1. Interpreting Demand and Supply Diagrams | 解读供需图
Diagram-based questions are very common, often asking you to illustrate and explain a change in market equilibrium. You must draw clearly labelled axes, curves and equilibrium points.
图表题非常常见，通常要求你画出并解释市场均衡的变化。你必须绘制标注清晰的坐标轴、曲线和均衡点。
Example: ‘Using a demand and supply diagram, show the effect of a successful advertising campaign for a smartphone brand.’
典型例题： “使用供需图，展示某智能手机品牌成功广告宣传的效果。”
Step 1: Draw the axes. Label the vertical axis ‘Price (£)’ and the horizontal axis ‘Quantity (units)’.
步骤1：画出坐标轴。在纵轴标出“价格（英镑）”，横轴标出“数量（单位）”。
Step 2: Sketch an initial downward-sloping demand curve (D1) and an upward-sloping supply curve (S). Mark the original equilibrium point where they intersect (P1, Q1).
步骤2：画出初始的向下倾斜的需求曲线（D1）和向上倾斜的供给曲线（S）。在两者交点标出初始均衡点（P1, Q1）。
Step 3: Because advertising increases the popularity of the product, demand shifts to the right from D1 to D2. Draw the new demand curve clearly to the right of the original.
步骤3：由于广告提升了产品的知名度，需求从 D1 右移至 D2。将新需求曲线清晰地画在原曲线的右侧。
Step 4: Mark the new equilibrium where D2 meets S. Label the higher equilibrium price P2 and larger equilibrium quantity Q2.
步骤4：在 D2 与 S 的交点标出新均衡。标出更高的均衡价格 P2 和更大的均衡数量 Q2。
Step 5: Explain that the outward shift in demand leads to a rise in both equilibrium price and quantity, showing the market outcome of the campaign.
步骤5：解释需求向外移动导致均衡价格和数量双双上升，从而展示广告宣传的市场结果。
2. Calculating Price Elasticity of Demand (PED) | 计算需求价格弹性（PED）
Calculation questions test your ability to measure responsiveness. Always show your working, use the correct formula and interpret the numerical result.
计算题考察你衡量反应程度的能力。务必展示计算过程，使用正确的公式，并解释数字结果。
Example: ‘A cinema increases ticket price from £8 to £10. Daily ticket sales fall from 500 to 400. Calculate the PED and state whether demand is elastic or inelastic.’
典型例题： “一家电影院将票价从 £8 提高到 £10。每日售票量从 500 张降至 400 张。计算 PED 并说明需求是弹性的还是缺乏弹性的。”
Step 1: Recall the PED formula. Use the midpoint method if data is not percentage changes.
步骤1：回忆 PED 公式。如果给出的是绝对数值，需使用中点法。
PED = (%Δ quantity demanded) / (%Δ price)
PED = (ΔQd / Qdₐᵥ) ÷ (ΔP / Pₐᵥ)
Step 2: Calculate change in quantity: Qd falls by 100. Average quantity = (500+400)/2 = 450. So %ΔQd = (100/450) × 100 = 22.22%.
步骤2：计算数量变化：需求量减少 100。平均数量 = (500+400)/2 = 450。因此数量变化百分比 = (100/450) × 100 = 22.22%。
Step 3: Calculate change in price: price rises by £2. Average price = (8+10)/2 = £9. So %ΔP = (2/9) × 100 = 22.22%.
步骤3：计算价格变化：价格上涨 £2。平均价格 = (8+10)/2 = £9。因此价格变化百分比 = (2/9) × 100 = 22.22%。
Step 4: PED = 22.22% / 22.22% = 1.0. Ignore the negative sign when stating elasticity.
步骤4：PED = 22.22% / 22.22% = 1.0。在表述弹性时忽略负号。
Step 5: Since PED = 1, demand is unit elastic. Total revenue remains unchanged because the proportional change in price equals the proportional change in quantity demanded.
步骤5：由于 PED = 1，需求是单位弹性。总收入不变，因为价格变动的比例与需求量变动的比例相等。
Examiner tip: always state whether demand is elastic, inelastic or unit elastic.
评卷提示：一定要说明需求是弹性的、缺乏弹性的还是单位弹性的。
3. Impact of Indirect Taxes on Markets | 间接税对市场的影响
Tax diagram questions require you to show the tax wedge, new prices and the division of tax burden between consumers and producers.
税收图表题要求你展示税收楔子、新价格以及消费者与生产者之间的税负分担。
Example: ‘Draw a diagram to show the effect of a specific tax of £3 per unit on fizzy drinks. Explain who bears the larger burden.’
典型例题： “画图展示每单位碳酸饮料征收 £3 从量税的影响，并解释谁承担更大的税负。”
Step 1: Draw initial demand (D) and supply (S). Mark equilibrium price P and quantity Q.
