6.1 The essence of competition. The theory of perfect and imperfect competition

Competition means competition between the individual subjects of the market economy for the most favorable terms of production and sales of goods.

The essence of competition is manifested in the following of its features:

• Regulatory - providing products focus on the needs of society, as without it you cannot get income (produce only what will be able to sell, and do not try to sell something that failed to produce);

• Innovation - promoting growth in production efficiency through the use of the achievements of scientific and technical progress;

• allocative (feature location) - the efficient allocation of resources between sectors of production in line with demand and profit margins;

• Sanitize - the elimination of non-competitive enterprises;

• Promotional - lower prices and higher quality.

The following types of competition:

• functional (competition of certain goods);

• competition in price and quality;

• inter-company (among individual firms, industries);

• intra-and inter-branch;

• perfect and imperfect.

The concept of "perfect competition" has a special role in economic theory. The reason is that the studies of perfect competition market explain situations that are not spond to the requirements of that structure. Market is perfect (or as they often say - pure) competition serves a starting point and a benchmark for comparison with other types of market and therefore is estimated to be the ideal market structure ra. This allows you to clearly define the system of constraints faced by each firm in the ways of maximizing profit.

Perfect competition is "perfect" it is in the sense that the organization of the market every firm washes to sell at the market price of products as much as she wants, and the level of prices can not affect any single vendor or single buyer.

Main Characteristics of perfect competition:

1. On the market at the same time there are many firms, each of which occupies a small share of the market

"Smallness" of economic agents means that the volume of demand and supply is extremely small relative to the scale of the market and the change can not affect the market price of the product. The latter is determined only by the set of buyers and sellers, i.e., supply and demand, and can be considered in equilibrium. It is clear that the "set" of market and involves a huge amount, it cannot lead to collusion between them in order to gain monopoly advantages.

2. Homogeneity of products

In presenting the buyer and seller, all units pa goods are exactly the same, are identical and the market floor completely depersonalized. The buyer will still have any seller get the goods, because the product is the same. Therefore, the only governmental incentive for the buyer to the seller performs price.

Perfectly-competitive market - the market price con competition.

Homogeneity of products, and the smallness of the plurality of independent economic actors in the market of perfect competition is the basis for the following important assumptions.
