Strand 1: Introduction to Economics

Nature and Scope of Economics

Branches and Different Approaches in Economics
  • Microeconomics: Focus on individual units (households/firms).
  • Macroeconomics: Study of overall economy (national income, unemployment, growth).
  • Normative vs. Positive Economics:
    • Normative: Value judgments on what ought to be done.
    • Positive: Descriptive statements based on facts.
Key Terms:
  1. Economic Variables: Measurements for economy function (population, unemployment).
  2. Generalization: Broad statements applicable to groups.
  3. Microeconomics: Behavior of individuals and firms.
  4. Macroeconomics: Economy’s total performance.
  5. Rational Choice: Decisions based on logical reasoning.
  6. Scarcity: Limited resources against unlimited wants.
Multiple Choice & Questions:
  • Focus on distinguishing Micro vs. Macroeconomics, and identifying Normative vs. Positive statements.

Scope and Methodologies in Economics

Achievement Indicators:
  • Understanding economic methodology (Inductive vs Deductive).
Fallacies:
  1. Fallacy of Composition: What’s true for one may not be true for all.
  2. Post Hoc Fallacy: Erroneous conclusions about causation.
  3. Wishful Thinking: Ignoring contradicting evidence.
  4. Generalizations: Misleading conclusions from limited samples.
Important Concepts:
  1. Economic Law: Statements about tendencies under certain conditions.
  2. Economic Model: Simplified reality representation.
  3. Economic Theory: Explains cause-efficence relationships from facts.
  4. Economic Policy: Government actions to influence economy.

Schools of Economic Thought

  1. Classical: Invisible hand, rational behavior, free market (Adam Smith).
  2. Neo-Classical: Marginal utility, supply-demand relations (Alfred Marshall).
  3. Keynesian: Demand-driven analysis, state intervention (John Maynard Keynes).
  4. Monetarist: Money supply focus, limited government role (Milton Friedman).
  5. Welfare: Maximizing economic welfare and efficiency.

Strand 2: Microeconomics

Consumer Behavior

Utility Definitions:
  • Total Utility (TU): Overall satisfaction from consumption.
  • Marginal Utility (MU): Additional satisfaction from consuming extra unit.
Laws:
  1. Law of Diminishing Marginal Utility: As consumption increases, additional satisfaction decreases.
  2. Optimal Purchase Rule: Consume until price equals marginal utility (P=MU).
Indifference Curves:
  • Definition: Shows combinations of goods yielding equal satisfaction.
  • Shape: Convex due to diminishing marginal utility.
Budget Line:
  • Graphical representation of combinations of goods based on income and prices.
Consumer Equilibrium:
  • Achieved when marginal utility per dollar spent on each good is equal.

Strand 3: Macroeconomics

Money Supply

Primary Factors Affecting Money Supply:
  • Government transactions, foreign aid, remittances impact overall money availability.
Secondary Factors:
  • Credit creation process, reserve ratios influencing lending capacity.
    \n- Multiplier Effect: Increase in spending results in greater overall income; typically calculated through the formula (1 / (1 - MPC)).
Interest Rates:
  • Interest rates inversely affect investment and savings. Low rates encourage spending, high rates discourage it (Paradox of Thrift).

Conclusion: Issues of Equitable Income Distribution

Lorenz Curve Analysis

  • Illustrates inequality in income distribution. Further away from the line of equality indicates higher inequality.

Redistribution via Government Policies

  • Utilize taxation, welfare, and subsidies to balance income inequality.

  • Discuss the Economic Concepts:

  1. Externalities (positive and negative).
  2. Exchange rates and market dynamics affecting the economy.
  3. Supply and Demand interactions in labor markets.
  • Strategies for Sustainable Economic Growth in Fiji: Implement policies and frameworks to maintain economic stability while addressing environmental sustainability.
