Background
Bertrand competition refers to a market structure in which two or more firms engage in price competition rather than competing on quantities. Named after the French mathematician and economist Joseph Bertrand, this type of competition involves firms strategically using prices as their primary competitive tool.
Historical Context
Bertrand competition was first introduced by Joseph Bertrand in 1883 as a critique of the Cournot model. Bertrand argued that when firms compete on price rather than quantity, even a duopoly can result in outcomes that are similar to perfect competition.
Definitions and Concepts
Definition
Bertrand Competition: A model of competition where firms set prices simultaneously, with the price being the primary strategic variable. If products are perfect substitutes, Bertrand competition leads to an outcome where price equals marginal cost, resulting in an efficient market equilibrium even with a limited number of firms.
Key Concepts
- Perfect Substitutes: Products that are viewed as identical in the eyes of consumers.
- Nash Equilibrium: A situation in which no firm can benefit by changing its price strategy while other firms keep their strategies unchanged.
- Marginal Cost: The cost of producing one additional unit of a product.
Major Analytical Frameworks
Classical Economics
Classical economics does not explicitly focus on Bertrand competition but does lay the groundwork by emphasizing the role of competition and prices in driving market efficiency.
Neoclassical Economics
Neoclassical economists build on Bertrand’s ideas, exploring the implications of price competition for market outcomes and firm behavior.
Keynesian Economic
Keynesians may integrate Bertrand competition into broader analyses of market imperfections and economic fluctuations.
Marxian Economics
Marxian economists might critique Bertrand competition for ignoring the complexities of capitalist markets and the power dynamics between firms.
Institutional Economics
Institutional economists focus on how contractual relationships, regulatory environments, and other institutional factors influence outcomes in Bertrand competitions.
Behavioral Economics
Behavioral economists study how psychological factors and cognitive biases affect pricing strategies and consumer response in markets characterized by Bertrand competition.
Post-Keynesian Economics
Post-Keynesians critique neoclassical assumptions, including those in Bertrand models, advocating for more realistic representations of market competition.
Austrian Economics
Austrian economists might argue against the static nature of Bertrand competition, emphasizing dynamic entrepreneurial discovery and innovation.
Development Economics
In the context of development, Bertrand competition could offer insights into price behavior in emerging markets and how competition influences market development.
Monetarism
While primarily concerned with monetary policy, monetarists might analyze how changes in money supply and interest rates affect price competition in markets.
Comparative Analysis
Bertrand competition differs from Cournot competition, where firms compete on quantities rather than prices. In Cournot models, equilibrium is determined by the quantity each firm chooses to produce. In contrast, Bertrand equilibrium is price-based and can lead to lower prices and greater economic efficiency in markets for perfect substitutes.
Case Studies
Real-world examples of Bertrand competition include industries with highly substitutable products, such as airlines, gasoline stations, and internet service providers. These case studies provide practical insights into how firms strategize their price settings in response to competitor actions and market conditions.

- Cournot Competition: A model in which firms compete on the quantity of output they will produce.
- Nash Equilibrium: A key concept in game theory where no participant can gain by unilaterally changing their strategy, given the strategies of all other participants.
- Price War: A competitive exchange among rival firms who lower prices to gain market share, which often drives prices below the industry’s equilibrium.
- Perfect Competition: A market structure characterized by a large number of small firms, identical products, and free entry and exit, leading to prices equaling marginal costs.
