Study Notes
Demand and Its Determinants
- Demand refers to the quantity of a good or service that consumers are willing and able to purchase at a given price level, during a certain period of time.
- Determinants of demand include:
- Price of the good or service
- Income of the consumer
- Prices of related goods
- Consumer preferences
- Population and demographic changes
The Law of Demand
- The Law of Demand states that, ceteris paribus (all other things being equal), as the price of a good or service increases, the quantity demanded decreases, and vice versa.
- This means that there is an inverse relationship between the price of a good and the quantity demanded.
Movement along the Demand Curve vs Shift of the Demand Curve
- Movement along the demand curve occurs when there is a change in the quantity demanded in response to a change in the price of the good or service, while keeping other factors constant.
- Shift of the demand curve occurs when there is a change in the demand for a good or service due to a change in one of the determinants of demand, such as a change in consumer preferences or income.
Elasticity of Demand
- Elasticity of demand measures the responsiveness of the quantity demanded of a good or service to changes in its price or other influential factors.
- It is calculated as the percentage change in quantity demanded in response to a percentage change in price.
- Elastic demand means that a small change in price will lead to a large change in quantity demanded, while inelastic demand means that a large change in price will lead to a small change in quantity demanded.
