Can imperfect competition be an efficient market

In an imperfect market , individual buyers and sellers can influence prices and production, there is no full disclosure of information about products and prices, and there are high barriers to entry or exit in the market. A perfect market is characterized by perfect competition, market equilibrium, and an unlimited number of buyers and sellers.

All real-world markets are imperfect. Thus, the study of real markets is always influenced by competition for market share, high barriers to entry and exit, different products and services, prices set by price makers rather than by supply and demand, imperfect or incomplete information about products and prices, and a small number of buyers and sellers.

For example, traders in the financial market do not possess perfect or even identical knowledge about financial products. The traders and assets in a financial market are not perfectly homogeneous. New information is not instantaneously transmitted, and there is a limited velocity of reactions.

When considering the implication of economic activity, economists only use perfect competition models. A such, the term imperfect market is somewhat misleading. Most people will assume an imperfect market is deeply flawed or undesirable. However, this is not always the case. The range of market imperfections is as wide as the range of all real-world markets—some are much or less efficient than others. Not all market imperfections are harmless or natural.

Situations can arise in which too few sellers control too much of a single market, or when prices fail to adequately adjust to material changes in market conditions. It is from these instances that the majority of economic debate originates. Some economists argue that any deviation from perfect competition models justifies government intervention, in order to promote increased efficiency in production or distribution.

Such interventions may come in the form of monetary policy , fiscal policy, or market regulation. One common example of such interventionism is anti-trust law, which is explicitly derived from perfect competition theory. Governments may also use taxation, quotas, licenses, and tariffs to help regulate so-called perfect markets. Other economists argue that government intervention may not always be necessary to correct imperfect markets.

This is because government policy is also imperfect, and government actors may not possess the right incentives or information to interfere correctly. Finally, many economists argue government intervention is rarely, if ever, justified in markets. The Austrian and Chicago schools notably blame many market imperfections on erroneous government intervention.

When at least one condition of a perfect market is not met, it can lead to an imperfect market. Every industry has some form of imperfection. Imperfect competition can be found in the following structures:. This is a structure in which there is only one dominant seller. Products offered by this entity have no substitutes. These markets have high barriers to entry and a single seller who sets the prices on goods and services. Prices can change without notice to consumers.

This structure has many buyers but few sellers. Perfect competition is a concept in microeconomics that describes a market structure controlled entirely by market forces. If and when these forces are not met, the market is said to have imperfect competition. While no market has clearly defined perfect competition, all real-world markets are classified as imperfect. That being said, a perfect market is used as a standard by which the effectiveness and efficiency of real-world markets can be measured.

Perfect competition is an abstract concept that occurs in economics textbooks, but not in the real world. That's because it's impossible to attain in real life.

Theoretically, resources would be divided among companies equally and fairly in a market with perfect competition, and no monopoly would exist. Each company would have the same industry knowledge and they would all sell the same products. There would be plenty of buyers and sellers in this market, and demand would help set prices evenly across the board. In order for a market to have perfect competition, there must be:.

The entry and exit in perfect market competition is not regulated, which means the government has no control over the players in any given industry. When it comes to their bottom lines, companies typically make just enough profit to stay in business. No one business is more profitable than the next. That's because the dynamics in the market cause them to operate on an equal playing field, thereby canceling out any possible edge one may have over another.

Since perfect competition is merely a theoretical concept, it is difficult to find a real-world example. But there are instances in the market that may appear to have a perfectly competitive environment. A flea market or farmer's market are two examples. Consider the stalls of four crafters or farmers in the market who sell the same products. This market environment is characterized by a small number of buyers and sellers. There may be little to differentiate between the products each crafter or farmer sells, as well as their prices, which are typically set evenly among them.

Imperfect competition occurs in a market when one of the conditions in a perfectly competitive market are left unmet. This type of market is very common.

In fact, every industry has some type of imperfect competition. This includes a marketplace with different products and services, prices that are not set by supply and demand, competition for market share, buyers who may not have complete information about products and prices, and high barriers to entry and exit.

Imperfect competition can be found in the following types of market structures: monopolies, oligopolies, monopolistic competition, monopsonies, and oligopsonies. In monopolies, there is only one dominant seller. That company offers a product to the market that has no substitute. Monopolies have high barriers to entry, a single seller which is a price maker.

That means the firm sets the price at which its product will be sold regardless of supply or demand. Econometrica 33 3 , — Arrow, K.
