📚 GCSE OCR Economics: Wage Determination | GCSE OCR 经济：工资决定考点精讲

The labour market is where employers and workers interact to determine the price of labour – the wage rate. Understanding how wages are set is a fundamental topic in GCSE OCR Economics, combining the forces of demand and supply with real-world factors such as government intervention and trade union power. This article breaks down every key concept you need to master for the exam.

劳动力市场是雇主与劳动者相互作用以决定劳动力价格——工资率——的场所。理解工资的决定方式是 GCSE OCR 经济学的核心课题，它结合了需求与供给的力量以及政府干预和工会力量等现实因素。本文带你逐一攻克考试中需要掌握的每一个关键概念。

1. Introduction to Labour Markets | 劳动力市场简介

In the labour market, households supply their labour services, while firms demand labour to produce goods and services. The price of labour is the wage rate. Just like any other market, the interaction of supply and demand determines the equilibrium wage and the number of workers employed.

在劳动力市场中，家庭提供劳动服务，而企业需要劳动来生产商品和服务。劳动的价格就是工资率。与任何其他市场一样，供给与需求的相互作用决定了均衡工资和雇用的劳动者数量。

The labour market is unique because labour is not a homogeneous commodity; workers differ in skills, experience, location and preferences. This heterogeneity helps explain why wages vary widely across occupations and industries.

劳动力市场很独特，因为劳动并非同质商品；劳动者在技能、经验、地点和偏好上各不相同。这种异质性有助于解释为什么不同职业和行业的工资差异很大。

2. The Demand for Labour | 劳动需求

Labour is a derived demand – employers demand workers not for their own sake, but because they contribute to producing goods and services that can be sold for revenue. The demand for labour therefore depends heavily on the demand for the final product.

劳动是一种派生需求——雇主需求工人不是为了工人本身，而是因为他们对生产能够售出并带来收入的产品有贡献。因此，劳动需求在很大程度上取决于对最终产品的需求。

The theory of marginal revenue product (MRP) explains how many workers a profit-maximising firm will hire. A worker’s MRP is the extra revenue the firm earns from employing one additional unit of labour. It can be calculated as:

边际收益产量（MRP）理论解释了追求利润最大化的企业会雇用多少工人。一个工人的 MRP 是企业多雇用一单位劳动所获得的额外收益。它可以这样计算：

MRP = MPP × MR

where MPP is the marginal physical product (the extra output produced by an additional worker) and MR is the marginal revenue (the additional revenue from selling one more unit of output).

其中 MPP 是边际实物产品（多雇一个工人带来的额外产出），MR 是边际收益（多销售一单位产出带来的额外收入）。

In a perfectly competitive labour market, a firm will continue to hire workers as long as the MRP is greater than or equal to the wage rate. The point where MRP = wage rate gives the profit-maximising level of employment. This means the firm’s labour demand curve is its MRP curve.

在完全竞争的劳动力市场中，只要 MRP 大于或等于工资率，企业就会继续雇用工人。MRP = 工资率的点给出了利润最大化的雇用量。这意味着企业的劳动需求曲线就是它的 MRP 曲线。

3. Factors Affecting the Demand for Labour | 影响劳动需求的因素

Several key factors can shift the entire demand curve for labour, leading to a higher or lower quantity of labour demanded at any given wage.

一些关键因素会使整个劳动需求曲线发生移动，导致在任何给定工资水平上劳动需求量的增加或减少。

Product demand: If consumer demand for the final good rises, firms need to produce more and will demand more labour at each wage rate (a rightward shift). The opposite occurs if demand falls.

产品需求：如果消费者对最终产品的需求上升，企业需要生产更多，从而在每个工资率上对劳动的需求都会增加（需求曲线向右移动）。如果需求下降，则相反。

Labour productivity: An increase in productivity (higher MPP) makes each worker more valuable, raising MRP and shifting the demand curve to the right. Training, better technology and improved management can all boost productivity.

劳动生产率：生产率提高（更高的 MPP）使每个工人更有价值，提高了 MRP，使需求曲线向右移动。培训、更好的技术和管理改进都能提高生产率。

Cost of capital: If the price of machinery falls, firms may substitute capital for labour, reducing labour demand (a leftward shift). Conversely, if capital becomes more expensive, labour demand might increase.

