Study Notes

Demand Concepts

Demand refers to the willingness and ability of consumers to purchase a good or service.
According to the law of demand, when prices decrease, the quantity demanded increases, while an increase in prices results in a decrease in quantity demanded.

Demand Schedules

A demand schedule illustrates the quantity of a good that an individual is willing to buy at various price points.
A market demand schedule aggregates the willingness to purchase of all consumers at each price level.

Demand Representation

A demand curve visually represents the data from a demand schedule, plotting price against quantity demanded.
A market demand curve serves the same function for a market demand schedule, aggregating data for all consumers.

Consumer Behavior Principles

The law of diminishing marginal utility indicates that the additional satisfaction from consuming each extra unit of a product diminishes over time.
The income effect describes how changes in purchasing power influence the quantity of goods consumers buy.
The substitution effect occurs when consumers opt for substitute goods in response to price changes, affecting demand.

Changes in Demand

A change in quantity demanded is a shift in the amount purchased resulting from price changes.
A change in demand occurs due to factors that prompt consumers to buy different amounts at every price level, influenced by elements beyond just price.

Goods Classification

Normal goods see increased demand when consumer incomes rise, while inferior goods experience decreased demand under the same circumstances.
Substitutes are goods that can replace each other, affecting demand dynamics.
Complements are goods used together, where an increase in demand for one boosts demand for the other.

Demand Elasticity

Elasticity of demand measures consumer responsiveness to price changes, categorized as:
- Elastic: demand significantly changes with price fluctuations.
- Inelastic: demand changes little despite price adjustments.
- Unit elastic: percentage change in price matches percentage change in quantity demanded.

Revenue Concepts

Total revenue is the income generated by a company from sales.
The total revenue test is a method for evaluating demand elasticity by analyzing changes in total revenue in response to price alterations.
