State Bain's limit price theory.

Core Principles of Bain’s Limit Price Theory

The central idea behind limit pricing is that an established firm can discourage entry by setting its price low enough to make it unprofitable for potential entrants to operate. This doesn’t necessarily mean pricing at the competitive level, but rather at a level where the entrant, even with lower costs, would only earn normal profits or incur losses.

Mechanism of Limit Pricing

The theory operates on the following logic:

• Cost Structure Awareness: The incumbent firm estimates the potential entrant’s cost structure.
• Price Determination: The incumbent sets a price below what would maximize its short-run profits, but high enough to earn a satisfactory rate of return.
• Entry Deterrence: This lower price signals to potential entrants that the market is already served by a firm willing to sacrifice short-term gains to protect its market share.
• Credibility: The success of limit pricing hinges on the credibility of the incumbent’s commitment to maintaining the low price even if entry doesn’t occur.

Conditions for Successful Limit Pricing

Several conditions must be met for limit pricing to be effective:

• Significant Barriers to Entry: While not absolute, barriers must be substantial enough to make entry costly and risky.
• Accurate Cost Estimation: The incumbent must accurately estimate the potential entrant’s costs.
• Sufficient Market Power: The incumbent must have a significant market share to influence market prices.
• Stable Demand: Predictable demand allows for more accurate cost estimations and price setting.
• Low Elasticity of Demand: A less elastic demand curve allows the firm to maintain sales volume even with lower prices.

Limitations and Criticisms

Bain’s theory has faced criticism:

• Difficulty in Cost Estimation: Accurately estimating a potential entrant’s costs is challenging.
• Credibility Problem: Maintaining a low price indefinitely can be costly, and the incumbent may be tempted to raise prices once the threat of entry subsides.
• Predatory Pricing Concerns: Limit pricing can be difficult to distinguish from predatory pricing, which is illegal in many jurisdictions.
• Dynamic Markets: In rapidly changing markets, cost structures and demand patterns can shift quickly, rendering limit pricing ineffective.

Real-World Application

While direct evidence is difficult to obtain, the airline industry provides a potential example. Established airlines often engage in price wars on routes where new airlines are considering entry, potentially acting as a form of limit pricing. Similarly, in the telecom sector, dominant players sometimes offer promotional pricing to discourage new entrants.
