Question

Run-of-the-Mills provides your marketing firm with the following data: When the price of penguin patties decreases by 20%, the quantity of raskels sold decreases by 22% and the quantity of kipples sold increases by 7%. Your job is to use the cross-price elasticity between penguin patties and the other goods to determine which goods your marketing firm should advertise together.

Answer 1

Penguin patties and kipples should be advertise together.

Step-by-step explanation:

The cross-price elasticity formula is:

CPE= % Δq of good A/ %Δp of good B

The CPE of penguin patties and raskels is:

CPE= -22%/-20%

CPE= 1.1

If the CPE is positive, then both goods are substitutes, which means that an increase in price of on good will affect positively the quantity demanded for the other good.

The CPE of penguin patties and kipples:

CPE= 7%/-20%

CPE=-0.35

If the CPE is negative, then both goods are complementary, which means that an increase in price of one good will affect negatively de quantity demanded for the other good.

You should advertise complementary goods together because both could be positively benefited by advertising. If the demand for good A increases, it is probable that the demand for good B increases too. If you advertise substitute goods, people will always prefer one, then the advertising will only be effective for one of the good but not for both.
