​OBJECTIVES
  1. ​Define and Explain Price Elasticity of Demand

  2. ​Calculate the price Elasticity of Demand

  3. ​Illustrate by graphs, the degrees of Elasticity of Demand

​What is Elasticity?

​Generally, Elasticity is a measure of the responsiveness of something when something else changes. There are many different elasticities; here we’ll look at the price elasticity of demand.

​So what is Price Elasticity of Demand?

​A Measure of the responsiveness of consumers demand to a change in price. It tells by how much demand will change when price changes.

​

​The price elasticity of demand measures how consumers respond to a price change.

​HOW IS IT CALCULATED?

​​The price elasticity of demand is the percentage change in quantity demanded of a good divided by the percentage change in the price of that same good (and you must take the absolute value of the whole thing).

**ABSOLUTE VALUE REFERS TO THE VALUE OF THE NUMBER IGNORING THE SIGN.

​FORMULA

The first formula is for the price elasticity of demand and the second is to calculate the percentage change.

​

​The absolute value just means that you express the price elasticity of demand as a positive number .

HOWEVER, YOUR CALCULATIONS FOR PED WILL ALWAYS RESULT IN A NEGATIVE NUMBER, therefore you take the absolute value when interpreting the values.

Multiple Choice

The price elasticity of demand measures

1

the slope of a budget curve

2

how often the price of a good changes

3

the responsiveness of the quantity demanded to changes in price.

4

how sensitive the quantity demanded is to changes in demand.

12

Multiple Choice

The price elasticity of demand equals

1

the percentage change in the quantity demanded divided by the percentage change in the price.

2

the change in the quantity demanded divided by the change in price.

3

the percentage change in the price divided by the percentage change in the quantity demanded.

4

the change in the price divided by the change in quantity demanded
