Price Elasticity of Demand measures how quantity demanded of a product responds to price changes. It's crucial for pricing strategies, demand forecasting, and policy-making. Factors like substitutes, necessity, consumer income, time frame, and brand loyalty influence elasticity. Understanding this helps businesses and policymakers make informed decisions.

Price Elasticity of Demand quantifies how the quantity demanded of a good or service responds to changes in its price
Formula
The Price Elasticity of Demand is calculated using the formula \(E_d = \frac{\% \Delta Q}{\% \Delta P}\), where \(E_d\) is the price elasticity, \(\% \Delta Q\) is the percentage change in quantity demanded, and \(\% \Delta P\) is the percentage change in price
Importance of percentage changes
The formula focuses on percentage rather than absolute changes, providing insight into the relative impact of price variations on the demand for a good or service
Price Elasticity of Demand is used in pricing strategies, demand forecasting, and marketing to understand consumer behavior and make strategic decisions
Goods with readily available substitutes typically exhibit elastic demand
Necessities and luxuries have different levels of elasticity
The amount of income spent on a good can affect its elasticity
Short-term and long-term effects can impact elasticity
The level of brand loyalty can influence the elasticity of a good
Luxury automobiles typically display elastic demand, meaning that a rise in price can lead to a substantial decrease in demand
Public transportation services often have inelastic demand due to the lack of viable alternatives
Mobile applications, with a plethora of substitutes and low switching costs, tend to have elastic demand
Essential medications typically exhibit inelastic demand because they are indispensable and lack substitutes
00
Define Price Elasticity of Demand.
Price Elasticity of Demand measures how quantity demanded of a good/service changes with its price.
01
What does elasticity less than 1 signify?
Elasticity less than 1 indicates inelastic demand, meaning quantity demanded is less responsive to price changes.
02
What is unitary elasticity?
Unitary elasticity means quantity demanded changes proportionally to price changes; elasticity equals 1.
