Assume that a retailer sells 1000 six-packs of Pepsi per day at a price of $3.25/six-pack. You as an economic analyst, estimate that the cross-price elasticity between Pepsi and Coca-Cola is 0.6. If the retailer raises the price of Coca-Cola from $3.00 to $3.30/six-pack, how would sales of Pepsi be affected, ceteris paribus? Sales of Pepsi would not be affected at all Sales of Pepsi would rise by 30 six-packs Sales of Pepsi would rise by 60 six-packs а. b. с. d. Can't tell; insufficient information

Economists define normal goods as having a positive income elasticity. We can divide normal goods into two types: Those whose income elasticity is less than one and those whose income elasticity is greater than one. Think about products that would fall into each category. Can you come up with a name for each category?
Income Effects depend on the income elasticity of demand for each good limit you buy. If one of the goods you buy has a negative income elasticity, that is, it is an inferior good, what must be true of the income elasticity of the other good you buy?
(Other Elasticity Measures) Complete each of the following sentences: a. The income elasticity of demand measures, for a given price, the __________ in quantity demanded divided by the __________ income from which it resulted. b. If a decrease in the price of one good causes a decrease in demand for another good, the two goods are __________. c. If the value of the cross-price elasticity of demand between two goods is approximately zero, they are considered __________.
The Stopdecay Company sells an electric toothbrush for $25. 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?
(Calculating Price Elasticity of Demand) Suppose that 50 units of a good are demanded at a price of Si per unit. A reduction in price to $0.20 results in an increase in quantity demanded to 70 units. Using the midpoint formula, show that these data yield a price elasticity of 0.25. By what percentage would a 10 percent rise in the price reduce the quantity demanded, assuming price elasticity remains constant along the demand curve?
Using the following equation for the demand for a good or service, calculate the price elasticity of demand (using the point form), cross-price elasticity with good x and income elasticity. Q=82P+0.10I+Px Q is quantity demanded, P is the product price. P1 is the price of a related good, and I is income. Assume that P= $10, I = 100, and Px = 20.
What is the formula for the income elasticity of demand?
