Defining Monopolistic Competition

Monopolistic vain is a kind of imperfect competition such that countless producers sell products that are identified from one another.

You are watching: 1. conditions for monopolistic competition

Key Takeaways

Key PointsMonopolistic competition is various from a monopoly. A monopoly exists when a human being or reality is the exclusive providers of a great or service in a market.Markets that have monopolistic competition space inefficient for 2 reasons. First, in ~ its optimum calculation the for sure charges a price that exceeds marginal costs. The second source of inefficiency is the reality that these firms operate with excess capacity.Monopolistic vain markets have actually highly distinguished products; have countless firms offering the an excellent or service; firms can freely enter and also exits in the long-run; firms have the right to make decisions independently; there is some degree of industry power; and also buyers and also sellers have actually imperfect information.Key Termsmonopoly: A industry where one agency is the single supplier.Monopolistic competition: A kind of imperfect vain such the one or 2 producers sell products that are distinguished from one an additional as goods yet not perfect substitutes (such as from branding, quality, or location).

Monopolistic Competition

Monopolistic vain is a kind of imperfect competition such that many producers sell assets that are identified from one another as goods yet not perfect substitutes (such as from branding, quality, or location). In monopolistic competition, a certain takes the prices charged through its rivals as given and ignores the affect of its very own prices on the prices of other firms.

Unlike in perfect competition, firms that space monopolistically competitive preserve spare capacity. Models that monopolistic competition are regularly used to model industries. Textbook instances of markets with industry structures comparable to monopolistic competition incorporate restaurants, cereal, clothing, shoes, and also service markets in big cities.


Clothing: The garments industry is monopolistically competitive because firms have distinguished products and market power.

Monopolistic competition is different from a monopoly. A monopoly exists when a person or reality is the exclusive supplier of a great or organization in a market. The need is inelastic and the sector is inefficient.

Monopolistic vain markets:

have commodities that are extremely differentiated, an interpretation that over there is a perception that the items are various for reasons various other than price;have many firms providing the an excellent or service;firms can freely enter and also exits in the long-run;firms deserve to make decisions independently;there is some degree of market power, an interpretation producers have some manage over price; andbuyers and also sellers have actually imperfect information.

Sources of market Inefficiency

Markets that have monopolistic competition room inefficient for two reasons. The first source of incompetent is as result of the reality that at its optimum output, the firm charges a price the exceeds marginal costs. The monopolistic competitive firm maximizes earnings where marginal revenue equals marginal cost. A monopolistic compete firm’s demand curve is bottom sloping, which means it will charge a price the exceeds marginal costs. The market power own by a monopolistic competitive firm way that in ~ its profit maximizing level of production there will be a network loss the consumer and producer surplus.

The 2nd source of inefficiency is the truth that this firms run with overabundance capacity. The firm’s profit maximizing calculation is much less than the output connected with minimum average cost. All firms, regardless of the type of industry it operates in, will create to a allude where need or price equals average cost. In a perfect competitive market, this occurs where the perfect elastic need curve equals minimum average cost. In a monopolistic vain market, the need curve is downward sloping. In the long run, this leader to excess capacity.

Product Differentiation

Product differentiation is the procedure of distinguishing a product or business from rather to make it an ext attractive come a target market.

Learning Objectives

Define product differentiation

Key Takeaways

Key PointsDifferentiation occurs because buyers consciousness a difference in between products. Causes of differentiation encompass functional aspects of the product or service, how it is distributed and also marketed, and also who buys it.Differentiation affect performance primarily by reducing straight competition. Together the product becomes much more different, categorization becomes an ext difficult, and also the product draws fewer comparisons v its competition.There room three species of product differentiation: simple, horizontal, and also vertical.Key Termsproduct differentiation: perceived differences in between the product the one firm and also that of its rivals for this reason that some customers worth it more.

One the the defining traits that a monopolistically competitive sector is the there is a far-reaching amount of no price competition. This means that product differentiation is crucial for any monopolistically compete firm. Product differentiation is the procedure of differentiating a product or organization from rather to do it more attractive come a target market.

Kool-Aid: Kool-Aid is an separation, personal, instance brand that competes through Kraft’s other brand (Tang).

Although study in a niche market may result in transforming a product in order to boost differentiation, the alters themselves space not differentiation. Marketing or product differentiation is the process of describing the differences between products or services, or the resulting perform of differences; differentiation is not the procedure of developing the differences between the products. Product differentiation is excellent in stimulate to demonstrate the unique aspects of a firm’s product and also to create a feeling of value.

In economics, effective product differentiation is inconsistent with the problems of perfect competition, i beg your pardon require commodities of contending firms to it is in perfect substitutes.

