A Pure Monopoly Will Find That Marginal Revenue is Less Than Price: A Comprehensive Guide
Greetings, Readers!
Welcome to our in-depth exploration of pure monopolies and their relationship with marginal revenue. In this article, we’ll delve into the fascinating world of market structures and understand why a pure monopoly, a market where a single seller controls the entire supply, faces a unique situation where marginal revenue (MR) is less than price (P).
Understanding Pure Monopolies
A pure monopoly exists when a single firm has complete control over a particular market. This means that they are the sole supplier of a product or service, and consumers have no other options to choose from. Pure monopolies can arise due to various factors, such as:
Government-Granted Monopolies:
Certain industries, such as public utilities and infrastructure, are often deemed essential by governments. To prevent competition and ensure the reliable provision of these services, the government may grant monopoly status to specific companies.
Natural Monopolies:
In some industries, economies of scale are so significant that it is inefficient for multiple firms to operate. In such cases, a single firm can produce the entire market demand at a lower cost than multiple firms.
Technological Monopolies:
With the rapid advancement of technology, firms that develop unique products or processes may gain a temporary monopoly. Patents and intellectual property rights can provide exclusive rights to these firms, shielding them from competition.
Marginal Revenue and Price in Pure Monopolies
A pure monopoly faces a unique market situation where it has control over price and output. Unlike firms in perfect competition, monopolies do not take P as given. Instead, they can influence P by adjusting the quantity they supply. This unique position has significant implications for their marginal revenue:
MR < P: Why?
In a pure monopoly, the MR is less than P because of the downward-sloping demand curve. As the monopoly increases output, it must lower the P to attract more consumers. This means that the increase in revenue from selling an additional unit (MR) is always less than the P of that unit.
Graphical Representation:
Imagine a downward-sloping demand curve. MR can be represented as the slope of a tangent line to the demand curve. Since the demand curve is downward-sloping, the slope of the tangent line (MR) is less than the slope of the vertical line from the origin (P).
Implications for Pure Monopolies:
The fact that MR < P has several implications for pure monopolies:
Profit Maximization:
Monopolies maximize profits by producing at the point where MR = MC. However, due to MR < P, they will produce less than the quantity that would maximize total revenue.
Welfare Loss:
The gap between P and MR represents the welfare loss to consumers. Consumers pay a higher P than they would in a competitive market, but they receive less output.
Inefficient Production:
Monopolies tend to produce less output compared to firms in perfect competition. This can lead to a misallocation of resources and reduced overall economic efficiency.
Price Discrimination:
Monopolies may engage in price discrimination, where they charge different prices to different groups of consumers. This allows them to capture more of the consumer surplus and increase their profits.
Table Breakdown
| Concept | Description |
|---|---|
| Pure Monopoly | Market structure with a single supplier |
| Marginal Revenue (MR) | Change in revenue from selling an additional unit |
| Price (P) | Price at which the product is sold |
| Demand Curve | Graph showing the relationship between P and quantity demanded |
| Downward-Sloping Demand | Demand curve slopes downward as P increases |
| Profit Maximization | Producing at the point where MR = MC |
| Welfare Loss | Loss to consumers due to P > MR |
| Inefficient Production | Less output produced compared to perfect competition |
| Price Discrimination | Charging different prices to different groups |
Conclusion
Pure monopolies present a unique economic phenomenon where MR is less than P. This is due to the downward-sloping demand curve that they face. The MR < P relationship has significant implications for pure monopolies, including profit maximization, welfare loss, inefficient production, and price discrimination.

FAQ about "A Pure Monopoly will Find that Marginal Revenue"
1. What is marginal revenue?
- Marginal revenue is the additional revenue earned when one additional unit of a product is sold.
2. Why is marginal revenue lower than price for a monopolist?
- Because the monopolist must lower the price of all units, not just the last one sold, to sell an additional unit.
3. What is the relationship between marginal revenue and elasticity of demand?
- The elasticity of demand measures the responsiveness of quantity demanded to changes in price. If demand is elastic, marginal revenue will be positive. If demand is inelastic, marginal revenue will be negative.
4. Why does a monopolist set MR=MC?
- To maximize profit, a monopolist will set marginal revenue equal to marginal cost. This is because the marginal revenue of the last unit sold is the additional revenue earned from selling that unit, while the marginal cost is the additional cost incurred from producing that unit.
5. What happens if a monopolist sets MR>MC?
- If a monopolist sets MR>MC, it will earn supernormal profits. This is because it is charging a price that exceeds the marginal cost of production.
6. What happens if a monopolist sets MR<MC?
- If a monopolist sets MR<MC, it will incur losses. This is because it is charging a price that is below the marginal cost of production.
7. Is it possible for a monopolist to break even?
- Yes, a monopolist can break even if it sets MR=AC, where AC is average cost. This is because the average cost of production is the total cost of production divided by the number of units produced.
8. Can a monopolist make a profit in the long run?
- Yes, a monopolist can make a profit in the long run if it has some form of barrier to entry. This could include a legal monopoly, a technological advantage, or control over a key resource.
9. What are the implications of a monopoly for consumers?
- Monopolies can have several negative implications for consumers, including higher prices, reduced output, and lower quality.
10. Why are monopolies considered inefficient?
- Monopolies are considered inefficient because they produce less output than a competitive market and charge higher prices. This results in a loss of consumer and producer surplus.
