Supply

The quantity of a good or service that producers are willing and able to offer for sale at various prices.

Demand

Consumer Surplus

The difference between the maximum price a consumer is willing to pay for a good and the actual price they pay.

Producer Surplus

The difference between the minimum price a producer is willing to accept for a good and the actual price they receive.

Calculating Consumer Surplus

Consumer surplus can be calculated by finding the area below the demand curve and above the market price.

Calculating Producer Surplus

Producer surplus can be calculated by finding the area above the supply curve and below the market price.

Factors Affecting Consumer Surplus

Factors such as changes in consumer preferences, income, and the prices of related goods can affect consumer surplus.

Factors Affecting Producer Surplus

Factors such as changes in production costs, technology, and the prices of inputs can affect producer surplus.

Dumping

The practice of selling goods in a foreign market at a price below their production cost, often to drive out competition and gain market share.

Balance of Trade

The difference between the value of a country's exports and the value of its imports.

Trade Surplus

A situation in which the value of a country's exports exceeds the value of its imports.