Consumers execute not need to know everything about the product for differentiation to work. So lengthy as the consumer perceive the there is a distinction in the products, they do not have to know exactly how or why one product might be of higher quality 보다 another. For example, a share brand of cereal might be specifically the exact same as a brand name in regards to quality. However, consumers might be ready to pay an ext for the brand name in spite of the fact that lock cannot identify why the more expensive grain is of higher “quality.”

There room three species of product differentiation:

Simple: the assets are differentiated based upon a selection of characteristics;Horizontal: the commodities are differentiated based on a single characteristic, yet consumers room not clean on which product is of higher quality; andVertical: the products are differentiated based upon a solitary characteristic and consumers room clear on i m sorry product is of greater quality.

Differentiation occurs since buyers perceive a difference. Motorists of differentiation include functional elements of the product or service, just how it is distributed and marketed, and who buys it. The significant sources of product differentiation room as follows:

Differences in quality, which room usually add by distinctions in price;Differences in functional functions or design;Ignorance the buyers concerning the vital characteristics and qualities of items they room purchasing;Sales promotion activities of sellers, an especially advertising; andDifferences in access (e.g. Timing and also location).

The objective of differentiation is to construct a position that potential customers see as unique. Differentiation influence performance mainly by reducing direct competition. Together the product becomes much more different, categorization becomes more difficult, and the product draws fewer comparisons with its competition. A effective product differentiation strategy will relocate the product from contending on price to competing on non-price factors.

Demand Curve

The need curve in a monopolistic competitive sector slopes downward, which has actually several vital implications because that firms in this market.

Learning Objectives

Explain just how the form of the need curve influence the firms the exist in a market with monopolistic competition

Key Takeaways

Key PointsThe bottom slope the a monopolistically competitive need curve signifies that the this firm in this industry have market power.Market power permits firms to boost their prices without losing all of their customers.The bottom slope the the demand curve contributes to the incompetent of the market, bring about a lose in customer surplus, deadweight loss, and excess manufacturing capacity.Key Termsmarket power: The capability of a firm to profitably progressive the sector price of a good or company over marginal cost. A certain with complete market power have the right to raise price without losing any kind of customers come competitors.elastic: sensitive to transforms in price.

The demand curve the a monopolistic competitive industry slopes downward. This means that as price decreases, the quantity demanded because that that good increases. While this shows up to be reasonably straightforward, the shape of the demand curve has actually several crucial implications because that firms in a monopolistic vain market.

Monopolistic Competition: together you can see indigenous this chart, the demand curve (marked in red) slopes downward, signifying elastic demand.

Market Power

The demand curve because that an separation, personal, instance firm is bottom sloping in monopolistic competition, in contrast to perfect competition whereby the firm’s individual need curve is perfect elastic. This is because of the truth that firms have actually market power: they deserve to raise price without losing all of their customers. In this type of market, these firms have a limited ability to dictate the price that its products; a certain is a price setter no a price taker (at least to some degree). The source of the industry power is that there room comparatively fewer rivals than in a competitive market, for this reason businesses focus on product differentiation, or differences unrelated to price. By distinguishing its products, firms in a monopolistically competitive industry ensure that its commodities are imperfect substitutes for each other. Together a result, a company that works on that branding can increase its price without risking its customer base.

Inefficiency in the Market

Monopolistically competitive this firm maximize their profit as soon as they develop at a level whereby its marginal expenses equals the marginal revenues. Due to the fact that the individual firm’s need curve is downward sloping, reflecting industry power, the price this firms will certainly charge will certainly exceed their marginal costs. Because of how products are priced in this market, consumer surplus decreases listed below the pareto optimal levels you would discover in a perfect competitive market, at least in the quick run. Together a result, the market will experience deadweight loss. The suppliers in this market will likewise have excess manufacturing capacity.

Short run Outcome that Monopolistic Competition

Monopolistic vain markets deserve to lead to far-reaching profits in the short-run, yet are inefficient.

Learning Objectives

Examine the principle of the short run and also how it applies to that company in a monopolistic competition

Key Takeaways

Key PointsThe “short run” is the time period when one factor of manufacturing is resolved in regards to costs, when the other elements of manufacturing are variable.Like monopolies, the suppliers in monopolistic competitive industries are price makers and also will behave likewise in the short-run.Also prefer a monopoly, a monopolastic vain firm will maximize the profits as soon as its marginal revenues equates to its marginal costs.Key Termsshort-run: The theoretical time duration in i beg your pardon at the very least one variable of production is solved in amount and also others are variable in amount.

