Definition§
Perfect competition refers to a market structure characterized by numerous small firms or sellers and numerous small buyers, such that no single participant can influence the market price of a product. Key characteristics of perfect competition include:
- Large Number of Buyers and Sellers: There are so many participants that no individual buyer or seller can influence the market price.
- Homogeneous Products: The goods or services offered by all firms are identical and interchangeable.
- Perfect Information: All buyers and sellers have all relevant information needed to make informed decisions.
- Absence of Discrimination: No discrimination exists in selling and buying.
- Total Mobility: Resources can move freely in and out of the market.
- Free Entry and Exit: Firms can freely enter or exit the market without significant barriers.
Perfect competition is often considered a theoretical model because it rarely exists in practical scenarios. It serves as a benchmark for comparing actual market structures and understanding how different factors affect economic outcomes.
Examples§
- Agricultural Markets: Traditional markets for crops like wheat or corn might approximate perfect competition since numerous farmers sell identical products.
- Stock Markets: Some argue that stock exchanges can approach perfect competition due to the high number of buyers and sellers trading shares of the same company.
- Currency Exchange Markets: Various participants trade in foreign exchange without affecting the market price due to its vast size and liquidity.
