Study Notes

Economics Overview

  • Economics studies how individuals and societies allocate limited resources to satisfy unlimited wants.
  • Scarcity refers to the limited resources and unlimited wants of a society.
  • Microeconomics focuses on individuals, businesses, and industries.
  • Macroeconomics studies the overall aspects and workings of an economy.

Five Foundations of Economics

  • Incentives: People respond to incentives.
    • Positive incentives motivate action, such as getting paid for work.
    • Negative incentives discourage action, such as jail time for theft.
    • Direct incentives are explicit rewards or punishments for specific actions.
    • Indirect incentives reflect secondary consequences of actions.
  • Trade-offs: Every choice involves a trade-off of alternative opportunities.
  • Opportunity Cost: The highest-valued alternative sacrificed when making a choice.
  • Marginal Thinking: Evaluating the benefit of one more unit of something against the cost of that unit.
    • Marginal benefit is the additional benefit gained by consuming an extra unit.
    • Marginal cost is the additional cost incurred by consuming an extra unit.
  • Trade Creates Value: Voluntary exchanges of goods and services create value for both parties involved. Specialization in roles promotes trade and increases overall output.

Markets

  • Markets enable buyers and sellers to exchange goods and services.
  • Markets facilitate specialization and trade.
  • Examples of markets: farmers market, Craigslist, stock exchange.

Economic Models

  • Models simplify complex situations.
  • Models are built on assumptions to make predictions.
  • Economists use models to understand the economy.
    • Example model: supply and demand.
  • Model building must carefully consider what variables to include and exclude.
  • Important assumptions: "Ceteris Paribus," meaning "all other things held equal."

Endogenous vs. Exogenous Factors

  • Endogenous factors are variables within a model and determined by the model itself.
  • Exogenous factors are variables outside a given model and affect the model, such as income.

Positive vs. Normative Economics

  • Positive economics deals with factual statements about the economy, testable through observation.
  • Normative economics involves opinions and value judgments about the economy.
