Perfect competition is a market structure that leads to the Pareto-efficient allocation of economic resources. Market structure is determined by the number and size distribution of firms in a market, entry conditions, and the extent of product differentiation. The major types of market structure include the following:. Perfect competition leads to the Pareto-efficient allocation of economic resources. Because of this it serves as a natural benchmark against which to contrast other market structures. However, in practice, very few industries can be described as perfectly competitive. Nevertheless, it is used because it provides important insights.

Short Run Equilibrium of a Firm under Perfect Competition | Markets

Monopolistic competition is the economic market model with many sellers selling similar, but not identical, products. The demand curve of monopolistic competition is elastic because although the firms are selling differentiated products, many are still close substitutes, so if one firm raises its price too high, many of its customers will switch to products made by other firms. This elasticity of demand is like pure competition where elasticity is perfect. Demand is not perfectly elastic because a monopolistic competitor has fewer rivals than would be the case for perfect competition , and because the products are differentiated to some degree, so they are not perfect substitutes. Monopolistic competition has a downward sloping demand curve. Thus, just as for a pure monopoly , its marginal revenue will always be less than the market price, because it can only increase demand by lowering prices, but by doing so, it must lower the prices of all units of its product. If average total cost is below the market price, then the firm will earn an economic profit.

In economics the long run is a theoretical concept in which all markets are in equilibrium , and all prices and quantities have fully adjusted and are in equilibrium. The long run contrasts with the short run , in which there are some constraints and markets are not fully in equilibrium. More specifically, in microeconomics there are no fixed factors of production in the long run, and there is enough time for adjustment so that there are no constraints preventing changing the output level by changing the capital stock or by entering or leaving an industry. This contrasts with the short run, where some factors are variable dependent on the quantity produced and others are fixed paid once , constraining entry or exit from an industry. In macroeconomics , the long run is the period when the general price level , contractual wage rates, and expectations adjust fully to the state of the economy, in contrast to the short run when these variables may not fully adjust.

In this article we will discuss about the short run and long run equilibrium of the firm. The short run is a period of time in which the firm can vary its output by changing the variable factors of production in order to earn maximum profits or to incur minimum losses. The number of firms in the industry is fixed because neither the existing firms can leave nor new firms can enter it. The firm is in equilibrium when it is earning maximum profits as the difference between its total revenue and total cost. The price at which each firm sells its output is set by the market forces of demand and supply. Each firm will be able to sell as much as it chooses at that price.

Monopolistic Competition: Short-Run Profits and Losses, and Long-Run Equilibrium

We assume that the goal of the firm is to earn the maximum profit. By the profit of the firm, we shall mean the profit in excess of normal profit which may also be called the pure profit or the economic profit. We know that, in the short run, the firm may increase the quantity produced of its output q by increasing the use of the variable inputs.

Monopolistic competition is a type of imperfect competition such that there are many producers competing against each other, but selling products that are differentiated from one another e. In monopolistic competition, a firm takes the prices charged by its rivals as given and ignores the impact of its own prices on the prices of other firms. Unlike perfect competition , the firm maintains spare capacity. Models of monopolistic competition are often used to model industries.

The long run is a period of time which is sufficiently long to allow the firms to make changes in all factors of production. In the long run, all factors are variable and none fixed.

Ему предложили исчезнуть. - Диагностика, черт меня дери! - бормотал Чатрукьян, направляясь в свою лабораторию.  - Что же это за цикличная функция, над которой три миллиона процессоров бьются уже шестнадцать часов. Он постоял в нерешительности, раздумывая, не следует ли поставить в известность начальника лаборатории безопасности. Да будь они прокляты, эти криптографы. Ничего не понимают в системах безопасности. Присяга, которую Чатрукьян принимал, поступая на службу в АНБ, стала непроизвольно прокручиваться в его голове.

Дрожа от нетерпения, Сьюзан вылетела в Вашингтон. В международном аэропорту Далласа девушку встретил шофер АНБ, доставивший ее в Форт-Мид. В тот год аналогичное приглашение получили еще сорок кандидатов. Двадцативосьмилетняя Сьюзан оказалась среди них младшей и к тому же единственной женщиной.

Он не знал ни где он находится, ни кто его преследует и мчался, подгоняемый инстинктом самосохранения. Он не чувствовал никакой боли - один лишь страх. Пуля ударила в кафельную плитку азульехо чуть сзади. Осколки посыпались вниз и попали ему в шею. Беккер рванулся влево, в другую улочку. Он слышал собственный крик о помощи, но, кроме стука ботинок сзади и учащенного дыхания, утренняя тишина не нарушалась ничем. Беккер почувствовал жжение в боку.

Почему вы не позвонили мне раньше. - Честно говоря, - нахмурился Стратмор, - я вообще не собирался этого делать. Мне не хотелось никого в это впутывать.

Хорошо, - сказал Фонтейн.  - Докладывайте. В задней части комнаты Сьюзан Флетчер отчаянно пыталась совладать с охватившим ее чувством невыносимого одиночества. Она тихо плакала, закрыв. В ушах у нее раздавался непрекращающийся звон, а все тело словно онемело.

    Under perfect competition, price determination takes place at the level of industry while firm behaves as a price taker.

    Producers in monopolistically competitive markets, as well as all market types, are profit maximizers.
