Question

You work for a marketing firm that has just landed a contract with Run-of-the-Mills to help them promote three of their products: penguin patties, raskels, and kipples. All of these products have been on the market for some time, but, to entice better sales, Run-of-the-Mills wants to try a new advertisement that will market two of the products that consumers will likely consume together.

As a former economics student, you know that complements are typically consumed together while substitutes can take the place of other goods.
Run-of-the-Mills provides your marketing firm with the following data: When the price of penguin patties increases by 5%, the quantity of raskels sold decreases by 4% and the quantity of kipples sold increases by 5%.
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.
1. Complete the first column of the following table by computing the cross-price elasticity between penguin patties and raskels, and then between penguin patties and kipples. In the second column, determine if penguin patties are a complement to or a substitute for each of the goods listed. Finally, complete the final column by indicating which good you should recommend marketing with penguin patties.
Relative to Penguin Patties
Cross-Price Elasticity of Demand Complement or Substitute Recommend Marketing with Penguin Patties (Yes or No)
Raskels
Kipples

Answer 1

Answer;

Raskels = 0.8 Substitute

Kipples = -1 Complement

Step-by-step explanation:

Cross-price

elasticity of demand , Complement

Raskels (-4%)/(-5%) = 0.8 Substitute

Kipples (5%)/(-5%) = -1 Complement

Recommended

Raskels No

Ripples Yes

Cross price elasticity = Percentage change in quantity demanded of a good/Percentage change in price of another good.

If it is positive, then it means that the good is a substitute and should not be advertised together.

And If it is complement, then the good is a complement and should be advertised together.