In regards to production and also supply, the “short run” is the time duration when one aspect of production is resolved in state of costs while the other aspects of manufacturing are variable. The most common example of this is the production of a an excellent that needs a factory. If demand spikes, in the brief run you will only have the ability to produce the amount of an excellent that the volume of the manufacturing facility allows. This is due to the fact that it takes a far-reaching amount the time to either develop or obtain a brand-new factory. If need for the good plummets friend can cut production in the factory, however will still have to pay the expenses of keeping the factory and the connected rent or debt linked with gaining the factory. You could sell the factory, however again that would certainly take a far-reaching amount the time. The “short run” is identified by exactly how long it would take to transform that “fixed” aspect of production.

In the quick run, a monopolistically competitive industry is inefficient. The does not achieve allocative nor productive efficiency. Also, due to the fact that a monopolistic competitive firm has actually powers end the industry that are comparable to a monopoly, its profit maximizing level of production will result in a net loss of consumer and also producer surplus, producing deadweight loss.

Setting a Price and also Determining Profit

Like monopolies, the companies in monopolistic competitive sectors are price makers and will behave similarly in the short-run. Additionally like a monopoly, a monopolistic competitive firm will certainly maximize its earnings by producing goods to the point where its marginal revenues amounts to its marginal costs. The profit maximizing price that the good will it is in determined based upon where the profit-maximizing amount amount drops on the typical revenue curve. The benefit the firm renders is the the quantity of the good produced multiply by the difference in between the price minus the average cost of producing the good..

Short run Equilibrium Under Monopolistic Competition: together you deserve to see native the chart, the for sure will produce the amount (Qs) where the marginal price (MC) curve intersects with the marginal revenue (MR) curve. The price is set based on wherein the Qs falls on the typical revenue (AR) curve. The benefit the firm renders in the quick term is stood for by the grey rectangle, or the quantity produced multiplied through the difference between the price and also the average cost of creating the good.

Since monopolistically competitive firms have market power, castle will produce less and also charge an ext than a firm would under perfect competition. This reasons deadweight loss because that society, but, indigenous the producer’s allude of view, is desirable because it enables them to earn a profit and also increase their producer surplus.

Because that the possibility of large profits in the short-run and reasonably low obstacles of entrance in comparison to perfect markets, industries with monopolistic compete are really attractive to future entrants.

Long run Outcome the Monopolistic Competition

In the long run, firms in monopolistic competitive markets are very inefficient and can just break even.

Learning Objectives

Explain the concept of the long run and also how it applies to a that company in monopolistic competition

Key Takeaways

Key PointsIn regards to production and also supply, the ” long-run ” is the time period when all elements of manufacturing are variable and also can because of this be readjusted to accomplish shifts in demand.Like monopolies, the service providers in monopolistic competitive markets are price makers and will behave likewise in the long-run.Like a monopoly, a monopolastic competitive firm will certainly maximize its revenues by developing goods to the suggest where the marginal revenues equals its marginal costs.In the long-run, the demand curve of a certain in a monopolistic competitive market will change so the it is tangent to the firm’s average total cost curve. Together a result, this will certainly make it difficult for the firm come make economic profit; it will certainly only have the ability to break even.Key Termslong-run: The theoretical time duration in i m sorry there are no fixed factors of production.

In regards to production and also supply, the “long-run” is the time duration when over there is no variable that is fixed and also all elements of production are variable and can thus be adjusted to accomplish shifts in demand. Provided a long sufficient time period, a firm deserve to take the adhering to actions in solution to shifts in demand:

Enter an industry;Exit one industry;Increase its volume to develop more; andDecrease its capacity to produce less.

In the long-run, a monopolistically competitive market is inefficient. The achieves neither allocative nor abundant efficiency. Also, since a monopolistic compete firm has power over the market that is similar to a monopoly, its profit maximizing level of manufacturing will an outcome in a network loss the consumer and also producer surplus.

Setting a Price and also Determining Profit

Like monopolies, the suppliers in monopolistic competitive sectors are price makers and will behave similarly in the long-run. Additionally like a monopoly, a monopolistic compete firm will maximize its profits by creating goods come the point where the marginal revenues equals its marginal costs. The benefit maximizing price of the an excellent will be determined based on where the profit-maximizing quantity amount falls on the median revenue curve.

While a monopolistic competitive firm deserve to make a profit in the short-run, the effect of its monopoly-like pricing will reason a decrease in demand in the long-run. This increases the need for firms to identify their products, leading to rise in average full cost. The decrease in demand and also increase in cost reasons the lengthy run average cost curve to become tangent to the need curve in ~ the good’s profit maximizing price. This method two things. First, the the firms in a monopolistic competitive sector will create a surplus in the long run. Second, the firm will certainly only have the ability to break even in the long-run; it will certainly not be able to earn an economic profit.

