Topic: 3.4 Types of Profit

Overview of Profit

  • Definition of Profit: Profit occurs when total revenue exceeds total costs.

  • Types of Profit:

    • Accounting Profit: Total revenue minus explicit costs.

    • Economic Profit: Accounting profit minus implicit costs.

    • Normal Profit: Occurs when economic profit is zero; also known as "breaking even."

    • Economic Loss: Occurs when total revenue is less than total costs (TR < TC).

    • Supernormal Profit: Profits exceeding normal profit, indicating a firm is covering all costs and earning more.

Examples of Profit Calculation

  • Coca Cola Example:

    • Total revenue from selling 3,000 bottles: $9,000.

    • Total cost of production: $5,000.

    • Accounting Profit: $9,000 - $5,000 = $4,000.

  • Graphic Designer Example:

    • Salary given up: $500,000.

    • Revenue from business: $500,000.

    • Implicit costs: $440,000.

    • Economic Profit: $500,000 - $440,000 = $60,000 (normal profit).

Sample Questions and Answers

  1. Ginny's Case:

    • Accounting Profit: $75,000 (total sales) - $75,000 (costs) = $0.

    • Economic Profit: $0 (normal profit).

  2. Aaron Judge's Case:

    • Total Revenue: $3,000,000 (from selling video games).

    • Total Cost: $1,200,000 (fixed + variable costs).

    • Accounting Profit: $3,000,000 - $1,200,000 = $1,800,000.

    • Economic Profit: $3,000,000 - ($1,200,000 + $40,000,000 opportunity cost) = -$38,200,000.

Key Terms to Review

  • Accounting Profit: Total revenue minus explicit costs; used for financial performance assessment.

  • Economic Losses: Occur when total costs exceed total revenue; indicates inefficiency.

  • Market Structures: Characteristics of a market that influence firm operations and competition (e.g., perfect competition, monopoly).

  • Monopoly: A market structure with a single seller dominating the market, leading to higher prices and reduced consumer welfare.

  • Supernormal Profits: Profits exceeding normal profit, attracting new firms into the market.
