    • What are resources?

    • What does efficient allocation mean?

    • What are human needs?

    • What is demand?

Goals of Economics

  • Understand economic concepts and decision making.

  • Analyze the efficient use of resources in production.

  • Explore different economic systems.

Definition of Economics

Key Concepts in Microeconomics

  1. Choice: Limited resources lead to enforced choices.

  3. Opportunity Cost: Value of the next best alternative given up in decision-making.

  4. Production Possibilities Frontier (PPF): Represents combinations of two goods produced with limited resources.
