Background
Market power refers to the capability of a firm or consumer to manipulate or influence the price of goods or services in a market. This power emerges from being a significant player relative to others in the market.
Historical Context
The concept of market power has been analyzed extensively since the emergence of classical economic theory, where economists began studying how market structures affect economic outcomes. Over time, more sophisticated analyses have considered various determinants of market power beyond sheer size.
Definitions and Concepts
Market Power: The ability of an economic agent, such as a firm or consumer, to influence the equilibrium price of a good or service in a market.
Equilibrium Price: The market price at which the quantity of goods supplied equals the quantity of goods demanded.
Major Analytical Frameworks
Classical Economics
Early views considered market power primarily through the lens of natural monopolies and market size.
Neoclassical Economics
Within this framework, market power is often analyzed through the competitive landscape of the market. One key metric used is the *N-firm concentration ratio, denoting the total market share of the top N firms in the industry.
Keynesian Economics
Here, less emphasis is placed on individual firm behavior and more on aggregate demand and market dynamics.
Marxian Economics
Focuses on how market power can lead to exploitation and uneven distributions of wealth within a capitalist system.
Institutional Economics
Emphasizes the role of institutional rules and regulatory bodies in either curbing or encouraging market power among firms.
Behavioral Economics
Explores how psychological factors and bounded rationality of consumers and firms impact market power and price-setting behavior.
Post-Keynesian Economics
Draws attention to real-world complications, such as imperfect competition and the endogenous creation of money impacting market power relations.
Austrian Economics
Critiques concepts of market power by emphasizing dynamic competition and the temporarily advantaged position of innovators and market players.
Development Economics
Considers how market power imbalances can hinder or facilitate economic development and affects poverty and inequity levels.
Monetarism
Focuses more on the role of money supply and central banking policies rather than individual market power dynamics.
Comparative Analysis
Comparing different economic schools of thought reveals various determinants of market power while realizing its implications for welfare economics, competitive limitations, and regulatory needs.
Case Studies

- Microsoft in the late 20th century for its dominant market share in software.
- Amazon’s significant influence on e-commerce pricing.
