Mastering core economic concepts is vital for excelling in the Hong Kong public examinations. The focuses on foundational microeconomic principles, serving as a critical checkpoint for both historic Hong Kong Certificate of Education Examination (HKCEE) candidates and current HKDSE Economics students.
: A resource facing scarcity requires a human sacrifice to obtain, making it an economic good . If it is not scarce, it is a free good . 2. The Nuances of Opportunity Cost
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.
(a) With the aid of a diagram, explain the effects of a price ceiling set at $4 on: (i) market quantity, (ii) consumer surplus, (iii) producer surplus, and (iv) total social surplus. Is there a deadweight loss? hkcee 2010 econ paper 2 q2
Even though the Hong Kong Examinations and Assessment Authority (HKEAA) replaced the HKCEE with the HKDSE exam system, this specific past paper question remains highly relevant. It serves as an essential teaching resource for students looking to secure a high grade in secondary-level economics. Core Economic Principles Behind Q2
To provide a concrete example, let's create a sample Question 2 based on typical HKCEE 2010 Economics Paper 2 MCQs.
Because it is scarce, people must make choices, which leads to the existence of Opportunity Cost . Common Question Structure Mastering core economic concepts is vital for excelling
This question focuses on —specifically, the effects of a price ceiling (maximum price) and a specific tax. Even though the HKCEE has been replaced by the HKDSE, the economic reasoning tested in Q2 remains fundamental for understanding real-world policies like rent control, minimum wage, and commodity taxes.
| Question Part | Model Answer | Marking Notes & Exam Tips | | :--- | :--- | :--- | | | A normal good is a good whose demand increases when consumers' income rises. An inferior good is a good whose demand decreases when consumers' income rises. | Award 1 mark for each correct definition. Use precise language. | | Q2(b) | Income elasticity of demand (YED) measures the responsiveness of quantity demanded to a change in income.
Note: If you have the exact wording of the question, I can refine the analysis further. This reconstruction is based on standard examiner reports and typical HKCEE format. If it is not scarce, it is a free good
The HKCEE examiner’s report highlighted frequent mistakes:
Determine if the question is asking for a definition or the application of a concept to a real-world scenario.
