    Study Notes

    The Scientific Method in Economics

    • Economists utilize the scientific method to analyze real-world phenomena.
    • They develop theories and test them with data.
    • Assumptions simplify complex situations to better understand cause and effect.

    The Role of Assumptions

    • Economists make assumptions to simplify models and make them easier to comprehend.
    • An example is the simplified model of international trade with only two countries.

    Economic Models

    • Economic models are simplified representations used to analyze economic situations.
    • The Circular-Flow Diagram and Production Possibilities Frontier are two key models.

    Circular-Flow Diagram

    • Illustrates the flow of goods, services, and resources between households and firms.
    • Shows the interactions in two main markets: the market for goods and services, and the market for factors of production.

    Production Possibilities Frontier (PPF)

    • Shows the trade-offs between producing two goods.
    • Demonstrates opportunity costs, efficiency, and economic growth.

    Microeconomics vs Macroeconomics

    • Microeconomics focuses on individual markets and decision-makers like households and firms.
    • Macroeconomics focuses on broader economic factors such as inflation, unemployment, and national income.

    Positive vs Normative Analysis

    • Positive statements are objective and based on facts.
    • Normative statements are subjective and value-based.
    • Example:
      • Positive: Increasing the minimum wage will reduce employment.
      • Normative: The government should raise the minimum wage.

    Economists as Policy Advisers

    • Economists provide advice to policymakers based on positive analysis.
    • They offer recommendations on issues like minimum wage laws, taxation, and healthcare reforms.

    Why Economists Disagree

    • Differences arise from varying scientific judgments, models, and values.
    • For example, economists may disagree about the balance between fairness and efficiency.
