What Is It?
Competition refers to rivalry among firms for customers, resources, and market share. It drives innovation, efficiency, and consumer welfare. Market structure—number of firms, barriers to entry, differentiation—determines competitive intensity.
Origin
Competition theory developed with classical economics (Smith, Ricardo) and evolved through industrial organization. Chamberlin and Robinson analyzed imperfect competition. Modern game theory (Nash, 1950s) formalized strategic interaction.
Why It Matters
Competitive dynamics determine profitability, innovation rates, and consumer surplus. Intense competition compresses margins; limited competition enables excess returns. Antitrust policy aims to preserve competition. Understanding competition is essential for company analysis.
Intermediate Level
Market Mechanics
Perfect competition (many firms, identical products) yields zero economic profit. Monopolistic competition allows differentiation. Oligopolies (few firms) enable strategic behavior. Monopolies (single firm) extract maximum surplus. Barriers to entry protect incumbents.
How It Behaves
Competition intensifies with low barriers, excess capacity, and slow growth. Price wars erupt in commoditized markets. Differentiation enables pricing power. Network effects create winner-take-all dynamics. Globalization increased competitive pressure.
Key Data to Watch
