What is Economics?

• Definition: Economics is the social science that studies the production, distribution, and consumption of goods and services.
• Key Insight: Economics arises from the human desire for more goods than available resources (scarcity).

Nature of the Economic Problem

• Economic Problem: Limited resources vs. unlimited human wants.
• Scarcity: Lack of sufficient resources to meet all human desires.
• Summary: The fundamental economic problem is the scarcity of resources to satisfy human wants.

Economic Goods vs. Free Goods

• Economic Goods: Scarce in supply, produced with economic costs (e.g., diamond watches, Ferraris).
• Free Goods: Unlimited in supply, no cost to consume (e.g., sunlight, air).

Needs vs. Wants

• Needs: Essential for survival (e.g., food, shelter).
• Wants: Desirable but not necessary (e.g., luxury items).

Factors of Production

1. Land

   • Natural resources in an economy.
   • Reward: Rent.
   • Mobility: Geographically immobile; occupationally mobile.

2. Labor

   • Human resources available for production.
   • Reward: Wages and salaries.
   • Mobility: Highly occupationally mobile; geographically mobile depending on factors like family ties.

3. Capital

   • Man-made resources used for production (e.g., machinery).
   • Reward: Interest.
   • Mobility: Geographically immobile; occupationally mobile based on use.

4. Enterprise

   • Ability to take risks and organize production.
   • Reward: Profit.
   • Mobility: Highly mobile; dependent on entrepreneurial skills.

Opportunity Cost

• Definition: Opportunity cost is the next best alternative sacrificed when making a choice.
• Example: Choosing to study instead of sleeping results in a trade-off of lost sleep (if choosing to study) or lost knowledge (if choosing to sleep).

Production Possibility Curve (PPC)

• Definition: A diagram showing the maximum combinations of two goods that can be produced with available resources.
• Points on PPC:
  • Outside the Curve: Unattainable (insufficient resources).
  • Inside the Curve: Inefficient use of resources.
  • On the Curve: Efficient use of resources.
• Shifts in PPC:
  • Outward Shift: Increases due to more resources or improved technology.
  • Inward Shift: Decreases due to disasters, resource depletion, or investment decline.

Linking Concepts

• Opportunity Cost and PPC: Governments and producers can calculate opportunity cost using the PPC to make informed decisions on resource allocation.

Conclusion

• Understanding the interconnectedness of economic concepts is crucial for mastering economics.
