Chapter 2.1 – The Basic Economic Problems: Scarcity, Choice, and Opportunity Cost

This chapter introduces the core economic problem: scarcity (unlimited wants, limited resources). You’ll learn how scarcity forces people to make choices and how every choice has an opportunity cost—the value of the next best alternative given up. The Production Possibilities Frontier (PPF) is introduced as a tool to visualize these concepts.

Chapter 2.2 – Central Problems of Economies

Learn the three fundamental questions every society must answer due to scarcity:

• What to produce? (The problem of resource allocation)
• How to produce it? (The problem of technique, e.g., labor-intensive vs. capital-intensive)
• For Whom to produce it? (The problem of distribution)

Chapter 2.3 – Economic Systems

Explore the different ways societies are organized to answer the three central questions. This chapter compares the main economic systems:

• Traditional Economy: Decisions are based on customs and beliefs.
• Capitalist (Market) Economy: Based on private ownership of resources and driven by profit.
• Command (Socialist) Economy: Based on collective (state) ownership and central planning.
• Mixed Economy: A system that combines elements of both market and command economies, featuring both private and public sectors.
