The firm still retains its capital assets; however, the firm cannot leave the industry or avoid its fixed costs in the short run. Both markets are composed of firms seeking to maximize their profits. It requires neither extension nor retrenchment. In part A of the Figure, the equilibrium of the industry has been shown. In the short run, a monopolistically competitive market is inefficient.
It follows that when the industry is in long-run equilibrium, each firm in the industry is also in long-run equilibrium. Meaning of Firm and Industry 2. Monopolistic competition is different from a monopoly. If some firms are incurring losses, some of the firms will leave the industry till all earn normal profits. Models of monopolistic competition are often used to model industries. This may require a little more explanation. The first clause entails that the average cost curves overlap with the average revenue curves of all the firms in the industry.
Clothing: The clothing industry is monopolistically competitive because firms have differentiated products and market power. The rule is conventionally stated in terms of price average revenue and average variable costs. Hence, the diminishing cost conditions are accorded a lower priority in analysis. Price determination will take place at this level only. Thus in the long-run all costs are variable and there are no fixed costs.
In these scenarios, individual firms have some element of market power: Though monopolists are constrained by , they are not price takers, but instead either price-setters or quantity setters. On this few economists, it would seem, would disagree, even among the neoclassical ones. In part B of Figure, equilibrium of the firm has been shown. The plants of firms are equal, having given technology. In both of these markets, profit maximization occurs when a firm produces goods to such a level so that its marginal costs of production equals its marginal revenues. The real estate market is an example of a very imperfect market.
Normally, a firm that introduces a differentiated product can initially secure a temporary market power for a short while See. So the firm must shut-down here and the point S is referred to as the shut-down point in the diagram. In the absence of externalities and public goods, perfectly competitive equilibria are Pareto-efficient, i. B they do so because there is insufficient product differentiation. Moreover, in the short run, new firms can neither enter the industry nor the existing firms can leave it. Equilibrium of the Firm: Meaning : A firm is in equilibrium when it has no tendency to change its level of output.
It will give rise to a super normal profit and, hence, facilitate new firms to enter and existing firms to expand plant size. Under the circumstances each firm of a given industry, in equilibrium may get either: i Super normal profit. Furthermore, the product on offer is very homogeneous, with the only differences between individual bets being the pay-off and the horse. Differentiation affects performance primarily by reducing direct competition. There is no incentive for firms to leave the industry or for new firms to enter it.

Even then, the industry is in short-run equilibrium when its quantity demanded and quantities supplied are equal at the price which clears the market.
Therefore, all costs are variable. Further, equilibrium has to be discussed both in short run and long run. Under a perfectly competitive industry, these two conditions must be satisfied at the point of equilibrium, i. Even then, the industry is in short- run equilibrium when its quantity demanded and quantity supplied are equal at the price which clears the market. On the other hand, the firm may change, in the long run, the use of all the inputs, variable and fixed, by required amounts to increase its q. Firms are of different efficiency.
As a result, some of the firms will leave the industry so that no firm earns more than normal profits. The first source of inefficiency is due to the fact that at its optimum output, the firm charges a price that exceeds marginal costs. Further, each firm will adjust its plant size so as to produce at a minimum average cost. With lower barriers, new firms can enter the market again, making the long run equilibrium much more like that of a competitive industry, with no economic profit for firms. New firms will continue to enter the industry until the price of the product is lowered to the point that it is the same as the average cost of producing the product, and all of the economic profit disappears. This is also initial long run equilibrium and, hence, will be represented by a point on the long run supply curve.
