1. Definition of Unemployment | 失业的定义

Unemployment refers to the number of people who are willing and able to work, are actively seeking work, but are currently without a job. In economics, not everyone without a job is counted as unemployed. For instance, students, retirees, and those who have stopped looking for work are not considered part of the labour force and thus are not unemployed.

失业指的是那些愿意并且有能力工作、正在积极寻找工作但目前没有工作的人数。在经济学中，并非所有没有工作的人都算作失业。例如，学生、退休人员以及那些不再寻找工作的人，不被视为劳动力的一部分，因此不属于失业者。

The labour force (also called the working population) consists of all those who are employed plus those who are unemployed but actively seeking work. The unemployment rate is calculated as:

劳动力（也称为工作人口）由所有就业者加上那些失业但正在积极寻找工作的人组成。失业率的计算公式如下：

Unemployment rate = (Number of unemployed / Labour force) × 100

失业率 =（失业人数 / 劳动力总数）× 100

It is crucial to memorise this formula for the exam. Be careful: the denominator is the labour force, not the total population. Many candidates lose marks by dividing by the wrong figure.

在考试中牢记这个公式至关重要。要注意：分母是劳动力总数，而不是总人口。许多考生因除以错误的数据而失分。

2. Measuring Unemployment | 衡量失业

In the UK, two main methods are used to measure unemployment: the Claimant Count and the International Labour Organisation (ILO) Labour Force Survey. The Edexcel IGCSE specification expects you to know both and to evaluate their advantages and disadvantages.

在英国，主要使用两种方法来衡量失业：申请失业金人数和国际劳工组织（ILO）的劳动力调查。Edexcel IGCSE大纲要求你了解这两种方法，并能够评价它们的优缺点。

The Claimant Count records the number of people claiming Jobseeker’s Allowance (JSA) or other unemployment-related benefits. It is relatively cheap and quick to collect data from administrative records. However, it may underestimate true unemployment because not all unemployed people are eligible for or choose to claim benefits. Some people may be too proud to claim, have savings above the threshold, or be part of a household with a working partner. The rules for eligibility can also change, making comparisons over time difficult.

申请失业金人数统计的是领取求职津贴（JSA）或其他与失业相关福利的人数。它通过行政记录收集数据，相对便宜且快捷。然而，它可能低估真实失业水平，因为并非所有失业者都符合条件或选择申请福利。有些人可能出于自尊不愿申请，或者储蓄超过门槛，又或者家中已有在工作的伴侣。领取资格的规定也可能发生变化，使得跨时期比较变得困难。

The Labour Force Survey is a monthly sample survey of households, based on ILO definitions. People are counted as unemployed if they are out of work, have actively looked for work in the past four weeks, and are available to start work within the next two weeks. This measure is internationally comparable and includes those who do not claim benefits. On the downside, it is expensive to conduct and subject to sampling errors. Sometimes the two measures give different pictures of unemployment, which itself can be an exam question.

劳动力调查是根据ILO定义进行的月度家庭抽样调查。一个人如果处于无工作状态、在过去四周内积极寻找过工作，并且能够在接下来的两周内开始工作，就会被算作失业。这一衡量方式具有国际可比性，并包含了那些没有申请福利的人。其缺点在于执行成本高昂，且容易出现抽样误差。有时这两种衡量方式会给出不同的失业状况图景，这本身就可以成为一道考题。

3. Types and Causes of Unemployment | 失业的类型与成因

Economists classify unemployment into several distinct types. Knowing the causes of each type is one of the most examined areas in IGCSE Economics. The main categories are frictional, structural, cyclical (demand-deficient), seasonal, and voluntary versus involuntary unemployment.

经济学家将失业分为几种不同的类型。了解每种类型的成因是IGCSE经济学科最常考的内容之一。主要类别包括摩擦性失业、结构性失业、周期性失业（需求不足性失业）、季节性失业以及自愿性与非自愿性失业。

3.1 Frictional Unemployment | 摩擦性失业

Frictional unemployment occurs when workers are between jobs. It is usually short-term and reflects the time taken to search for a new job that matches their skills. Examples include a graduate looking for their first role or someone who has moved to a new city. It is often seen as inevitable and even beneficial if it leads to better job matches, but can be reduced by improving information flows in the labour market.

摩擦性失业发生在工人转换工作期间。它通常是短期的，反映了寻找一份与自身技能相匹配的新工作所需的时间。例如，毕业生寻找第一份工作，或者某人搬到了新城市后的求职过程。这通常被视为不可避免，如果它能带来更好的工作匹配，甚至是有益的，但可以通过改善劳动力市场的信息流动来减少。

3.2 Structural Unemployment | 结构性失业

Structural unemployment arises from a mismatch between the skills of the workforce and the needs of employers. This can be caused by long-term changes in the economy, such as deindustrialisation, technological advancement, or changes in comparative advantage. For instance, workers in a declining manufacturing industry may lack the digital skills needed in the growing service sector. Structural unemployment tends to be long-term and requires retraining or relocation to solve.

