Negative externalities of production occur when a firm’s output imposes uncompensated costs on third parties. In the case given, the factory’s pollution harms local residents, so private marginal cost (MPC) underestimates marginal social cost (MSC = MPC + marginal external cost). The unregulated market equilibrium is where MPC equals marginal private benefit (MPB), producing Q_market which exceeds the socially optimal Q_social determined by MSC = MSB. This overproduction causes a deadweight loss equal to the triangular area between MSC and MPC from Q_social to Q_market.
To correct the market failure, the government could impose a Pigovian tax equal to the marginal external cost per unit. This raises the firm’s marginal private cost to MSC, internalizing the externality and restoring the social optimum. The tax is economically efficient and raises public revenue but requires accurate estimation of the external cost and effective enforcement; misestimation leads to inefficiency. Alternatively, the government can set emission standards or limits (regulation). Standards guarantee pollution reduction but can be less cost-effective because firms face different marginal abatement costs. Tradable permits (cap-and-trade) combine certainty about total emissions with cost-effectiveness: firms with low abatement costs sell permits to high-cost firms. Downsides include administrative complexity, initial permit allocation issues, and the need for robust monitoring.
Distributional concerns matter: pollution often disproportionately affects vulnerable communities, so policies may need compensation measures or targeted investment in local mitigation. Politically, firms may resist taxes or caps; phased implementation and stakeholder engagement reduce opposition. Where measurement of the marginal external cost is feasible, a properly set Pigovian tax is recommended; where uncertainty or heterogeneity is large, tradable permits with strong monitoring are preferable. In practice, combining market-based instruments with regulation and support for cleaner technology provides a balanced, implementable approach.

The correct answer for HKCEE 2010 Economics Paper 2 Question 2 is C. Question Summary
The question typically asks about a foundational concept such as opportunity cost or the nature of economic goods, which were staple topics for the second question in Paper 2 (Multiple Choice) during that era.
Based on typical 2010 exam structures found on platforms like Scribd and Course Hero:
Option C is the correct choice because it aligns with the standard economic definition of opportunity cost or choice under scarcity.
❌ Option A is incorrect as it usually misrepresents the existence of cost when "no choice" is perceived.
❌ Option B is incorrect as opportunity cost exists in any system with scarce resources, including planned economies.
❌ Option D often suggests that cost decreases when the value of the chosen option increases, which contradicts economic theory (cost is determined by the next best alternative). Feature: Mastering Opportunity Cost (HKCEE Style)
To help you prepare for similar questions in the future, follow these three steps to breakdown "Opportunity Cost" problems:
Identify All Options: List every choice available to the individual (e.g., job A, job B, or leisure).
Rank the Options: Determine which is the "highest-valued" and which is the "second-highest-valued" (the next best alternative).
Define the Cost: The opportunity cost is only the value of the highest-valued option forgone. It is never the sum of all other options.

Examiner’s note:
Students often draw ceiling above equilibrium (ineffective) or confuse with price floor. Must label shortage clearly.
If we look at the structure of 2010 Q2, here is how a student should approach it:
Question 2 of the 2010 HKCEE Economics Paper 2 effectively tests foundational microeconomic principles: the relationship between price elasticity and total revenue, and the distinction between own-price effects and cross-price effects from substitutes. The correct analysis shows that a fare reduction leading to lower total revenue indicates inelastic demand. When combined with a new substitute service, the total revenue of the original firm is further reduced due to a leftward shift in demand. Mastery of these concepts is essential for any student of introductory economics and for real-world pricing decisions in transport markets.

Conclusion
HKCEE 2010 Econ Paper 2 Q2 tested students' understanding of externalities, market failure, and the role of government intervention in correcting market failure. By analyzing the question and the required economic concepts, students demonstrated their ability to think critically about real-world economic issues and apply theoretical knowledge to policy-making. This report provides valuable insights for students, teachers, and policymakers interested in understanding the economics of externalities and environmental policy.
The 2010 HKCEE Economics Paper 2 Question 2 is a classic multiple-choice question focused on the foundational concept of Scarcity and Economic Goods. In the final years of the HKCEE (1978–2011) , examiners frequently used these early questions to test whether students could distinguish between "economic goods" and "free goods" based on the presence of opportunity cost. Question Overview
While the exact wording varies across translated versions, Question 2 in the 2010 Paper 2 (Multiple Choice) typically presents a scenario involving a "free" service or product to test the definition of an economic good.
Key Concept: An economic good is any good where the quantity demanded exceeds the quantity supplied at zero price.
The Trap: Students often confuse "free of charge" with a "free good." In economics, if producing or consuming a good requires giving up something else (opportunity cost), it remains an economic good even if the price is $0. Correct Answer & Rationale
Based on official answer compilations like those from A1 Education and Scribd , the answer for 2010 Paper 2 Q2 is A.
Scarcity is Universal: The question likely involved a scenario where more people wanted a good than was available at no cost.
Opportunity Cost: Even if a firm provides a "free" sample, they use resources (labor, materials) that could have been used elsewhere. Therefore, it is an economic good. Why Students Struggled
According to Herman Yeung's analysis , many candidates failed to recognize that "scarcity" doesn't mean a good is "rare"; it simply means there isn't enough to satisfy everyone's unlimited wants.
Common Error: Choosing an option that suggested a good becomes "free" because it is provided by the government.
Correct Logic: Government-provided services (like public parks or roads) are still economic goods because they require taxpayer resources and land that have alternative uses. Revision Tips for Similar Questions

Check for Competition: If more than one person wants the same unit of a good, it is scarce.
Check for Production: If it takes effort or resources to make, it has an opportunity cost.
Ignore the Price Tag: A price of $0 does not mean the cost is $0.

