Study Notes
Microeconomics
-
Definition: The branch of economics that studies individual units such as consumers, firms, and industries.
-
Key Concepts:
- Supply and Demand: Fundamental principles governing market transactions.
-
Elasticity: Measures responsiveness of quantity demanded or supplied to changes in price.
- Price Elasticity of Demand: % change in quantity demanded / % change in price.
- Factors Affecting Elasticity: Availability of substitutes, necessity vs luxury, proportion of income spent, time period.
-
Utility: Satisfaction or pleasure derived from consuming goods/services.
- Marginal Utility: Additional satisfaction from consuming one more unit.
-
Cost Structures:
- Fixed Costs: Costs that do not change with the level of output.
- Variable Costs: Costs that vary with the level of output.
-
Market Structures:
- Perfect Competition: Many firms, homogeneous products, free entry/exit.
- Monopolistic Competition: Many firms, differentiated products.
- Oligopoly: Few firms, interdependent pricing.
- Monopoly: Single firm dominates the market.
Demand
-
Definition: The quantity of a good or service that consumers are willing and able to purchase at various prices.
-
Law of Demand: As the price of a good decreases, the quantity demanded increases, and vice versa, ceteris paribus.
-
Demand Curve:
- Graphical representation of the relationship between price and quantity demanded.
- Typically downward sloping from left to right.
-
Shifts in Demand: Changes that cause the demand curve to move to the left or right.
-
Increase in Demand: Rightward shift, often due to factors like:
- Increased consumer income (for normal goods)
- Changes in consumer preferences
- Price change of related goods (substitutes and complements)
- Population growth
-
Decrease in Demand: Leftward shift, often due to:
- Decrease in consumer income (for normal goods)
- Changes in consumer preferences
- Price change of related goods
-
Increase in Demand: Rightward shift, often due to factors like:
-
Factors Affecting Demand:
- Price: Main determinant of quantity demanded.
- Income: Higher income generally increases demand for normal goods and decreases for inferior goods.
- Tastes and Preferences: Changes can significantly impact demand.
- Expectations: Future expectations of prices can influence current demand.
- Number of Buyers: More buyers in the market typically increases demand.
Microeconomics Overview
- Microeconomics examines individual economic units such as consumers, firms, and industries.
- Central to microeconomics is the interaction of supply and demand which drives market transactions.
Key Concepts
- Supply and Demand: Essential principles that dictate market dynamics.
- Elasticity: Reflects how quantity demanded or supplied changes in relation to price fluctuations.
- Price Elasticity of Demand: Calculated by the percentage change in quantity demanded divided by the percentage change in price.
-
Determinants of Elasticity:
- Availability of substitutes affects how easily consumers can switch products.
- The nature of the good (necessity vs luxury) influences consumer responsiveness.
- The proportion of income allocated to the good can modify elasticity.
- Time period allows consumers to adjust behavior according to price changes.
- Utility: Represents the satisfaction gained from consuming goods and services.
- Marginal Utility: The added satisfaction from consuming an additional unit of a product.
Cost Structures
- Fixed Costs: Remain constant regardless of output levels; do not vary with production volume.
- Variable Costs: Fluctuate based on output levels; increase or decrease with production changes.
Market Structures
- Perfect Competition: Characterized by numerous firms, uniform products, and no barriers to entry or exit.
- Monopolistic Competition: Consists of many firms, each offering differentiated products to attract consumers.
- Oligopoly: Features a few firms whose pricing strategies are interlinked.
- Monopoly: Dominated by a single firm that controls the market entirely.
Demand Overview
- Demand Definition: The amount of a good or service that consumers are willing to buy at various price points.
- Law of Demand: Indicates that price decreases typically lead to increased quantity demanded, and vice versa, assuming other factors remain constant.
- Demand Curve: Decreases from left to right, illustrating the inverse relationship between price and quantity demanded.
Shifts in Demand
-
Increase in Demand: Depicted as a rightward shift in the demand curve; influenced by:
- Rising consumer income for normal goods.
- Shifts in consumer preferences towards a product.
- Price changes of related goods (both substitutes and complements).
- Growth in population leading to a larger consumer base.
-
Decrease in Demand: Represented as a leftward shift; triggered by:
- Declining consumer income affecting normal goods.
- Alterations in consumer preferences away from a product.
- Price changes of related goods reducing demand.
Factors Affecting Demand
- Price: Directly impacts the quantity demanded; higher prices typically decrease demand.
- Income: Increased income tends to boost demand for normal goods while diminishing demand for inferior goods.
- Tastes and Preferences: Shifts can lead to substantial changes in demand levels.
- Expectations: Anticipated future price changes can sway current consumer buying decisions.
- Number of Buyers: An increase in consumers typically elevates overall demand for products in the market.
Microeconomics Overview
- Microeconomics examines individual consumers and firms, their decision-making processes, and interactions within markets.
- Supply and Demand is a core economic model explaining price determination based on market equilibrium.
-
Elasticity quantifies the responsiveness of quantity demanded or supplied in reaction to price fluctuations.
- Price Elasticity of Demand gauges sensitivity of quantity demanded in response to price changes.
- Income Elasticity of Demand measures the effect of income changes on quantity demanded.
- Marginal Utility represents the extra satisfaction gained from consuming an additional unit of a product or service.
Market Structures
- Perfect Competition: Characterized by numerous firms offering identical products with unrestricted entry and exit.
- Monopoly: A single firm dominates the market, has control over pricing, and faces significant barriers to entry.
- Oligopoly: A few firms influence market prices and output through interdependent strategies.
Demand Essentials
- Demand represents the amount of a good or service that consumers are prepared to buy at varying price points.
- Law of Demand establishes an inverse relationship; as prices drop, demand increases, and vice versa.
- The Demand Curve visually illustrates this relationship, typically displaying a downward slope.
Factors Influencing Demand
- Price of the Good: Directly affects the quantity demanded, aligning with the law of demand.
- Consumer Income: A rise in income usually boosts demand for normal goods while reducing demand for inferior goods.
- Consumer Preferences: Shifts in consumer tastes or preferences alter demand dynamics.
-
Prices of Related Goods:
- Substitutes: An increase in the price of one good may lead to a rise in demand for its substitute.
- Complements: An increase in the price of one good can lower the demand for its complementary good.
- Expectations: Anticipated future changes in prices or income can shape current purchasing decisions.
Shifts in Demand
- A Rightward Shift indicates an increase in demand, often driven by higher income or positive changes in consumer preferences.
- A Leftward Shift signifies a decrease in demand, potentially due to lower income or unfavorable shifts in tastes.
