    Scope of Economics

    Economics studies how choices are made with scarce resources and their societal effects.

    Economic agents

    Groups or individuals that make choices about resource allocation.

    Scarce resources

    Goods that are limited and cannot satisfy all wants.

    Positive economics

    Describes what economic agents actually do based on objective facts.

    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.
