MICRO LABOUR MARKETS

What is meant by "derived demand" in the context of labour markets?

the demand for labour depends directly on consumer demand for the final goods and services that workers produce.

What is Marginal Revenue Product of Labour (MRPL), and what is its mathematical formula?

MRPL is the additional revenue a firm earns by hiring one extra unit of labour.

MRPL = MPL x MR

• MPL (Marginal product of labour): The extra physical output a firm gets when it hires one additional worker

• MR: The extra money (revenue) a firm pulls in from selling one additional unit of its product.

• MR = CHANGE ON TOTAL REV / CHANGE IN Q SOLD

• MPL = CHANGE IN TOTAL OUTPUT / CHANGE IN LABOUR

MPL AND MR?

MRPL is the additional revenue a firm earns by hiring one extra unit of labour.

MRPL = MPL x MR

• MPL (Marginal product of labour): The extra physical output a firm gets when it hires one additional worker

• MR: The extra money (revenue) a firm pulls in from selling one additional unit of its product.

• MR = CHANGE ON TOTAL REV / CHANGE IN Q SOLD

• MPL = CHANGE IN TOTAL OUTPUT / CHANGE IN LABOUR

Why is a profit-maximising firm's labour demand curve downward sloping in the short run?

Because of the Law of Diminishing Marginal Returns. As more workers are added to fixed FOP, the marginal product of each additional worker (MPL) falls, causing MRPL to decline. Therefore, firms will only hire extra workers at a lower wage rate.

Explain the difference between the Cost Effect and the Substitution Effect along a downward-sloping labour demand curve:

• Cost Effect: Higher wages increase total production costs, leading to lower output and fewer workers hired (contraction).

• Substitution Effect: Higher wages make labour relatively more expensive than capital, incentivising firms to substitute workers with machinery (contraction).

What are four main factors that cause the Labour Demand curve to shift to the right?

• Increase in consumer demand for the final good/service.

• Increase in labour productivity (MPL).

• Government employment subsidies given to hiring firms.

• Increase in the price of substitute capital equipment.

Define Wage Elasticity of Demand for Labour (WED)

The responsiveness of the quantity of labour demanded to a change in the wage rate

WED= %CHANGE OF QUANTITY OF LABOUR DEMAND / %CHANGE OF WAGE RATE

How do "Labour costs as a % of total costs" and "Ease of factor substitution" affect WED?

Labour % of Total Costs: If labour accounts for a high proportion of costs, WED is elastic

Ease of Factor Substitution: If capital can easily replace labour, WED is elastic

Why is WED more elastic in the long run than in the short run?

In the long run, firms have sufficient time to alter production processes, install automated machinery, or reorganize workflows to replace expensive labour with capital.

What are the three key determinants of the market supply curve for labour?

• Substitution effect: Higher wages encourage individuals to trade leisure for work hours.

• Entrance/Exit effect: Higher wages attract new workers into the market from other industries or outside the workforce.

• Income effect: Impact on hours worked as income changes

Explain why an individual worker's labour supply curve (hours worked) can bend backwards at higher wage rates

• At lower wages, Substitution Effect > Income Effect (rising wage implies more hours worked).

• At high wages, Income Effect > Substitution Effect. The worker achieves their target income and values leisure more highly, choosing to work fewer hours as pay increases.

List four factors that cause a rightward shift in the Labour Supply curve

• Increase in non-monetary benefits or improved working conditions.

• Lowering barriers to entry (e.g., reduced qualification requirements).

• Positive job perception/prestige.

• Demographic expansion (e.g., net inward migration or population growth).

