Study Notes
Consumer Theory
- Consumers make calculated decisions to maximize utility (satisfaction) when shopping.
- People are always looking to consume more and gain further satisfaction.
- Satisfaction from consumption decreases with every additional unit consumed (decreasing marginal utility).
Substitution Effect
- The substitution effect occurs when the price of a good changes and consumers adjust their consumption to maintain a balance between the marginal utility and the price of goods.
Income Effect
- The income effect is the change in purchasing power resulting from price changes and substitutions.
Giffen Goods
- Giffen goods are an exception to the law of demand, where consumption increases with an increase in price.
- This occurs due to a strong income effect that outweighs the substitution effect.
Demand
- Demand represents the desire for a good or service backed by purchasing power and willingness to buy.
- Demand is influenced by price, quantity demanded, and time.
Law of Demand
- The law of demand states that as the price of a good increases, the quantity demanded decreases, and vice versa.
Determinants of Demand
- Price: As price increases, demand decreases (and vice versa). Elasticity refers to how much demand is affected by price changes.
- Income: Higher income generally leads to increased demand, but the effect can vary depending on the good/service.
- Prices of related goods:
- Complementary goods: When the price of a complementary good increases, demand for the main good decreases (e.g., coffee and creamer).
- Substitute goods: When the price of a substitute good increases, demand for the main good increases (e.g., iPhone vs. Android phone).
- Tastes: Changes in preferences or desires for a product can affect demand.
- Expectations: Expectations about future price changes can influence current demand.
- Number of buyers: An increase in the number of buyers in the market leads to increased demand.
Elasticity of Demand
- The elasticity of demand measures the responsiveness of demand to changes in a variable like price.
Types of Demand Elasticities
- Price Elasticity of Demand: Measures the sensitivity of demand to price changes.
- Income Elasticity of Demand: Measures the sensitivity of demand to changes in consumer income.
- Cross Elasticity of Demand: Measures the sensitivity of demand for one good to changes in the price of another good.
- Substitute goods: Cross elasticity of demand is negative.
- Complementary goods: Cross elasticity of demand is positive.
- Promotional (Advertising) Elasticity of Demand: Measures the effect of advertising expenditure on sales.
Consumption Decisions
- Consumption decisions are influenced by factors like budget constraints, total utility, and timeframes.
Short-Run Consumption Decisions
- Short-run decisions are made when consumption is constrained by existing assets, commitments, and knowledge.
Long-Run Consumption Decisions
- Long-run decisions allow for adjustments in consumption patterns over a longer time horizon, taking into account potential changes.
Price Discrimination
- Price discrimination involves charging different customers different prices for the same product or service based on their perceived willingness to pay.
- First-degree price discrimination (perfect price discrimination): The seller charges each customer the maximum price they are willing to pay.
Types of Price Discrimination
- First-degree price discrimination: Charges the maximum price for each unit consumed, capturing all consumer surplus.
- Second-degree price discrimination: Charges different prices based on the quantity consumed (e.g., bulk discounts).
- Third-degree price discrimination: Divides customers into groups based on attributes (e.g., student discounts) and charges different prices to each group.
