Maria has decided always to spend one third of her income on clothing. a. What is her income elasticity of clothing demand? b. What is her price elasticity of clothing demand? c. It Marias tastes change and she decides to spend only one fourth of her income on clothing, how does her demand curve change? What is her income elasticity and price elasticity now?
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?
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?
Suppose that your demand schedule for pizza is as follows: a. Use the midpoint method to calculate your price elasticity of demand as the price of pizza increases from 8 to 10 if (i) your income is 20,000 and (ii) your income is 24,000. b. Calculate your income elasticity of demand as your income increases from 20,000 to 24,000 if (i) the price is 12 and (ii) the price is 16.
Suppose that your demand schedule for DVDs is as follows: Price Quantity Demanded (income = 10,000) Quantity Demanded (income = 12,000) 8 40 DVDs 50 DVDs 10 32 45 12 24 30 14 16 20 16 8 12 a. Use the midpoint method to calculate your price elasticity of demand as the price of DVDs increases from 8 to 10 if (i) your income is 10,000 and (ii) your income is 12,000. b. Calculate your income elasticity of demand as your income increases from 10,000 to 12,000 if (i) the price is 12 and (ii) the price is 16.
Suppose Sally buys exactly five bars of English toffee each week, regardless of whether the toffee bars are regularly priced at 1 or on sale for 0.50. Based on this information, what is Sallys price elasticity of demand for English toffee in this price range? a. 0 b. 1 c. Infinity d. Cannot be determined.
What are the major determinants of a products price elasticity of demand? Studies indicate that the demand for Florida oranges, Bayer aspirin, watermelons, and airfares to Europe are elastic. Why?
Isabella always spends $50 on red roses each month and simply adjusts the quantity she purchases as the price changes. What can you say about Isabella's elasticity of demand for roses?
(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?
Estimates presented in Exhibit 5 show that Android users have a higher price elasticity of demand for apps in the Google Play Store than do iPhone users in the Apple App Store. Why might Android users tend to be more sensitive to app prices than iPhone users? What categories or types of apps (for example, games/social media) do you think have the highest price elasticities?
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.
