Marginal Revenue and Rule of Thumb Pricing
Profit maximization requires that a firm produce where marginal revenue equals marginal costs. Firm managers are unlikely to have complete information concerning their marginal revenue function or their marginal costs.

- R' = C'
- R' =
(1 + 1/e ) - MC =
(1 + 1/e ) - MC =
+ /e - (
- C')/ = - 1/e
Markup is the difference between price and marginal cost. The formula states that markup as a percentage of price equals the negative of the inverse of elasticity of demand.Alternatively, the relationship can be expressed as:
= C'/(1 + 1/e )
Thus if e