Long run Equilibrium that Monopolistic Competition: In the long run, a firm in a monopolistic competitive market will product the quantity of items where the lengthy run marginal cost (LRMC) curve intersects marginal revenue (MR). The price will certainly be set where the quantity developed falls ~ above the average revenue (AR) curve. The an outcome is that in the long-term the firm will break even.

Key Takeaways

Key PointsPerfectly compete markets have no barriers of entry or exit. Monopolistically compete markets have actually a couple of barriers of entry and also exit.The two markets are comparable in regards to elasticity of demand, a for sure ‘s ability to make earnings in the long-run, and also how to identify a firm’s benefit maximizing amount condition.In a perfect competitive market, all items are substitutes. In a monopolistically compete market, there is a high degree of product differentiation.Key Termsperfect competition: A kind of industry with countless consumers and also producers, every one of whom space price takers

Perfect competition and monopolistic competition space two species of financial markets.


One the the vital similarities the perfectly competitive and also monopolistically competitive markets share is elasticity of need in the long-run. In both circumstances, the consumers room sensitive come price; if price walk up, demand for the product decreases. The two just differ in degree. Firm’s individual need curves in perfectly competitive industries are perfect elastic, which means that an incremental boost in price will reason demand because that a product to vanish ). Demand curves in monopolistic competition space not perfectly elastic: because of the sector power the firms have, they space able to raise price without losing all of their customers.

Demand curve in a perfect competitive market: This is the demand curve in a perfect competitive market. Keep in mind how any type of increase in price would wipe out demand.

Also, in both set of circumstances the companies cannot make a benefit in the long-run. Ultimately, that company in both sectors will only have the ability to break even by selling their goods and also services.

Both sectors are created of this firm seeking to maximize their profits. In both of this markets, profit maximization occurs once a firm produces goods to together a level so that its marginal prices of production equals its marginal revenues.


One crucial difference in between these two set of economic circumstances is efficiency. A perfectly competitive market is perfect efficient. This way that the price is Pareto optimal, which way that any transition in the price would benefit one party in ~ the cost of the other. The in its entirety economic surplus, i beg your pardon is the sum of the producer and consumer surpluses, is maximized. The suppliers cannot affect the price of the good or company in question; the industry dictates the price. The price the the good or organization in a perfect competitive sector is equal to the marginal expenses of production that good or service.

In a monopolistically competitive market the price is greater than the marginal expense of producing the great or service and also the suppliers deserve to influence the price, giving them industry power. This decreases the customer surplus, and by expansion the market’s economic surplus, and also creates deadweight loss.

Another vital difference in between the two is product differentiation. In a perfectly competitive market commodities are perfect substitutes because that each other. But in monopolistically competitive markets the products are very differentiated. In fact, this firm work tough to emphasize the non-price related differences in between their products and their competitors’.

A final difference involves barriers to entry and also exit. Perfectly competitive markets have actually no obstacles to entry and also exit; a firm have the right to freely get in or leave an industry based upon its perception of the market’s profitability. In a monopolistic competitive market there are couple of barriers to entry and exit, however still an ext than in a perfectly competitive market.

Efficiency that Monopolistic Competition

Monopolistic competitive markets are never effective in any economic sense of the term.

Key Takeaways

Key PointsBecause a great is constantly priced higher than that marginal cost, a monopolistically compete market deserve to never achieve productive or allocative efficiency.Suppliers in monopolistically compete firms will certainly produce below their capacity.Because monopolistic firms set prices higher than marginal costs, customer surplus is considerably less than it would be in a perfect competitive market. This leader to deadweight loss and also an all at once decrease in economic surplus.Key Termsconsumer surplus: The difference in between the preferably price a customer is ready to pay and the actual price they execute pay.producer surplus: The amount that producers advantage by marketing at a sector price that is greater than the shortest price at which they would be willing to sell.

Monopolistically competitive sectors are less efficient than perfectly competitive markets.

Producer and also Consumer Surplus

In state of financial efficiency, this firm that are in monopolistically competitive markets behave an in similar way as monopolistic firms. Both types of firms’ profit maximizing production levels happen when their marginal revenues equals their marginal costs. This amount is much less than what would be developed in a perfectly competitive market. The also way that producers will certainly supply goods below their production capacity.

