Quick Summary

In economics, competition refers to the dynamic interplay between firms within a market. This can range from perfect competition, where numerous small firms offer identical products and no single firm can influence prices, to monopolistic competition, where firms differentiate their products, allowing for some price control. Other market structures include oligopoly, with a few dominant firms, and monopoly, where a single supplier controls the market.12

Competition is influenced by factors such as the number of sellers, product differentiation, and the ease of new firms entering the market. Public policy, known as competition policy or antitrust policy, aims to prevent anti-competitive practices like price-fixing and the abuse of monopoly power to ensure fair markets, efficiency, and innovation. While free markets are often seen as efficient, critics argue that government intervention is sometimes necessary to address market failures and ensure fairness.134
