What kinds of issues can elasticity help us understand? What is the price elasticity of demand? How is it related to the demand curve? What is the price elasticity of supply? How is it related to the supply curve? What are the income and cross-price elasticities of demand? You You charge charge per per website, website, and and currently currently sell sell 12 12 websites websites per per month. Your Your costs costs are are rising rising including including the the opportunity opportunity cost cost of of your your time , time , so so you you consider consider raising raising thethe price price toto The The law law of of demand demand says says thatthat you you wont wont sell sell as as many many websites websites ifif you you raise raise your your price.
How How many many fewer fewer websites? How How much much will will your your revenue revenue fall, fall, or or might might itit increase? One type of elasticity measures how much demand for your websites will fall if you raise your price. Definition: Elasticity is a numerical measure of the responsiveness of Qd or Qs to one of its determinants.
We D We will will drop drop the the minus minus sign sign and and report report all all price price Q elasticities Q2 Q1 elasticities as as positive positive numbers. It doesnt matter which value you use as the start and which as the end you get the same answer either way! To learn the determinants of price elasticity, we look at a series of examples.
Each compares two common goods. The good for which Qd falls the most in percent has the highest price elasticity of demand. Which good is it? What lesson does the example teach us about the determinants of the price elasticity of demand? For which good does Qd drop the most? Breakfast cereal has close substitutes e. Lesson: Price elasticity is higher when close substitutes are available.
For a narrowly defined good such as blue jeans, there are many substitutes khakis, shorts, Speedos. There are fewer substitutes available for broadly defined goods.
There arent too many substitutes for clothing, other than living in a nudist colony. Lesson: Price elasticity is higher for narrowly defined goods than broadly defined ones. To millions of diabetics, insulin is a necessity. A rise in its price would cause little or no decrease in demand.
A cruise is a luxury. If the price rises, some people will forego it. Lesson: Price elasticity is higher for luxuries than for necessities.
Does Qd drop more in the short run or the long run? Theres not much people can do in the short run, other than ride the bus or carpool.
In the long run, people can buy smaller cars or live closer to where they work. Lesson: Price elasticity is higher in the long run than the short run. Perfectly Inelastic Demand - It is a situation where a change in price causes no change in the quantity demanded.
Unitary Elastic Demand - It is a situation when percentage change in quantity demanded is equal to the percentage change in price.
Greater than Unitary Elastic Price Elasticity of Demand is said to be Greater than Unitary Elastic when the percentage change in quantity demanded is greater than the percentage change in price. Less than Unitary Elastic - It is a situation when percentage change in quantity demanded is less than percentage change in price.
But you sell fewer units lower Q , due to Law of Demand. Which of these two effects is bigger? It depends on the price elasticity of demand. When D is elastic, Q 8 12 a price increase causes revenue to fall. In our example, suppose that Q only falls to 10 instead of 8 when you raise your price to When D is inelastic, Q a price increase 10 12 causes revenue to rise.
Does total expenditure on insulin rise or fall? Does luxury cruise companies total revenue rise or fall? Which effect is bigger? One side effect of illegal drug use is crime: Users often turn to crime to finance their habit. We examine two policies designed to reduce illegal drug use and see what effects they have on drug-related crime.
For simplicity, we assume the total dollar value of drug-related crime equals total expenditure on drugs. Demand for illegal drugs is inelastic, due to addiction issues. S1 Since demand P2 for drugs is inelastic, initial value P1 P rises propor- of drug- tionally more related than Q falls.
P and Q fall. P1 initial value Result: of drug- A decrease in P2 related total spending crime on drugs, and in drug-related Q2 Q 1 Quantity crime. Price elasticity of supply measures how much Qs responds to a change in P. Loosely speaking, it measures sellers price-sensitivity. Again, use the midpoint method to compute the percentage changes. Rule of thumb: The flatter the curve, the bigger the elasticity. The steeper the curve, the smaller the elasticity.
Five different classifications. Example: Supply of beachfront property is harder to vary and thus less elastic than supply of new cars. For many goods, price elasticity of supply is greater in the long run than in the short run, because firms can build new factories, or new firms may be able to enter the market.
The supply of new cars is elastic. Suppose population growth causes demand for both goods to double at each price, Qd doubles. For which product will P change the most? For which product will Q change the most?
Recall from Chapter 4: An increase in income causes an increase in demand for a normal good. Cross-price elast. Elasticity measures the responsiveness of Qd or Qs to one of its determinants. Price elasticity of demand equals percentage change in Qd divided by percentage change in P. When its less than one, demand is inelastic. When greater than one, demand is elastic. When demand is inelastic, total revenue rises when price rises. When demand is elastic, total revenue falls when price rises.
Demand is less elastic in the short run, for necessities, for broadly defined goods, or for goods with few close substitutes. Price elasticity of supply equals percentage change in Qs divided by percentage change in P. When its less than one, supply is inelastic. When greater than one, supply is elastic. Price elasticity of supply is greater in the long run than in the short run.
The income elasticity of demand measures how much quantity demanded responds to changes in buyers incomes. The cross-price elasticity of demand measures how much demand for one good responds to changes in the price of another good. Open navigation menu. Close suggestions Search Search. User Settings.

In economics, the demand elasticity elasticity of demand refers to how sensitive the demand for a good is to changes in other economic variables, such as prices and consumer income. Demand elasticity is calculated as the percent change in the quantity demanded divided by a percent change in another economic variable. A higher demand elasticity for an economic variable means that consumers are more responsive to changes in this variable. There are major three types of elasticity of demand, i. Price elasticity, Income elasticity and Cross elasticity. However, this lesson focuses only on price elasticity of demand.
