There are strategies for calculating rate flexibility off demand, but probably one of the most popular steps ‘s the ‘commission method’, hence uses next formula:
Based on legislation out of consult (wherein a rise in price will result in a decrease in demand, and you can vice versa), the brand new PED algorithm are always establish a terrible effect. When the results of new formula is anywhere between 0 and you can -step one, the price of a product is alleged to-be inelastic, whereas due to get out of -1 otherwise down is short for inelasticity.
But not, as PED algorithm usually supplies a bad influence, the newest without indication will get too many – so it is forgotten. Thus a poor count is actually transformed into a confident amount, and you can a product is regarded as elastic whenever PED > step one.