Define Wage Elasticity of Supply of Labour (WES):

The responsiveness of the quantity of labour supplied to a change in the wage rate:

WES = %CHANGE IN QUANTITY OF LABOUR SUPPLIES / % CHNAGE IN WAGE RATE

Why is the supply of labour for qualified surgeons or lawyers inelastic (WES < 1)

High barriers to entry (lengthy education, expensive training, professional qualifications) so high occupational immobility prevent workers from entering the market quickly when wages rise.

also another example for WES being inelastic (not related to example) is when economy is working near full capacity so higher wage rate leads to little to no extra output as no extra workers are available to take on job

How does the vocational nature of a job affect its WES

Highly vocational jobs (e.g., nursing, teaching) tend to have wage inelastic supply. Workers are driven by non-monetary rewards, making their supply less sensitive to wage adjustments.

How is real-wage (classical) unemployment illustrated on a standard labour market supply and demand diagram?

gap represents excess supply of labour (unemployment)

DEFINE CYLICAL UNEMP/STICKY WAGES

Cyclical unemployment (also called demand-deficient unemployment) is unemployment caused by a downturn in the economic cycle—ie a recession.

• Sticky wages (or "downward wage rigidity") refers to the real-world reality that worker pay does not easily drop when the economy gets bad (due to min wage laws/contracts/low wages make employees -motivated)

How does a labour market shortage (excess demand) look diagrammatically, and what happens to wages?

What is a National Minimum Wage (NMW), and what type of price control is it?

A National Minimum Wage is a statutory minimum pay floor set by the government below which employers cannot legally pay their workers. Diagrammatically, it is a price floor set above the free-market equilibrium wage rate

What determines whether a National Minimum Wage causes a large or small increase in unemployment?

IF WED is INELASTIC: firms cannot easily replace workers or cut output, resulting in minimal job losses

IF WEB is ELASTIC: higher wage costs prompt significant job cuts or automation (Q1 to Q2 is larger)

How can a minimum wage reduce poverty and inequality, and what is the counter-argument?

• Argument: Raises hourly wages for low-income workers, boosting disposable income, living standards, and narrowing the earnings gap.

• Counter-argument: If firms cut hours worked or lay off workers to cover costs, impacted low-income households lose income entirely. It also does not benefit those who are already unemployed.

Explain how a National Minimum Wage can increase worker productivity using Efficiency Wage Theory.

Higher pay boosts worker morale, financial security, and job motivation. Workers work more efficiently and are less likely to leave, reducing employer costs related to recruitment, training, and staff turnover.

Why might a minimum wage NOT cause unemployment?

A monopsony is a market structure with only one single buyer (an employer or a purchasing firm)

Because the monopsonist is the only employer in town, workers have no alternative buyers for their labour. The monopsonist exploits this total lack of competition to suppress wages below fair market levels and restrict total hiring.

monopsonist suppresses wages below competitive market equilibrium. Introducing a statutory wage floor levels the employer's market power, making the marginal cost of hiring constant up to Q3

Define Perfect Labour Market vs. Imperfect Labour Market

• Perfect Labour Market: A theoretical market structure where workers are homogeneous, information is perfect, mobility is complete, and both firms and workers are price takers, resulting in a single uniform wage rate across the industry.

• Imperfect Labour Market: A real-world market where workers have non-identical skills, information is limited, mobility barriers exist, and market power (monopsonies or trade unions) leads to wage differentials.

Define Marginal Revenue Product of Labour MRPL, Wage Elasticity of Demand WED and Wage Elasticity of Supply WES

Marginal Revenue Product of Labour: The additional revenue generated by hiring one extra worker MRPL = MR X MPL

Wage Elasticity of Demand: The responsiveness of the quantity of labour demanded by employers to a change in the wage rate

Wage Elasticity of Supply: The responsiveness of the quantity of labour supplied by workers to a change in the wage rate.

Define Occupational Immobility, Geographical Immobility, and Monopsony Power

Occupational Immobility: Barriers preventing workers from switching between occupations due to a lack of required skills, qualifications, or training.

Geographical Immobility: Barriers preventing workers from relocating for jobs due to housing costs, travel costs, or lack of trasport.

Monopsony Power: Market power held by a single or dominant buyer of labour (employer) to set wages below competitive market levels.

