Suppose you observe that when the price of a particular vitamin supplement_ by 3%, the quantity purchased increased by 0.9%. This implies that this vitamin supplement is price in demand and that the price elasticity of demand is equal to _ ☑ rises; inelastic; 0.3 O O rises; inelastic; 0.9 falls; inelastic; 0.3 rises; elastic; 3 falls; inelastic; 0.9

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 is the formula for line cross-price elasticity of demand?

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?

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?

(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 __________.

What is the formula for the income elasticity of demand?

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.

Why is the supply curve with constant unitary elasticity a straight line?

Suppose you are in change of sales at a pharmaceutical company, and your firm has a new drug that causes bald men to grow hair. Assume that the company wants to earn as much revenue as possible from this drug. If the elasticity of demand for your companys product at the current price is 1.4, would you advise the company to raise the price, lower the price, or to keep the price the same? What if the elasticity were 0.6? What if it were 1? Explain your answer.
