What is Elasticity? 🤔
Elasticity is a term in economics that measures how much the quantity demanded or supplied of a good or service responds to changes in other variables, such as price or income. Put simply, it’s the drama queen of economics: it reacts quickly when you change the stage—like a price tag!
Main Definition
Elasticity: A measure of how much the quantity demanded or supplied of a good or service changes in response to a change in price or other variables.
Elastic vs Inelastic
| Elasticity Type | Characteristics | Examples |
|---|---|---|
| Elastic | Quantity demanded/supplied changes significantly with price changes | Luxury goods, fast food |
| Inelastic | Quantity demanded/supplied changes little with price changes | Essential goods, salt |
Examples of Elastic Products 🍕📈
- Luxury Items: Such as fancy cars, jewelry, and vacations. If their prices go up, people might reconsider their choices or simply fly to the nearest beach for a staycation!
- Fast Food: If the price of burgers goes up too much, there’s always another burger joint that is more accommodating (and maybe tastier too!).
Related Terms
- Price Elasticity of Demand: Measures how responsive demand is to a change in price.
- Income Elasticity of Demand: Measures how demand varies with consumer income changes.
- Cross-Price Elasticity of Demand: Measures how the quantity demanded of one good responds to changes in the price of another good.
Elasticity Formula
Here’s a simplified formula you can hang on your fridge (or your calculator):
graph TD;
A[Price Change] --> B{Elasticity};
B --> C[|ED| > 1: Elastic];
B --> D[|ED| < 1: Inelastic];
B --> E[|ED| = 1: Unitary Elastic];

Frequently Asked Questions
Q1: How do I know if a product is elastic or inelastic?
A1: Look at substitutes! If there are lots of alternatives and you can pick one up instead, chances are it’s elastic. Think more options mean more freedom!
Q2: Why is understanding elasticity important for businesses?
A2: It helps businesses adjust prices according to demand and stay competitive. After all, nobody wants to be the last store selling flip phones when everyone else has smartphones!
Q3: Can elasticity change over time?
A3: Absolutely! Trends, consumer preferences, and even seasonality can transform a product from elastic to inelastic more swiftly than a Starbucks can serve thousands of pumpkin spice lattes in fall.
