Why does monopolistic competition exist




















As a result, the market will suffer deadweight loss. The suppliers in this market will also have excess production capacity. Monopolistic competitive markets can lead to significant profits in the short-run, but are inefficient. The most common example of this is the production of a good that requires a factory.

If demand spikes, in the short run you will only be able to produce the amount of good that the capacity of the factory allows. This is because it takes a significant amount of time to either build or acquire a new factory. If demand for the good plummets you can cut production in the factory, but will still have to pay the costs of maintaining the factory and the associated rent or debt associated with acquiring the factory.

You could sell the factory, but again that would take a significant amount of time. In the short run, a monopolistically competitive market is inefficient. It does not achieve allocative nor productive efficiency. Also, since a monopolistic competitive firm has powers over the market that are similar to a monopoly, its profit maximizing level of production will result in a net loss of consumer and producer surplus, creating deadweight loss. Like monopolies, the suppliers in monopolistic competitive markets are price makers and will behave similarly in the short-run.

Also like a monopoly, a monopolistic competitive firm will maximize its profits by producing goods to the point where its marginal revenues equals its marginal costs. The profit maximizing price of the good will be determined based on where the profit-maximizing quantity amount falls on the average revenue curve.

The profit the firm makes is the the amount of the good produced multiplied by the difference between the price minus the average cost of producing the good.. Short Run Equilibrium Under Monopolistic Competition : As you can see from the chart, the firm will produce the quantity Qs where the marginal cost MC curve intersects with the marginal revenue MR curve. The price is set based on where the Qs falls on the average revenue AR curve.

The profit the firm makes in the short term is represented by the grey rectangle, or the quantity produced multiplied by the difference between the price and the average cost of producing the good. Since monopolistically competitive firms have market power, they will produce less and charge more than a firm would under perfect competition. Because of the possibility of large profits in the short-run and relatively low barriers of entry in comparison to perfect markets, markets with monopolistic competition are very attractive to future entrants.

In the long run, firms in monopolistic competitive markets are highly inefficient and can only break even. Given a long enough time period, a firm can take the following actions in response to shifts in demand:. In the long-run, a monopolistically competitive market is inefficient.

It achieves neither allocative nor productive efficiency. Also, since a monopolistic competitive firm has power over the market that is similar to a monopoly, its profit maximizing level of production will result in a net loss of consumer and producer surplus.

Like monopolies, the suppliers in monopolistic competitive markets are price makers and will behave similarly in the long-run. While a monopolistic competitive firm can make a profit in the short-run, the effect of its monopoly-like pricing will cause a decrease in demand in the long-run. This increases the need for firms to differentiate their products, leading to an increase in average total cost. This means two things. First, that the firms in a monopolistic competitive market will produce a surplus in the long run.

Second, the firm will only be able to break even in the long-run; it will not be able to earn an economic profit. Long Run Equilibrium of Monopolistic Competition : In the long run, a firm in a monopolistic competitive market will product the amount of goods where the long run marginal cost LRMC curve intersects marginal revenue MR. The price will be set where the quantity produced falls on the average revenue AR curve.

The result is that in the long-term the firm will break even. The key difference between perfectly competitive markets and monopolistically competitive ones is efficiency.

One of the key similarities that perfectly competitive and monopolistically competitive markets share is elasticity of demand in the long-run. In both circumstances, the consumers are sensitive to price; if price goes up, demand for that product decreases.

The two only differ in degree. Demand curves in monopolistic competition are not perfectly elastic: due to the market power that firms have, they are able to raise prices without losing all of their customers. Demand curve in a perfectly competitive market : This is the demand curve in a perfectly competitive market. Note how any increase in price would wipe out demand. Also, in both sets of circumstances the suppliers cannot make a profit in the long-run. Ultimately, firms in both markets will only be able to break even by selling their goods and services.

Both markets are composed of firms seeking to maximize their profits. In both of these markets, profit maximization occurs when a firm produces goods to such a level so that its marginal costs of production equals its marginal revenues. One key difference between these two set of economic circumstances is efficiency. A perfectly competitive market is perfectly efficient.

This means that the price is Pareto optimal, which means that any shift in the price would benefit one party at the expense of the other. Super-normal profits attract in new entrants, which shifts the demand curve for existing firm to the left. New entrants continue until only normal profit is available. At this point, firms have reached their long run equilibrium. Clearly, the firm benefits most when it is in its short run and will try to stay in the short run by innovating, and further product differentiation.

Monopolistically competitive firms are most common in industries where differentiation is possible, such as:. The existence of monopolistic competition partly explains the survival of small firms in modern economies.

The majority of small firms in the real world operate in markets that could be said to be monopolistically competitive. There is a tendency for excess capacity because firms can never fully exploit their fixed factors because mass production is difficult. This means they are productively inefficient in both the long and short run. However, this is may be outweighed by the advantages of diversity and choice. Select basic ads.

A monopolistic market and a perfectly competitive market are two market structures that have several key distinctions in terms of market share , price control, and barriers to entry.

In a monopolistic market, there is only one firm that dictates the price and supply levels of goods and services, and that firm has total market control. In contrast to a monopolistic market, a perfectly competitive market is composed of many firms, where no one firm has market control. In the real world, no market is purely monopolistic or perfectly competitive. Every real-world market combines elements of both of these market types.

