Introduction
Hey there, readers! Welcome to our in-depth guide on marginal revenue for monopolies. In this article, we’ll delve into the complexities of this crucial concept and its implications for businesses and consumers alike.
So, what is marginal revenue? Simply put, it’s the additional revenue a monopoly earns by selling one more unit of output. But why is it so important? Well, understanding marginal revenue is essential for monopolies to maximize profits and make optimal pricing decisions.
Marginal Revenue and Demand
The Monopolist’s Demand Curve
Monopolies, unlike competitive firms, face a downward-sloping demand curve. This means that as they increase output, the price they can charge per unit decreases. This unique demand curve shapes their marginal revenue curve.
Marginal Revenue Curve
The marginal revenue curve for a monopolist lies below the demand curve. This is because the increase in total revenue from selling one more unit is less than the price received for that unit. The difference between the price and marginal revenue represents the opportunity cost of selling an additional unit.
Maximizing Profits
Marginal Revenue = Marginal Cost
To maximize profits, a monopolist must produce where marginal revenue equals marginal cost. This is because at this point, the additional revenue from selling one more unit just covers the additional cost of producing it. Producing more or less than this optimal quantity would result in lower profits.
Consumer Surplus and Deadweight Loss
Monopolists’ profit-maximizing production levels inevitably lead to market inefficiencies. Consumers end up paying higher prices and receiving less quantity than they would in a competitive market. This results in a reduction in consumer surplus and the creation of deadweight loss, a social welfare loss.
Measuring Elasticity and Marginal Revenue
Price Elasticity of Demand
The price elasticity of demand measures the responsiveness of quantity demanded to changes in price. A monopolist’s price elasticity of demand is an important factor in determining marginal revenue. The less elastic the demand, the lower the marginal revenue at any given price.
Marginal Revenue as a Function of Elasticity
The marginal revenue curve is closely related to the price elasticity of demand. If demand is elastic, meaning quantity demanded is highly responsive to changes in price, the marginal revenue curve will be steeper. Conversely, if demand is inelastic, the marginal revenue curve will be flatter.
Table: Marginal Revenue and Price Elasticity
| Price Elasticity of Demand | Marginal Revenue |
|---|---|
| Elastic ( | > 1 |
| Unit Elastic | = 1 |
| Inelastic | < 1 |
Conclusion
Marginal revenue for a monopoly is a complex but critical concept. Understanding it allows monopolies to maximize profits and for policymakers to assess the potential welfare costs associated with monopolies.

FAQ about Marginal Revenue for a Monopoly
What is marginal revenue (MR) for a monopoly?
The change in total revenue resulting from selling one additional unit of output.
How is MR different for a monopoly compared to a competitive firm?
For a competitive firm, MR equals the market price. For a monopoly, MR is lower than the price because the monopoly must reduce the price of all units sold to sell an additional unit.
What is the relationship between MR and total revenue?
For a monopoly, MR is positive when the demand curve is downward sloping. When MR is greater than zero, total revenue is increasing. When MR is less than zero, total revenue is decreasing.
How does a monopoly set its output level?
A monopoly will set its output level where MR equals marginal cost (MC). At this point, the monopoly is maximizing its profit.
How does a monopoly’s MR curve relate to its demand curve?
The MR curve is twice as steep as the demand curve. This is because the monopoly must lower the price of all units sold to sell an additional unit.
What is the profit-maximizing price for a monopoly?
The profit-maximizing price is the price at which the monopoly’s MR curve intersects its MC curve.
How does a monopoly’s profit differ from that of a competitive firm?
A monopoly can earn supernormal profits in the long run, while a competitive firm cannot.
Can a monopoly ever have a negative MR?
Yes, if the demand curve is highly elastic.
Why is MR important for a monopoly?
MR is a key factor in determining the monopoly’s output level, price, and profit.
How can a government regulate a monopoly to prevent price gouging?
The government can regulate a monopoly by setting a price ceiling or by imposing a tax on the monopoly’s profits.