结构性失业源于劳动力的技能与雇主的需求之间的不匹配。这可能是由经济的长期变化引起的，例如去工业化、技术进步或比较优势的变化。例如，正在衰退的制造业工人可能缺乏不断增长的服务业所需的数字化技能。结构性失业通常是长期的，需要通过再培训或搬迁来解决。

3.3 Cyclical (Demand-deficient) Unemployment | 周期性（需求不足）失业

Cyclical unemployment occurs when there is insufficient aggregate demand in the economy to provide jobs for everyone who wants to work. It is linked to the business cycle: during a recession, demand for goods and services falls, firms reduce production and lay off workers. It is often the primary concern of macroeconomic policy. Keynesian economics argues that increasing aggregate demand through fiscal or monetary policy can reduce cyclical unemployment.

周期性失业发生在经济体中的总需求不足以为所有想工作的人提供就业岗位时。它与经济周期相关：在衰退期间，对商品和服务的需求下降，企业减少生产并裁员。这通常是宏观经济政策关注的首要问题。凯恩斯主义经济学认为，通过财政政策或货币政策增加总需求可以减少周期性失业。

3.4 Seasonal Unemployment | 季节性失业

Seasonal unemployment is linked to regular, predictable changes in demand during the year. Examples include tourism workers in beach resorts during winter or agricultural workers after harvest. It is common in certain sectors and is often excluded from seasonally adjusted data to give a clearer underlying picture.

季节性失业与一年中规律性、可预测的需求变化有关。例如，冬季的海滨度假区旅游业工作者，或收割后的农业工人。这在某些行业很常见，并且通常会在季节性调整后的数据中被剔除，以提供更清晰的潜在经济状况。

3.5 Voluntary vs Involuntary Unemployment | 自愿性与非自愿性失业

Voluntary unemployment occurs when workers choose not to accept a job at the current market wage rate, perhaps because the pay is too low, benefits are too generous, or they are waiting for a better offer. Involuntary unemployment happens when workers are willing to work at the going wage but cannot find a job. The classical view focuses on voluntary unemployment and argues that wages above equilibrium cause unemployment. Keynesians focus on involuntary unemployment caused by deficient demand.

自愿性失业发生在工人选择不按当前市场工资率接受工作时，可能是因为工资太低、福利过于慷慨，或者他们在等待更好的工作机会。非自愿性失业则是指工人愿意按现行工资水平工作，但无法找到工作。古典学派观点侧重于自愿性失业，认为高于均衡水平的工资会导致失业。凯恩斯主义者则关注由需求不足引起的非自愿性失业。

4. Consequences of Unemployment | 失业的后果

Unemployment has severe economic and social consequences for individuals, firms, the government, and the wider economy. The Edexcel exam often asks you to analyse these consequences in detail and to distinguish between the effects on different groups.

失业对个人、企业、政府和整体经济都有严重的经济和社会后果。Edexcel考试经常要求你详细分析这些后果，并区分对不同群体的影响。

For individuals: Loss of income reduces living standards and may lead to poverty, debt, and family breakdown. Prolonged unemployment can cause loss of skills (hysteresis), psychological stress, and poorer health. The unemployed may find it harder to get a job the longer they are out of work, creating a vicious cycle.

对个人而言：收入损失会降低生活水平，并可能导致贫困、债务和家庭破裂。长期失业会导致技能丧失（滞后效应）、心理压力和健康状况恶化。失业者失业时间越长，可能越难找到工作，从而形成恶性循环。

For firms: During periods of high unemployment, firms may face lower demand for their products. However, they might also find it easier to recruit workers and face less upward pressure on wages. On the other hand, in a depressed economy, demand for goods and services falls, reducing profits and investment.

对企业而言：在高失业率时期，企业可能会面临产品需求下降。然而，他们也可能发现更容易招聘工人，并且工资上涨的压力较小。另一方面，在经济不景气时，对商品和服务的需求下降，会减少利润和投资。

For the government: Higher unemployment means lower tax revenues (less income tax, VAT, and corporation tax) and higher government spending on welfare benefits. This can worsen the budget deficit and increase public debt. Governments may also face political pressure and social unrest.

