The Law of Demand and the "All Else Equal Assumption"

Economist use the latin term "ceteris Paritous" meaning all else equal, to indicate that they are looking only at a specified relationship, such as the one between price and quantity demanded.

Consumers respond to a change in price with a relatively large change in the quantity demanded.

Elastic Demand

A measure of how strongly consumers respond to a change in the price of a good, calculated as the percentage change in the quantity demanded divided by the percentage change in the price.

Elasticity Of Demand

A measure of the responsiveness of the quantity supplied to price changes, calculated by dividing the percentage change in the quantity demanded divided by the percentage change in price.
