Definition
Supply refers to the total amount of a commodity or service that is available to consumers at various price levels over a specified period of time. It is a core principle in economics that determines how much of a good or service is made available to the market by producers.
Two Main Contexts:
- Market Supply: The amount of a commodity that producers are willing to sell at a given price.
- Supply Chain Management: The process of providing goods or services needed or desired by consumers.
Examples
- Agricultural Products: The total quantity of wheat that farmers are willing to sell at different price levels during a harvest season.
- Manufactured Goods: The number of smartphones a tech company is able to produce and offer in the market based on current production capacity and market demand.
- Utilities: The amount of electricity the power company supplies to households and businesses.
Frequently Asked Questions
What factors affect supply?
- Price of the Commodity: Higher prices can incentivize producers to supply more.
- Production Costs: Changes in production costs such as labor, raw materials, and overhead.
- Technological Advancements: Innovations can make production more efficient, increasing supply.
- Government Policies: Taxes, subsidies, and regulations directly impact supply levels.
- Market Conditions: Demand fluctuations, economic stability, and competitor analysis.
How does supply differ from demand?
- Supply: Refers to the quantity of a good that is available for sale.
- Demand: Refers to the quantity of a good that consumers are willing and able to purchase at various price levels.
What is the law of supply?
The law of supply states that, all else equal, an increase in the price of a good leads to an increase in the quantity supplied.
Related Terms
- Demand: The quantity of a product or service desired by buyers at varying price levels.
- Equilibrium Price: The price at which the quantity demanded by consumers equals the quantity supplied by producers.
- Elasticity of Supply: A measure of how much the quantity supplied changes in response to a change in price.
- Market Dynamics: The forces of supply and demand that shape the behavior of market prices over time.
