# Relationship between demand and marginal revenue monopoly utilities At the profit-maximizing level of output marginal revenue equals marginal cost, We seek to show that at the monopoly output the price-elasticity of demand is 1 or more. ..

Conventionally, price is the vertical axis and output the horizontal one. Marginal Revenue Marginal revenue is the marginal addition to revenue added by the next unit of output sold. As a function, it is the derivative of the total revenue curve, which is found by inverting the demand function and then multiplying that by quantity. Marginal revenue curves, which are described by marginal revenue functions, usually have the same intercept as demand but half the slope.

They are graphed using the same axes as the demand curve. Marginal Revenue and Demand Because marginal revenue is partially based on the inverted demand curve, if something changes demand, marginal revenue will also change. A shift in demand would be reflected graphically as the demand curve shifting downward and inward: Marginal revenue shares the same intercept as demand, so it moves down by the same amount.

A shift in the demand curve by a given amount will shift the marginal revenue curve by the same amount and in the same direction.

How Demand Changes Many factors can influence the demand curve. A rival product might appear with a cheaper price, for instance, which would attract customers and reduce demand for the original. Consequently, the monopolist's marginal revenue will also be falling as the monopolist increases its output. If it is assumed that the monopolist cannot price discriminate, that is, charge a different price for each unit of output it produces, then the monopolist's marginal revenue from each additional unit produced will not equal the price that the monopolist charges.

In fact, the marginal revenue that the monopolist receives from producing an additional unit of output will always be less than the price that the monopolist can charge for the additional unit. To understand why, consider a monopolist that is currently supplying N units of output. Suppose the monopolist decides to supply 1 more unit.

This new lower price reduces the total revenue that the monopolist receives from the first N units sold. At the same time, the monopolist will gain some revenue from the additional unit it supplies.

• Price and Output under Monopoly
• Relationship between Average and Marginal Revenue Curves
• Demand in a Monopolistic Market

The marginal revenue that the monopolist receives from supplying 1 additional unit is equal to the price that it receives for this unit minus its loss in revenue from having to sell N units of output at a lower market price.

The relationship between marginal revenue and price in a monopolistic market is best understood by considering a numerical example, such as the one provided in Table.

Profit Maximization

As the price falls, the market's demand for output increases, in keeping with the law of demand.
