Revenue concepts ¢ Revenue (or turnover) is the income generated from the sale of output in product markets. ¢ There are two main revenue concepts to grasp at this stage: ¢ tutor 2 u™ l Average Revenue (AR) = Price per unit = total revenue / output l Marginal Revenue (MR) = the change in revenue from selling one extra unit of output Total revenue (TR) = price per unit x output

Importance of revenues tutor 2 u™ ¢ Revenues affect the profitability of a business ¢ When demand is price inelastic, a fall in price causes a fall in TR (marginal revenue will be negative) ¢ The elasticity of demand (AR) has an effect on the profit margins of businesses in competitive and concentrated markets ¢ When demand is perfectly elastic, then the AR and the MR curves are the same