资本成本：如果机器的价格下降，企业可能会用资本替代劳动，减少劳动需求（需求曲线向左移动）。反之，如果资本变得更昂贵，劳动需求可能会增加。

Technology: Advances in technology can have ambiguous effects. Automation may replace workers, reducing demand, but new technology can also create new tasks and increase productivity, raising demand for skilled labour.

技术：技术进步可能产生模糊的影响。自动化可能取代工人，减少需求，但新技术也可能创造新的任务并提高生产率，从而增加对熟练劳动的需求。

4. The Supply of Labour | 劳动供给

The supply of labour refers to the number of hours that workers are willing and able to work at a given wage rate. For an individual firm in a competitive market, the supply of labour is perfectly elastic – the firm can hire as many workers as it wishes at the going market wage. However, the market supply curve is typically upward-sloping.

劳动供给指在给定工资率下劳动者愿意并能够工作的小时数。对于竞争市场中的单个企业来说，劳动供给是完全弹性的——企业可以以通行的市场工资任意雇用工人。但是，市场供给曲线通常是向上倾斜的。

At the market level, the upward slope reflects that higher wages attract more people into the workforce and encourage existing workers to offer more hours. Yet the relationship is not always straightforward – the income and substitution effects can cause an individual’s labour supply curve to bend backwards at very high wage rates (though this is a higher-level refinement).

在市场层面，向上的斜率反映了更高的工资吸引了更多人进入劳动力市场，并鼓励现有劳动者提供更多工时。但这种关系并不总是简单的——收入效应和替代效应可能导致个人的劳动供给曲线在非常高的工资率上向后弯曲（尽管这属于更高阶的内容）。

5. Factors Affecting the Supply of Labour | 影响劳动供给的因素

Shifts in the labour supply curve can change the equilibrium wage significantly. The main determinants of labour supply include:

劳动供给曲线的移动会显著改变均衡工资。劳动供给的主要决定因素包括：

Wages in alternative occupations: If wages rise in a rival industry, some workers may switch, reducing the supply of labour in the original market (a leftward shift).

替代职业的工资：如果竞争行业的工资上升，一些工人可能转换工作，减少了原市场的劳动供给（供给曲线向左移动）。

Barriers to entry: Professions that require lengthy training or professional qualifications (e.g. medicine, law) tend to have restricted supply, pushing wages upward. Reducing entry requirements would increase supply.

进入壁垒：需要长期培训或专业资格的职业（如医生、律师）往往供给受到限制，从而推高工资。降低进入要求将增加供给。

Demographics and migration: An increase in the working-age population or net inward migration expands the labour force, shifting the supply curve to the right. An ageing population may reduce supply over time.

人口结构与移民：劳动年龄人口增加或净流入移民扩大了劳动力队伍，使供给曲线向右移动。人口老龄化则可能随着时间推移减少供给。

Tax and benefit systems: Higher income taxes may reduce the incentive to work, shifting supply leftwards. Conversely, cuts in welfare benefits may push more people to seek work, increasing supply.

税收与福利制度：较高的所得税可能降低工作激励，使供给向左移动。相反，削减福利可能促使更多人寻找工作，增加供给。

Non-wage factors: Job satisfaction, working conditions, flexibility and job security all affect the attractiveness of a job and therefore the supply of labour to that occupation.

非工资因素：工作满意度、工作条件、灵活性和工作保障都会影响一份工作的吸引力，从而影响该职业的劳动供给。

6. Equilibrium Wage Determination | 均衡工资决定

Equilibrium in a competitive labour market occurs where the demand for labour equals the supply of labour. At this point, the wage rate is stable – there is no tendency for change because the number of workers firms wish to hire exactly matches the number of workers willing to work.

竞争性劳动力市场的均衡发生在劳动需求等于劳动供给之处。在这个点上，工资率是稳定的——因为没有变化的趋势，企业希望雇用的工人数量恰好等于愿意工作的工人数量。

If the wage is above equilibrium, there is an excess supply of labour, meaning unemployment exists as more people are looking for work than there are jobs available. If the wage is below equilibrium, there is an excess demand for labour, leading to labour shortages and upward pressure on wages.

如果工资高于均衡水平，就会出现劳动超额供给，意味着存在失业，因为寻找工作的人数多于可提供的岗位。如果工资低于均衡水平，就会出现劳动超额需求，导致劳动力短缺和工资上涨的压力。

The equilibrium wage is often called the market-clearing wage because it clears the market of any surpluses or shortages.

