There are three categories of elasticity:-
- Elastic demand - higher prices decreases the demand for a good
and vice versa.
- Inelastic demand - higher prices will not cause any significant
changes to the demand for a good.
- Unitary elastic demand - demand changes proportionally equals
the changes in the price.
The relationship between these three categories with total
revenue are given below :-
- Elastic demand :- Goods with elastic demand have negative
relationship with the total revenue. That is, when the price of a
good increases, the demand decreases. This will cause the total
revenue to fall.
- Inelastic demand :- Goods with inelastic demand will have
positive or direct relationship with the total revenue. That is,
when the price of a good increases, the demand remains the same.
This will cause the total revenue to rise.
- Unitary elastic demand :- For a good with unitary elastic
demand, the total revenue has a constant relationship with the
price. That is, it remains the same when the price rises or
falls.
