Study Notes

Scarcity

  • Scarcity occurs when unlimited wants exceed limited resources, central to the study of economics.
  • Food, time, gas, and workers are not considered scarce resources by economists.

Production Possibilities Frontier (PPF)

  • The PPF illustrates the maximum attainable combinations of two goods that can be produced with available resources.
  • Economic efficiency is represented by points on the PPF, while inefficiency is shown by points inside the frontier.
  • Technological advances can cause the PPF to shift outward, indicating increased production capacity.

Comparative Advantage

  • Comparative advantage refers to the ability of an individual, firm, or country to produce a good or service at a lower opportunity cost than competitors.

Circular Flow Diagram

  • The circular flow diagram represents how households and firms interact through product and factor markets.
  • Participants in markets are categorized as firms and households, with households playing a crucial role in determining production of goods and services.

Capital and Factors of Production

  • Capital consists of goods used to produce other goods.
  • Inputs used to create goods and services are termed factors of production.

Opportunity Cost

  • Scarcity implies that every choice comes with an opportunity cost, representing the highest valued alternative forgone.

Rational Decision-Making

  • Economic models assume individuals act rationally, aiming to maximize benefits while minimizing costs.
  • Optimal decisions occur when marginal benefits equal marginal costs.

Economic Questions

  • Societies must address three fundamental economic questions:
    • What goods will be produced?
    • How will these goods be produced?
    • For whom will these goods be produced?

Economic Systems

  • Centrally planned economies allocate resources through governmental decisions, often lacking incentives for hard work and innovation, leading to inefficiencies.
  • Market economies answer essential economic questions through the decisions of households and firms, promoting competition and efficiency.

Efficiency and Equity

  • Productive efficiency is achieved when goods/services are produced at the lowest possible cost.
  • Allocative efficiency occurs when the production of goods/services meets the point where marginal cost equals marginal benefit.
  • Overall efficiency maximizes societal benefits, whereas equity ensures fairness in the distribution of goods.

Trade-offs and Choices

  • Trade-offs compel societies to make choices when addressing the three key economic questions.
  • In a market system, firms decide how goods and services will be produced, influencing resource allocation and efficiency in production.
