In economics, the quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a particular price level. This concept is closely related to factors such as consumer preferences, income levels, and product availability. The quantity demanded is typically represented in a graphical form as a downward-sloping curve, with higher prices leading to lower demand and lower prices resulting in increased demand. Understanding the quantity demanded is crucial for businesses in determining production levels and pricing strategies to meet consumer needs effectively.
The Structure of Quantity Demanded in Economics
Quantity demanded refers to the amount of a good or service that consumers are willing and able to buy at a given price. Here’s a detailed explanation of the best structure for defining quantity demanded:
1. Relationship with Price
- The quantity demanded is directly related to the price of the good or service.
- Generally, when the price decreases, the quantity demanded increases (ceteris paribus).
2. Factors Influencing Consumer Demand
Besides price, several other factors can influence consumer demand:
- Income: Higher income leads to increased demand for normal goods.
- Preferences: Consumer tastes and preferences affect demand.
- Substitutes: Availability of substitutes can reduce demand.
- Complements: Availability of complements can increase demand.
- Expectations: Consumer expectations about future prices or income can impact demand.
3. Table of Demand Schedule
A demand schedule is a table that shows the relationship between price and quantity demanded, holding other factors constant.
| Price | Quantity Demanded |
|---|---|
| $10 | 50 |
| $20 | 40 |
| $30 | 30 |
4. Demand Curve
A demand curve is a graphical representation of the demand schedule. It plots quantity demanded on the y-axis and price on the x-axis. The curve typically slopes downward, indicating the inverse relationship between price and quantity demanded.
5. Market Demand
- Market demand represents the total quantity demanded for a good or service by all consumers in a market.
- It is the horizontal sum of individual demand curves.
6. Shifts in Demand Curve
Changes in factors other than price can cause the demand curve to shift.
- Increase in demand: Rightward shift (e.g., increase in income).
- Decrease in demand: Leftward shift (e.g., increase in the price of a substitute).

Question 2:
What factor primarily determines the quantity demanded for a product?
Answer:
The primary determinant of quantity demanded is the price of the product.
Question 3:
How is the relationship between quantity demanded and price typically represented?
Answer:
The relationship between quantity demanded and price is typically represented by a downward-sloping demand curve, indicating that as price increases, quantity demanded decreases.