均衡工资常被称为市场出清工资，因为它出清了市场中所有的过剩或短缺。

7. Shifts in Demand and Supply | 需求与供给的变动

Exam questions frequently ask you to analyse how changes in demand-side or supply-side factors affect the wage rate and employment level.

考试题目经常会要求你分析需求方或供给方因素的变化如何影响工资率和就业水平。

For example, an increase in demand for labour (due to higher product demand) shifts the demand curve rightwards, raising both the equilibrium wage and the level of employment. A decrease in labour supply (perhaps because of stricter immigration controls) shifts the supply curve leftwards, increasing the wage rate but reducing the quantity of labour employed.

例如，劳动需求的增加（由于产品需求上升）使得需求曲线右移，提高了均衡工资和就业水平。劳动供给的减少（或许因为更严格的移民管制）使得供给曲线左移，提高了工资率但减少了劳动雇用量。

You should be able to draw these shifts on a labour market diagram (wage on the vertical axis, quantity of labour on the horizontal axis) and comment on the new equilibrium.

你应该能够在劳动力市场图示（纵轴为工资，横轴为劳动数量）上画出这些移动，并对新的均衡进行评注。

When both demand and supply shift simultaneously, the net effect on the wage and employment depends on the relative magnitude of the shifts. For instance, a rise in both demand and supply will definitely increase employment, but the wage change is ambiguous without further information.

当需求和供给同时移动时，对工资和就业的净效应取决于移动的相对幅度。例如，需求和供给同时增加一定会增加就业，但工资的变动在没有进一步信息的情况下是无法确定的。

8. Wage Differentials | 工资差异

Why do some workers earn far more than others? Wage differentials are the differences in wages across occupations, industries, regions and individuals. The OCR specification expects you to explain these using demand and supply analysis.

为什么有些工人的收入远远高于其他人？工资差异是指不同职业、行业、地区和个人之间的工资差别。OCR 大纲要求你用需求与供给分析来解释这些差异。

Skill and human capital: Highly skilled workers (doctors, engineers) have a higher MRP, driving up demand. At the same time, supply is restricted by the need for long training, resulting in high equilibrium wages.

技能与人力资本：高技能工人（医生、工程师）有更高的 MRP，推高了需求。同时，由于需要长期培训，供给受到限制，导致高均衡工资。

Compensating differentials: Jobs that are dangerous, unpleasant or involve unsocial hours (e.g. night shifts, mining) often pay higher wages to attract workers, compensating them for the negative aspects of the job.

补偿性差异：危险、令人不悦或涉及非社交时间的工作（如夜班、采矿）通常支付更高的工资来吸引工人，以补偿工作的负面方面。

Discrimination: Prejudice on the grounds of gender, race or age can limit the supply of certain groups to high-paying jobs or reduce the demand for their labour, causing unjust wage gaps.

歧视：基于性别、种族或年龄的偏见会限制某些群体进入高薪工作的供给，或减少对他们的劳动需求，造成不公正的工资差距。

Trade union power: Strong unions can bargain for higher wages for their members, creating a wage differential between unionised and non-unionised workers.

工会力量：强大的工会可以为其成员争取更高的工资，在工会化与非工会化工人之间造成工资差异。

9. Government Intervention: Minimum Wage | 政府干预：最低工资

The government can set a legal minimum wage (a price floor in the labour market) to protect low-paid workers. In the UK, this is called the National Living Wage for workers aged 23 and over, with lower rates for younger age groups.

政府可以设定法定最低工资（劳动力市场中的价格下限）来保护低薪工人。在英国，这对于 23 岁及以上的工人被称为国民生活工资，对较年轻的年龄段有较低的费率。

A binding minimum wage is set above the market-clearing equilibrium. At this higher wage, the quantity of labour supplied exceeds the quantity demanded, creating a potential surplus of labour – classical unemployment. Critics argue that a minimum wage can therefore reduce employment among low-skilled workers.

有效的最低工资被设定在市场出清均衡之上。在这个更高的工资水平上，劳动供给量超过了需求量，造成了潜在的劳动过剩——古典失业。批评者认为，最低工资因此可能减少低技能工人的就业。

However, many economists point out that in monopsony labour markets (where a single buyer dominates), a moderate minimum wage can actually increase employment by preventing employers from exploiting their wage-setting power. The evidence on real-world employment effects is mixed.

