Study Notes
Economic Concepts
- Scarcity: A situation where unlimited wants exceed limited resources.
- Resources: Includes natural resources (land, water, minerals), labor, capital, and entrepreneurial ability used to produce goods and services.
- Trade-off: Producing more of one good necessitates producing less of another due to scarcity.
Economic Models
- Economic Models: Simplified representations of reality for analyzing real-world economic situations.
- Economic Variables: Measurable elements relating to resources, with varying values (e.g., wages, prices, liters of petrol).
-
Model Development Steps:
- Decide on assumptions.
- Formulate testable hypotheses.
- Utilize economic data for testing.
- Revise models based on failure to explain data.
- Retain revised models for future inquiries.
Analysis Types
- Positive Analysis: Focuses on objective, verifiable statements about what is.
- Normative Analysis: Involves subjective value judgments about what ought to be, which cannot be tested.
Microeconomics vs. Macroeconomics
- Microeconomics: Examines choices made by households and firms, their market interactions, and government influence.
- Macroeconomics: Studies the economy as a whole, covering inflation, unemployment, and economic growth.
Economic Growth
- Economic Growth: Represents the expansion of society's production potential, often illustrated with the Production Possibility Frontier (PPF).
Comparative Advantage and Trade
- Production Possibility Frontier (PPF): Used to explain economic gains from specialization and trade.
- Trade: Involves the buying and selling of goods/services within a market.
- Absolute Advantage: The ability to produce more of a good using the same resources compared to competitors.
- Comparative Advantage: The ability to produce a good at a lower opportunity cost than other producers.
- Basis for Trade: Driven by comparative advantage, not absolute advantage; specialization and trade enhance welfare.
