Important information about Calculating the own price elasticity of demand
The demand schedule for the product 'xyz' is given below:
Price($) Quantity demanded
3 20
4 15
5 11
6 9
7 7
Task: Based on the above data, solve the problems given below:
Compute the point price elasticity of demand for an increase in the price from $5 to $6.
Compute the point price elasticity of demand for a decrease in the price from $6 to $5.
Why does the magnitude of price elasticity differ in a and b above, although the same set of price-quantity combinations are used to compute the price elasticity of demand? Is their an alternative method that can be used?
