Basic Economic Concepts

Scarcity and Opportunity Cost

• Scarcity: Unlimited wants vs. limited resources.
• Opportunity Cost: The most desirable alternative given up when making a choice.
• Trade-offs: All the things given up in decision-making.

Microeconomics vs. Macroeconomics

• Microeconomics: Study of small economic units (firms, individuals).
• Macroeconomics: Study of the economy as a whole (inflation, unemployment, GDP).

Key Economic Assumptions

1. All resources are scarce.
2. Everything has a cost (no free lunch).
3. Everyone responds to incentives and acts in self-interest.
4. Decisions are made by comparing additional benefits and costs.
5. Life and the economy can be explained with graphs.

Investment

• Economics Definition: When businesses purchase machines, tools, and capital for their business.
• Consumer Goods vs. Capital Goods:
  • Consumer Goods: Made for direct consumption (e.g., pizza).
  • Capital Goods: Used to produce other goods (e.g., blenders).
• Human Capital: Skills and knowledge acquired by workers.

Factors of Production

• Land, Labor, Capital, Entrepreneurship: The essential resources for production.

Economic Systems

Types of Economies

• Centrally Planned Economy: Government owns resources.
• Free Market Economy: Individuals decide production and distribution.
• Mixed Economy: Combination of free market and centrally planned.

The Invisible Hand

• Concept that self-interest in a free market results in societal benefits.

Production Possibilities Curve (PPC)

• PPC: Graph showing trade-offs, opportunity cost, and efficiency.
• Straight Line PPC: Constant opportunity cost.
• Bowed Out PPC: Increasing opportunity cost.
• Economic Growth: Achieved by increasing capital goods.

Specialization and Trade

Comparative and Absolute Advantage

• Absolute Advantage: Ability to produce more with the same resources.
• Comparative Advantage: Lower opportunity cost in production.
• Specialization: Countries should specialize and trade based on comparative advantage.

Calculating Comparative Advantage

• Per Unit Opportunity Cost: Used to determine who should specialize in what.
• Terms of Trade: Agreed conditions that benefit both countries.

Supply and Demand

Demand

• Law of Demand: Inverse relationship between price and quantity demanded.
• Demand Curve: Downward sloping; shifts occur due to factors other than price.

Supply

• Law of Supply: Direct relationship between price and quantity supplied.
• Supply Curve: Upward sloping; shifts due to non-price factors.

Equilibrium

• Point where supply equals demand.
• Disequilibrium: Results in surplus or shortage.

Shifts and Movements

• Shifts in supply and demand curves affect equilibrium.
• Double Shifts: One factor (price or quantity) will be indeterminate.

Government Intervention

• Price Ceiling: Maximum price, causes shortages.
• Price Floor: Minimum price, causes surpluses.
