A key characteristic of a monopolist is that it's a profit maximizer. A monopolistic market has no competition, meaning the monopolist controls the price and quantity demanded. The level of output that maximizes a monopoly's profit is when the marginal cost equals the marginal revenue.

If the marginal revenue exceeds the marginal cost, then the firm can increase profit by producing one more unit of output. For example, at an output of 4 in Figure 3, marginal revenue is and marginal cost is , so producing this unit will clearly add to overall profits.
At an output of 5, marginal revenue is and marginal cost is , so producing this unit still means overall profits are unchanged. However, expanding output from 5 to 6 would involve a marginal revenue of and a marginal cost of , so that sixth unit would actually reduce profits.
Thus, the monopoly can tell from the marginal revenue and marginal cost that of the choices in the table, the profit-maximizing level of output is 5. The monopoly could seek out the profit-maximizing level of output by increasing quantity by a small amount, calculating marginal revenue and marginal cost, and then either increasing output as long as marginal revenue exceeds marginal cost or reducing output if marginal cost exceeds marginal revenue.
This process works without any need to calculate total revenue and total cost. This quantity is easy to identify graphically, where MR and MC intersect. If you find it counterintuitive that producing where marginal revenue equals marginal cost will maximize profits, working through the numbers will help. Step 1. Remember, we define marginal cost as the change in total cost from producing a small amount of additional output.
Step 2. As a result, the marginal cost of the second unit will be:. Step 3. Remember that, similarly, marginal revenue is the change in total revenue from selling a small amount of additional output.
Step 4. As a result, the marginal revenue of the second unit will be:. Table 3 below repeats the marginal cost and marginal revenue data from Table 2, and adds two more columns. Marginal profit is the profitability of each additional unit sold. We define it as marginal revenue minus marginal cost. Finally, total profit is the sum of marginal profits. As long as marginal profit is positive, producing more output will increase total profits. When marginal profit turns negative, producing more output will decrease total profits.
Total profit is maximized where marginal revenue equals marginal cost. In this example, maximum profit occurs at 5 units of output. Once the monopolist identifies the profit maximizing quantity of output, the next step is to determine the corresponding price. Graphically, start from the profit maximizing quantity in Figure 3, which is 5 units of output. Draw a vertical line up to the demand curve. Then read the price off the demand curve i. The marginal revenue curve for a monopolist always lies beneath the market demand curve.
To understand why, think about increasing the quantity along the demand curve by one unit, so that you take one step down the demand curve to a slightly higher quantity but a slightly lower price. A demand curve is not sequential: it is not that first we sell Q 1 at a higher price, and then we sell Q 2 at a lower price. Rather, a demand curve is conditional: if we charge the higher price, we would sell Q 1. If, instead, we charge a lower price on all the units that we sell , we would sell Q 2.
So when we think about increasing the quantity sold by one unit, marginal revenue is affected in two ways. First, we sell one additional unit at the new market price. Second, all the previous units, which could have been sold at the higher price, now sell for less. Because of the lower price on all units sold, the marginal revenue of selling a unit is less than the price of that unit—and the marginal revenue curve is below the demand curve. Tip : For a straight-line demand curve, the marginal revenue curve equals price at the lowest level of output.
Graphically, MR and demand have the same vertical axis. As output increases, marginal revenue decreases twice as fast as demand, so that the horizontal intercept of MR is halfway to the horizontal intercept of demand. You can see this in the Figure 4.
He meant that monopolies may bank their profits and slack off on trying to please their customers. The old joke was that you could have any color phone you wanted, as long as it was black. An explosion of innovation followed. Services like call waiting, caller ID, three-way calling, voice mail through the phone company, mobile phones, and wireless connections to the internet all became available.
Companies offered a wide range of payment plans, as well. It was no longer true that all phones were black. Instead, phones came in a wide variety of shapes and colors.
The end of the telephone monopoly brought lower prices, a greater quantity of services, and also a wave of innovation aimed at attracting and pleasing customers. In the opening case, we presented the East India Company and the Confederate States as a monopoly or near monopoly provider of a good.
Regarding the cotton industry, we also know Great Britain remained neutral during the Civil War, taking neither side during the conflict. Did the monopoly nature of these business have unintended and historical consequences? Might the American Revolution have been deterred, if the East India Company had sailed the tea-bearing ships back to England?
Of course, it is not possible to definitively answer these questions. We cannot roll back the clock and try a different scenario. We can, however, consider the monopoly nature of these businesses and the roles they played and hypothesize about what might have occurred under different circumstances.
