Study Notes

Introduction to Microeconomics

  • Scarcity is the fundamental economic problem: limited resources to meet unlimited wants.
  • Economics is the study of how individuals and societies make decisions given scarcity.
  • Economists analyze how people interact and how resources are allocated.
  • Efficiency maximizes benefits from scarce resources.
  • Equality distributes benefits evenly among society.
  • Opportunity cost represents the value of the best alternative forgone when making a choice.
  • Rational people make informed decisions to maximize their objectives.
  • Incentives motivate behavior and are crucial for understanding market dynamics.
  • Trade benefits everyone involved, allowing for specialization, efficiency, lower prices, and access to more goods and services.
  • Market economy relies on decentralized decision-making by firms and households.
  • Property rights guarantee individuals' control over their resources, crucial for markets to function.
  • Market failure occurs when markets inefficiently allocate resources.
  • Externalities are unintended consequences affecting bystanders.
  • Market power allows a single actor to significantly influence market prices.

Supply and Demand Basics

  • Supply and demand determine the prices and quantities of goods and services.
  • The Law of Demand states that as prices increase, the quantity demanded decreases (inverse relationship).
  • Demand represents the quantity consumers are willing and able to buy at various prices.
  • Factors affecting demand:
    • Consumer Preferences: Tastes and preferences influence demand.
    • Income: Consumer income affects demand for normal and inferior goods.
    • Prices of Related Goods: Substitutes and complements impact demand.
    • Expectations: Anticipations about future prices and income influence current demand.
    • Population: Changes in population affect overall demand.
    • Economic Conditions: Recessions impact demand negatively.
  • The Law of Supply states that as prices increase, the quantity supplied increases (direct relationship).
  • Supply represents the quantity producers are willing and able to sell at various prices.
  • Factors affecting supply:
    • Production Costs: Input costs (e.g., labor, materials) affect supply.
    • Technology: Technological improvements can increase supply.
    • Number of Producers: More suppliers increase overall market supply.
    • Government Policies: Taxes, subsidies, and regulations influence supply.
    • Expectations: Producer expectations of future prices affect current supply.
    • Natural Conditions: Weather and other environmental factors impact agricultural and natural resource-based supply.

Market Equilibrium and Efficiency

  • Market equilibrium occurs when the quantity demanded equals the quantity supplied at a given price.
  • Equilibrium Price (Pâ‚‘): The price where quantity demanded and supplied balance.
  • Equilibrium Quantity (Qâ‚‘): The quantity bought and sold at the equilibrium price.
  • Surplus: Exists when the price is above the equilibrium price, creating an excess supply.
  • Shortage: Exists when the price is below the equilibrium price, creating an excess demand.

Elasticity: Price, Income, and Cross Elasticity

  • Elasticity measures the responsiveness of quantity demanded or supplied to changes in price, income, or the prices of related goods.
  • Types of Elasticity:
    • Price Elasticity of Demand (PED): Measures the sensitivity of quantity demanded to price changes.
    • Income Elasticity of Demand (YED): Measures the sensitivity of quantity demanded to income changes.
    • Cross Elasticity of Demand (XED): Measures the sensitivity of demand for one good to price changes of another good.
  • Income Elasticity of Demand (YED):
    • Normal Goods (YED > 0): Demand increases as income rises.
    • Necessities (0 < YED < 1): Demand increases with income, but at a slower rate.
    • Luxuries (YED > 1): Demand increases proportionally more than income increases.
    • Inferior Goods (YED < 0): Demand decreases as income rises.
  • Cross Elasticity of Demand (XED):
    • Substitute Goods (XED > 0): Products that can be used in place of each other.
    • Complementary Goods (XED < 0): Products used together.
    • Unrelated Goods (XED = 0): No significant relationship.

Consumer Behavior and Utility Maximization

  • Consumer behavior focuses on how individuals make decisions about selecting, purchasing, and using goods and services.
  • Rationality: Consumers strive to maximize their satisfaction (utility) given their income.
  • Utility: Represents the level of satisfaction or pleasure derived from consuming goods and services.
  • Preferences: Consumers have different ranked preferences for goods and services.
  • Types of Utility:
    • Total Utility (TU): Overall satisfaction from consuming a certain quantity.
    • Marginal Utility (MU): Additional satisfaction from consuming one more unit.
    • Average Utility: Total utility divided by the number of units consumed.
    • Cardinal Utility: Assumes utility can be measured numerically.
    • Ordinal Utility: Assumes utility can only be ranked, not measured precisely.

Production and Cost

  • Production involves transforming inputs into outputs.
  • Law of Diminishing Returns: As more units of a variable input (e.g., labor) are combined with fixed inputs (e.g., land), the additional output (marginal product) eventually decreases.
  • Factors of Production:
    • Land: Natural resources used in production (renewable and non-renewable).
    • Labor: Human effort used in production.
    • Capital: Tools, equipment, machinery, and buildings used in production.
    • Entrepreneurship: Ability to organize the other factors of production to create goods and services.
  • Short Run: A period where at least one input is fixed (e.g., capital), while others can be varied.
  • Fixed Inputs: Factors that cannot be easily changed in the short run.
  • Variable Inputs: Factors that can be adjusted in the short run.
  • Fixed Costs (FC): Costs that do not vary with output.
  • Variable Costs (VC): Costs that vary with output.
