imperfect competition
Quick Summary
Imperfect competition describes market situations where sellers offer inhomogeneous products, and their numbers are few enough that each can influence the market. This contrasts with perfect competition, where numerous sellers offer identical products and no single seller can influence the market.12
Key forms of imperfect competition include:
* Monopolistic Competition: Many sellers offer similar but not identical products. Competition focuses on product differentiation and advertising rather than solely on price.34
* Oligopoly: A few producers dominate the market. Each producer's actions significantly impact the others, leading to competition through advertising and product features rather than price cuts.5
The theory of monopolistic competition, developed by Edward Hastings Chamberlin and Joan Robinson, analyzes market phenomena like product differentiation and oligopoly.4