然而，许多经济学家指出，在买方垄断的劳动力市场中（单一买方占主导），适度的最低工资实际上可以通过阻止雇主利用工资制定权力来增加就业。关于现实世界就业效应的证据是复杂的。

10. Trade Unions and Wages | 工会与工资

A trade union is an organisation of workers that aims to protect and improve its members’ pay and working conditions through collective bargaining with employers. By representing workers collectively, unions can shift the balance of power away from individual workers towards the workforce as a whole.

工会是一个工人组织，旨在通过与雇主进行集体谈判来保护和改善其成员的薪酬与工作条件。通过集体代表工人，工会可以将力量平衡从个体工人转移到整个劳动力队伍。

Unions can raise wages by restricting labour supply (e.g. through closed shops or requiring specific qualifications) or by using their bargaining strength to negotiate above-equilibrium wages. This can result in a higher wage for union members but may reduce employment in that sector if employers respond by cutting jobs.

工会可以通过限制劳动供给（例如通过封闭工厂或要求特定资格）或利用其谈判力量来协商高于均衡的工资。这可能导致工会成员获得更高的工资，但如果雇主以削减岗位作为回应，该部门的就业可能会减少。

In modern economies, union membership has fallen in many countries, weakening their ability to influence wages. Nevertheless, unions remain important in certain public sector jobs and skilled trades.

在现代经济中，许多国家的工会会员数量有所下降，削弱了它们影响工资的能力。尽管如此，工会在某些公共部门工作和熟练行业中仍然很重要。

11. Elasticity of Labour Demand and Supply | 劳动需求与供给弹性

Wage elasticity of labour demand measures how responsive the quantity of labour demanded is to a change in the wage rate. It influences how a wage change affects total employment. Labour demand tends to be more elastic when:

劳动需求的工资弹性衡量的是劳动需求量对工资率变化的反应程度。它影响着工资变化如何影响总就业。在以下情况下劳动需求往往更具弹性：

Labour costs are a large proportion of total costs.

劳动成本占总成本的比重较大。
It is easy to substitute capital for labour.

用资本替代劳动很容易。
The final product has elastic demand, meaning that rising costs can be passed on less easily.

最终产品的需求弹性较大，意味着成本上升较难转嫁。
The time period is longer, giving firms more scope to adjust.

时间跨度更长，使企业有更多调整空间。

Wage elasticity of labour supply captures how the quantity of labour supplied reacts to wage changes. Supply of labour to a particular occupation is more elastic when workers have many alternative job opportunities and when there are low barriers to entry.

劳动供给的工资弹性反映的是劳动供给量对工资变化的反应。当一个职业的工人拥有许多替代工作机会且进入壁垒较低时，对该职业的劳动供给更具弹性。

These elasticities are crucial in evaluating the impact of a minimum wage or union-negotiated wage increase. The more elastic the demand for labour, the greater the employment loss from setting a wage above equilibrium.

这些弹性对于评估最低工资或工会协商加薪的影响至关重要。劳动需求越有弹性，设定高于均衡水平的工资所造成的就业损失就越大。

12. Real vs Nominal Wages | 实际工资与名义工资

It is essential to distinguish between nominal wages (the money wage rate, e.g. £10 per hour) and real wages (the purchasing power of wages, i.e. the quantity of goods and services that wage can buy).

区分名义工资（货币工资率，例如每小时 10 英镑）和实际工资（工资的购买力，即该工资能购买的商品和服务数量）至关重要。

A worker’s standard of living depends on real wages, not nominal wages. If nominal wages rise by 3% but inflation is 5%, real wages have actually fallen by about 2% – workers are worse off in terms of what they can afford.

工人的生活水平取决于实际工资，而非名义工资。如果名义工资上涨 3%，但通胀率为 5%，那么实际工资实际上下降了约 2%——从所能负担的东西来看，工人的境况变差了。

Real wage growth is driven by productivity improvements. When workers produce more per hour (higher MPP), firms can afford to pay higher wages without raising prices, leading to genuine increases in living standards.

实际工资的增长受生产率提高的驱动。当工人每小时产出更多（更高的 MPP）时，企业能够在不大幅提高价格的情况下支付更高的工资，从而实现真正的生活水平提升。

Be ready to analyse data on wage growth alongside inflation data to assess changes in living standards, a classic exam skill.

要准备好分析工资增长数据以及通胀数据，以评估生活水平的变化，这是一项经典的考试技能。
