📚 GCSE WJEC Economics: Labour Market | GCSE WJEC 经济：劳动力市场考点精讲
The labour market is a crucial factor market where the forces of demand and supply interact to determine wages and employment levels. Understanding how labour markets work is essential for analysing economic issues such as unemployment, inequality, and the impact of government policies. In the WJEC GCSE Economics specification, you will explore the demand for and supply of labour, wage determination, trade unions, and government intervention.
劳动力市场是一个关键的要素市场，供需力量相互作用决定工资和就业水平。理解劳动力市场的运行对于分析失业、不平等以及政府政策的影响至关重要。在WJEC GCSE经济学大纲中，你将探讨劳动力的需求与供给、工资决定、工会和政府干预。
1. What is the Labour Market? | 什么是劳动力市场？
The labour market is where workers offer their services and employers hire labour. The price of labour is the wage rate. Unlike goods markets, labour is a derived demand – it depends on the demand for the goods and services that labour produces.
劳动力市场是工人提供服务、雇主雇佣劳动力的场所。劳动力的价格是工资率。与商品市场不同，劳动力是一种派生需求——它取决于对劳动力所生产的商品和服务的需求。
Households supply labour, and firms demand labour. The interaction of supply and demand determines the equilibrium wage and the number of workers employed.
家庭供给劳动力，企业需求劳动力。供给和需求的相互作用决定了均衡工资和就业人数。
2. Demand for Labour | 劳动力需求
Labour demand is derived from the demand for the product it helps produce. If demand for smartphones rises, firms will demand more workers to make smartphones. The demand curve for labour slopes downward: as wages fall, firms hire more workers because it becomes cheaper to employ them.
劳动力需求源于其帮助生产的产品的需求。如果对智能手机的需求上升，企业将需要更多工人来制造智能手机。劳动力需求曲线向下倾斜：随着工资下降，企业雇佣更多工人，因为雇佣成本降低。
Firms consider the marginal revenue product of labour (MRP) – the extra revenue gained from employing one additional worker. A profit-maximising firm will hire workers up to the point where MRP equals the wage.
企业考虑劳动的边际收益产品（MRP）——雇佣额外一名工人带来的额外收入。利润最大化的企业会一直雇佣工人直到MRP等于工资。
3. Supply of Labour | 劳动力供给
The supply of labour is the number of hours workers are willing and able to offer at each wage rate. The supply curve for labour usually slopes upward: higher wages incentivise more people to enter the workforce or work longer hours.
劳动力供给是工人在每种工资率下愿意且能够提供的工作小时数。劳动力供给曲线通常向上倾斜：更高的工资激励更多人加入劳动力队伍或延长工作时间。
Key factors affecting labour supply include the size of the working-age population, migration, education and training, preferences for leisure, and non-wage benefits such as working conditions.
影响劳动力供给的关键因素包括劳动年龄人口规模、移民、教育和培训、休闲偏好以及工作条件等非工资福利。
4. How are Wages Determined? | 工资如何决定？
The equilibrium wage rate is set where labour demand equals labour supply. If the wage is above equilibrium, there is a surplus of labour (unemployment). If below, there is a shortage of labour, pushing wages up.
均衡工资率在劳动力需求等于劳动力供给时确定。如果工资高于均衡水平，就会出现劳动力剩余（失业）。如果低于均衡水平，就会出现劳动力短缺，推动工资上涨。
In reality, wages vary widely due to differences in productivity, skills, bargaining power, and market imperfections.
在现实中，由于生产力、技能、议价能力和市场不完善等因素，工资差异很大。
5. Factors that Shift Labour Demand | 移动劳动力需求的因素
Changes in consumer demand: If consumers buy more of a product, firms will need more workers to meet that demand, shifting the labour demand curve to the right.
消费者需求变化：如果消费者购买更多产品，企业将需要更多工人来满足需求，从而使劳动力需求曲线向右移动。
Productivity of labour: Improvements in technology or workers’ skills can increase labour demand as each worker becomes more productive.
劳动生产率：技术进步或工人技能提高可以增加劳动力需求，因为每个工人的生产力更高。
Price of capital: If machinery becomes cheaper, firms might substitute capital for labour, reducing labour demand. However, if capital complements labour, demand may increase.
资本价格：如果机器变得更便宜，企业可能用资本替代劳动力，减少劳动力需求。但如果资本与劳动力互补，需求可能增加。
Government regulations and subsidies: Policies such as hiring subsidies or tax breaks for employing workers can increase labour demand.
政府法规和补贴：如雇佣补贴或雇佣税收减免等政策可以增加劳动力需求。
6. Factors that Shift Labour Supply | 移动劳动力供给的因素
Changes in the working-age population: An increase in population or net migration expands the labour supply, shifting the curve rightward.
劳动年龄人口变化：人口增长或净移民增加扩大了劳动力供给，使曲线向右移动。
Education and training time: If more people stay in full-time education longer, the immediate labour supply may reduce as fewer people are available to work.
教育和培训时间：如果更多人接受更长时间的全日制教育，即时劳动力供给可能减少，因为可工作的人口减少。
Changes in income tax and benefits: Lower income taxes make work more financially rewarding, increasing labour supply. Higher welfare benefits might reduce the incentive to seek work.
