Q&A) • Break (15 mins.) • Topic E Efficiency and Equity and the Role of Government (Max. 10 mins. Q&A) • Elective 1 • Q&A Session

  3. (A) Basic Economic Concepts Economics as a social science • Study of human behaviors • Based on the postulate of constrained maximization • Use examples to illustrate the scope of economic analysis • Methodology of scientific study NOT required

  4. (A) Basic Economic Concepts Scarcity Choice and opportunity cost (i) The source of economic problems : scarcity • Unlimited wants and limited resources • Meaning of scarcity • Relationship between scarcity and choice • Relationship between scarcity, competition and discrimination • Difference between scarcity and shortage

  15. (A) Basic Economic Concepts • Value  Positive analysis  normative policy suggestion • From the standpoint of maximising social gains, should the illegal practice of reproducing discs be firmly suppressed so that only the higher-priced original discs can be found on the market?