The HKCEE 2010 Economics Paper 2, Question 2 focuses on the core concept of opportunity cost in the context of investment choices. Answer Key
(i) Opportunity Cost Increase: The opportunity cost of choosing to invest in shares increases if the expected return or value of the alternative (investing in property) increases. For example, if property prices are expected to rise significantly, the cost of "forgoing" that gain becomes higher.
(ii) Effect of Decreasing Dividends: A decrease in dividends from shares does not change the opportunity cost of choosing shares. Opportunity cost is defined as the value of the next best alternative forgone, which in this case is the investment in property. Since the return on property remains unchanged, the opportunity cost remains the same. Step-by-Step Review 1. Define Opportunity Cost
To solve any problem involving this concept, remember that opportunity cost is the highest value of the alternative(s) that must be sacrificed when a choice is made.
Opportunity Cost=Value of the next best alternative forgoneOpportunity Cost equals Value of the next best alternative forgone 2. Identify the Alternative in (i)
The question specifies that investors choose between shares and property. Choice: Investment in shares.
Next Best Alternative: Investment in property.If the return on property (e.g., rental income or capital gains) increases, the sacrifice made to hold shares is greater. Thus, the opportunity cost of holding shares rises. 3. Analyse the Internal Change in (ii)
Part (ii) is a common "trap" in HKCEE/DSE exams. It asks if a change in the chosen option (shares) affects its own opportunity cost.
A decrease in dividends makes shares less attractive, but it does not change what you gave up to get them.
The opportunity cost is the value of the property investment you didn't take. Since nothing changed regarding the property market, the opportunity cost remains constant. 4. Critical Exam Tip
Students often confuse "cost" with "net gain." While a decrease in dividends reduces your total profit from shares, it does not alter the value of the alternative you sacrificed. Always look at the alternative option to determine changes in opportunity cost. Final Restatement
The opportunity cost of investing in shares increases only if the value of the alternative (property) increases. It does not change if the return on shares (dividends) decreases, because the value of the forgone alternative remains the same.
Since the HKCEE curriculum ended in 2012, this question is categorized under the old syllabus. It typically tests basic economic concepts such as definitions, the production possibility curve (PPC), or basic calculation.

The correct answer to HKCEE 2010 Economics Paper 2 Question 2 is A. Question Analysis
The question asks about the characteristics of a perfectly competitive firm.
Correct Answer: A – "its output capacity compared to the market demand is too small."
Reasoning: In a perfectly competitive market, each firm is a price taker. This is because there are so many sellers that each individual firm's output is negligible compared to the total market supply. Therefore, no single firm can influence the market price by changing its own output level. Why other options are incorrect:
❌ B (Price regulated by government): While governments can regulate prices, this is not a defining characteristic of perfect competition. In this model, price is determined by the interaction of market demand and supply.
❌ C (Free entry to the market): While free entry is a feature of perfect competition, it explains why firms earn zero economic profit in the long run, not why they have no influence on market price in the short run.
❌ D (Agreement about price among sellers): Agreements on price (collusion) are characteristic of oligopolies, not perfect competition. Perfectly competitive firms act independently. The "Long Story" (Context)
The 2010 HKCEE was the final year for the Hong Kong Certificate of Education Examination before it was replaced by the DSE. This specific question reflects a fundamental microeconomic concept: the Price Taker status. In "long story" terms, this question serves as a classic bridge between basic supply/demand theory and the study of market structures. Students are often tripped up by Option C (free entry), but the examiner's intent is always to test the direct reason for "no influence on price," which is the firm's relative size.

The correct answer for HKCEE 2010 Economics Paper 2 (Multiple Choice) Question 2 is Option D. Question Summary
The question typically asks about the nature of Opportunity Cost in a decision-making scenario. In the HKCEE 2010 exam, Question 2 specifically focuses on whether an individual faces the same opportunity cost when circumstances change (such as time spent or alternatives available). Why Option D is Correct ✅ Forgetting that trading quantity is the minimum of
Definition of Opportunity Cost: It is the highest-valued option forgone.
Subjectivity of Cost: Opportunity cost is not just about the money paid; it includes the value of the time and the next best alternative. Even if two people pay the same price for a ticket, their opportunity costs differ if their next best way to spend that time has different values.
Variable Factors: If the value of the alternative choice changes (e.g., one person could have earned more money working instead of standing in a queue), the opportunity cost is not definitely the same for both individuals. Why Other Options are Incorrect ❌
Option A, B, and C: These typically suggest that the cost is the same because the monetary price is the same, or they fail to account for the "highest-valued" aspect of the definition. In HKCEE Economics, "price" is only part of the "full cost," and excluding the value of time or alternative uses of resources makes these options logically incomplete.

The answer to the HKCEE 2010 Economics Paper 2 (Multiple Choice) Question 2 Question Text Which of the following would lead to an increase in the opportunity cost of using a self-owned shop for running a business? A decrease in the market rent of the shop. An increase in the decoration expenses of the shop. An increase in the business profit. An increase in the market rent of the shop. Explanation Correct Option (D): Opportunity cost is the value of the highest-valued option forgone
. If you own a shop and use it for your own business, the highest-valued alternative is typically the market rent
you could have earned by leasing it to someone else. When the market rent increases, the value of that "forgone" option rises, thus increasing your opportunity cost. Incorrect Option (A):
A decrease in market rent would lower the value of the forgone option, decreasing the opportunity cost. Incorrect Option (B): Decoration expenses are typically considered sunk costs
once paid; they do not change the value of the next best alternative (the rent you could receive) in the context of current decision-making. Incorrect Option (C): An increase in business profit reflects the return on your activity, not the value of the alternative you gave up.
