Study Notes
- Lesson 3 will address elasticity of demand and supply in basic microeconomics.
- The aim is to compare and contrast income elasticity of demand and elasticity of supply as well as identify the similarities between demand elasticity and supply elasticity.
Elasticity of Demand
- Measures the change in product demand relative to a change in its price.
- Elasticity of Demand = Percentage Change in Quantity Demanded / Percentage Change in Price
- Computing elasticity always requires using two decimal places.
- Percentage Change in Demand = [Quantity Demanded (2) - Quantity Demanded (1)] / [Quantity Demanded (1) + Quantity Demanded (2)] x 100%
- Percentage Change in Price = [Price (2) – Price (1)] / [Price (1) + Price (2) / 2] x 100%
- If elasticity of demand is negative, the absolute value is used and elasticities are expressed as positive numbers
Demand Schedule
- Example of demand schedule for PE t-shirts at your school on August 1, 2020:
- Price (Php) 300 = Quantity Demanded 10
- Price (Php) 250 = Quantity Demanded 20
- Price (Php) 200 = Quantity Demanded 30
- Price (Php) 150 = Quantity Demanded 40
- Price (Php) 100 = Quantity Demanded 50
Demand Curve
- A graph of the demand schedule that shows the relationship between the price and quantity demanded
- It slopes downward from left to right.
Types of Elasticity of Demand
- Perfectly elastic = % change in quantity divided by % change in price = ∞
- Elastic = % change in quantity divided by % change in price > 1
- Unitary = % change in quantity divided by % change in price = 1
- Inelastic = % change in quantity divided by % change in price < 1
- Perfectly inelastic = % change in quantity divided by % change in price = 0
Elastic Demand
- value is higher than 1
- Indicates a high responsiveness to changes in price
Inelastic Demand
- Value is lower than 1 (decimals)
- Indicates low responsiveness to price changes.
Unitary Demand
- Value is exactly 1
- Indicates proportional responsiveness of either demand or supply.
Perfectly Elastic Demand
- Value is infinite
- Response to price is complete and infinite.
Perfectly Inelastic Demand
- Value is 0/ Zero
- There is no change in quantity when price changes.
Elasticity of Supply
- The responsiveness of a supply of a good or service after a change in its market price.
- Elasticity of Supply = Percentage Change in Quantity Supplied / Percentage Change in Price
- Computing elasticity always requires using two decimal places.
Supply Schedule
- Example supply schedule for PE T-shirts at your school on August 1, 2020
- Price (Php) 300 = Quantity Supplied 50
- Price (Php) 250 = Quantity Supplied 40
- Price (Php) 200 = Quantity Supplied 30
- Price (Php) 150 = Quantity Supplied 20
- Price (Php) 100 = Quantity Supplied 10
- Supply Curve illustrating data from T-Shirt supply schedule slopes upward from left to right.
Types of Elasticity of Supply
- Elastic Supply Value is less than 1
- Products are considered sensitive to price changes.
- Luxury goods and non-necessary items fall into this category.
- Inelastic Supply Value greater than 1
- Product is not sensitive to price movements.
- Food and gas are examples of inelastic supply goods.
- Unitary Supply value is equal to 1
- The quantity supplied changes by the same percentage as the change in price.
- Perfectly Elastic Supply value is an infinite number.
- When a good's elasticity of supply equals infinity
- The good is said to have perfect elasticity.
- Perfectly Inelastic Supply value is equal to 0/ Zero.
- A change in price leads to no change in quantity.
