Economics Perfect Competition and Monopolistic Competition
1a) Perfect competition describes a market structure whose assumptions are extremely strong and highly unlikely to exist in most real-time and real-world markets. In perfect competition, there are a large number of firms in the industry. The firms in this industry are price takers as they sell at whatever price is set by demand and supply in the industry as a whole. All the firms produce homogeneous products which are exactly identical; it is impossible to distinguish between a good produced in one firm and a good produced in another firm. There are no barriers to entry or exit ; firms can enter or exit the market when they want to, however they don't have ability to stop new firms from entering and old firms from leaving the industry. Producers and consumers have perfect knowledge of the market i.e. the producers are fully aware of market prices, cost in the industry, and the workings of the market and the consumers are fully aware of prices in the market, the quality of the products, and the availability of the goods. Monopolistic competition is a market structure with many competed firms and each firm has a little bit of market power to set prices. The industry is made up of large number of firms and each firm is able to set prices and therefore it has a downward sloping demand curve. There is free entry and exit of firms in response to profits in the industry. Each firm produces a product that is differentiated from all other products produced by the other firms in the industry and it is possible for consumers to tell one firm's product from another. Gaining abnormal profits is possible in short run but not in long run in the monopolistic competition market

3) In monopolistic competition Marginal Curve (MC) is below the Average Revenue curve (AR). Consumers have more additional benefit than the additional cost of production. Not allocatively efficient
Monopolistic Competition Firms may not produce at the lowest possible cost (not productively efficient), but society gets a variety in return. Monopolistic competitive industry is made up of a fairly large number of firms. In relation to the size of the Industry, monopolistic competitive firms are small. They produce slightly differentiated products, for example by brand name, color, design and quality of service. A firm in monopolistic competition has a downward sloping demand curve, since they are price-makers, which means that they are influential enough to affect the price of their product. The demand curve is relatively elastic because of the many substitutes (which are slightly different). A monopolistic competitive firm is able to gain abnormal profits in the short run. In this case the firm is maximizing profits by producing at the level of output where MC=MR. On the diagram below, q1 represents the productively efficient level. Productive efficiency is achieved when the marginal cost is at the lowest average total Cost. This means a productively efficient firm utilizes all its resources and produces at the lowest cost possible. A monopolistic competitive firm is allocatively efficient when the marginal cost curve intersect the average revenue curve. This is because the price consumers are willing to pay equals to the marginal utility they receive. So a firm is allocatively efficient when there is an optimal distribution of the product. It's also called the socially optimum level of output. In this case, when a firm in monopolistic competition is earning abnormal profits, it is neither productively efficient, nor allocatively efficient. This is because the firm produces where marginal costs is equal to the marginal revenue, as opposed to the points of productive and allocatively efficiency which are located differently.

    A monopolist is the market 's only supplier; the demand curve the monopolist faces is the market demand curve. The market demand curve is downward sloping, reflecting the law of demand. The fact that the monopolist faces a downward-sloping demand curve means that the price a monopolist can expect to receive for its output will not remain constant as the monopolist increases its output (Cliffnotes.com, 2012). The demand…

    Perfect competition is the situation in a market (based on six assumptions), (1) where the elements of a monopoly are non-existent, (2) consisting of numerous buyers and sellers, (3) the market price of commodities are beyond the control of individual sellers and buyers, (4) perfectly competitive firms produce homogeneous products, (5) there is free entry into the market and free exit out of the market, and lastly (6) there is perfect knowledge. If these six assumptions are met, the market will be perfectly competitive.…

    Perfect competition describes how a set of companies aren’t big enough to control a big chunk of the economic market. There are 4 market characteristics of a perfect competition include a large number of small firms, identical products made sold by all firms, easy to enter and exit the industry market and perfect knowledge of prices and technology. The price in a perfect market is always dictated by the consumers, the output or quality is determined by the producers. There isn’t much room to change prices to beat off competitors as your margins become very small, and if you do not sell much you probably won’t break even. The quality may be a little different, but wouldn’t be significant enough to let the company grow.…

