Study Notes
Demand Fundamentals
- A decrease in price leads to a change in quantity demanded for a product.
- Demand curves are consistently downward sloping, indicating an inverse relationship between price and quantity demanded.
- The Law of Demand states that more of a product will be purchased at lower prices compared to higher prices.
Elasticity of Demand
- For elastic demand, total expenditures decrease when prices rise and increase when prices fall.
- Milk has been identified as inelastic when a price drop leads to falling total revenues.
- Demand elasticity measures the sensitivity of quantity demanded to price changes.
- Inelastic demand means that a price increase leads to a smaller decrease in quantity demanded.
Demand Shift Factors
- An increase in demand is represented by a rightward shift of the demand curve.
- Market demand curves can shift due to changes in the number of consumers.
- Changes in the price of a product can affect the demand for its complementary goods—typically, a price increase leads to lower demand for complementary products.
Marginal Utility and Demand
- Diminishing marginal utility explains why consumers may buy less of a product as they acquire more units.
- Demand is characterized by desire, ability, and willingness to purchase a product.
Consumer Behavior Concepts
- Substitution effect describes changes in quantity demanded due to relative price shifts.
- Complements are goods that complement the use of other products.
- Substitutes are alternatives that can replace a product.
Microeconomics Overview
- Microeconomics examines the behavior and decision-making of individual units such as consumers and firms.
- Individual demand curves differ from market demand curves, which reflect the total demand across all consumers.
Calculating Demand
- Total expenditures result from multiplying the product’s price by the quantity demanded.
- Unit elastic demand describes a proportional change in quantity demanded due to price changes.
- Elastic demand indicates a sizable change in quantity demanded in response to price changes.
Demand Curve Characteristics
- The demand curve visually represents the quantity demanded for various prices.
- Movements along the demand curve illustrate changes in quantity demanded due to price alterations.
Key Terms
- Income effect: Change in quantity demanded based on changes in consumers' real purchasing power.
- Marginal utility: Additional satisfaction gained from using one more unit of a product.
- Elasticity: Measurement of how demand changes in response to price variations.
