Study Notes

Supply Concept

Supply is the quantity of a good or service producers are willing and able to sell at different prices during a specific time period.

What is Supply?

Supply is defined as the quantity of a good or service producers are willing and able to offer for sale at various prices during a specific time period.

Law of Supply

The law of supply states that, all other factors remaining constant, as the price of a good or service increases, the quantity supplied also increases, and vice versa.

Key Components of Supply

Quantity Supplied: The specific amount of a good or service producers are willing to sell at a particular price.
Price: A key determinant of supply; changes in price directly affect the quantity supplied.
Supply Curve: A graphical representation of the relationship between price and quantity supplied, typically upward sloping.
Determinants of Supply: Factors other than price that affect supply, such as input costs, technology, prices of related goods, expectations, number of suppliers, and government policies.

Determinants of Supply: Price of the Good

Direct Effect: As the price of a good rises, producers are generally willing to supply more because of the higher potential profits.

Determinants of Supply: Input Costs

Input Costs: Changes in input costs (labor, raw materials, machinery) directly affect supply. Higher costs decrease supply; lower costs increase supply.
Technology: Advancements in technology usually decrease production costs, increasing supply.

Substitute Goods in Production: If the price of a substitute good increases, producers may allocate resources to that good, thus decreasing the original good's supply.
Joint Products: When goods are jointly produced (e.g., beef and leather), an increase in the price of one often leads to an increase in the supply of the other.

Determinants of Supply: Expectations

If producers expect higher future prices, they may reduce current supply to sell more later.

Determinants of Supply: Number of Suppliers

An increase in the number of suppliers in the market generally increases supply.

Determinants of Supply: Government Policies

Taxes: Higher taxes on production decrease supply.
Subsidies: Government subsidies reduce production costs, increasing supply.
Regulations: Strict regulations often increase costs and decrease supply; deregulation often has the opposite effect.

Determinants of Supply: External Factors

Natural Events: Severe weather conditions, natural disasters, or pandemics can greatly impact supply.
Global Market Trends: Changes in global supply chains or international trade policies affect local supply.

Supply Curve: Key Features

Horizontal Axis: Represents the quantity supplied of a good or service.
Vertical Axis: Represents the price of a good or service.
Slope: The upward slope reflects the direct relationship between price and quantity supplied.
Movement Along the Curve: A change in price causes a movement along the supply curve (increase in price = increase in quantity supplied; decrease in price = decrease in quantity supplied).

Problem Solving

Supply function example, calculation of quantity supplied at different prices, and determining the price at which no products are supplied (Qs = 0).
