Introduction

• Presented by Jacob Clifford
• Covers concepts needed for quizzes, unit exams, or final exams
• Based on the AP curriculum, relevant for introductory microeconomics courses

Activity

• Purpose: Illustrates the progression from easy to hard concepts in economics

Key Concepts in Microeconomics Unit 1

1. Scarcity and Choices

   • Economics focuses on scarcity and the necessity of making choices
   • Unlimited wants vs. limited resources
   • Scarcity affects individuals, businesses, and governments

2. Economic Systems

   • Society’s economic system determines production, methods, and allocation
   • Types: Command economies, Free-market economies, Mixed economies

3. Production Possibilities Curve (PPC)

   • Shows different combinations of two goods using full resources
   • Demonstrates efficiency, opportunity costs, and resource allocation

4. Comparative Advantage and Trade

   • Countries specialize and trade based on lower opportunity costs
   • Allows for specialization and improved economic outcomes

5. Marginal Analysis

   • Involves weighing additional benefits and costs of decisions

Detailed Topics

Scarcity and Decision-Making

• Factors of production: Land, Labor, Capital, Entrepreneurship
• Difference between Microeconomics (individual and firm decisions) and Macroeconomics (economy-wide factors)

Economic Systems

• Command economy: Government-controlled production and distribution
• Free market: Driven by profit and competition
• Mixed economy: Combination of free market and government intervention

• Calculating opportunity costs and determining mutually beneficial trade terms
• Difference between output and input questions

Cost Concepts

• Explicit vs. Implicit costs
• Opportunity costs as a factor in decision-making

Marginal Analysis

• Making decisions based on marginal (additional) benefits and costs
• Law of Diminishing Marginal Utility
• Utility Maximization: Marginal Utility per Dollar

Practical Applications

• Use of graphs and calculations in problem-solving
• Emphasis on active participation and practice

Study Resources

• Study guide provided for detailed learning and practice
• Encouragement to use additional resources and videos for more complex topics

Conclusion

• Recommended activities for consolidation: Practice questions and review packet
• Importance of active learning and participation for success in economics
