The Economic Problem

  • Definition: Fewer resources than unlimited wants.
  • Types of Goods:
    • Economic Goods: Have opportunity costs.
    • Free Goods: Do not have opportunity costs (e.g., sunlight).

Factors of Production

  • Remember with the acronym CELL:
    • Capital: Manufactured resources.
    • Enterprise: Skills and willingness to take risks.
    • Land: Natural resources.
    • Labor: Human resources.
  • Rewards for Factors:
    • Land: Rent
    • Labor: Wages
    • Capital: Interest
    • Enterprise: Profits

Mobility of Factors

  • Geographical Mobility: Willingness to relocate for employment.
    • Barriers: Family ties, commitments, cost of living.
  • Occupational Mobility: Changing jobs affected by training period and education.

Opportunity Cost

  • Definition: Cost of the next best alternative when choosing a good.
  • Production Possibility Curve (PPC):
    • Points inside the curve are inefficient.
    • Points outside the curve are unattainable.
    • Outward Shift: New resources, technology, increased labor force.
    • Inward Shift: Natural disasters, low investments, resource depletion.

Branches of Economics

  • Microeconomics: Study of particular markets.
  • Macroeconomics: Study of the whole economy.

Key Economic Questions

  1. What to produce?
  2. How to produce?
  3. For whom to produce?

Price Mechanism

  • Decisions based on the equilibrium point of supply and demand.

Demand

  • Definition: Willingness and ability to buy goods/services at a given price.
  • Law of Demand: Higher prices lead to lower demand.
  • Factors Affecting Demand:
    • Price, advertising, government policies, consumer tastes, income, substitutes, interest rates.
  • Types of Demand:
    • Individual Demand: Demand by one individual.
    • Market Demand: Aggregate of all individual demands.

Supply

  • Definition: Ability and willingness to provide goods/services at a given price.
  • Law of Supply: Higher prices lead to higher quantity supplied.
  • Factors Affecting Supply:
    • Costs of production, prices of other goods, global factors, technology advances, business optimism.
  • Types of Supply:
    • Individual Supply: Supply by one producer.
    • Market Supply: Aggregate supply from all firms.

Market Equilibrium

  • Equal supply and demand in an economy.

Price Elasticity of Demand (PED)

  • Definition: Responsiveness of demand to price changes.
  • Types: Inelastic and elastic demand.
  • Factors Affecting PED: Number of substitutes, time period, income proportion, necessity.

Price Elasticity of Supply (PES)

  • Definition: Responsiveness of quantity supplied to price changes.
  • Formula: % change in quantity supplied / % change in price.
  • Factors Affecting PES: Time, resource availability, spare capacity, substitution.

Economic Systems

  • Market Economic System: Run by private firms and individuals.
  • Market Failure: Price mechanism fails to allocate resources.
  • Mixed Economic System: Government involvement in the economy.

Functions and Characteristics of Money

  • Functions: Medium of exchange, unit of account, store of value, standard for deferred payment.
  • Characteristics: Acceptability, durability, portability, divisibility, scarcity.

Types of Banks

  • Commercial Banks: Provide financial services to the public.
  • Central Banks: Manage the currency and monetary policy.

Households and Factors Influencing Occupation

  • Influences: Challenge level, danger level, training length, education.
  • Demand for Labor: Affected by productivity.
  • Supply of Labor: Affected by training quality.

Wage Differentials

  • Occupational Wage Differentials: Job satisfaction, fringe benefits, labor immobility.
  • Wage Differentials in Same Job: Local pay agreements, discrimination, non-monetary agreements.

Specialization

  • Definition: Production broken down into tasks.

Trade Unions

    • Contractionary: Raises interest rates to reduce inflation.
    • Expansionary: Lowers interest rates to increase employment.
  3. Supply-Side Policies:

  • Recession: Opposite of economic growth.

Types of Employment

  • Cyclical, structural, frictional, seasonal unemployment.

Inflation and Deflation

  • Inflation: Sustained increase in price levels.
  • Deflation: Decrease in price levels (inflation falls below 0%).
  • Types of inflation: Cost-push, demand-pull.

Economic Development

  • Living Standards: Measure of economic well-being.
  • Poverty: Absolute (below income threshold) vs. Relative (below average income).
  • Causes of Poverty: Unemployment, low wages, illness, poor healthcare, low literacy, high population growth, poor infrastructure.

Population Factors
