Introduction
Market structure is best defined as the organizational and other characteristics of a market. We focus on those characteristics which affect the nature of competition and pricing.Traditionally, the most important features of market structure are:
1. Number of Buyers and Sellers:
Number of buyers and sellers of a commodity in the market indicates the influence exercised by them on the price of the commodity. In case of large number of buyers and sellers, an individual buyer or seller is not in the position to influence the price of the commodity. However, if there is a single seller of a commodity, then such a seller exercises great control over the price.
2. Nature of the Commodity:
If the commodity is of homogeneous nature, i.e. identical in all respects, then it is sold at a uniform price. However, if the commodity is of differentiated nature (like different brands of toothpaste), then it may be sold at different prices. Again, if the commodity has no close substitutes (like Railways), then the seller can charge higher price from the buyers.
3. Freedom of Movement of Firms:
If there is freedom of entry and exit of firms, then price will be stable in the market. However, if there are restrictions on entry of new firms and exit of old firms, then a firm can influence the price as it has no fear of competition from other or new firms.
4. Knowledge of Market Conditions:
If buyers and sellers have perfect knowledge about the market conditions, then a uniform price prevails in the market. However, in case of imperfect knowledge, sellers

    Text materials Amacher, R., & Pate, J. (2013) chapter 9 expound on the characteristic of perfect competition. the text stretches the importance of the six basic assumptions for the model of perfect competition which are large number of sellers, large number of buyers, homogeneous product, free entry into and free exit out of the market, and resources can easily move in and out of the industry. These six assumptions is a must, for perfect competition to exist. Unfortunately in our world ,it is very difficult for perfect competition to exist, but there are market that comes close, for example currency market would be close to perfect competition. Same product, many sellers and buyers, the down side is the market can be influences by external factors. High entry barriers would make profit difficult, long run equilibrium with perfect competition would be affected. It also means all firms would not be at the optimal size, unable to combined variable resources efficiently. There are competitive pressure when it comes to high barrier to entry in perfect competition, when it is difficult to get in a competitive market, firms create clever way to get in and sometime that involve corruption, for example, the taxi cab industry.…

    In a competitive market there are many firms that supply the same product, such as local gas stations. Mankiw (2007) stated, “You may recall that a market is competitive if each buyer and seller is small compared to the size of the market and, therefore, has little ability to influence market prices” (p. 289). A firm has market power when it is capable of influencing the market price. In a competitive market, the market determines the price the sellers will charge. Mankiw (2007) stated, “In particular, if firms are competitive and profit maximizing, the price of a good equals the marginal cost of making that good” (p. 306). If the seller charges less than the market price, they may sell more. If they raise the cost, they risk losing customers. The output in a competitive market is determined by what will make them have the largest profit. Firms figure this out be comparing the marginal revenue and marginal cost of each unit they produce. When marginal revenue is greater than the marginal cost, the output should be increased so the firm can make a larger profit. They should produce less when the marginal revenue is less than the marginal cost because they will not be making a profit at all. In a competitive market, there is a free entry and exit in the market. The only thing that would keep a firm from entering the market in a competitive firm is if the decision is not profitable to them. The firm will know the decision to enter is profitable if the average total cost of producing the good is less than the price of the good. Mankiw (2007) stated, “In this long-run equilibrium, all firms produce at the efficient scale, price equals the minimum of average total cost, and the number of firms…

    Three market structures involving monopolies, oligopolies, and competitive markets make up the economy in the United States. Each market has different characteristics making each an important part of the economy. Maximum profits are received in a monopoly market because of its control over the market, an oligopoly market also has a large amount of control but profits are reduced because some competition is present, and a competitive market realizes the least profit potential for any company though it is the largest market structure. Each market has its own method of determining how much of a product or service to produce, how much money the product or service is worth, and the level of difficulty for another company to enter that particular market structure.…

    The perfectly competitive market is a market in which economic forces operate unimpeded. There are also factors that must occur for a truly perfect competitive market to exist. The first factor is that both buyers and sellers must be price takers. Price takers are those who take the price determined by market supply and demand as given. The next factor of a perfectly competitive market is that there are a large number of companies. Companies need to be large enough to ensure what happens to one company will not influence the business of the other companies. Another factor to a perfectly competitive market is that no barriers exist for entry into the industry. This includes social, political and economic barriers being nonexistent. Products in a perfectly competitive market must be identical, absolutely no distinguishing factors. Complete information must be accessible to everyone in the market to facilitate a perfectly competitive market. Information like prices, products and available technology must be made available by the companies to other companies and individuals. The final factor in securing a perfectly competitive market is that selling firms are profit maximizing entrepreneurial companies. This ensures…

    Ideal concepts, when implemented into the real world, very often fail to survive. The perfectly competitive market structure is not an exception. The model is based on such strict assumptions that its adaptation into everyday life situations, in most cases, is simply impossible; however it is often described as the ideal. In the long-run, when all the factors of production can vary, given that the maximalisation of earnings is a natural goal behind every firm’s activities, only under the perfectly competitive market’s conditions, is a firm able to reach optimum revenue and, at the same time, be totally efficient. To fully understand this phenomenon it’s necessary to first define productive and allocative efficiency in order to clearly recognize the conditions under which both of them can be achieved. Next, we should focus on how perfect competition differs from monopolistic competition, oligopoly and monopoly. This will allow us to see to what extent a firm’s resources allocation is simply determined by the market structure in which it performs. Such overview will clearly show why in the long-run, in terms of resource allocation, perfect competition is often described as the ideal market structure, and how certain market structures due to their characteristics can prevent the firms from achieving optimum efficiency.…

    Types of Market Structure In the real world there is a mind-boggling array of different markets. • In some markets, producers are extremely competitive (e.g. grain) • In other markets, producers somehow coordinate actions to avoid directly competing with each other (e.g. breakfast cereals) • In others, there is no competition (e.g. flights out of Tweed-New Haven airport). In general we classify market structures into four types: • perfect competition – many producers of a single, unique good. • monopoly - single producer of an unique good (e.g. cable TV, diamonds, particular drugs) • monopolistic competition – many producers of slightly differentiated goods (e.g. fast food) • oligopoly – few producers, with a single or only slightly differentiated good (e.g. cigarettes, cell phones, BDL to ORD flights)…

    Market is often known as physical places, such as supermarket or shopping mall (TheFreeDictionary,1963). Market is a place for buyers (who determined the demand of products) and sellers (who determined the supply of goods) to trade goods and services. It is also a place for operation the forces of demand and supply(BusinessDictionary.com,1910). According to market structure, there is various types of market such as perfect competition market, monopoly market, oligopoly market and so forth (Michael Quayle,Timothy Robinson,William McEachern,1994). Market has two categories, which is perfect competition market and imperfect competition market. Imperfect competition market includes monopolistic competition, oligopoly, duopoly and monopoly. The sizes of these markets are in ascending order, which means the number of firms of the perfect competition is the most and the monopoly is the least (R.Schiler,1943).…

    Monopolistic Competition

    A market is an economic environment in which buyers and sellers in an industry operate. There are four degrees of competition in the market: monopoly, oligopoly, monopolistic competition and perfect competition. As firm numbers rise from one single firm dominating the market in a monopoly to many small firms in perfect competition, the less influence an individual firm’s supply has on total supply and therefore on price because it competes with a large number of other firms.…