    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.…

    There are a variety of different business structures that comprise the market in the world today. The most common ones found in the business world today are sole proprietorships, partnerships, and corporations. From these you will also find monopolies and oligopolies. Economists assume there are a number of different buyers and sellers in the market which leads to competition which allows prices to change in response to changes in supply and demand.(1) In many industries you there are substitutes for products, so if one type of product becomes too expensive the consumer can choose an alternative product that is cheaper, or one of better quality. This is called perfect competition within different companies. However, in some industries there are no substitutes for a product. In a market with only one supplier of a good or service, the producer can control the price meaning that the consumer does not have a choice, cannot maximize his or her total utility, and has very little to no influence over the price of the good or service they require. This is called a monopoly, where the single business is the industry. In slight contrast, you have the oligopoly which is at least two companies competing for market share. In an oligopoly, products are usually very similar, if not identical to each other, and in order to make their product more attractive they will lower their prices, forcing the other one out of the market until that firm lowers their price. Finally, the fourth type of business structure is called monopolistic competition. Like an oligopoly, these firms produce similar or identical products where substitute products usually aren’t available, although monopolistic competition is between many firms, where an oligopoly is usually two or three different companies controlling the market. In monopolistic competition, a firm takes the prices charged by its rivals as given…

    Perfect competition describes several small firms competing with one another, many products, many buyers and sellers, and many substitutes. Prices are determined by supply and demand and the producer has no leverage. In a monopoly there is only one producer or seller for a product. Competition to monopolies may be limited to high prices or copyrights. In the oligopoly market…

    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…

    They are considered price takers and it has a downward sloping demand curve, the market demand cure and is free to choose its price and quantity according to market demand. In a perfectly competitive market, there is a market price. Market revenue is equal to price in the market, every additional unit that is sold brings the market price. Monopolies are still profit maximizing firms and are going to satisfy profit maximizing condition that marginal cost + marginal revenue. Antitrust laws are put into place to promote competition and benefits consumers with lower prices, higher quality products and services, as well as more of a choice.…

    The perfectly competitive firm faces a demand curve that is horizontal at the prevailing market price. This is the result of firms in the industry producing a commodity. No individual firm would want to raise its price above its competitors priceswhich is the market price. If it raised them, its customers would switch all of their purchases to competing firms, and the first firms sales would drop to zero.…

    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…

    Monopolistic competition is characterized by a relatively large number of sellers producing differentiated products (clothing, furniture, books). There is widespread nonprice competition, a selling strategy in which one firm tries to distinguish its product or service from all competing products on the basis of attributes like design and workmanship (an approach called product differentiation).(McConnell and Bruce, 2004, Chapter 23, pg. 3)…

    The model of monopolistic competition describes a common market structure in which firms have many competitors, but each one sells a slightly different product. If there was no differentiation, the competition would turn into perfect competition. In effect, monopolistic competition is something of a hybrid between perfect competition and monopoly. Comparable to perfect competition, monopolistic competition contains a large number of extremely competitive firms. However, comparable to monopoly, each firm has market control and faces a negatively-sloped demand curve. Monopolistic competition as a market structure was first identified in the 1930s by American economist Edward Chamberlin, and English economist Joan Robinson.…

    Pure competition is defined by the economists as one of the four market structures in industries. Theoretically, pure competitive markets provide the foundation of supply and demand and prices in such markets would normally move instantaneously to equilibrium. What type of goods represents "pure competition" market? According to the text, the most common examples are fish products and agricultural commodities such as oats, corn, grains, carrots, eggs and other such products (McConnell & Brue, 2004, p.6). All these products in the pure competitive markets have several characteristics in common. First of all, the products are sold in competitive markets where there are a large number of small producer and buyers. Secondly, the products are fairly standardized, in another word, there is no product differentiation. The corns grow in Iowa is truly no different from corns from California. Thirdly, sellers of those products are at the mercy of the market in terms of price, that is, each seller is a price taker as the price is only determined by supply and demand in the market as a whole. A single seller can not change the price freely on a product because the identical product is available to the consumers from hundreds of competitors in the same market. Lastly, any firm can easily enter and exit the industry as wishes mainly because there is no significant overhead, advertising expenses, and legal and technological obstacles.…

    In a perfectly competitive market, producers are price-takers and consumers are price-takers. There are many producers, none having a large market share and the industry produces a standardized product, also free entry and exit of the industry. They produce using the optimal output rule: produce where marginal revenue equals marginal cost as Smith (1904) demonstrated.…
