Now equate with demand (Qd: at P=8, Qd=60; at P=6, Qd=80). Demand schedule: P = 10 – 0.05Q? Check: Q=80, P=6 yes; Q=60, P=8 yes. So demand: P=10 – 0.05Q. New supply: P=4 + 0.05Q? Let's derive: old supply P=2+0.05Q (since at Q=80, P=6). Then new supply P= (2+0.05Q)+2 = 4+0.05Q.
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. hkcee 2010 econ paper 2 q2
To help provide the exact answer and step-by-step math for your study session, could you provide the from your copy of the 2010 Paper 2 Question 2 ? Now equate with demand (Qd: at P=8, Qd=60; at P=6, Qd=80)
When handling a past paper scenario modeled after this question, use the following tactical approach: 1. Identify the Options List out all the paths the individual or firm can take. 2. Segregate Explicit and Implicit Value So demand: P=10 – 0