步骤1：画出初始需求（D）和供给（S）。标出均衡价格 P 和均衡数量 Q。
Step 2: The tax shifts the supply curve vertically upwards by the amount of the tax. Draw new supply curve S+tax, parallel to S.
步骤2：税收使供给曲线垂直向上移动等量的税额。画出与 S 平行的新供给曲线 S+tax。
Step 3: Identify the new equilibrium at the intersection of D and S+tax. The price paid by consumers rises to Pc; the price received by producers falls to Pp. Quantity falls to Q1.
步骤3：在 D 与 S+tax 的交点确定新均衡。消费者支付的价格升至 Pc，生产者实际收到的价格降至 Pp。数量降至 Q1。
Step 4: The vertical distance between Pc and Pp equals the tax per unit (£3). Consumer burden = Pc – P; producer burden = P – Pp.
步骤4：Pc 与 Pp 之间的垂直距离等于每单位税额（£3）。消费者负担 = Pc – P；生产者负担 = P – Pp。
Step 5: If demand is relatively inelastic, consumers bear a larger share. Explain that because demand for fizzy drinks is often price inelastic for some consumers, the consumer burden is larger.
步骤5：如果需求相对缺乏弹性，消费者承担更大份额。解释由于部分消费者对碳酸饮料的需求价格往往缺乏弹性，因此消费者负担更重。
4. Understanding Market Failure and Externalities | 理解市场失灵与外部性
Questions about negative externalities ask you to explain why the free market fails to allocate resources efficiently and how this can be shown on a diagram.
关于负外部性的问题要求你解释自由市场为何未能有效配置资源，以及如何用图表展示。
Example: ‘Explain why air pollution from a factory is a negative production externality and how it leads to market failure.’
典型例题： “解释工厂的空气污染为何是负生产外部性，以及它如何导致市场失灵。”
Step 1: Define negative production externality: a cost suffered by a third party as a result of production, where no compensation is paid.
步骤1：定义负生产外部性：生产过程中第三方承担的成本，且未得到补偿。
Step 2: Draw two curves: marginal private cost (MPC) and marginal social cost (MSC). MSC lies above MPC by the value of the external cost (e.g. health damage).
步骤2：画出两条曲线：边际私人成本（MPC）和边际社会成本（MSC）。MSC 位于 MPC 上方，高出部分为外部成本（如健康损害）。
Step 3: The demand curve equals marginal social benefit (MSB). The free market produces where MPC = MSB, giving output Qm. The socially efficient output is where MSC = MSB, giving Qs.
步骤3：需求曲线等同于边际社会收益（MSB）。自由市场在 MPC = MSB 处生产，产量为 Qm。社会最优产量在 MSC = MSB 处，为 Qs。
Step 4: Because Qm > Qs, there is over-production and over-consumption. This creates a welfare loss triangle between Qs and Qm, where MSC > MSB.
步骤4：由于 Qm > Qs，导致过度生产与过度消费。这会在 Qs 至 Qm 之间产生福利损失三角，此时 MSC > MSB。
Step 5: The market fails because it does not take into account the external costs. Resources are misallocated, and society is worse off.
步骤5：市场失灵是因为它未考虑到外部成本。资源配置不当，社会整体福利下降。
5. Government Intervention: Subsidies | 政府干预：补贴
Subsidy questions test your ability to show a shift in supply, new equilibrium, and the distribution of benefits.
补贴题测试你展示供给移动、新均衡和利益分配的能力。
Example: ‘The government gives a £2 per unit subsidy to bus operators. Show the effect on the market for bus journeys and explain who benefits.’
典型例题： “政府给予公车运营者每趟 £2 的补贴。展示对公车服务市场的影响，并解释谁从中受益。”
Step 1: Draw the original demand (D) and supply (S1). Initial equilibrium at P1, Q1.
步骤1：画出原始需求（D）和供给（S1）。初始均衡点为 P1, Q1。
Step 2: A subsidy reduces the cost of production, so supply shifts downwards/rightwards by the subsidy amount. Draw new supply curve S2 below S1.
步骤2：补贴降低了生产成本，因此供给曲线向下/向右移动补贴额的距离。画出位于 S1 下方的新供给曲线 S2。
Step 3: New equilibrium at intersection of D and S2. Price to consumers falls to Pc, price received by producers rises to Pp, where Pp = Pc + subsidy. Quantity increases to Q2.
步骤3：D 与 S2 相交形成新均衡。消费者价格降至 Pc，生产者实收价格升至 Pp，且 Pp = Pc + 补贴额。数量增至 Q2。
Step 4: Consumer benefit = P1 – Pc; producer benefit = Pp – P1. Identify that both groups gain from lower consumer prices and higher producer revenue.
