Potential competition refers to the influence exerted by the possibility of new entrants on the behavior of current market players. It plays a critical role in maintaining competitive markets, even when there are few firms currently in the market. This article delves into the historical context, theories, types, and significance of potential competition.
Historical Context
The concept of potential competition has been integral to economic thought for decades, particularly in the study of monopolies and market structures. The idea was formalized in the 20th century, particularly through the development of the theory of contestable markets by economists such as William Baumol, John Panzar, and Robert Willig in the 1980s.
The Theory of Contestable Markets
Key Principles
The theory of contestable markets asserts that the threat of potential entrants can lead to competitive outcomes similar to those in markets with many actual competitors. The main conditions for a market to be considered contestable are:
- Freedom of Entry and Exit: No significant barriers to entering or exiting the market.
- No Sunk Costs: Costs that cannot be recovered once incurred, influencing firms’ willingness to enter or exit.
Application
When these conditions hold, even a monopolistic firm must behave competitively to avoid the risk of new entrants capturing market share. This dynamic influences pricing, quality, and innovation within the industry.
Types and Categories of Potential Competition
- Direct Potential Competition: Arises from firms in related or adjacent industries looking to expand into a new market.
- Indirect Potential Competition: Emerges from advancements in technology or changes in consumer preferences that can facilitate new entrants.
- Latent Potential Competition: Potential competitors that are currently dormant but could enter the market with minimal costs.
Key Events and Historical Developments
- 1982: Publication of “Contestable Markets and the Theory of Industry Structure” by Baumol, Panzar, and Willig, marking a significant contribution to the understanding of potential competition.
- 1984: The US Department of Justice’s antitrust guidelines acknowledge potential competition as a key consideration in merger reviews.
Mathematical Models and Analysis
Basic Model
Consider a market where potential entrants evaluate their potential profits (\( \Pi \)) against entry costs (\( C \)):
Where:
- \( P \) is the price level that would be achieved post-entry.
- \( Q \) is the quantity expected to be sold.

Importance and Applicability
Economic Regulation
Potential competition serves as a regulatory tool, ensuring markets remain efficient and competitive. Regulators assess potential competition when evaluating mergers, acquisitions, and antitrust cases.
Business Strategy
Firms consider potential competition in strategic planning, often making preemptive moves such as lowering prices, enhancing quality, or innovating to deter new entrants.
Examples and Considerations
Examples
- Telecommunications: Potential competition from new technologies like VoIP affected traditional phone service providers.
- Retail: Potential competition from e-commerce platforms has compelled brick-and-mortar stores to innovate.
Considerations
- Entry Barriers: Factors like high capital requirements, regulatory hurdles, and brand loyalty can impact the extent of potential competition.
- Market Dynamics: Rapidly evolving industries may face more significant potential competition than stable markets.
Related Terms
- Monopoly: A market structure with a single firm dominating the market.
- Oligopoly: A market structure with a few firms, which may be influenced by potential competition.
- Barriers to Entry: Obstacles that can prevent new firms from entering the market.
Comparisons
- Actual vs. Potential Competition: Actual competition involves existing competitors, while potential competition involves the threat of new entrants.
- Static vs. Dynamic Competition: Static focuses on current market players, while dynamic involves potential entrants and future market changes.
Interesting Facts
- The concept of potential competition has influenced major antitrust decisions, such as the breakup of AT&T in 1984.
Inspirational Stories
- Amazon’s Rise: Jeff Bezos anticipated potential competition from traditional retailers and continually innovated to stay ahead, transforming Amazon into a market leader.

Summary
Potential competition plays a pivotal role in maintaining market discipline, influencing the behavior of incumbent firms, and fostering an environment of innovation and consumer welfare. The theory of contestable markets provides a foundational understanding of how the threat of entry can substitute for actual competition, thereby shaping market dynamics in significant ways. Understanding this concept helps in comprehending the broader economic landscape and the regulatory measures that ensure its robustness.
