Resources will not be wasted through advertising because products are homogenous 5. Many economists are highly critical of the neoclassical reliance on perfect competition. For example, selling a popular good on the internet through a service like e-bay is close to perfect competition.
In a perfectly competitive market, the demand curve facing a firm is perfectly elastic. For the former, absence of perfect competition in labour marketse.
Free software may be bought or sold at whatever price that the market may allow. The basic reason is that no productive factor with a non-zero marginal product is left unutilized, and the units of each factor are so allocated as to yield the same indirect marginal utility in all uses, a basic efficiency condition if this indirect marginal utility were higher in one use than in other ones, a Pareto improvement could be achieved by transferring a small amount of the factor to the use where it yields a higher marginal utility.
Thus when the issue is normal, or long-period, product prices, differences on the validity of the perfect competition assumption do not appear to imply important differences on the existence or not of a tendency of rates of return toward uniformity as long as entry is possible, and what is found fundamentally lacking in the perfect competition model is the absence of marketing expenses and innovation as causes of costs that do enter normal average cost.
Normally, a firm that introduces a differentiated product can initially secure a temporary market power for a short while See "Persistence" in Monopoly Profit. Free entry and exit: Think for a moment, what industry is actually like this? These criticisms point to the frequent lack of realism of the assumptions of product homogeneity and impossibility to differentiate it, but apart from this the accusation of passivity appears correct only for short-period or very-short-period analyses, in long-period analyses the inability of price to diverge from the natural or long-period price is due to active reactions of entry or exit.
There will be good information about relative prices. Because there is freedom of entry and exit and perfect information, firms will make normal profits and prices will be kept low by competitive pressures.
The second group argues that perfect competition is not even a desirable theoretical outcome. Hayek argued that perfect competition had no claim to be called "competition. The flaw in considering the stock exchange as an example of Perfect Competition is the fact that large institutional investors e.
Many economists are highly critical of the neoclassical reliance on perfect competition. Economic profit is, however, much more prevalent in uncompetitive markets such as in a perfect monopoly or oligopoly situation.
Many other smaller schools of thought disagree. Anyone is free to enter and leave the market at no cost. Profit can, however, occur in competitive and contestable markets in the short run, as firms jostle for market position. The demand curve for the industry is not perfectly elastic, it only appears that way to the individual firms, since they must take the market price no matter what quantity they produce.
Some economists have a different kind of criticism concerning perfect competition model. Normal profit means consumers are getting the lowest price. Although a regulated firm will not have an economic profit as large as it would in an unregulated situation, it can still make profits well above a competitive firm in a truly competitive market.
The commercial buyers of agricultural commodities are generally very well-informed and, although agricultural production involves some barriers to entry, it is not particularly difficult to enter the marketplace as a producer. The firm should not produce, but should shut down in the short run if its loss exceeds its fixed costs.
There is no need for government to intervene or even exist. No externalities — Costs or benefits of an activity do not affect third parties. The basic reason is that no productive factor with a non-zero marginal product is left unutilized, and the units of each factor are so allocated as to yield the same indirect marginal utility in all uses, a basic efficiency condition if this indirect marginal utility were higher in one use than in other ones, a Pareto improvement could be achieved by transferring a small amount of the factor to the use where it yields a higher marginal utility.
Well defined property rights — These determine what may be sold, as well as what rights are conferred on the buyer. For example advertising convinces people that two goods that are fundamentally the same are actually different. Homogeneous products — The products are perfect substitutes for each other, i.

Perfect competition is rare in the real world, but the model is important because it helps analyze industries with characteristics similar to pure competition This model provides a context in which to apply revenue and cost concepts developed in the previous lecture.
CHAPTER 4: PERFECT COMPETITION. LEARNING OBJECTIVE Examples of markets in perfect competition are extremely rare. Numerous markets in the retail, service and agricultural sectors The firms in perfect competition have no power over price: they have to sell at the going market price.
