For a seller in a purely competitive market, the need curve is totally elastic, and, therefore, horizontal in a price-quantity graph. A competitive seller deserve to sell as much as he desires at the industry price. However, the demand curve for all sellers in the industry is downward sloping where need quantity rises as price decrease. For a pure monopolist, its supply is the whole market supply, and, thus, downward sloping. Since a syndicate is a price maker, it will determine what quantity of output will certainly yield the best profits. Yet first, let united state see exactly how revenue is maximized. To simplify the adhering to discussion, we assume that the monopolist will only charge a single price for its product and that that is not topic to government regulation.

You are watching: To maximize profit, a pure monopolist must:

Maximizing Revenue

In trying come maximize revenue, the monopolist has actually a dilemma: the monopolist have the right to only sell much more product if it lowers its prices, due to the fact that it"s demand curve slopes bottom as need curves usually do. Need only rises with diminish prices, however the marginal revenue gained by offering one added unit will always be much less than the price of that unit due to the fact that the monopolist should sell all units at the reduced price.

Except for the an initial unit, marginal revenue is constantly less than price. Because that instance, expect a monopolist have the right to sell 1 widget for $100, but it can sell 2 widgets for $90. Producing 1 widget, the monopolist has complete revenue that $100; creating 2 widgets, and also selling them because that $90 apiece yields total revenue that $180. Therefore, the monopolist"s marginal revenue is $80 (= $180 – $100), i m sorry is $10 much less than the price important to offer 2 widgets. If it deserve to only sell 3 widgets because that $75, then its total revenue is $225, therefore its marginal revenue is just $45 (= $225 – $180). Together the quantity produced increases, marginal revenue continually declines until it becomes zero, then negative.

Note that this is in comparison to the compete market, wherein the vain firm have the right to sell all the it wants for the sector price. Therefore, the marginal revenue = marginal price = industry price. Together the monopolist increases production, marginal revenue continually decreases until it in reality becomes negative. In ~ this point, the monopolist is earning the maximum complete revenue. Much more production ~ that point will cause total revenue come decline.


Total revenue can likewise be examined using demand elasticity. The monopolist will rise production as lengthy as need is inelastic, since increased amounts yields increased revenue. When demand becomes elastic, then enhancing the quantity much more decreases full revenue, so the monopolist will set its price where demand reaches unit elasticity, right before it becomes elastic. Or, if the market need remains inelastic, then the monopolist will develop what the industry demands.

For instance, a manufacturer that produces a effective lifesaving cancer drug will naturally create as lot of the medicine as there room cancer victims that would benefit from the drug. To develop less, would minimize profits, because the manufacturer could easily charge a price that exceeds its ATC for the drug, due to the fact that demand will certainly not readjust much with the price (inelastic demand). On the various other hand, to produce more of the drug 보다 there space cancer victims would cause the price that the medicine to fall, causing less revenue overall. Because the drug manufacturer has a patent for the drug, it has a monopoly. It additionally has a well-defined industry of a particular size. Thus, it have the right to maximize its own profits by charging the highest possible price the the victims and their insurance companies are willing or able to pay, learning that the cancer victims will certainly do every little thing they can to pay the price. This is why several drug manufacturers considerably increased your prices recently, come take benefit of inelastic demand for their products.

Price Determination

like the competitive firm, the monopolist will collection its price when:

Marginal Revenue (MR) = Marginal expense (MC)

Because as long as marginal revenue above marginal cost, climate producing an additional unit will rise profits. As soon as marginal revenue equals marginal cost, climate the monopolist looks to the demand curve to view what price that synchronizes to. At the point, profit is maximized. If the monopolist boosts production beyond MR = MC, climate the marginal expense will be greater for each extr unit than marginal revenue, which will decrease profits, due to the fact that costs continue to increase.

ATC = Average complete Cost mr = Marginal Revenue MC = Marginal expense

1 Productive Efficiency: MC = Minimum ATC

2 Allocative Efficiency: MC = sector Price

Monopoly Profit = (Price - ATC) × Quantity

Note that a monopoly does not have a supply curve because it sets the it is provided according to the demand. In most markets, the market price is determined by the intersection of the need curve and also supply curve. However, for a monopoly, the industry price is not set by the intersection of the demand and also supply curves, because that the monopolist decides what the supply will certainly be — the monopolist sets the price at which its profits are maximized, which will certainly then identify what the supply will be.

To summarize, the monopolist find the profit maximizing output by detect that amount where marginal revenue = marginal cost, then projects that quantity on come the market need curve to recognize what sector price synchronizes to that quantity. The monopolist"s economic profit is then same to the average revenue minus the ATC (ATC) multiplied by the variety of units sold:

Monopoly Profit = (Price - ATC) × Quantity
= (Average Revenue × Quantity) - (ATC × Quantity) = total Revenue - total Cost

This analysis refutes 2 usual misconceptions about syndicate pricing: the the monopolist fees the highest possible price feasible and the it looks for a maximum every unit profit. Obviously, the above analysis demonstrates the monopolies perform not charge the greatest prices due to the fact that it doesn"t yield the maximum profit. After ~ all, the greatest price can be charged only if the monopolist created 1 unit that output. Obviously, it could never cover its fixed costs by developing only 1 unit that output, for this reason it will not charge the greatest price possible.


Since profit maximization is the goal, profits can always be boosted as long as marginal revenue exceeds marginal cost. Hence, the monopolist has no attention in maximizing every unit profit, because this does not yield the greatest profit.

exactly how a Monopolist Minimizes Losses

It is feasible that a monopolist have the right to actually lose money if ATC over the price that civilization are ready to pay for any quantity the output. Losses deserve to be resulted in by a change in consumer tastes or by transforms in the price of inputs. However, if the monopolist cannot do a profit, climate it will shutdown the firm therefore it deserve to put the sources to better uses. A monopolist will certainly only develop in the short run to minimize losses if the perceives the market problems will change or that it will have the ability to earn a profit in the future.

In this case, the monopolist will still develop the quantity where marginal revenue amounts to marginal cost because that quantity synchronizes to the sector price that will minimize its losses. Its losses will certainly then be equal to:

Monopoly ns = (ATC – Price) × Quantity
