Starting a Business: Barriers to Entry

Students will explore why it can be difficult for new businesses to enter certain markets, and what factors create these 'barriers to entry'.

About This Topic

Barriers to entry are factors that make it challenging for new firms to compete in existing markets. Students examine high capital requirements for industries like car manufacturing or airlines, where billions in investment cover factories and R&D. Other barriers include economies of scale that lower costs for incumbents, patents protecting technology, strict government regulations, strong brand loyalty, and network effects in platforms like ride-hailing.

In the Firms and Market Structure unit, this topic explains why markets remain concentrated in oligopolies or monopolies. Students address key questions, such as why new companies struggle against established giants and how governments or technology influence entry. Singapore examples, like the telecom duopoly of Singtel and StarHub shaped by spectrum licensing, connect concepts to local realities and prepare students for analyzing market efficiency.

Active learning suits this topic well. Role-plays and case studies let students experience barriers firsthand, while group analysis of real firms builds critical evaluation skills. Collaborative sorting of barrier types clarifies distinctions, making abstract economic forces concrete and relevant to future business decisions.

Key Questions

1. Why is it hard for a new company to start making cars or airplanes?
2. What makes it difficult for new businesses to compete with big, established ones?
3. How do governments or technology sometimes make it easier or harder for new businesses to start?

Learning Objectives

• Classify specific industries based on their typical barriers to entry, such as high capital requirements or strong network effects.
• Analyze how economies of scale create a competitive advantage for established firms over new entrants.
• Evaluate the impact of government regulations and intellectual property rights on the ease of market entry for new businesses.
• Compare and contrast the barriers to entry in a monopoly versus an oligopoly market structure.

Before You Start

Market Structures: Perfect Competition, Monopoly, Oligopoly

Why: Students need a foundational understanding of different market structures to analyze how barriers to entry influence their prevalence and characteristics.

Basic Concepts of Supply and Demand

Why: Understanding how prices and quantities are determined in markets is essential for grasping how established firms use cost advantages or market power to deter new entrants.

Key Vocabulary

Barriers to Entry	Obstacles that make it difficult or impossible for new companies to enter a particular market and compete with existing firms.
Economies of Scale	The cost advantages that arise with increased output of a product, allowing established firms to produce at a lower average cost than new, smaller competitors.
Network Effects	A phenomenon where a product or service becomes more valuable as more people use it, creating a significant advantage for incumbent platforms.
Patents	Exclusive rights granted for an invention, preventing others from making, using, or selling it for a set period, thus creating a barrier to entry for competing technologies.
Capital Requirements	The amount of money, equipment, and other resources a business needs to start and operate, which can be a significant barrier in industries requiring large initial investments.

Watch Out for These Misconceptions

Common Misconception

Barriers to entry are mainly financial costs.

What to Teach Instead

Many barriers are non-financial, such as patents or brand loyalty. Sorting activities help students classify factors accurately, while discussions reveal how incumbents combine multiple barriers, fostering deeper understanding through peer examples.

Common Misconception

High barriers always benefit consumers.

What to Teach Instead

Barriers can lead to higher prices and less innovation in concentrated markets. Role-play debates expose trade-offs, as students defend positions with evidence, correcting views that overlook long-term inefficiencies.

Common Misconception

Technology removes all barriers to entry.

What to Teach Instead

Technology can create new barriers like network effects in apps. Case study analysis shows this duality, with groups charting pros and cons, helping students appreciate contextual impacts.

Active Learning Ideas

Barrier Sorting: Real-World Cards

Prepare cards listing factors like patents, capital costs, and regulations. In small groups, students sort them into categories such as legal, economic, and strategic barriers, then justify choices with market examples. Discuss as a class to refine categorizations.

30 min·Small Groups

Market Entry Pitch: Airline Challenge

Pairs develop a pitch for a new low-cost airline in Singapore, identifying three barriers and strategies to overcome them. Present to class, who vote on feasibility based on economic criteria. Debrief on realistic hurdles.

45 min·Pairs

Case Study Debate: Telecom Entry

Provide Singtel case study excerpts. Small groups debate if government spectrum auctions create fair barriers or protect incumbents. Each side presents evidence, followed by whole-class vote and economic analysis.

50 min·Small Groups

Barrier Mapping: Local Markets

Individually, students map barriers in a chosen Singapore market like F&B or e-commerce using a template. Share in small groups, pooling insights to create a class barrier matrix.

Real-World Connections

• Aspiring ride-sharing companies face immense network effects from established players like Grab, which has built a large user base and driver network in Singapore.
• The pharmaceutical industry presents high capital requirements and patent barriers, as developing new drugs involves extensive research, clinical trials, and regulatory approval processes, exemplified by companies like Pfizer.

Assessment Ideas

Exit Ticket

Present students with three hypothetical industries (e.g., a local hawker stall, a new smartphone manufacturer, a national airline). Ask them to identify the primary barrier to entry for each and briefly explain why.

Discussion Prompt

Facilitate a class discussion using the prompt: 'Imagine you want to start a new coffee shop in a neighborhood dominated by a large chain like Starbucks. What specific barriers would you face, and how might you try to overcome them?'

Quick Check

Provide students with a list of terms (e.g., economies of scale, patent, brand loyalty, high startup costs). Ask them to match each term to a brief description of how it acts as a barrier to entry in a specific industry, like car manufacturing.

Frequently Asked Questions

What are the main types of barriers to entry in Economics?

Key types include structural barriers like economies of scale and capital requirements, legal barriers such as patents and regulations, and strategic barriers like brand loyalty and predatory pricing. In Singapore, telecom licensing exemplifies legal barriers. Students benefit from examples across industries to see how these sustain market power and affect competition.

How do barriers to entry apply to Singapore markets?

Singapore's airline market faces high capital and regulatory barriers via Changi Airport slots, while banking has capital and trust barriers. Telecom duopoly persists due to spectrum scarcity. Analyzing local cases helps students link theory to policy impacts on innovation and consumer choice.

How can governments influence barriers to entry?

Governments raise barriers through regulations like safety standards in aviation or lower them via subsidies for startups. Singapore's pro-business policies, such as grants, ease entry in tech. Discussions on policy trade-offs teach students to evaluate efficiency versus consumer protection.

How can active learning help students understand barriers to entry?

Active methods like role-playing new entrants against incumbents make barriers tangible, as students negotiate hurdles in simulations. Group case studies on Singapore firms build analytical skills, while debates clarify nuances. These approaches shift passive recall to critical application, improving retention and real-world relevance for JC students.
