Study Notes
Introduction to Economics
- Economics studies how agents make choices with limited resources and how those choices impact society.
- The core concept is choice, not wealth, uniting all economic study.
- Economic agents are any entity (consumers, firms, governments) that makes choices, usually attempting optimal outcomes.
- Scarce resources are goods or services not sufficient to meet everyone's needs.
Branches of Economics
- Positive economics describes actual economic agent behavior—objective, factual analyses of how the economy functions. It predicts and explains without judgment.
- Examples: Average wages in different sectors, gender income gaps and their determinants.
- Normative economics dictates what economic agents should do—subjective judgments leading to public policy recommendations—examples: best job offers based on preferences and qualifications, policies to close income gaps.
Microeconomics vs. Macroeconomics
- Microeconomics studies individual agents' choices—their interactions affect resource allocation, prices, and the well-being of other agents.
- Examples: Consumer choices, electricity market designs, firm competitive strategies.
- Macroeconomics examines the economy as a whole—aggregate production, inflation, economic cycles, labor market, and monetary policy.
- Examples: Impact of labor reforms on unemployment and GDP, effectiveness of government economic stimulus programs.
Principles of Economics
- Optimization: Making the best choice possible based on available information.
- Possible/feasible: Options accessible to the agent
- Given Information: Could be incomplete
- Best: Depends on the agent's preferences.
- Trade-offs: Sacrificing one thing to gain another.
- Budget constraint: Limitation on choices due to limited resources.
- Opportunity cost: Value of the best alternative choice.
- Cost-benefit analysis: Comparing costs and benefits using a common measure.
- Equilibrium: No individual agent benefits from changing their behavior.
- Examples: Grocery store lines, housing markets, political party competition.
- Free-rider problem: Benefits without paying full costs (example: shared house cleaning/lighthouse example)
- Empiricism: Using data to answer economic questions.
- Correlation vs. causation.
- Examples: Beach crowding and temperatures; cause and effect (Omitted variables, reverse causality)
Studying Economics
- Scientific Method: A process used to test models.
- (1) Model building—simplified representation of reality.
- (2) Hypothesis generation—predictions from the model.
- (3) Testing the model with data.
- (4) Refine if the model does not completely reflect reality.
- Models: Simplified representations of reality—helpful to understand complex systems (e.g., metro map).
- Data Analysis: Causation vs. correlation (important to consider omitted variables and reverse causality).
- Good Economic Questions: Relevant, important, addressable via data.
- Graphics/Equations: Tools for summarizing information (linear relationships y = mx + n).
- Optimization (levels): Total benefit minus total cost.
- Optimization (differences): Marginal analysis—calculating changes in net benefit. Limits to optimization: incomplete information.
Markets
- Market: A place of trading goods/services governed by rules/arrangements.
- Market price: Price at which transactions occur.
- Perfectly competitive market: All participants are price takers.
