marginal revenue

Economics

The increase in total revenue when the quantity sold increases by a small amount, measured per unit of the increase in sales. If the seller is a price-taker, marginal revenue is equal to price. Where the seller faces a downward-sloping demand curve, where p is price and y is quantity sold, and the elasticity of demand is defined as ε‎_d = − (p/y)(dy/dp), marginal revenue is

$M R = \frac{d R}{d y} = y \frac{d p}{d y} + p = p [1 - \frac{1}{ε_{d}}] .$

Positive marginal revenue thus requires that ε‎_d > 1.
