ACC 818 — Module 1: Economic Issues and Concepts

Foundations of microeconomics. Establishes the core problem economics addresses (scarcity), the analytical tool used to think about trade-offs (the production possibility boundary), and the broad systems through which societies allocate resources (market vs. centrally planned).

Learning Outcomes

  • Recognize the four main characteristics of market economies
  • Explain scarcity, choice, and opportunity cost
  • Illustrate the production possibilities boundary
  • Discuss the four key economic problems
  • Distinguish economic systems and the role of government in a mixed economy
  • Distinguish positive vs. normative advice

Topic 1: Scarcity, Choice, Opportunity Cost

  • Scarcity — limited resources vs. unlimited wants. The foundational economic problem.
  • Opportunity cost — value of the next best alternative given up when a choice is made. Applies at both societal and individual level.
  • Marginal analysis — decisions made by weighing marginal cost vs. marginal benefit of one more unit (e.g. one more video game vs. a case of Coke).

Topic 2: Production Possibility Boundary (PPB)

  • A curve showing combinations of goods/services an economy can produce efficiently with available resources.
  • Movement along the curve = trade-off (more of one means less of another).
  • The PPB shifts outward via technological progress or trade.
  • Comparative advantage — produce what you have the lower opportunity cost in, then trade. Both parties can consume outside their individual PPB.

Topic 3: Economic Systems

  • Free-market economy — consumers’ wants drive what producers create; the market self-organizes resource allocation.
  • Centrally planned — historical context: USSR, China, Eastern Europe pre-1990s. Most have transitioned to market mechanisms.
  • Modern economies are mixed: market dynamics with government intervention.
