In this video we explore the relationship between the coefficient of price elasticity of demand and the effect that price changes have on total revenues.

Price elasticity of demand and total revenue - Revision video

When the coefficient of PED < 1, then a rise in price will increase total revenue. For example, if PED = -0.3, this means demand is price inelastic

When the coefficient of PED > 1, then a price fall will increase total revenue. For example, if PED = -2.5, this means demand is price elastic

When the coefficient of PED = 1, then demand is unitary elastic. This means a price change will leave total revenue unchanged

When demand is price inelastic, consumers are less sensitive to the price being charged. They have a lot of consumer surplus which businesses can possibly extract into extra revenue – perhaps as a result of price discrimination.