对政府而言：更高的失业率意味着税收减少（所得税、增值税和公司税减少）以及福利支出增加。这会恶化预算赤字并增加公共债务。政府还可能面临政治压力和社会动荡。

For the economy as a whole: Unemployment wastes scarce resources and means the economy is operating inside its production possibility frontier. There is a loss of potential output (GDP gap). High unemployment can also lead to lower overall consumer confidence and a spiral of falling demand. The social costs, such as increased crime and health spending, further burden the economy.

对整体经济而言：失业浪费了稀缺资源，意味着经济在其生产可能性边界内运行。存在潜在产出的损失（GDP缺口）。高失业率还可能导致整体消费者信心下降和需求下降的螺旋。社会成本，如犯罪率上升和医疗支出增加，进一步加重经济负担。

5. The Natural Rate of Unemployment | 自然失业率

The natural rate of unemployment (also called the non-accelerating inflation rate of unemployment, NAIRU) is the rate of unemployment that exists when the economy is producing at its full potential output. It comprises frictional and structural unemployment, as these are always present even in a healthy economy. Cyclical unemployment, by contrast, is zero at the natural rate.

自然失业率（又称非加速通货膨胀失业率，NAIRU）是指当经济以其全部潜在产出水平生产时存在的失业率。它包含摩擦性失业和结构性失业，因为即使在健康的经济中，这些失业也始终存在。相比之下，周期性失业在自然失业率水平上为零。

Understanding the natural rate is important because it signals the limit to which expansionary demand management can sustainably reduce unemployment. If the government tries to push unemployment below the natural rate, the outcome may be rising inflation rather than a permanent fall in unemployment. Supply-side policies are needed to lower the natural rate itself by improving labour market flexibility and skills.

理解自然失业率很重要，因为它标志着扩张性需求管理政策能够可持续降低失业的限度。如果政府试图将失业率压低至自然率以下，结果可能是通胀上升，而不是失业率的永久下降。需要通过改善劳动力市场灵活性和技能等供给侧政策来降低自然失业率本身。

6. Policies to Reduce Unemployment | 减少失业的政策

Policies to tackle unemployment can be broadly divided into demand-side policies and supply-side policies. The Edexcel IGCSE requires you to evaluate different approaches, considering their effectiveness, costs, and any unintended consequences.

解决失业的政策大致可分为需求侧政策和供给侧政策。Edexcel IGCSE要求你评估不同的方法，考虑其有效性、成本以及任何非预期的后果。

6.1 Demand-side Policies | 需求侧政策

These aim to increase aggregate demand in the economy, thereby creating more jobs. They are particularly effective against cyclical unemployment.

这些政策旨在增加经济中的总需求，从而创造更多就业机会。它们对周期性和失业特别有效。

Fiscal policy: The government can increase its spending (e.g., on infrastructure projects) or cut taxes to boost consumption and investment. This shifts the AD curve to the right, increasing real GDP and employment. However, higher spending may lead to a budget deficit and crowding out of private investment. Tax cuts might be saved rather than spent if confidence is low.

财政政策：政府可以增加支出（例如基础设施项目）或减税，以刺激消费和投资。这将使总需求曲线向右移动，增加实际GDP和就业。然而，增加支出可能导致预算赤字和挤出私人投资。如果信心低迷，减税可能被储蓄起来而非用于消费。

Monetary policy: The central bank can lower interest rates to make borrowing cheaper, encouraging business expansion and consumer spending on credit. It can also use quantitative easing to increase the money supply. Lower interest rates, however, may not work if banks are unwilling to lend or if consumers and firms are pessimistic about the future (liquidity trap).

货币政策：中央银行可以降低利率，使借贷更便宜，鼓励企业扩张和消费者的信贷消费。它还可以使用量化宽松来增加货币供应。然而，如果银行不愿放贷，或者消费者和企业对未来悲观（流动性陷阱），降低利率可能无效。

6.2 Supply-side Policies | 供给侧政策

Supply-side policies aim to improve the productive capacity of the economy and make labour markets more flexible. They are crucial for reducing frictional, structural, and the natural rate of unemployment.

供给侧政策旨在提高经济的生产能力，并使劳动力市场更加灵活。它们对于减少摩擦性失业、结构性失业和自然失业率至关重要。

Examples include education and training programmes to equip workers with relevant skills (reducing occupational immobility), improving geographical mobility through housing and transport policies, reducing trade union power (though this is a contentious area), reforming benefits to ensure work always pays more than welfare, and lowering employment taxes to incentivise hiring. Investment in technology and infrastructure also raises productivity and demand for labour in the long run.

例子包括教育和培训项目，使工人具备相关技能（减少职业不流动性）；通过住房和交通政策改善地理流动性；降低工会力量（尽管这是一个有争议的领域）；改革福利制度，确保工作收入始终高于福利；以及降低雇佣税以激励招聘。对技术和基础设施的投资也能在长期提高生产力和劳动力需求。

Supply-side policies take time to work and can be expensive, but they address the root causes of unemployment and increase the economy’s long-run growth potential without causing inflation.

