What is the formula for the price elasticity of demand? The percentage change in the A) quantity demanded divided by the percentage change in the price of a substitute or complement. B) quantity demanded divided by the percentage change in price. C) quantity demanded divided by the percentage change in income. D) quantity supplied divided by the percentage change in price.
Suppose the cross-price elasticity of demand between DVDs at Amazon.com and DVDs at Rakuten.com is 3.5. Based on this information, predict what happens when Amazon.com lowers its DVD prices by 10 percent. The quantity of DVDs demanded on Amazon.com will decrease by 35 percent. The quantity of DVDs demanded on Amazon.com will increase by 35 percent. The quantity of DVDs demanded on Rakuten.com will decrease by 35 percent. The quantity of DVDs demanded on Rakuten.com will increase by 35 percent.
Find an article in The Wall Street Journal or The Economist that was published after 12/1/23 describing a change in price or quantity or both in some market. Analyze the situation using economic reasoning. A reference must be provided for the article Has there been an increase or decrease in demand? Factors that could shift the demand curve include changes in preferences, changes in income, changes in the price of substitutes or complements, or changes in the number of consumers in the market. Has there been an increase or decrease in supply? Factors that could shift the supply curve include changes in costs of materials, wages, or other inputs; changes in technology; or changes in the number of firms in the market. Draw a supply-and-demand graph to explain this change. Be sure to label your graph and clearly indicate which curve shifts. If done neatly, you can draw the graph by hand and paste it in your document
Fill out the tables by calculating the price elasticity of demand and of supply (use the mid-point formula). Report elasticities with 2 decimals.

Suppose that your demand schedule for compact discs is as follows Quantity Demanded (income-$10, 000) 40 CDs Price $8 $10 $12 $14 $16 32 24 16 8 Quantity Demanded (income $12, 000) 50 CDs 45 322 30 20 12 a. Use the midpoint method to calculate your price elasticity of demand as the price of compact dises increase from $8 tp, $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. Use the midpoint method.
Assume that you work in a movie theater and you want to increase revenue at the theater after the pandemic. The pandemic has caused people to find many activities that are alternatives to going to the movie theater. Fill in the blanks below with the words that best complete the sentences: Because consumers have found more substitutes for going to the movie theater, price elasticity of demand for movie tickets is more likely to be [ elastic or inelastic ]. Because of this price elasticity of demand, you should [increase or decrease] the price of movie tickets if you want to increase revenue.
Consider the following demand schedule. Price Quantity Demanded $25 20 $20 40 $15 60 $10 80 $5 100 Complete the following table by calculating the price elasticity of demand between specified points and indicating whether the demand is elastic, inelastic, or unit elastic. (Hint: Use the midpoints formula.) Interval Price Elasticity of Demand Elastic, Inelastic, or Unit Elastic From P = $25 to P = $20 From P = $20 to P = $15 From P = $15 to P = $10 From P = $10 to P = $5
Identify a product or service for which you use on a regular basis. Discuss the product/service in terms of the Law of Demand from your perspective as the customer and consumer of the item. How does price impact your quantity demanded? In other words, what is your change in quantity demanded as a result in an increase or decrease in the product’s price? What are some shift factors of demand (anything other than price) that can adjust your overall demand for the product?
Suppose the own-price elasticity of demand for beef is -0.8 and the own-price elasticity of supply of beef is 0.9. Due to a newly introduced government policy, beef supply increases by 2% with no change in the demand for beef. Assuming that the current price for beef is 40/cwt and the quantity bought and sold is 2,000 cwt per day, find the new equilibrium price and quantity of beef (round your answers to two decimal places).
In the graph on the right, the demand for syrup has changed because the price of frozen waffles has risen from $3.00 to $3.50 per package. The cross-price elasticity of demand between frozen waffles and syrup is. (Use the midpoint formula and enter your response rounded to two decimal places. Be sure to include the minus sign if necessary.) syrup) Price (dollars per package 4.00- 3.75- 3.50- 3.25- 3.00- 2.75- 2.50- 2.25- 2.00-1.89 1.75+ 1.50- 1.25- 1.00- 0.75- 0.50 0.25- 0.00+ 0 Syrup S D₁ D₂ 6,000 7,0009,000 3,000 6,000 9,000 12,000 15,000 Quantity (packages of syrup per week)
The tomato crop is ruined by heavy rains. As a result, the price rises from $4 to $6 a box and the quantity demanded decreases from 1,000 to 600 boxes a week. Over this price range, what is the price elasticity of demand? The income elasticity for Burberry watches is 1.5. What would be the change in quantity demanded of Burberry watches if income quadrupled? A 2 percent increase in the price of milk causes a 4 percent reduction in the quantity demanded of chocolate syrup. What is the cross-price elasticity of demand for chocolate syrup with respect to the price of milk? Are the two goods complements or substitutes?