Firms in a monopolistically competitive industry are price setters, meaning they gain to unilaterally charge every little thing they desire for their goods without being affected by industry forces. In these species of markets, the price that will maximize their profit is collection where the profit maximizing manufacturing level drops on the demand curve.This price over the firm’s marginal costs and also is greater than what the firm would charge if the industry was perfect competitive. This means two things:

Consumers will have to pay a higher price than they would certainly in a perfect competitive market, resulting in a significant decrease in consumer surplus; andProducers will certainly sell less of their items than castle would have actually in a perfect competitive market, which might offset their gains native charging a higher price and also could an outcome in a decline in producer surplus.

Regardless of whether there is a decrease in producer surplus, the ns in customer surplus as result of monopolistic competition promises deadweight loss and an as whole loss in financial surplus.

Inefficiency in Monopolistic Competition: Monopolistic competition create deadweight loss and also inefficiency, as stood for by the yellow triangle. The amount is created when marginal revenue equates to marginal cost, or where the green and blue lines intersect. The price is determined based upon where the quantity falls on the need curve, or the red line. In the brief run, the monopolistic competition industry acts favor a monopoly.

Productive and also Allocative Efficiency

Productive effectiveness occurs as soon as a industry is using all of its sources efficiently. This occurs when a product’s price is collection at its marginal cost, which also equals the product’s average total cost. In a monopolistic vain market, that company always collection the price better than their marginal costs, which method the market have the right to never it is in productively efficient.

Allocative performance occurs once a an excellent is produced at a level that maximizes social welfare. This occurs when a product’s price equals its marginal benefits, i beg your pardon is likewise equal to the product’s marginal costs. Again, due to the fact that a good’s price in a monopolistic compete market constantly exceeds its marginal cost, the market deserve to never be allocatively efficient.

Advertising and Brand monitoring in Monopolistic Competition

Advertising and branding assist firms in monopolistic competitive markets identify their commodities from those of their competitors.

Key Takeaways

Key PointsA company’s brand can help promote quality in that company’s products.Advertising helps educate consumers about products, i beg your pardon decreases an option costs.Costs linked with advertising and also branding include greater prices, customers mislead by false advertisements, and an unfavorable societal influence such together perpetuating stereotypes and also spam.Key Termsbrand: The call of an organization, a product, or a person amongst some segment of the population.advertising: interaction with the function of influencing potential customers about products and also services

One of the features of a monopolistic competitive sector is the each certain must differentiate its products. Two methods to carry out this is v advertising and also cultivating a brand. Heralding is a type of interaction meant to inform, educate, and influence potential customers around products and also services. Declaring is normally used by businesses to cultivate a brand. A brand is a company’s call in relation to commodities or solutions sold under a details name or logo.


Listerine advertisement, 1932: indigenous 1921 until the mid-1970s, Listerine was additionally marketed as preventive and a remedy for colds and also sore throats. In 1976, the Federal profession Commission ruled that these cases were misleading, and also that Listerine had “no efficacy” at either staying clear of or alleviating the symptoms of sore throats and colds. Warner-Lambert to be ordered to avoid making the claims and also to incorporate in the next $10.2 million dollars that Listerine ads details mention the “contrary to prior advertising, Listerine will not help prevent colds or sick throats or lessen your severity. “

Benefits of Advertising and Branding

The purpose of the brand is to generate an immediate positive reaction from consumers as soon as they view a product or business being sold under a details name in order to rise sales. A brand and the associated reputation are built on advertising and also consumers’ previous experiences through the products connected with the brand.

Reputation amongst consumers is important to a monopolistically competitive firm since it is may be the best way to identify itself native its competitors. However, for that reputation to be maintained, the firm need to ensure that the products linked with the brand name room of the highest possible quality. This typical of quality have to be kept at every times since it only takes one poor experience to destroy the worth of the brand because that a segment of consumers. Brands and also advertising have the right to thus assist guarantee quality commodities for consumers and society at large.

Advertising is also beneficial to culture because it helps notify consumers. Markets work best when consumers space well informed, and also advertising provides that information. Advertising and also brands can help minimize the costs of choosing in between different products since of consumers’ familiarity through the firms and also their quality.

Finally, advertising allows new firms to get in into a market. Consumers can be doubtful to purchase products with which they space unfamiliar. Advertising have the right to educate and also inform those consumers, making castle comfortable sufficient to offer those commodities a try.

Costs that Advertising and also Branding

There space some concerns about how declaring can damage consumers and society as well. Some believe that advertising and branding induces client to spend much more on products due to the fact that of the name connected with them quite than due to the fact that of rational factors. Further, there is no guarantee the advertisements accurately define products; they deserve to mislead consumers. Finally, advertising have the right to have an unfavorable societal impacts such together the perpetuation of negative stereotypes or the nuisance the “spam. ”
