What is the Law of Demand?
An inverse relationship between price and quantity demanded. Quantity demanded falls when prices rise and it rises when prices fall.
What is market demand?
The sum of all the individual quantities demanded by each buyer in the market at each price.
What does a price change cause in regards to the demand curve?
A price change causes movement ALONG a given demand curve, but it cannot cause a shift in the demand curve.
What variables can shift demand?
- Taste and preferences.
- Changes in buyer’s income
- Price of related goods
- Expectations regarding the future price
- Number of buyers

- Consumers buy more of a normal good when their income rises.

- Subsidies

What is the Law of Supply and Demand?
The amount at which the quantity supplied is equal to the quantity demanded.
