10 Questions
What does a high Price Elasticity of Demand (PED) indicate?
Consumers are sensitive to price changes.

It might not have a major effect on demand.
Why are companies interested in knowing the PED of their products?
To understand consumer behavior and anticipate demand.
What role does PED play in marketing and public policy decisions?
It helps in anticipating consumer behavior and price changes.
How does understanding PED help companies in resource allocation decisions?
It provides insight into consumer preferences and demand fluctuations.
What does the price elasticity of demand (PED) help us understand?
How consumers react to changes in product prices
If PED is greater than 1, how is the demand categorized?
Elastic
What happens to demand for a good if its price changes and PED is less than 1?
Demand changes slightly
Which category describes a product with PED equal to 1?
Unitary
Why is gasoline considered an inelastic good?
Because it has low price elasticity of demand (PED < 1)
Study Notes
The Elasticity of Demand: Understanding Consumer Sensitivity to Price
The concept of the price elasticity of demand (PED) is a fundamental principle in economics, helping us understand how consumers respond to changes in product prices. PED quantifies the responsiveness of demand for a good or service to price fluctuations. In simpler terms, it tells us how much the quantity of a product demanded changes when its price changes.
Elasticity Categories
Goods or services with high PED are elastic; a substantial change in price is met with a large change in demand. Conversely, goods with low PED are inelastic; a significant change in price leads to a small change in demand. PED has three categories:
- Elastic: If PED > 1, demand is elastic.
- Inelastic: If PED < 1, demand is inelastic.
- Unitary (or Unitary): If PED = 1, demand is unitary (or unitary elastic).
Calculating PED
The formula for PED is as follows:
[ PED = \frac{\text{Percentage Change in Quantity Demanded}}{\text{Percentage Change in Price}} ]
If the PED is greater than 1, the product is elastic. If it is less than 1, the product is inelastic. If PED is equal to 1, the product has unit elasticity.
Real-World Examples
Consider these examples:
- When gas prices rise, people might reduce the amount they drive, but not drastically. Therefore, gasoline has a comparatively low PED, making it an inelastic good.
- Conversely, if the price of ice cream increases, consumers might switch to other desserts or consume less ice cream. Ice cream has a higher PED, making it an elastic good.
- If the price of salt goes up, consumers may not change their salt consumption much. Salt has a low PED, making it an inelastic good.
Implications for Business
Companies are often interested in the PED of their products when setting prices and anticipating demand. For example, if PED is high, a price increase may lead to significant drops in demand. If PED is low, a price increase may not have a major effect on demand.
Overall Importance
The PED is a vital economic concept, used to understand consumer behavior and the potential effects of price changes. It helps businesses strategize price setting and anticipate demand fluctuations and is a crucial tool in marketing, public policy, and resource allocation decisions.
