    Study Notes

    Microeconomics

    Definition

    • Microeconomics: The branch of economics that studies individual agents and markets, focusing on the behavior of consumers and firms.

    Key Concepts

    • Supply and Demand

      • Law of Demand: As price decreases, quantity demanded increases, and vice versa.
      • Law of Supply: As price increases, quantity supplied increases, and vice versa.
      • Equilibrium Price: The price at which quantity demanded equals quantity supplied.

    • Elasticity

      • Price Elasticity of Demand: Measures responsiveness of quantity demanded to price changes.
        • Elastic (> 1): Demand changes significantly with price changes.
        • Inelastic (< 1): Demand changes little with price changes.
      • Price Elasticity of Supply: Measures responsiveness of quantity supplied to price changes.

    • Consumer Behavior

      • Utility: Satisfaction derived from consuming goods and services.
        • Marginal Utility: Additional satisfaction from consuming one more unit.
      • Budget Constraints: The limit on consumption choices based on income and prices.

    • Production and Costs

      • Factors of Production: Resources used to produce goods (land, labor, capital, entrepreneurship).
      • Short-run vs. Long-run:
        • Short-run: At least one input is fixed.
        • Long-run: All inputs can be varied; firms can enter or exit the market.
      • Costs
        • Fixed Costs: Costs that do not change with output level.
        • Variable Costs: Costs that change with output level.
        • Total Costs: Fixed + Variable Costs; Average Cost = Total Cost / Quantity.

    • Market Structures

      • Perfect Competition: Many firms, identical products, easy entry/exit; price takers.
      • Monopolistic Competition: Many firms, differentiated products, some market power.
      • Oligopoly: Few firms, interdependent pricing; potential for collusion.
      • Monopoly: Single firm, unique product, high barriers to entry; price maker.

    • Market Failures

      • Externalities: Costs or benefits affecting third parties (e.g., pollution).
        • Positive Externality: Benefits to others (e.g., education).
        • Negative Externality: Costs to others (e.g., smoking).
      • Public Goods: Non-excludable and non-rivalrous goods (e.g., national defense).
      • Information Asymmetry: Situations where one party has more or better information than the other (e.g., used car markets).

    • Role of Government

      • Regulations: Set rules to correct market failures.
      • Taxes and Subsidies: Used to influence behavior and correct externalities.
      • Antitrust Laws: Regulations to prevent monopolistic practices and promote competition.

    Application

    • Use microeconomic principles to analyze real-world situations, such as market trends, consumer choices, and business strategies.
    • Employ elasticity and consumer behavior insights for pricing strategies and product development.

    Microeconomics

    • Microeconomics is the study of individual economic agents (consumers, firms) and markets.

    Supply and Demand

    • Law of Demand: As the price of a good decreases, the quantity demanded will increase, and vice versa.
    • Law of Supply: As the price of a good increases, the quantity supplied will increase, and vice versa.
    • Equilibrium Price: Where the quantity demanded and quantity supplied are equal.

    Elasticity

    • Price Elasticity of Demand: Measures how sensitive quantity demanded is to changes in price.
      • Elastic (> 1): Demand changes significantly with price changes.
      • Inelastic (< 1): Demand changes little with price changes.
    • Price Elasticity of Supply: Measures how sensitive quantity supplied is to changes in price.

    Consumer Behavior

    • Utility: The satisfaction a consumer derives from consuming goods and services.
    • Marginal Utility: The additional satisfaction gained from consuming one more unit of a good or service.
    • Budget Constraints: The limit on consumption choices due to income and prices.

    Production and Costs

    • Factors of Production: Inputs used to produce goods and services, including land, labor, capital, and entrepreneurship.
    • Short-Run vs. Long-Run:
      • Short-Run: At least one input is fixed in the short run (e.g., factory size).
      • Long-Run: All inputs can be varied in the long run (e.g., a firm can build a new factory).
    • Costs:
      • Fixed Costs: Costs that do not change with the level of output (e.g., rent).
      • Variable Costs: Costs that change with the level of output (e.g., raw materials).
      • Total Costs: Fixed Costs + Variable Costs.
      • Average Cost: Total Cost / Quantity Produced.

    Market Structures

    • Perfect Competition: Many firms, identical products, easy entry and exit, price takers.
    • Monopolistic Competition: Many firms, differentiated products, some market power.
    • Oligopoly: Few firms, interdependent pricing, potential for collusion.
    • Monopoly: Single firm, unique product, high barriers to entry, price maker.

    Market Failures

    • Externalities: Costs or benefits that affect third parties who are not directly involved in the production or consumption of a good.
      • Positive Externality: Benefits to others (e.g., education).
      • Negative Externality: Costs to others (e.g., pollution).
    • Public Goods: Goods that are non-excludable (no one can be prevented from consuming them) and non-rivalrous (one person's consumption does not prevent another person from also consuming the good) (e.g., national defense).
    • Information Asymmetry: Situations where one party has more or better information than the other (e.g., used car markets).

    Role of Government

    • Regulations: Rules set by the government to correct market failures.
    • Taxes and Subsidies: Used to influence behavior and correct externalities.
    • Antitrust Laws: Prevent monopolistic practices and promote competition.

    Application

    • Apply microeconomic principles to analyze real-world situations (e.g., market trends, consumer choices, and business strategies).
    • Use elasticity and consumer behavior insights for pricing strategies and product development.
