The Intricacies of Imperfect Competition
Imperfect competition prevails in markets that deviate from the stringent principles of neoclassical perfect competition. Here, businesses offer diverse products and services, determine their own prices, compete for market share, and benefit from barriers to entry and exit.
Key Points to Grasp
- Definition: Imperfect competition signifies any economic market deviating from the ideal assumptions of perfect competition.
- Market Behaviors: Companies set bespoke prices for varied products and services, fiercely vying for market share, with common protection through entry and exit barriers.
- Types: Common structures within imperfect competition include monopolies, oligopolies, monopolistic competition, monopsonies, and oligopsonies.
- Real-World Context: Economists acknowledge that virtually all real markets fail to meet perfect competition terms but differ on the impact extent.
Distinguishing Imperfect from Perfect Competition
In perfect competition, it is theoretical constructs in microeconomics used to clearly and precisely define consumer and producer behavior, supply, demand, and pricing within a mathematically simple framework. Often, in welfare economics and public policy, perfect competition serves as a yardstick to gauge the efficiency and functionality of actual markets.
Conditions for perfect competition include:
- Homogeneous Products: Companies offer identical products with no differentiation.
- Numerous Market Participants: The presence of many buyers and sellers prevents a single entity from impacting prices.
- Perfect Information: All market actors have comprehensive knowledge of market conditions, preferences, and technologies, past, present, and future.
- Zero Transaction Costs: All transactions occur without incurring any costs.
- Cost-Free Market Entry and Exit: Companies can enter or exit markets without any financial burdens.
Very few actual markets meet these conditions. Exceptions might include certain street vendors or farmer’s markets. The more a market diverges from these criteria, the more imperfect competition it entails. This difference results in firms gaining competitive advantages, leading to higher profits, sometimes at customer expense.
Historical Context of Imperfect Competition
The concepts underpinning models of perfect competition and monopoly findings were crystallized by French mathematician Augustin Cournot in his 1838 landmark work, Researches Into the Mathematical Principles of the Theory of Wealth. Later, these ideas were championed by Swiss economist Leon Walras.
Preceding Walras and Cournot, modeling economic relations and deriving reliable formulations posed significant challenges to mathematicians. The newly minted perfect competition model streamlined economic competition into a static, predictive baseline, free from real-world complexities such as market imperfections, entry barriers, and monopolies. This model gained traction particularly in England, pushing any deviations into problematic territories.
19th and 20th-century microeconomists mathematically advocated that perfect competition achieves maximal economic efficiency and social welfare. Notably, William Stanley Jevons argued the efficacy of competition increases devoid of price discrimination and in industries with either numerous sellers or fewer buyers. This ushered in the Cambridge tradition of economic thought, identifying real and theoretical market distortions, leading to terms like oligopoly and monopsony.
Limitations and Paradigms of Imperfect Competition
Despite meaningful contributions, the Cambridge school’s unwavering allegiance to a static, calculable economic science incurred flaws. Ironically, achieving a perfectly competitive market suggests eliminating active competition.
In such a market, all vendors would sell indistinguishable goods at identical prices to homogenous consumers well-versed with market details. This setup eradicates scope for advertising, product variation, innovation, or branding.
True perfect competition remains an unattainable target. The model sidelines critical elements like the allocation of physical capital, entrepreneurial dynamism, and fluctuating resource availability. More adaptable theories like Mises’ evenly rotating economy coexist, yet the foundational principal graphs and equations originating from the Cambridge tradition continue to pervade most introductory economics textbooks.
