List of Partners vendors. 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. Purely monopolistic markets are extremely rare and perhaps even impossible in the absence of absolute barriers to entry, such as a ban on competition or sole possession of all natural resources.
In a market that experiences perfect competition , prices are dictated by supply and demand. Firms in a perfectly competitive market are all price takers because no one firm has enough market control. Unlike a monopolistic market, firms in a perfectly competitive market have a small market share. Barriers to entry are relatively low, and firms can enter and exit the market easily. Contrary to a monopolistic market, a perfectly competitive market has many buyers and sellers, and consumers can choose where they buy their goods and services.
While this market has some similarities to an Oligopoly which we will not explore in this course , it is often classified as a monopolistic competition. Would you switch to another company?
Likely not. This means that the cellular market is certainly not perfectly competitive as cell phone companies have some ability to change prices. Therefore, the demand faced by each of the cellular companies will be more elastic than market demand, but not perfectly elastic. Rogers faces a downward sloping demand curve and has ATC and MC curves similar to the ones we have seen before.
The monopolistically competitive firm decides on its profit-maximizing quantity and price similar to the way that a monopolist does. Step 1. Rogers determines its profit-maximizing level of output.
Two situations are possible:. Step 2. Rogers decides what price to charge. When the firm has determined its profit-maximizing quantity of output, it will behave like a monopoly and charge the maximum it can at the quantity. Remember that in monopolistic competition, there are few barriers to entry. Since Rogers is earning positive economic profits, other firms will be tempted to enter the market.
The entry of other firms into the same general market 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. When will this shifting stop? When profits are 0. As shown in Figure 8. What about the social surplus?
Although profits are now 0, a deadweight loss persists. Notice also that ATC is not at a minimum. This is the price the market pays for variety since the aggregate market does not ensure the most efficient production when there is slight differentiation in products.
Even though monopolistic competition does not provide efficiency, it does have benefits of its own. Product differentiation is based on variety and innovation. The relationship between marginal revenue and price in a monopolistic market is best understood by considering a numerical example, such as the one provided in Table. As the price falls, the market's demand for output increases, in keeping with the law of demand. The third column reports the total revenue that the monopolist receives from each different level of output.
The fourth column reports the monopolist's marginal revenue that is just the change in total revenue per 1 unit change of output. Note that the monopolist's marginal revenue is declining as output increases. Now, consider what happens when the monopolist increases its output to 3 units.
Assume that there are two countries, each with a monopolistically competitive industry producing a differentiated product. Suppose initially that the two countries are in autarky. For convenience, we will assume that the firms in the industry are symmetric relative to the other firms in the industry. Note that the assumptions about symmetry are made merely for tractability. It is much simpler to conceive of the model results when we assume that all firms are the same in their essential characteristics.
However, it seems likely that these results would still be obtained even if firms were asymmetric. In Figure 6. The firm faces a downward-sloping demand curve D 1 for its product and maximizes profit by choosing that quantity of output such that marginal revenue MR 1 is equal to marginal cost MC.
This occurs at output level Q 1 for the representative firm. The firm chooses the price for its product, P 1 , that will clear the market. Notice that the average cost curve AC is just tangent to the demand curve at output Q 1. Thus the firm is in a long-run equilibrium since entry or exit has driven profits to zero. Figure 6. Keep in mind that this is the equilibrium for just one of many similar firms producing in the industry.