供给侧政策需要时间才能见效，且成本高昂，但它们解决了失业的根本原因，并在不引起通胀的情况下提高了经济的长期增长潜力。

7. Conflicts between Objectives | 目标之间的冲突

Policies to reduce unemployment can conflict with other macroeconomic objectives. Edexcel often tests your understanding of these trade-offs. For example, expansionary demand-side policies might reduce unemployment but cause demand-pull inflation, especially if the economy is close to full capacity. There may also be a conflict with the balance of payments: rising incomes boost imports, potentially worsening the current account.

减少失业的政策可能与其他宏观经济目标产生冲突。Edexcel经常考察你对这些权衡的理解。例如，扩张性需求侧政策可能会减少失业，但会引起需求拉动型通胀，特别是在经济接近充分产能时。还可能与国际收支产生冲突：收入增加会推高进口，从而可能恶化经常账户。

On the supply side, policies such as making it easier to hire and fire workers (labour market flexibility) can reduce unemployment but may increase job insecurity and inequality. Cutting benefits to incentivise work can reduce voluntary unemployment but may increase poverty if wages are low. Reducing unemployment through protectionist measures would conflict with the objective of free trade and could lead to retaliation. A good evaluation in the exam acknowledges that governments often face difficult choices and must prioritise objectives depending on the economic context.

在供给侧，诸如使雇佣和解聘工人更容易（劳动力市场灵活性）的政策可以减少失业，但可能增加工作不安全感和不平等。削减福利以激励工作可以减少自愿性失业，但如果工资很低，则可能加剧贫困。通过保护主义措施减少失业将与自由贸易的目标冲突，并可能导致报复。考试中一个好的评估要承认政府常常面临艰难的选择，必须根据经济环境来确定目标的优先次序。

8. Real-world Examples and Case Studies | 现实案例与实例研究

Using real-world examples in your answers can significantly boost your marks. Edexcel expects you to apply your knowledge to actual economic situations. Some useful examples include: the UK after the 2008 financial crisis, where cyclical unemployment rose sharply but was tackled by low interest rates and quantitative easing; Spain’s high youth unemployment due to structural problems in the labour market before recent reforms; and Germany’s use of short-time working schemes (Kurzarbeit) to prevent mass unemployment during downturns.

在答案中使用现实世界的例子可以显著提高你的分数。Edexcel期望你将知识应用到实际的经济情境中。一些有用的例子包括：2008年金融危机后的英国，当时周期性失业急剧上升，但通过低利率和量化宽松政策得到应对；西班牙因近年改革前劳动力市场的结构性问题导致的高青年失业率；以及德国在经济低迷期使用短时工作安排（Kurzarbeit）来防止大规模失业。

When discussing frictional unemployment, you could mention online job platforms that reduce information gaps. For structural unemployment, mention the decline of coal mining in the UK and the need for retraining miners. Always link the example explicitly to the type of unemployment or policy you are analysing.

在讨论摩擦性失业时，你可以提及那些减少信息差距的在线招聘平台。对于结构性失业，可以提到英国煤炭开采业的衰落以及对矿工进行再培训的必要性。务必明确地将例子与你正在分析的失业类型或政策联系起来。

9. Common Exam Mistakes and Tips | 常见考试错误与技巧

Many students confuse the types of unemployment, especially mixing up structural and cyclical. Remember: structural is about skills mismatch and long-term decline of industries; cyclical is about lack of overall demand in the whole economy. Also, be precise when defining unemployment: it is not simply ‘people without a job’. Use the definition including ‘willing and able to work, actively seeking work’.

许多学生混淆了失业的类型，尤其是将结构性失业与周期性失业搞混。要记住：结构性失业与技能不匹配和行业的长期衰退有关；周期性失业则是关于整个经济中总需求的缺乏。此外，在定义失业时要准确：它不仅仅是“没有工作的人”。要使用包含“愿意且有能力工作、正在积极寻找工作”的定义。

When drawing diagrams, label them fully and show the shift in AD or LRAS clearly. In evaluation, always consider both sides: for example, a policy may be effective in the short term but create side effects in the long term, or it may work for cyclical but not structural unemployment. Always answer the specific question; do not write everything you know about unemployment.

在绘制图表时，要完整地标记，并清楚地展示总需求曲线或长期总供给曲线的移动。在评估时，要始终考虑两方面：例如，某项政策可能在短期内有效，但在长期会产生副作用；或者它可能对周期性失业有效，但对结构性失业无效。始终回答具体问题；不要把你所知道的关于失业的一切都写上去。