What are the key characteristics distinguishing a Perfect Labour Market from an Imperfect Labour Market

Perfect Market Characteristics: Homogeneous workers, perfect knowledge of wage rates and job openings, complete geographical & occupational mobility, no barriers to entry/exit, and firms/workers are price takers.

Imperfect Market Characteristics: Heterogeneous workers (varying productivity/skills), imperfect information, occupational & geographical mobility barriers, barriers to entry (licences/degrees), and presence of price makers (trade unions and monopsonies).

Define Homogeneous Workers vs. Heterogeneous Workers

• Homogeneous Workers: Workers who possess identical skills, qualifications, productivity, and abilities, making them perfect substitutes for one another in the eyes of employers.

• Heterogeneous Workers: Workers who possess different levels of skills, qualifications, experience, and productivity, making them non-identical and valued differently by employers.

Define Perfect Knowledge vs. Imperfect Information in a labour market

• Perfect Knowledge: A condition where workers are fully aware of all job openings and wage rates, and employers are fully aware of all available candidates' skills and productivity levels.

• Imperfect Information: A real-world market failure where workers lack full knowledge about available jobs/wages and employers lack complete information about workers' true productivity, leading to wage disparities.

Define Geographical Mobility and Occupational Mobility

• Geographical Mobility: The ability and willingness of workers to move from one physical location or region to another to take up employment opportunities.

• Occupational Mobility: The ease with which workers can switch from one type of job or industry to another by gaining new skills or qualifications

Define Barriers to Entry in the context of labour supply

Define Barriers to Entry in the context of labour supply

Define Price Takers vs. Price Makers in a labour market

• Price Takers: Individual buyers (employers) or sellers (workers) who have no market power to influence the wage rate and must accept the wage determined by market supply and demand.

• Price Makers: Employers (monopsonies) or worker groups (trade unions) with sufficient market power to set, negotiate, or influence wage rates above or below competitive equilibrium

What are the 3 main underlying causes of Wage Differentials in labour markets?

• Natural differences in demand and supply of labour (both in terms of wage/employment levels and elasticities).

• Discrimination in the labour market (e.g., based on gender, ethnicity, or age).

• Monopsony power held by dominant employers.

Define a Maximum Wage (Pay Ceiling) and give examples of scenarios where it is applied

• Definition: A legal upper limit set by the government or regulator on wage rates above which employers cannot pay their workers.

• Scenarios / Reasons for Use:

  • Regulating excessive monopoly/monopsony power.

  • Controlling public sector pay bills (e.g., setting pay bands for NHS nurses, doctors, teachers).

  • Capping extreme compensation (e.g., historic wage limits on professional footballers).

  • Controlling wage-push inflation during unusual economic circumstances (e.g., periods of war).

What is the economic impact of setting a maximum wage below the free-market clearing wage, and what are its main disadvantages?

creates an excess demand for labour resulting in a labour shortage

Disadvantages & Evaluation:

• Disincentivises Effort: Lower pay ceilings reduce worker motivation and productivity.

• Brain Drain / Human Capital Flight: Highly skilled professionals may emigrate to countries without wage caps.

• Reduced Government Tax Revenues: Capping top pay lowers high-rate income tax receipts.

What is a Trade Union, and how does it use collective bargaining power to support its members?

• Definition: An organized association of workers in a trade or profession formed to protect and further their rights and interests.

• Key Roles & Objectives:

  • Protect and improve real wages and living standards.

  • Safeguard workers against unfair dismissal and uphold legal employment rights.

  • Improve workplace safety, health regulations, and work-life balance.

  • Secure better training opportunities and protect pension rights.

Analyze the theoretical impact of union-negotiated wages on Workers and Firms

• Impact on Workers: Union bargains a wage above market equilibrium raising worker incomes and reducing income inequality. However, if demand is wage-elastic, employment falls from E1 TO E2, creating potential job losses/unemployment.

