    • Refers to statements or ideas based on judgments about what ought to be.

    • Example: If government uses tax money to build homeless shelters, it is normative.

  • Positive Economics:

Circular Flow Model

  • Circulation of Money:

    • Households provide factors of production (labor) to firms.

    • Firms provide goods and services to households in exchange for money.

  • Resource Markets vs Product Markets:

    • Resource Market:

    • Suppliers: Households.

    • Demanders: Businesses.

    • Product Market:

    • Suppliers: Businesses.

    • Demanders: Households.

Production Possibilities Curve (PPC)

  • Concepts Illustrated by PPC:

    • Attainable but inefficient (point A), maximum efficiency (point B), and unattainable (point C).

  • Efficiency Points:

    • Point A: Resources are not fully utilized.

    • Point B: All resources are used (maximum efficiency).

    • Point C: Cannot be achieved with current resources.

  • Example: If a company has 200 cars:

    • At point A: 100 cars utilized (inefficient).

    • At point B: 200 cars utilized (efficient).

    • Point C: Unattainable.

Opportunity Cost

  • Opportunity Cost: What is foregone to pursue an action, such as producing one more car or item.

    • Example: To gain one additional train, a significant amount of rice must be sacrificed.

Economic Growth and Production Possibilities

  • Economic growth can be achieved through:

    1. Increased resources.

    2. Improved technology.

    3. Innovations such as AI, steam engines, railroad advancements.