Perhaps if there had been legal free tea trade, the colonists would have seen things differently. There was smuggled Dutch tea in the colonial market. If the colonists had been able to freely purchase Dutch tea, they would have paid lower prices and avoided the tax.
What about the cotton monopoly? With one in five jobs in Great Britain depending on Southern cotton and the Confederate States as nearly the sole provider of that cotton, why did Great Britain remain neutral during the Civil War? At the beginning of the war, Britain simply drew down massive stores of cotton. These stockpiles lasted until near the end of Why did Britain not recognize the Confederacy at that point? Two reasons: The Emancipation Proclamation and new sources of cotton.
Having outlawed slavery throughout the United Kingdom in , it was politically impossible for Great Britain, empty cotton warehouses or not, to recognize, diplomatically, the Confederate States. In addition, during the two years it took to draw down the stockpiles, Britain expanded cotton imports from India, Egypt, and Brazil. Monopoly sellers often see no threats to their superior marketplace position. In these examples did the power of the monopoly blind the decision makers to other possibilities?
As a result of their actions, this is how history unfolded. A monopolist is not a price taker, because when it decides what quantity to produce, it also determines the market price.
For a monopolist, total revenue is relatively low at low quantities of output, because it is not selling much. Total revenue is also relatively low at very high quantities of output, because a very high quantity will sell only at a low price.
Thus, total revenue for a monopolist will start low, rise, and then decline. The marginal revenue for a monopolist from selling additional units will decline. Each additional unit a monopolist sells will push down the overall market price, and as it sells more units, this lower price applies to increasingly more units.
If that price is above average cost, the monopolist earns positive profits. Monopolists are not productively efficient, because they do not produce at the minimum of the average cost curve. As a result, monopolists produce less, at a higher average cost, and charge a higher price than would a combination of firms in a perfectly competitive industry. Monopolists also may lack incentives for innovation, because they need not fear entry. How much output should the firm supply? Hint : Draw the graph.
If price falls below AVC, the firm will not be able to earn enough revenues even to cover its variable costs. In such a case, it will suffer a smaller loss if it shuts down and produces no output. If it shuts down, it only loses its fixed costs. Imagine a monopolist could charge a different price to every customer based on how much he or she were willing to pay.
How would this affect monopoly profits? However, there would be no consumer surplus since each buyer is paying exactly what they think the product is worth. Therefore, the monopolist would be earning the maximum possible profits. How is the demand curve perceived by a perfectly competitive firm different from the demand curve perceived by a monopolist?
How does the demand curve perceived by a monopolist compare with the market demand curve? How can a monopolist identify the profit-maximizing level of output if it knows its total revenue and total cost curves? How can a monopolist identify the profit-maximizing level of output if it knows its marginal revenue and marginal costs? When a monopolist identifies its profit-maximizing quantity of output, how does it decide what price to charge?
How does the quantity produced and price charged by a monopolist compare to that of a perfectly competitive firm? Imagine that you are managing a small firm and thinking about entering the market of a monopolist. Before you go ahead and challenge the monopolist, what possibility should you consider for how the monopolist might react? If a monopoly firm is earning profits, how much would you expect these profits to be diminished by entry in the long run? Draw the demand curve, marginal revenue, and marginal cost curves from Figure , and identify the quantity of output the monopoly wishes to supply and the price it will charge.
Draw the new demand curve. What happens to the marginal revenue as a result of the increase in demand? What happens to the marginal cost curve? Identify the new profit-maximizing quantity and price. Does the answer make sense to you? According to the graph, is there any consumer willing to pay more than the marginal cost of that new level of output?
If so, what does this mean? Aboukhadijeh, Feross. Accessed July 7, British Parliament. Dattel, E. Accessed July Grogan, David. Accessed March 12, Massachusetts Historical Society. Pelegrin, William. Skip to content Monopoly. Learning Objectives By the end of this section, you will be able to: Explain the perceived demand curve for a perfect competitor and a monopoly Analyze a demand curve for a monopoly and determine the output that maximizes profit and revenue Calculate marginal revenue and marginal cost Explain allocative efficiency as it pertains to the efficiency of a monopoly.
Demand Curves Perceived by a Perfectly Competitive Firm and by a Monopoly A perfectly competitive firm acts as a price taker, so we calculate total revenue taking the given market price and multiplying it by the quantity of output that the firm chooses.
The flat shape means that the firm can sell either a low quantity Ql or a high quantity Qh at exactly the same price P. Thus, if the monopolist chooses a high level of output Qh , it can charge only a relatively low price PI.
Conversely, if the monopolist chooses a low level of output Ql , it can then charge a higher price Ph. The challenge for the monopolist is to choose the combination of price and quantity that maximizes profits.