所得税和福利变化：更低的所得税使工作在经济上更有回报，增加了劳动力供给。更高的福利可能降低寻找工作的动机。
Non-wage factors and social attitudes: Improved working conditions, flexible hours, or increased female participation can attract more workers into the labour force.
非工资因素和社会态度：改善工作条件、弹性工作时间或女性劳动参与率提高可以吸引更多人加入劳动力队伍。
7. Wage Differentials | 工资差异
Wage differentials exist because workers have different skills, qualifications, and productivity. Additionally, labour markets are often segmented by geography, industry, and discrimination.
工资差异存在是因为工人拥有不同的技能、资质和生产力。此外，劳动力市场经常因地理、行业和歧视而分割。
Skilled workers such as doctors earn more than unskilled workers because their labour is scarcer and demands lengthy training. This creates a wage premium for human capital.
医生等熟练工人比非熟练工人挣得多，因为他们的劳动力更稀缺且需要长期培训。这为人形资本创造了工资溢价。
Geographical immobility can cause regional wage gaps. Workers in high-cost areas like London often receive higher nominal wages to compensate for living expenses.
地理不流动性会导致地区工资差距。伦敦等高成本地区的工人往往获得更高的名义工资以补偿生活费用。
Discrimination based on gender, ethnicity, or age can unfairly cause wage gaps. Equal pay legislation aims to eliminate such disparities.
基于性别、种族或年龄的歧视会不公平地导致工资差距。同工同酬立法旨在消除这种差距。
8. Trade Unions | 工会
Trade unions are organisations that protect workers’ interests and negotiate with employers for better wages, conditions, and benefits. They can restrict labour supply, enabling them to push wages above the competitive equilibrium.
工会是保护工人利益并与雇主谈判以争取更好工资、条件和福利的组织。它们可以限制劳动力供给，从而将工资推高到竞争均衡之上。
Through collective bargaining, unions can increase wages for their members. However, if wages are set too high above equilibrium, some workers may become unemployed because firms hire fewer workers at the higher wage.
通过集体谈判，工会可以提高其成员的工资。然而，如果工资设定过高超过均衡水平，一些工人可能会失业，因为企业在更高工资下雇佣的工人减少。
The effectiveness of a union depends on its membership density and the elasticity of demand for the product. When labour demand is inelastic, wage increases cause smaller job losses.
工会的效果取决于其会员密度和产品需求的弹性。当劳动力需求缺乏弹性时，工资上涨导致的就业损失较小。
9. The National Minimum Wage | 国家最低工资
The National Minimum Wage (NMW) is a legal minimum hourly pay rate set by the government. It acts as a price floor in the labour market, preventing wages from falling below a certain level.
国家最低工资（NMW）是政府设定的法定最低小时工资率。它充当劳动力市场的价格下限，防止工资低于某一水平。
If the NMW is set above the equilibrium wage, it can create a surplus of labour – classical unemployment – as the quantity of labour supplied exceeds the quantity demanded. The extent depends on the elasticity of labour demand.
如果最低工资设定在均衡工资之上，可能会导致劳动力过剩——古典失业——因为劳动力供给量超过了需求量。其程度取决于劳动力需求的弹性。
Advantages of the NMW include reducing in-work poverty, addressing monopsony power, and improving worker motivation. Disadvantages include potential job losses for low-skilled workers and higher costs for firms, which may be passed on as higher prices.
最低工资的优点包括减少在职贫困、解决买方垄断权问题和提高员工积极性。缺点包括低技能工人可能失业、企业成本增加并可能转嫁为更高物价。
10. Government Intervention and Discrimination | 政府干预与歧视
Apart from the minimum wage, the government intervenes through equality legislation to reduce discrimination in hiring, pay, and promotion. This helps labour markets work more efficiently and fairly.
除了最低工资，政府还通过平等立法进行干预，以减少招聘、薪酬和晋升中的歧视。这有助于劳动力市场更加高效和公平地运行。
Policies such as the Equality Act protect workers based on characteristics like gender, race, disability, and age. They ensure wages reflect productivity rather than prejudice.
《平等法案》等政策保护工人免受基于性别、种族、残疾和年龄等特征的歧视。它们确保工资反映生产力而非偏见。
Government training and education schemes improve occupational mobility, reduce structural unemployment, and help workers acquire skills that boost their MRP.
政府培训和教育计划改善职业流动性，减少结构性失业，帮助工人获得提高其MRP的技能。
11. Elasticity of Labour Demand and Supply | 劳动力供需弹性
Elasticity of labour demand measures the responsiveness of the quantity of labour demanded to changes in the wage rate. It is calculated as:
劳动力需求弹性衡量劳动力需求量对工资率变化的反应程度。计算公式为：
Elasticity of labour demand = %Δ Quantity of labour demanded / %Δ Wage rate
Determinants include the ease of substituting capital for labour, the price elasticity of demand for the final product, the proportion of labour costs in total costs, and the time period. Demand is more elastic when substitution is easy
