The Demand Law States Quantity Demanded

Elasticity of demand is the relationship between the demands for a product with respect to its price. Generally, when the demand for a product is high, the price of the product decreases. When demand decreases, prices tend to climb. Products that exhibit the characteristics of elasticity of demand are usually cars, appliances and other luxury items. Items such as clothing, medicine and food are considered to be necessities. Essential items usually possess inelasticity of demand. When this occurs prices do not change significantly.

1. When the price of a product is increased 10 percent, the quantity demanded decreases 15 percent. In this range of prices, demand for this product is ( )

You are an economist advising Holden Australia about increasing their total revenue. How would knowledge of elasticity help you to make the correct decision?

b. EXPLAIN how the total revenue test can be used to determine if a demand curve is elastic or inelastic. Use two graphs with numerical examples in your response. ( ____/5)

Income elasticity of demand is used to measure how consumers respond to changes to their income and their buying power or demand of a product. To better understand how changes of income affect consumers decisions to either buy less of a specific product or more of a specific product we use the income elasticity formula. The income elasticity formula is to divide the percentage change of the quantity of a particular product demanded over the percentage of change in a person’s income. The answer will result in either a positive or negative coefficient with a threshold of zero. If the results are a positive coefficient then that specific product is considered a normal/superior good; if the results are a negative coefficient that product is considered an inferior good.

Elasticity of demand is calculated by ED=quantity demanded/decrease in price. If you reduce the price of milk by 6%, and that causes an increase of quantity demanded by 9% the demand for milk is elastic (ED= .09/.06 = 1.5).

14. When the price increases from $4 to $6 and the quantity demanded decreases by 2 units, the price elasticity of demand is

2.) Which curve(s) change and based on the lists in the text of what causes demand and supply to shift what are the causes of theses shifts? D1 changed moving leftward indicating a decrease in demand due to a technological change: a technological setback causes a decrease. This causes price to go down as well as the demand is lower.

Elasticity of demand is measured as the percentage change in quantity demand divided by the percentage change in price .

7. Which of the following must be true if a firm is experiencing economies of scale?

II. When price falls from 4 pounds to 3 pounds the demand for travel increases to 80,000 units- At the original market price of 4 pounds the demand for travel was 60,000 units generating revenue of 240,000 pounds. When the price is reduced to 3 pounds the resulting demand is 80,000 units and this also generates income of 240,000 pounds. When market price changes and the resulting revenue remains the same it can be said that price elasticity of demand is unitary in

Based on the above description, forms of elasticity will affect business decisions and pricing strategies differently depending on the nature and type of products or services being offered. Business organizations whose product offerings have elastic and perfectly elastic price elasticities of demand should not attempt to raise prices of their products because it will cause the quantity demanded and consequently total revenues to drop drastically. Businesses can there use the price elasticities of demand to determine whether the proposed changes in their prices will raise or reduce their total revenue. The following expression may be useful in helping business organizations to determine the impacts of elasticities on their total revenues based on the suggested price changes.

1) According to the Law of Demand, the demand curve for a good will A) shift leftward when the price of the good increases. B) shift rightward when the price of the good increases. C) slope downward. D) slope upward. Answer: C 2) An increase in the price of pork will lead to A) a movement up along the demand curve. B) a movement down along the demand curve. C) a rightward shift of the demand curve. D) a leftward shift of the demand curve. Answer: A 3) An increase in consumer incomes will lead to A) a rightward shift of the demand curve for plasma TVs. B) a movement upward along the demand curve for plasma TVs. C) a rightward shift of the supply curve for plasma TVs. D) no change of the demand curve for plasma TVs. Answer:

Cigarettes is produced to satisfy the growing population of smokers. Smokers are hooked to a substance called nicotine that is in a cigarette along with other harmful substances. Cigarette is a great product to be selling for the firm. As the customers(smokers) are addicted to nicotine , these firms can rely on them for continuous demand and they can easily increase supply. Therefore, the firms can easily monopoly the market and fix their own price.

Recall that the elasticity of demand, which measures the responsiveness of demand to price, is given by
