The law of demand states that as prices rise over a period of time, the quantity demanded wil fall.
This is made up of two effects: The Income effect and the Substitution effect.
The income effect states that as prices rise, the purchasing power/ real income of consumers fall.
The substitution effect states that as the price of one good rises, consumers switch to buying cheaper alternatives.
The price elasticity of demand is a measure of the responsiveness of quantity demanded to a change in price. This indicates, to a certain extent, whether consumer are dependant on that good or not. If the PED is inelastic, people are dependant on that good: they are relatively unresponsive to a change in price. e.g. Petrol. If demand is elastic, there are alternatives readily available in the market. e.g. Cars.
distinguish between price elasticity of demand and income elasticity of demand
Inelasticity is a good that you will buy nomatter the price change. Elasticity is when the price of a product increases demand for the product will decrease.
Along a linear demand curve elasticity varies from point to point of the demand curve with respect to different price, but slope is constant
1)price elasticity of demand 2)income elasticity of demand 3)cross elasticity of demand
Unitary elasticity is when the price elasticity of demand is exactly equal to one.

Inelasticity is a good that you will buy nomatter the price change. Elasticity is when the price of a product increases demand for the product will decrease.
price elasticity is the degree to which demand for a good will change relative to a change in the price of that good. Income elasticity is the degree to which demand for a good will change relative to a change in the spending power of the consumer. it is the percentage change in quantity demanded/percentage change in price.
The price elasticity refers to the change in demand due to the change in price. The income elasticity of demand on the other hand refers to the change in demand due to the change in income.
Along a linear demand curve elasticity varies from point to point of the demand curve with respect to different price, but slope is constant
The price elasticity of demand should be negative. This is because the relationship between demand and price, according to the law of demand, is negative.
1)price elasticity of demand 2)income elasticity of demand 3)cross elasticity of demand
Unitary elasticity is when the price elasticity of demand is exactly equal to one.
Cross price elasticity of demand measures the responsivenss of demand for a product to a change in the price of another good.
In economics , the cross elasticity of demand and cross price elasticity of demand measures the responsiveness of the quantity demand of a good to a change in the price of another good.
Price elasticity is a specific type of slope of the demand curve. A perfectly inelastic demand means that the quantity will not change with the price. This line is perfectly vertical. A perfectly elastic demand curve is horizontal and means that at any given quantity, there is only one price. Also, a slope gets steeper, demand becomes more inelastic.
