Key Concepts

Supply Function

A supply function represents the relationship between the price of a good and the quantity of that good that suppliers are willing to produce and sell. It is a fundamental concept in microeconomics that helps determine how changes in market prices affect the output levels of firms.

Fixed Costs

Fixed costs are expenses that do not change with the level of output. They are incurred regardless of how much is produced, such as rent or maintenance costs, and play a critical role in profit calculations by contributing to total costs that must be covered by revenue.

Profit Function

The profit function is the relationship that shows how a firm’s profit is determined by the difference between its total revenue and total costs. In this function, total revenue is typically calculated as the product of price and quantity, while total costs include both fixed and variable costs.

Comparative Statics

Comparative statics is an analytical method used in economics to study how a change in an external parameter (such as the price of a good) affects the equilibrium outcome of an economic model. It is useful for examining the impact of changes in inputs or market conditions on variables like output and profits.
