Consequences[ edit ] Competition can have both beneficial and detrimental effects. Many evolutionary biologists view inter-species and intra-species competition as the driving force of adaptationand ultimately of evolution. However, some biologists disagree, citing competition as a driving force only on a small scale, and citing the larger scale drivers of evolution to be abiotic factors termed 'Room to Roam'.
However, an economic analysis of the different firms or industries within an economy is simplified by first segregating them into different models based on the amount of competition within the industry. There are 4 basic market models: Because market competition among the last 3 categories is limited, these market models are often referred to as imperfect competition.
In a purely competitive marketthere are large numbers of firms producing a standardized product. Market prices are determined by consumer demand ; no supplier has any influence over the market price, and thus, the suppliers are often referred to as price takers.
The primary reason why there are many firms is because there is a low barrier of entry into the business. The best examples of a purely competitive market are agricultural products, such as corn, wheat, and soybeans.
Monopolistic competition is much like pure competition in that there are many suppliers and the barriers to entry are low. However, the suppliers try to achieve some price advantages by differentiating their products from other similar products.
Most consumer goods, such Pure competition health and beauty aids, fall into this category.
Suppliers try to differentiate their product as being better, so that they can justify higher prices or to increase market share. For instance, suppliers of toothpaste may try to convince the public that their product makes teeth whiter or helps to prevent cavities or periodontal disease.
An oligopoly is a market dominated by a few suppliers. Although supply and demand influences all markets, prices and output by an oligopoly are also based on strategic decisions: A high barrier to entry limits the number of suppliers that can compete in the market, so the oligopolistic firms have considerable influence over the market price of their product.
However, they must always consider the actions of the other firms in the market when changing prices, because they are certain to respond in a way to neutralize any changes, so that they can maintain their market share. Auto manufacturers are a good example of an oligopoly, because the fixed costs of automobile manufacturing are very high, thus limiting the number of firms that can enter into the market.
A pure monopoly has pricing power within the market.
There is only one supplier who has significant market power and determines the price of its product. A pure monopoly faces little competition because of high barriers to entry, such as high initial costs, or because the company has acquired significant market influence through network effects, such as Facebook, for instance.
One of the best examples of a pure monopoly is the production of operating systems by Microsoft. The 1st diagram shows consumer and producer surpluses under pure competition. An oligopoly or monopoly can increase profits Pe to Pm by reducing supplies Qe to Qmwhich increases prices.
This is reflected as an additional producer surpluswhich comes at the expense of lower consumer surplus for the buyers of the product. Additionally, some consumers will not buy the product because of the higher price, which is the area 1 in the diagram.
Additionally, some producer surplus is lost because there are fewer suppliers. The combined areas of losses equal the deadweight loss to the economy, the reduction in total surplus, that results from the oligopoly or monopoly restricting supply, so as to raise prices.Are you sick and tired of living with chronic pain?
