1. A perfectly competitive market has the following characteristics.
(i) The market consists of buyers and sellers who are price takers.
(ii) Each firm in the market produces undifferentiated and homogenous products.
(iii) Buyers and sellers have perfect information about the price prevailing in the mark! About the availability of commodities at any given point of time.
(iv) Firms can enter or exit the market freely.
Implications:
The implications of all these features is that there is single price in the mark no individual buyer can change it. On this price a firm can sell any amount of output. Because of flu demand of a firm is perfectly elastic and hence a horizontal line at the market price. Another implication is that a firm will produce only when it is profitable to produce, otherwise it will stop the products.

Perfectly Competitive Markets

...Perfectly Competitive Markets A firm’s decision about how much to produce or what price to charge depends on how competitive the market structure is. If the Dangote cement raise their prices by 5%, there will be a small reduction in the quantity of cements demanded. If the conoil gas station raises its gasoline prices by 5%, there will be a huge reduction in the gas demanded. In a very competitive market like the local gasoline market, a single station has very little choice in what price to charge. If the station is busy there is no reason to lower the price, but if it raises its price by 10 cents a gallon, it will have almost no customers. We will study the extreme case of perfect competition, where firms are “price takers.” In a perfectly competitive market, (i) there are many buyers and sellers, so each buyer or seller is a price taker, (ii) all sellers supply the same, identical product. This is the model of supply and demand. If a seller could influence the price, it would not be acting according to a supply curve. In the long run, we also require that (iii) firms can freely enter or exit the market. Revenue of a Competitive Firm For a competitive firm, the price it receives does not depend on the quantity it chooses to sell. Marginal revenue equals the price of its output. For example, if the price is $6, then the total revenue of selling 10 units is $60 and the total revenue of selling 11 units is $66. Marginal revenue, ªTR/ªQ = (66-60)/(11-10)...

Perfectly Competitive Market

...1. What are the characteristics of a perfectly competitive market? What are the implications for accounting profit in a perfectly competitive market? What about economic profit? Perfectly competitive markets are characterized by low sunk costs, perfect information, no entry or exit costs, no search costs, identical products and an infinite numbers of sellers. In a perfectly competitive market there are many firms and many buyers, all of which are price takers, meaning they have no control over prices. As price takers, firms face a highly (perfectly) elastic demand curve, meaning that they can only change revenue by changing the quantity produced. Firms in a perfectly competitive market will produce where MR = MC. Since firms are price takers, MR = Price. As a result, when marginal cost is equal to marginal revenue, it is also equal to price. If firms are realizing positive economic profits, other firms with similar cost structures will have an incentive to enter the market: one competitive firm’s economic profits indicate that production of that good is more profitable than any other available allocation of resources, causing other firms to invest. Once new firms enter the market, there is an increase in the MARKET, or AGGREGATE supply which will change the price that individual firms face, causing a reduction in the price. Firms will enter until economic profits are zero, at which point the intersection of the price and the marginal cost intersects the minimum of...

Perferct Competition

...is a problem that is emerging in a market in which buyers and sellers are informed about all elements of monopoly that are absent and the market price of a commodity is not control by individual buyers and sellers. Perfect competition is simply looked as a market structure where competition is at its greatest possible level. According to Kirzner (2000), “Perfect competition therefore came to mean the situation in markets where each and every participant lacks any power whatever directly to influence product price or product quality”. Perfect competition is used to compare other and real-life market structures. A real life market structure such as agriculture is the industry that closely resembles a perfect competition. The four key characteristics of perfect competition are a large number of small firms, identical products sold by all firms, perfect resource mobility or the freedom of entry into and exit out of the industry, and perfect knowledge of prices and technology. These four characteristics basically describes that a perfectly competitive firm does not have any control over the market. A large number of small firms that produce identical products have a large number of perfect substitutes that exist for the output produced by any given firm. This means the demand curve for a perfectly competitive firm's output is perfectly elastic. Freedom of entry into and exit out of the industry means that capital and other resources are perfectly mobile and that it is not possible...