步骤4：消费者获益 = P1 – Pc；生产者获益 = Pp – P1。指出双方分别因消费者价格更低和生产者收入更高而获益。
Step 5: Explain that the subsidy increases consumption of bus journeys, which might reduce congestion and pollution, achieving other policy goals.
步骤5：解释补贴增加了公车服务消费，这可能减少拥堵与污染，从而实现其他政策目标。
6. Production Possibility Frontier (PPF) Shifts | 生产可能性边界（PPF）的移动
PPF questions assess your understanding of opportunity cost and economic growth. A typical question asks you to illustrate how a change in resources or technology affects a country’s productive capacity.
PPF 问题考察你对机会成本与经济增长的理解。典型问题要求你展示资源或技术变化如何影响一个国家的生产能力。
Example: ‘Draw a PPF showing an economy producing consumer goods and capital goods. Show the effect of an advance in capital goods technology.’
典型例题： “画一条 PPF，展示生产消费品与资本品的经济。展示资本品技术进步的影响。”
Step 1: Draw two axes: ‘Consumer goods’ on one axis and ‘Capital goods’ on the other. Sketch a concave (bowed-out) PPF curve, labelled PPF1.
步骤1：画出两条轴：一轴为“消费品”，另一轴为“资本品”。画一条凹向原点的 PPF 曲线，标注为 PPF1。
Step 2: Mark an initial point A on PPF1 where the economy is productively efficient.
步骤2：在 PPF1 上标出初始点 A，表示经济处于生产有效率状态。
Step 3: An advance in capital goods technology improves the ability to produce capital goods but may not directly affect consumer goods production. The PPF pivots outward along the capital goods axis. Draw PPF2.
步骤3：资本品技术进步提高了资本品的生产能力，但可能不直接影响消费品生产。PPF 沿资本品轴向外旋转。画出 PPF2。
Step 4: Show that the maximum output of capital goods increases, while the maximum output of consumer goods stays the same unless technology in consumer goods also improves.
步骤4：展示资本品最大产量增加，而消费品最大产量保持不变，除非消费品技术也进步了。
Step 5: The economy can now produce more capital goods, which leads to future economic growth. Explain that this outward shift represents an increase in productive potential.
步骤5：该经济现在可以生产更多资本品，这会带来未来的经济增长。解释这种向外移动代表了生产潜力的增加。
7. Measuring Inflation using CPI | 用消费者价格指数（CPI）衡量通货膨胀
Calculation questions using the Consumer Price Index (CPI) require you to compute the inflation rate and interpret the result.
使用消费者价格指数（CPI）的计算题要求你计算通货膨胀率并解释结果。
Example: ‘The CPI in January 2022 was 115. In January 2023 it was 121.9. Calculate the annual inflation rate.’
典型例题： “2022 年 1 月 CPI 为 115，2023 年 1 月为 121.9。计算年通货膨胀率。”
Step 1: Use the percentage change formula.
步骤1：使用百分比变化公式。
Inflation rate = [(CPI₂ – CPI₁) / CPI₁] × 100
Step 2: Subtract the earlier CPI from the later CPI: 121.9 – 115 = 6.9.
步骤2：用后一年 CPI 减去前一年 CPI：121.9 – 115 = 6.9。
Step 3: Divide the difference by the original CPI: 6.9 / 115 = 0.06.
步骤3：将差值除以前一年 CPI：6.9 / 115 = 0.06。
Step 4: Multiply by 100 to obtain the percentage: 0.06 × 100 = 6%. The annual inflation rate is 6%.
步骤4：乘以 100 得到百分比：0.06 × 100 = 6%。年通货膨胀率为 6%。
Step 5: Explain that inflation means the general level of prices is rising. A 6% rate means the average basket of goods now costs 6% more than a year ago, reducing purchasing power.
步骤5：解释通货膨胀意味着物价总水平上升。6% 的通胀率意味着现在一篮子商品的平均成本比一年前高出 6%，购买力下降。
8. Unemployment Types and Data | 失业类型与数据
Questions on unemployment often ask you to define and give examples of different types, and to analyse data.
失业问题常要求你定义并举例不同类型的失业，并分析数据。
Example: ‘Distinguish between cyclical and structural unemployment. Give an example of each.’
典型例题： “区分周期性失业与结构性失业，并分别举例。”
Step 1: Define cyclical unemployment: it is unemployment caused by a lack of aggregate demand during a recession, leading to falling output and job losses.
步骤1：定义周期性失业：在经济衰退期间由总需求不足导致的失业，导致产出下降和裁员。
Step 2: Example of cyclical: a construction worker laid off because fewer houses are being built during an economic downturn.
