For a seller in a purely competitive industry, the demand also curve is completely elastic, and also, therefore, horizontal in a price-amount graph. A competitive seller have the right to market as a lot as he desires at the industry price. However, the demand also curve for all sellers in the market is downward sloping wright here demand amount increases as prices decrease. For a pure monopolist, its supply is the whole industry supply, and, therefore, downward sloping. Because a syndicate is a price maker, it will certainly identify what amount of output will certainly yield the biggest profits. But initially, let us watch just how revenue is maximized. To simplify the following discussion, we assume that the monopolist will just charge a solitary price for its product and also that it is not topic to government regulation.

You are watching: For a pure monopolist, marginal revenue is less than price because:

Maximizing Revenue

In trying to maximize revenue, the monopolist has actually a dilemma: the monopolist can just market more product if it lowers its prices, because it"s demand also curve slopes downward as demand curves primarily perform. Demand only rises with decreasing prices, yet the marginal revenue acquired by marketing one additional unit will certainly always be much less than the price of that unit because the monopolist must market all systems at the lower price.

Except for the initially unit, marginal revenue is always much less than price. For circumstances, intend a monopolist can sell 1 widacquire for $100, however it have the right to sell 2 widgets for $90. Producing 1 widacquire, the monopolist has actually full revenue of $100; producing 2 widgets, and marketing them for $90 aitem yields complete revenue of $180. Thus, the monopolist"s marginal revenue is $80 (= $180 – $100), which is $10 less than the price important to market 2 widgets. If it have the right to just market 3 widgets for $75, then its full revenue is $225, so its marginal revenue is only $45 (= $225 – $180). As the amount developed rises, marginal revenue continually declines until it becomes zero, then negative.

Keep in mind that this is in contrast to the competitive market, wbelow the competitive firm deserve to market all that it desires for the market price. Because of this, its marginal revenue = marginal price = sector price. As the monopolist rises production, marginal revenue continually declines till it actually becomes negative. At this allude, the monopolist is earning the maximum total revenue. More manufacturing after that suggest will cause complete revenue to decline.


Total revenue can additionally be examined making use of demand also elasticity. The monopolist will boost production as long as demand also is inelastic, bereason raised amounts returns boosted revenue. When demand becomes elastic, then enhancing the amount more decreases full revenue, so the monopolist will collection its price wbelow demand also reaches unit elasticity, right prior to it becomes elastic. Or, if the market demand also stays inelastic, then the monopolist will produce what the industry demands.

For circumstances, a manufacturer that produces a successful lifesaving cancer drug will normally create as a lot of the drug as tright here are cancer victims that would certainly benefit from the drug. To produce less, would certainly alleviate revenues, given that the manufacturer might easily charge a price that exceeds its ATC for the drug, because demand also will certainly not readjust a lot through the price (inelastic demand). On the various other hand, to produce more of the drug than tbelow are cancer victims would certainly reason the price of the drug to autumn, resulting in less revenue as a whole. Since the drug manufacturer has actually a patent for the drug, it has a syndicate. It also has actually a well-identified sector of a details dimension. Therefore, it have the right to maximize its own profits by charging the highest price that the victims and their insurance suppliers are willing or able to pay, understanding that the cancer victims will certainly execute whatever they can to pay the price. This is why numerous drug manufacturers significantly enhanced their prices freshly, to take benefit of inelastic demand for their commodities.

Price Determination

Like the competitive firm, the monopolist will certainly collection its price when:

Marginal Revenue (MR) = Marginal Cost (MC)

Since as lengthy as marginal revenue exceeds marginal price, then producing a second unit will certainly increase revenues. When marginal revenue amounts to marginal price, then the monopolist looks to the demand curve to watch what price that synchronizes to. At that suggest, profit is maximized. If the monopolist rises manufacturing past MR = MC, then the marginal expense will be greater for each extra unit than marginal revenue, which will decrease revenues, because expenses continue to boost.

ATC = Average Total Cost MR = Marginal Revenue MC = Marginal Cost

1 Productive Efficiency: MC = Minimum ATC

2 Allocative Efficiency: MC = Market Price

Monopoly Profit = (Price - ATC) × Quantity

Keep in mind that a monopoly does not have actually a supply curve because it sets the supply according to the demand. In many markets, the sector price is identified by the intersection of the demand also curve and supply curve. However, for a syndicate, the industry price is not set by the interarea of the demand also and also supply curves, for the monopolist decides what the supply will be — the monopolist sets the price at which its earnings are maximized, which will certainly then recognize what the supply will be.

To summarize, the monopolist finds the profit maximizing output by finding that amount wbelow marginal revenue = marginal cost, then projects that amount on to the sector demand curve to recognize what sector price corresponds to that amount. The monopolist"s financial profit is then equal to the average revenue minus the ATC (ATC) multiplied by the number of devices sold:

Monopoly Profit = (Price - ATC) × Quantity
= (Mean Revenue × Quantity) - (ATC × Quantity) = Total Revenue - Total Cost

This evaluation refutes 2 prevalent misconceptions around monopoly pricing: that the monopolist charges the highest possible price feasible and also that it seeks a maximum per unit profit. Obviously, the over evaluation demonstprices that monopolies carry out not charge the highest prices because it does not yield the maximum profit. After all, the greatest price can be charged just if the monopolist produced 1 unit of output. Obviously, it could never cover its addressed costs by developing only 1 unit of output, so it will not charge the greatest price possible.


Due to the fact that profit maximization is the goal, revenues have the right to constantly be raised as long as marginal revenue exceeds marginal cost. Hence, the monopolist has actually no interemainder in maximizing per unit profit, given that this does not yield the greatest profit.

How a Monopolist Minimizes Losses

It is feasible that a monopolist have the right to actually shed money if ATC exceeds the price that people are willing to pay for any type of quantity of output. Losses deserve to be caused by a readjust in customer tastes or by alters in the price of inputs. However before, if the monopolist cannot make a profit, then it will certainly shutdvery own the firm so it deserve to put the sources to much better uses. A monopolist will certainly just produce in the short run to minimize losses if it perceives that market conditions will change or that it will have the ability to earn a profit in the future.

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

Monopoly Loss = (ATC – Price) × Quantity
