The definition and types of entry barriers

Entry barriers consist of obstacles that make it difficult for new businesses to join a market and compete with existing ones.

Categories of entry barriers:

• State-created barriers - These arise from government actions or regulations that restrict new entrants.
• Firm-created barriers - These are strategies employed by existing businesses to deter potential competitors.
• Natural barriers - These occur due to inherent market or economic conditions that naturally favour larger or established firms.

State-created barriers to entry

Governments can impose barriers that limit market entry.

Patents

Patents provide legal protection for inventions, granting exclusive rights to produce or use a new product or technology for up to 20 years. This encourages firms to invest in research and development (R&D) by ensuring they can benefit from their innovations without immediate competition. For example, a pharmaceutical company might patent a new medicine, preventing others from copying it during the protected period.

Licenses

Licenses are official permissions granted by governments to a limited number of firms, restricting who can operate in certain sectors. They are used to allocate scarce resources, such as radio frequencies for broadcasters, or to ensure professional standards, like certifications for doctors or accountants. Professional bodies may limit licenses to maintain high standards and fees, which can give existing members some monopoly-like power.

Trade barriers

Trade barriers include measures like tariffs (taxes on imports), quotas (limits on import quantities), and other restrictions that reduce foreign competition. These protect local businesses and jobs but often result in higher prices for consumers.

Firm-created barriers to entry

Existing businesses can actively create barriers by using tactics that make it hard or unprofitable for new firms to enter the market.

Strategic deterrence tactics

• Excess capacity - Firms keep extra production facilities ready to increase output quickly and lower prices if new competitors appear.
• Heavy advertising - Investing in widespread promotion builds strong brand loyalty, which new entrants struggle to overcome without similar spending.
• Product differentiation - Offering a wide range of product variations fills market gaps, leaving little room for competitors to introduce similar items.
• Low pricing - Setting prices just above average costs discourages new firms by signalling slim profit opportunities.

Acquisition strategies

Large firms often buy out smaller competitors or promising startups to eliminate threats and consolidate their market share. Examples include a major tech firm purchasing smaller app developers, a dominant online search provider buying video-sharing platforms, or a leading social media company acquiring rival messaging services. Such actions might be seen as misuse of market power and could face legal scrutiny.

Natural barriers to entry

Natural barriers emerge from economic or market conditions without government or firm intervention.

Economies of scale

Economies of scale occur when average costs per unit fall as a firm increases its size and output in the long run, allowing adjustments to all production factors. High initial setup costs, such as for building transport networks or power grids, make it hard for small firms to compete.

Larger firms benefit from:

• Buying materials in bulk at discounted rates.
• Securing loans on better terms due to lower perceived risk.
• Using large, efficient equipment that smaller operations cannot afford.
• Spreading fixed costs, like administration, over more units produced.

Natural monopoly

A natural monopoly exists when market demand supports only one profitable firm, as splitting the market would lead to losses for multiple operators. The single firm achieves lower costs through economies of scale. Governments often regulate these monopolies, setting prices to prevent excessive profits while ensuring service provision.

Exclusive resource ownership

Controlling a unique or essential resource naturally blocks competitors from entering the market. For instance, if a company owns the only viable land access to a popular natural site, it can exclusively develop and control tourism activities there.
