Background
Imperfect competition refers to market structures where individual firms have some control over the prices of their products rather than being price takers in a perfectly competitive market. This control arises due to various reasons like product differentiation, limited number of sellers, or particular market powers.
Historical Context
The concept of imperfect competition was significantly advanced by economists such as Edward Chamberlin and Joan Robinson in the early 20th century. Their work laid the groundwork for understanding markets that do not conform to the perfectly competitive model.
Definitions and Concepts
Imperfect competition is characterized by the presence of market power where sellers or buyers influence prices. It encompasses several types of market structures, including monopoly, monopsony, oligopoly, and monopolistic competition.
- Monopoly: A market with a single seller who determines the price due to lack of competition.
- Monopsony: A market with a single buyer wielding significant control over prices.
- Oligopoly: A market structure with a few sellers, creating mutual interdependence and significant control over pricing.
- Monopolistic Competition: Markets where firms sell differentiated products and free entry drives equilibrium profit to zero.
Major Analytical Frameworks
Classical Economics
Classical economists primarily focused on perfect competition and may have touched briefly on monopolistic practices but did not extensively explore imperfect competition.
Neoclassical Economics
Neoclassical economics provides various models to understand imperfect competition. It includes theories of market behavior and firm strategies in monopolies and oligopolies.
Keynesian Economics
Keynesian viewpoints may consider how imperfect competition can influence aggregate supply and demand, impacting macroeconomic stability and government policies.
Marxian Economics
In Marxian economics, imperfect competition could be seen as a distortion created by capital accumulation and market concentration, impacting labor and economic distribution.
Institutional Economics
Institutional economics would address how market imperfections arise due to regulatory environments, historical contexts, and organizational behaviors.
Behavioral Economics
Behavioral economists may study how irrational behaviors of firms or consumers contribute to imperfect competition and deviations from traditional economic models.
Post-Keynesian Economics
Post-Keynesian economics may encompass theories that explain how price-setting and market imperfections influence macroeconomic variables and policy implications.
Austrian Economics
Austrian economics critiques market interventions, emphasizing that imperfect competition results from natural market processes rather than failures needing correction.
Development Economics
Development economics looks at how market imperfections, such as monopolies and oligopolies, impact developing economies, influencing growth and inequality.
Monetarism
Monetarist perspectives might explore how imperfect competition affects money supply, inflation, and economic policies focusing on controlling market power to stabilize the economy.
Comparative Analysis
Comparative analysis within imperfect competition focuses on the differences in market structures, the extent of market power, pricing strategies, and welfare implications.
Case Studies
Case studies include examining industries like technology, telecommunications, and pharmaceuticals, where market power significantly affects pricing and competition.
