that a change in price has on the supply and demand of a good. In economics, elasticity refers to how the supply and demand of a product changes in relation to a change in the price. In economics, elasticity refers to the responsiveness of the demand or supply of a product when the price changes.
The technical definition of elasticity is the proportionate change in one variable over the proportionate change in another variable. The price is a variable that can directly impact the supply and demand of a product. For elastic demand, when the price of a product increases the demand goes down. When the price decreases the demand goes up. Elastic products are usually luxury items that individuals feel they can do without. An example would be forms of entertainment such as going to the movies or attending a sports event.
A change in prices can have a significant impact on consumer trends as well as economic profits. For companies and businesses, an increase in demand will increase profit and revenue, while a decrease in demand will result in lower profit and revenue.
In moving up the supply curve from left to right, each increase in quantity of 30, from 90 to to to , is equal in absolute value. However, in percentage value, the steps are decreasing, from Consider the price changes moving up the supply curve in Figure 4.
However, if the price changes are measured in percentage change terms, they are also decreasing, from Along the constant unitary elasticity supply curve, the percentage quantity increases on the horizontal axis exactly match the percentage price increases on the vertical axis—so this supply curve has a constant unitary elasticity at all points.
Infinite or perfect elasticity refers to the extreme case where either the quantity demanded or supplied changes by an infinite amount in response to any change in price at all. Zero elasticity refers to the extreme case in which a percentage change in price, no matter how large, results in zero change in quantity. Constant unitary elasticity in either a supply or demand curve refers to a situation where a price change of one percent results in a quantity change of one percent.
Can you think of an industry or product with near infinite elasticity of supply in the short term? That is, what is an industry that could increase Qs almost without limit in response to an increase in the price?