步骤2：周期性失业的例子：经济不景气时，因房屋建造数量减少而被解雇的建筑工人。
Step 3: Define structural unemployment: it occurs when there is a mismatch between workers’ skills and the skills demanded by employers, often due to technological change or industrial decline.
步骤3：定义结构性失业：劳动者技能与雇主需求不匹配时发生的失业，常因技术变革或产业衰退所致。
Step 4: Example of structural: a factory worker replaced by an automated machine, whose qualifications no longer match available jobs.
步骤4：结构性失业的例子：被自动化机器取代的工厂工人，其资历不再匹配现有工作岗位。
Step 5: Contrast both: cyclical is demand-side and temporary, while structural is supply-side and longer-term. Policies to deal with each are different.
步骤5：两者对比：周期性失业属于需求侧且是暂时的，结构性失业属于供给侧且更为长期。解决两者的政策不同。
9. Current Account Balance Analysis | 经常账户余额分析
Macroeconomic exam questions frequently ask you to explain causes and consequences of a current account deficit using economic reasoning.
宏观经济考试题常要求你用经济学推理来解释经常账户赤字的成因与后果。
Example: ‘Explain two reasons why the UK might experience a current account deficit.’
典型例题： “解释英国可能出现经常账户赤字的两个原因。”
Step 1: Recall that the current account includes trade in goods and services, primary income and secondary income. A deficit means outflows exceed inflows.
步骤1：回顾经常账户包括货物与服务贸易、初次收入与二次收入。赤字意味着资金流出大于流入。
Step 2: First reason: strong domestic consumer spending on imports. If UK consumers have high disposable income, they buy more imported goods, widening the trade deficit.
步骤2：第一个原因：国内消费强劲导致进口增加。若英国消费者可支配收入较高，会购买更多进口商品，加剧贸易逆差。
Step 3: Explain that this is often linked to a high marginal propensity to import. The import bill rises faster than export revenue.
步骤3：解释这往往与较高的边际进口倾向有关。进口支出增速超过出口收入。
Step 4: Second reason: low export competitiveness due to relatively high UK inflation or a strong pound. This makes UK exports more expensive abroad, reducing export volumes.
步骤4：第二个原因：出口竞争力弱，可能因为英国通胀相对较高或英镑坚挺。这导致英国出口品在国外更贵，出口量下降。
Step 5: Conclude that a persistent deficit could lead to exchange rate depreciation and borrowing from abroad, but it also indicates structural weaknesses in the domestic economy.
步骤5：总结持续赤字可能导致汇率贬值和对外举债，但也表明国内经济存在结构性弱点。
10. Evaluating Fiscal Policy Measures | 评估财政政策措施
Evaluation questions require you to consider both benefits and drawbacks of a policy. A typical command word is ‘evaluate’ or ‘discuss’.
评估题要求你权衡政策的利弊。典型的指令词是“评估”或“讨论”。
Example: ‘Evaluate the effectiveness of cutting income tax to increase economic growth.’
典型例题： “评估降低所得税以促进经济增长的有效性。”
Step 1: Explain the intended transmission mechanism. A cut in income tax raises disposable income, which boosts consumption and aggregate demand (AD). Show AD shifting right, leading to higher output and employment.
步骤1：解释预期的传导机制。降低所得税提高可支配收入，从而刺激消费和总需求（AD）。展示 AD 曲线右移，带来更高产出和就业。
Step 2: Identify how this can cause short-run growth. Diagram: AD increases from AD1 to AD2, real GDP rises, price level may rise slightly if the economy is near full capacity.
步骤2：说明这如何带来短期增长。图表：AD 从 AD1 增至 AD2，实际 GDP 上升，若经济接近充分产能，物价水平可能轻微上升。
Step 3: Then discuss drawbacks. The tax cut reduces government revenue, potentially increasing the budget deficit. If confidence is low, households may save the extra income rather than spend it, weakening the impact.
步骤3：然后讨论缺点。减税会减少政府收入，可能增加财政赤字。若信心不足，家庭可能将额外收入储蓄起来而非消费，削弱政策效果。
Step 4: Evaluate by considering the state of the economy. In a recession with spare capacity, the policy is likely to be more effective. Near full employment, it may be inflationary and less effective.
步骤4：通过考虑经济状况进行评估。在经济衰退且存在闲置产能时，该政策可能更有效。在接近充分就业时，可能引发通胀且效果较差。
Step 5: Give a reasoned conclusion. While cutting income tax can boost growth in the short run, long-term effectiveness depends on productivity improvements and consumer confidence. Therefore, it is not a guaranteed solution but can be part of a broader strategy.
步骤5：给出有推理的结论。虽然降低所得税可在短期内促进增长，但其长期有效性取决于生产力的提升与消费者信心。因此，这不是一个万能的解决方案，但可作为更广泛战略的一部分。