Principals of Economics Unit

...Unit 3 The Perfectly competitive market is a market structure in which the competition level is very high (Mankiw, 2007). In this market structure, the knowledge is freely available to all buyers and sellers. The availability knowledge enables the consumers and producers to make rational decisions to maximize their profits. Market price is the particular price that buyers and sellers agree to use in the market at a given time. I formal markets, there are two types of prices. These are the selling price and the buying price. The price of the goods in the market determines the market structures (Economics Online, 2015). The increase market products depend on demand and supply. In a perfectly competitive market firm, the price of goods determines the profit. The average revenue is the revenue a firm generates by selling one unit of output. The market structure determines the relationship between the quantity of output and average revenue. In a perfectly competitive market, the average revenue equals both marginal revenue and the price. Both marginal revenue and the prices are constant. A business experiences marginal revenue when it sells one or more extra units of its output. Marginal revenue plays a crucial role in profit maximization decision making (Mankiw, 2007). Therefore, a perfectly competitive market increases its profit by equating marginal revenue. The marginal revenue and the total output rely on market structure. In a perfectly competitive market, the price and...

The demand curve is horizontal for a perfectly competitive firm and is driven by its price. When the price goes up, demand goes down. The market demand curve is the total quantity that individuals are willing to buy at any price, this is downward sloping which reflects the law of demand. 2.

...Nebrida Question 1: Use supply and demand analysis to show the effect of a (binding) price ceiling in the market for rental properties. * What are the possible negative effects due to this price ceiling? The possible negative effects of this price ceiling according to supply and demand analysis is that landlords would have less incentive to offer apartments, and so the supply of apartments would drop, causing a persistent shortage of rental housing. This price ceiling would also lead to inefficiency, meaning that the quality of the housing would lower. * What happens to the total surplus (total surplus = consumers’ surplus + producers’ surplus)? What happens to total surplus when a price ceiling is implemented is deadweight loss. Deadweight loss affects not just consumer and producer surplus, but total surplus. Deadweight loss is the loss in total surplus that occurs when an action or a policy reduces the quantity transacted below the efficient market equilibrium quantity. Wasted resources, inefficient allocation to consumers, and inefficiently low quality lead to a loss of surplus over and above the deadweight loss. * Why do governments use price ceilings despite these negative effects? In some places, price ceilings, or rent control on apartments give a small minority of renters much cheaper than they would get in an unregulated market. Also, sometimes when price ceilings have been in effect for a long time, buyers and renters don’t know the difference...

...competition and the competitive firm. It examines how businesses with a given market price make production decisions that help maximizing profit. Characteristics of Perfect Competition 1. Many firms, each is selling an identical product. Each firm’s output is a perfect substitute for the output of the other firms, so the demand for each firm’s output is perfectly elastic. 2. Large number of buyers who are indifferent from whom to buy 3. No barriers (restrictions) to entry or exit; it is relatively easy to get into the business 4. Each firm produces a very small share of the total output so that no individual firm has the market power to influence the market price of the good it produces. A perfectly competitive firm is a price taker; it takes the market price as given. 5. Firms already in the industry have no advantage over new entrants 6.

...13 Assume that a market was served by an industry which was perfectly competitive when one of the firms was able to gain exclusive control of an essential input so that all of the other businesses closed down leaving the owner of the raw material as the sole supplier in the industry. Assume that there is no change in the demand for the product and that all the costs of production remain the same. a. Use the demand and supply model to show if there is likely to be any significant inefficiencies in production and allocation of the economies resources when there is only a single firm supplying the industry. b. Are there any circumstances when the single firm can lead to an efficient allocation of resources? Give reasons for your answer. a. A perfectly competitive market is defined by the following assumptions: 1.There are many buyers and sellers 2.Firms produce a homogenous product 3.Buyers and sellers are fully informed about the price and availabilty of resorces and products 4.Firms enjoy free entry and exit from the market 5.All resources are completely mobile 6.Firms seek to maximise economic profit, and consumers seek to maximise total utility.
