Demand refers to the amount of a good or service consumers are willing and also capable of buying at various price levels in an averaged time period. It is one of the most basic concepts in economics and critical to the determination of both market dynamics and of business pricing as well as production decisions. A company, policymaker, and even an economist will be in a better position to anticipate consumer behavior or set appropriate prices as long as they understand the demand clearly.
What is Demand?
Demand therefore means the readiness and ability of consumers to acquire a specified goods or services at a specified price during a particular period. There are many factors that determine the concept of demand, which include the price of the product in question, the consumer’s income, tastes, and preferences, and the price of related goods like substitutes and complements.
- Willingness to Pay: Consumers must be willing to pay for the good or service.
- Ability to Pay: Consumers must have the financial capacity to purchase goods or services.
- Time Frame: Demand is considered over a specific time period (e.g., daily, weekly, or annually).
- Quantity: Demand always refers to the quantity of goods that consumers are willing to buy, not just whether they are willing to buy at all.
In economic theory, demand is typically represented by a demand curve or demand schedule, which shows how the quantity demanded varies with price.
Types of Demand
There are different demands, and each type signifies and evidences different market conditions and consumer behaviors. Therefore, it is crucial to understand the difference between them for businesses that formulate the pricing and marketing strategy.
Individual and Market Demand
- Individual Demand: Refers to the quantity of a good or service that a single consumer is willing to buy at a given price.
- Market Demand: The total quantity of a good or service that all consumers in the market are willing to buy at a given price.
Joint Demand
This occurs when the demand for one product is tied to the demand for another complementary product. For example, the demand for cars increases the demand for gasoline.
Derived Demand
Derived demand occurs when the demand for one product is derived as a result of demand for another. For example, demand for steel derives from demand for a car because one of the primary inputs in making a car is steel.
Composite Demand
It occurs when the use of a product is composite, so that its demand arises through various uses. Coal can be used for both electricity generation and for steel production; therefore, the demand for coal reflects its composite uses.
Price and Income Elastic Demand
Elastic Demand: When demand is sensitive to price changes, meaning a small change in price leads to a significant change in quantity demanded.
Inelastic Demand: When demand is less responsive to price changes, meaning consumers will continue to buy the product despite price fluctuations.
Factors Affecting Demand
Numerous factors affect demand, and these variables can shift the demand curve either to the left (decrease in demand) or right (increase in demand).
- Price of the Product: The price of a product is what primarily influences demand. Generally, when the price of a product increases, it follows that the quantity demanded decreases, and vice versa (the Law of Demand).
- Income of Consumers: With changes in the income of consumers, their demands become directly influenced. An increase in income implies that consumers have all the money to spend and purchase more goods and hence an increase in demand. Conversely, a decrease in income necessarily means that demand shall be reduced.
- Substitute Goods: If the price of a substitute good (like tea and coffee) is high, then people may shift to the cheaper one of the two, which in turn would increase its demand.
- Complementary Goods: If the price of the complementary goods (like printers and ink cartridges) goes down, both types of commodities are expected to increase.
- Consumer Preferences: An alteration in consumer tastes or preferences are basically driven by change in trends, advertisements, and cultural shifts, which can be a strong force on demand.
- Expectations of Future Prices: If consumers expect prices of a good to rise in the future, they buy more now and thereby increase current demand. But if they expect prices to drop then they would wait until further into the future to purchase, thereby reducing current demand.
- Number of Consumers: The more people there are or the greater the number of consumers, the higher the demand for goods and services.
Demand Schedule
A demand schedule is a table showing the quantity of a good for which consumers are willing to buy at different price levels. It therefore presents a direct relationship between price and quantity demanded. It serves as a tool to represent the Law of Demand.
Example of a Demand Schedule:
| Price of Good (₹) | Quantity Demanded (Units) |
| 100 | 50 |
| 90 | 60 |
| 80 | 75 |
| 70 | 90 |
| 60 | 110 |
The demand schedule above shows that as the price of the product decreases, the quantity demanded increases, consistent with the Law of Demand.
Demand Curve
A demand curve is a graph used to represent the demand schedule. The curve plots a relationship between price and quantity demanded, price on the vertical axis, and quantity on the horizontal axis. Most of the time, the demand curve slopes downward from left to right, meaning as the price of a good declines, the quantity demanded increases. Characteristics of a Demand Curve
- Downward Slope: The curve slopes downward, reflecting the inverse relationship between price and quantity demanded.
- Shift in Demand Curve: Factors like income changes, preferences, or the price of related goods can cause the entire demand curve to shift to the right (increase in demand) or left (decrease in demand).
Conclusion
The demand concept in economics is central for the explanation of consumer behavior and market dynamics. In application, firms and public authorities make use of demand analysis to predict the likely effect that changes in any of these influences – including price, income, and others – will have on purchases by consumers. In summary, knowledge of the types of demand, factors influencing demand, and concepts, such as the demand schedule and demand curve, reveals important information about how markets work and how businesses can improve pricing strategies in meeting consumer needs.
