Calculating Price Elasticity of Demand: An Example. Let's say that we wish to determine the price elasticity of demand when the price of something changes from $100 to $80 and the demand in terms of quantity changes from 1000 units per month to 2500 units per month.
There are three determinants of the price elasticity of demand. They are: The Availability of Close Substitutes: If a product has many close alternatives, for example, fast food, then people tend to react strongly to a price increase of one firm’s fast food. Thus, the price elasticity of demand for this product is high.
Price elasticity refers to how the quantity demanded or supplied of a good changes when its price changes. In other words, it measures how much people react to a change in the price of an item. Price elasticity of demand refers to how changes to price affect the quantity demanded of a good. Conversely, price elasticity of supply refers ...
Price elasticity of supply (PES) works in the same way that PED does. Equations to calculate PES are the same (except that the quantity used is the quantity supplied instead of quantity demanded).
A good with perfectly inelastic demand would have a PED of 0, where even huge changes in price would cause no change in demand.
Unit elastic PES would mean that increases in the price will lead to proportionately equal increases in quantity supplied.
Elastic demand occurs when changes in price cause a disproportionately large change in quantity demanded. For example, a good with elastic demand might see its price increase by 10%, but demand falls by 30% as a result.
Using this formula is not ideal because the direction of the change in price or quantity can affect the number calculated for price elasticity.
A good with perfectly elastic demand would have a PED of infinity, where even minuscule changes in price would cause an infinitesimally large change in demand.
