(Calculating Price Elasticity of
The price elasticity of demand by using a midpoint formula.
ConceptIntroduction:
Price Elasticity of Demand: It is the degree of responsiveness to change in quantity demanded due to change in price level.
Midpoint formula for measuring the elasticity of demand is given as follows:
Where,
Explanation of Solution
We have presented the information in following table:
Price (in $) | Quantity (in units) |
---|---|
$1 | 50 |
$0.20 | 70 |
By applying the mid-point formula, we get
On solving the above, we get,
e=0.25
Hence, elasticity of demand using midpoint formula is 0.25
Now, if the elasticity of demand remains constant along the demand curve, then a 10% rise in the price will reduce the quantity demanded. We can calculate the amount of reduction in quantity demanded in following way.
So, the quantity demanded will decrease by 2.5%

- 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.arrow_forwardWhat is the formula for line cross-price elasticity of demand?arrow_forwardSuppose you learned that the price elasticity of demand for wheat is 0.7 between the current price for wheat and a price 2 higher per bushel. Do you think that farmers collectively would try to reduce the supply of wheat and drive the price up 2 higher per bushel? Explain your answer. Assuming that they would try to reduce supply, what problems might they have in actually doing so?arrow_forward
- 1. 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 28 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? 2. 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 verify this through…arrow_forwardQuestion 1.

- A store that sells maize meal discovers that when the price of 1kg maize meal is R24 per kilogram, the quantity demanded is 306 kgs per week. When the price decreases to R21 per kg, then the sales increase to 340kgs per week. Use this information to answer questions 3.1.1 and 3.1.2 below: 3.1.1.

- Subject: Business economics Remaining: Q3) Colgate sells its standard size toothpaste for Rs. 25. Its sales have been on an average 8000 units per month over the last year. Recently, its competitor Sparkle reduced the price of its same standard size toothpaste from Rs. 35 to Rs. 30. As a result Colgate sales declined by 1500 units per month. Calculate the cross elasticity between the two products. What does your estimate indicate about the relationship between the two?arrow_forwardQuestion 4The Pear company sells a smart phone for $250. Its sales have averaged 8,000 units per month over the last year. Recently, its closest competitor Banana company reduced the price of its smart phone from $350 to $300. As a result, Pear’s sales declined by 1,500 units per month. (a) What is the cross price elasticity of demand between the Pear and Banana smart phone? Use the averaging formula. What does this indicate about the relationship between the two products? (b) If the Pear company knows that the price elasticity of demand for its phone is -1.5, what price would the Pear company have to charge to sell the same number of units as it did before the Banana company price cut? Assume that Banana company holds its price of its phone constant at $300. Use the averaging formula.arrow_forwardP1= $4.50 Q1= 45 P2= $5.00 Q2= 40 a) what is price elasticity of demand b) given the price elasticity of demand coefficient you have calculated.
