Q2.
(a)
The table below reveals the cross-price elasticity of demand for several goods.
Cross-price elasticity of
demand
Goods pairing
Air conditioning unit with electricity usage
| Coke and Pepsi
McDonald's burgers and Burger King
burgers
| Butter and margarine
-0.34
+0.63
+0.82
+1.54
Required:
(i)
Explain the sign of each of the cross-price elasticity. Describe the
implication of the sign on the relationship between both items in the
table above.
(ii)
Compare the absolute values of the cross-price elasticities and explain
their magnitudes. Explain why the cross-price elasticity of McDonald's
burgers and Burger King burgers is less than the cross-price elasticity
of butter and margarine.
(iii) Use the information in the table to calculate how a 5% increase in the
price of Pepsi affects the quantity of Coke demanded.

1. Suppose that the quantity of root beer demanded declines from 103,000 gallons per week to 97,000 gallons per week as a consequence of a 12 percent increase in the price of root beer from $27. The price elasticity of demand is
2. When demand for a product goes from 100 to 200 and income goes up from $40,000 to $45,000 what is the income elasticity of demand?
3. The price of Good X increase from P100 to P150, the quantity demanded for Good Y decreased from 50 to 35.
Dashboard for Online Pricing
Online the timing and tailoring of prices to specific models of products is the key to successful pricing in online markets. And “Thanks to the ready availability of data in online markets, a pricing manager can easily approximate the elasticity of demands for the different products it sells online.” Assuming a 10 percent decrease in price increases sales by 25 percent, calculate the price elasticity of demand? If the wholesale price of the online product is $50 and sells at a price comparison site that charges $.50 per click and boasts a conversion rate of 5 percent (an average of 20 clicks are needed to generate a sale). What price should you charge for the product? What is the optimal markup on cost?
The authors assert that price sensitivity is affected by (1) product life cycles, and (2) numbers of competitors. In fact, “when the number of competing sellers doubles, a firm’s elasticity of demand is expected to double (and you should be able to…

In each case, determine whether supply is elastic, inelastic, perfectly elastic, perfectly inelastic, or unit elastic. a. Price falls from $2.25 to $1.75; quantity supplied falls from 600 units to 400 units. b. Price falls from $2.25 to $1.75; quantity supplied falls from 600 units to 500 units. c. Price falls from $2.25 to $1.75; quantity supplied remains at 600 units. d.

Its sales have averaged 8,000 units per month over the past year. Recently, its closest competitor, Decayfigh ter, reduced the price of its electric toothbrush from $35 to $30. As a result, Stopde cays sales declined by 1,500 units per month. What is the arc cross elasticity of demand between Stopdecays toothbrush and Decayfighters toothbrush? What does this indicate about the relationship between the two products? If Stopdecay knows that the arc price elasticity of demand for its toothbrush is 1.5, what price would Stopdecay have to charge to sell the same number of units as it did before the Decayfighter price cut? Assume that Decayfighter holds the price of its toothbrush constant at $30. What is Stopdecays average monthly total revenue from the sale of electric toothbrushes before and after the price change determined in part (b)? Is the result in part (c) necessarily desirable? What other factors would have to be taken into consideration?arrow_forward