Monopolistic and perfectly competitive markets affect supply, demand, and prices in different ways. In a monopolistic market , firms are price makers because they control the prices of goods and services.

In this type of market, prices are generally high for goods and services because firms have total control of the market. Firms have total market share, which creates difficult entry and exit points. Since barriers to entry in a monopolistic market are high, firms that manage to enter the market are still often dominated by one bigger firm.

A monopolistic market generally involves a single seller, and buyers do not have a choice concerning where to purchase their goods or services. In this example, MR and MC intersect at a quantity of 40, which is the profit-maximizing level of output for the firm. Step 2. The monopolistic competitor decides what price to charge. When the firm has determined its profit-maximizing quantity of output, it can then look to its perceived demand curve to find out what it can charge for that quantity of output.

Profits are total revenues minus total costs, which is the shaded area above the average cost curve. Although the process by which a monopolistic competitor makes decisions about quantity and price is similar to the way in which a monopolist makes such decisions, two differences are worth remembering.

Second, a monopolist is surrounded by barriers to entry and need not fear entry, but a monopolistic competitor who earns profits must expect the entry of firms with similar, but differentiated, products.

If one monopolistic competitor earns positive economic profits, other firms will be tempted to enter the market. A gas station with a great location must worry that other gas stations might open across the street or down the road—and perhaps the new gas stations will sell coffee or have a carwash or some other attraction to lure customers. A successful restaurant with a unique barbecue sauce must be concerned that other restaurants will try to copy the sauce or offer their own unique recipes.

A laundry detergent with a great reputation for quality must be concerned that other competitors may seek to build their own reputations. The entry of other firms into the same general market like gas, restaurants, or detergent shifts the demand curve faced by a monopolistically competitive firm. The shift in marginal revenue will change the profit-maximizing quantity that the firm chooses to produce, since marginal revenue will then equal marginal cost at a lower quantity.

Figure 3 a shows a situation in which a monopolistic competitor was earning a profit with its original perceived demand curve D 0. The intersection of the marginal revenue curve MR 0 and marginal cost curve MC occurs at point S, corresponding to quantity Q 0 , which is associated on the demand curve at point T with price P 0.

The combination of price P 0 and quantity Q 0 lies above the average cost curve, which shows that the firm is earning positive economic profits. Unlike a monopoly, with its high barriers to entry, a monopolistically competitive firm with positive economic profits will attract competition.

Moving vertically up from that quantity on the new demand curve, the optimal price is at P 1. When price is equal to average cost, economic profits are zero. Thus, although a monopolistically competitive firm may earn positive economic profits in the short term, the process of new entry will drive down economic profits to zero in the long run.

Remember that zero economic profit is not equivalent to zero accounting profit. Figure 3 b shows the reverse situation, where a monopolistically competitive firm is originally losing money.

The adjustment to long-run equilibrium is analogous to the previous example. The economic losses lead to firms exiting, which will result in increased demand for this particular firm, and consequently lower losses. Firms exit up to the point where there are no more losses in this market, for example when the demand curve touches the average cost curve, as in point Z.

Monopolistic competitors can make an economic profit or loss in the short run, but in the long run, entry and exit will drive these firms toward a zero economic profit outcome. However, the zero economic profit outcome in monopolistic competition looks different from the zero economic profit outcome in perfect competition in several ways relating both to efficiency and to variety in the market.

The long-term result of entry and exit in a perfectly competitive market is that all firms end up selling at the price level determined by the lowest point on the average cost curve. This outcome is why perfect competition displays productive efficiency : goods are being produced at the lowest possible average cost. However, in monopolistic competition, the end result of entry and exit is that firms end up with a price that lies on the downward-sloping portion of the average cost curve, not at the very bottom of the AC curve.

Thus, monopolistic competition will not be productively efficient. In a perfectly competitive market, each firm produces at a quantity where price is set equal to marginal cost, both in the short run and in the long run. This outcome is why perfect competition displays allocative efficiency: the social benefits of additional production, as measured by the marginal benefit, which is the same as the price, equal the marginal costs to society of that production.

A monopolistically competitive firm does not produce more, which means that society loses the net benefit of those extra units. This is the same argument we made about monopoly, but in this case to a lesser degree. Thus, a monopolistically competitive industry will produce a lower quantity of a good and charge a higher price for it than would a perfectly competitive industry.

See the following Clear It Up feature for more detail on the impact of demand shifts. This information on total revenue is then used to calculate marginal revenue, which is the change in total revenue divided by the change in quantity. A change in perceived demand will change total revenue at every quantity of output and in turn, the change in total revenue will shift marginal revenue at each quantity of output. Thus, when entry occurs in a monopolistically competitive industry, the perceived demand curve for each firm will shift to the left, because a smaller quantity will be demanded at any given price.

Another way of interpreting this shift in demand is to notice that, for each quantity sold, a lower price will be charged. Consequently, the marginal revenue will be lower for each quantity sold—and the marginal revenue curve will shift to the left as well. Conversely, exit causes the perceived demand curve for a monopolistically competitive firm to shift to the right and the corresponding marginal revenue curve to shift right, too. A monopolistically competitive industry does not display productive and allocative efficiency in either the short run, when firms are making economic profits and losses, nor in the long run, when firms are earning zero profits.

Even though monopolistic competition does not provide productive efficiency or allocative efficiency, it does have benefits of its own.
