Study Notes
Scarcity and Trade-offs
- Scarcity arises when unlimited wants exceed limited resources.
- Resources include natural (land, water, minerals), labor, capital, and entrepreneurial ability.
- Trade-off reflects that increasing the production of one good reduces the production of another due to scarcity.
Economic Models
- Economic models simplify reality to analyze real-world economic situations.
- Economic variables are measurable elements related to resources, such as wages and prices.
- Model development steps:
- Decide on assumptions
- Formulate a testable hypothesis
- Test the hypothesis with data
- Revise the model if necessary
- Use the revised model for future questions
Economic Analysis Types
- Positive analysis: Focuses on what is; value-free, fact-based statements that can be verified.
- Normative analysis: Concerned with what ought to be; involves untestable value judgments.
Microeconomics vs. Macroeconomics
- Microeconomics studies choices made by households and firms and their market interactions.
- Macroeconomics examines the economy as a whole, covering inflation, unemployment, and growth.
Economic Growth
- Economic growth signifies the expansion of a society's production potential.
- Illustrated through the Production Possibility Frontier (PPF).
Comparative Advantage and Trade
- Comparative advantage is crucial for gains from specialization and trade.
- Trade involves buying and selling goods or services within a market.
- Absolute advantage refers to the ability to produce more using the same resources than others, while comparative advantage focuses on producing with lower opportunity costs.
- Specialization in production according to comparative advantage leads to better trade outcomes.
Opportunity Cost
- Opportunity cost is defined as the next best alternative forgone when making a choice.
- Formula: Opportunity Cost = Implicit Cost + Explicit Cost.
- Explicit costs represent actual expenses incurred; implicit costs indicate implied or non-monetary costs.
Economic Graphs
- Label all graphs for clarity.
- The price is plotted on the Y-axis, while quantity is plotted on the X-axis.
- Efficiency is achieved at the optimum point where Marginal Benefit equals Marginal Cost (MB = MC).
