Imperfect Competition Market Theory
In economics, imperfect competition is a market structure whereby the seller’s prices are not the same, and that there exist restrictions that prevent buyers and sellers from freely exchanging goods and services. While perfect competition is the most optimal market model, many markets operate with characteristics that make them imperfectly competitive. This article provides an overview of the main characteristics of imperfectly competitive markets, highlighting their differences from perfect markets.
In terms of structure, imperfectly competitive markets are characterized by the presence of non-uniform product offerings and/or prices. The non-uniform pricing can be made possible by the presence of product differentiation amongst competitive firms or by the fact that some firms possess market power due to the existence of entry or exiting restrictions. In addition, there can be a high degree of oligopoly with a limited number of firms controlling the overall market. In such markets, firms have the incentive and ability to influence market prices, making markets less competitive and distorting the efficient allocation of resources.
In terms of price, imperfectly competitive markets are typically characterized by non-uniform prices and price discrimination. For example, firms can price discriminate by charging different prices for the same product to different segments of the population or at different times of the day. Additionally, firms can practice “first-mover pricing” where they set a high initial price for a new product and then gradually decrease it as rivals enter the market. These pricing strategies allow firms to capture more of the market share and extract more value from consumers.
In terms of market quantity, imperfect competition can also lead to suboptimal outcomes. For example, firms may choose to restrict output in order to increase prices and make more profits. This can lead to lower levels of output, reduced consumer surplus, and more inefficient resource allocations. In addition, firms may encourage advertising and spend money on other marketing activities in order to differentiate themselves and better position their product offerings in the marketplace. This can also lead to higher levels of marketing expenditure and less efficient resource allocations.
Finally, imperfectly competitive markets can lead to a lack of market competition in terms of innovation and new product introductions. Firms that possess market power can limit the introduction of new products in order to maintain their control over the market. This can lead to stagnant innovation and a decline in overall industry growth.
In conclusion, imperfect competition can lead to several economically undesirable outcomes. Firms may employ pricing strategies that distort market prices and lead to inefficient resource allocations. They may also restrict output and limit innovation in order to maintain their market power. Thus, it is important for policymakers to ensure that all markets are fully competitive by identifying and eliminating any non-uniform prices, any entry and exit barriers, and any pricing strategies that distort the efficient allocation of resources.