• Impact on Firms: Higher wages raise total cost of production (COP), compressing profit margins. In response, firms may reduce headcount or substitute labor with capital and automation.

What factors explain the historical decline in Trade Union Density?

Tighter Anti-Union Legislation: Stricter laws limiting right-to-strike and picketing actions reduced union bargaining strength.

• How can workplace discrimination be tackled through Legislation vs. Free Market Mechanisms?

• 
  

• UK acts like the Equal Pay Act (1970), Sex Discrimination Act (1975), and Equality Act (2010) legally prohibit discrimination based on gender, ethnicity, age, or disability.

• Free Market Theory: Discriminatory employers restrict their hiring pool to preferred groups, driving up their own wage costs. Non-discriminatory rivals hire undervalued, skilled minority workers at lower wage costs, undercutting discriminatory firms and using market forces to equalize wages over time.

Explain how an increase in the National Minimum Wage (NMW) impacts Economic Growth, including evaluation points.

Analysis (Positive Impact): Low-paid workers have a high Marginal Propensity to Consume, Analysis (Positive Impact): Low-paid workers have a high Marginal Propensity to Consume (as they spend majority of income on essentials) shifting Aggregate Demand right and inc RGDP

Evaluation (Negative Impact): Higher labor costs may force firms to cut jobs, increasing unemployment, which lowers overall disposable income and suppresses consumption

Explain how an increase in the National Minimum Wage (NMW) impacts Inflation, including evaluation points

Demand-Pull Inflation: Increased consumer spending shifts AD to the right, driving up price levels

Cost-Push Inflation: Higher wage bills raise production costs for firms, forcing them to increase product prices to maintain profit margins

Evaluation: If wage increases are substantial, firms may invest in capital and technology, boosting long-run productivity and lowering unit costs to offset cost-push inflationary pressures over time

Define Labour Demand and identify key factors that increase Geographical Mobility

• Labour Demand: The quantity of labour firms are willing and able to hire at a given wage rate over a given period of time.

• Factors Increasing Geographical Mobility:

  • Better transport infrastructure.

  • More affordable housing.

  • Reduced regional price/cost-of-living disparities

Define Labour Market Flexibility, Wage Flexibility, and Non-Wage Flexibility.

• Labour Market Flexibility: The degree to which labour markets adjust to new market equilibria via the price mechanism (wage mechanism).

• Wage Flexibility: How easily nominal/real wages can adjust up or down in response to shifts in supply or demand (avoiding wage stickiness/rigidity).

• Non-Wage Flexibility: The ease with which employment levels, working hours, job roles, and skills can adapt to changing economic conditions (e.g., flexible contracts, retraining).

How do Trade Unions and Government Regulations impact labour market flexibility?

• Trade Unions: Reduce wage flexibility by resisting pay cuts (making wages "sticky" downwards). Reduce non-wage flexibility by limiting a firm's ability to easily alter working hours or fire staff.

• Government Regulations:

  • Minimum/Maximum Wages: Restrict price movement and limit wage flexibility.

  • Employment Protection Laws: Make hiring and firing more costly, leading to inelastic Wage Elasticity of Demand (WED);If the cost of firing a worker exceeds the cost of paying their higher wage in the short run, the firm will simply keep the worker. Because employment barely falls when wages rise, the demand for labor responds weakly—making WED inelastic.

  • Training Requirements/Licensing: Create barriers to entry, making labour supply inelastic (WES).

Explain Occupational Immobility and Geographical Immobility, including their causes and impacts on supply responsiveness WES

• Occupational Immobility:

  • Definition: The inability of labour to move between different types of occupations.

  • Cause: Lack of relevant skills, qualifications, or training.

  • Impact: Reduces non-wage flexibility; labour supply cannot quickly respond to changing wage rates or demand shifts ($WES$ becomes inelastic).

• Geographical Immobility:

  • Definition: The inability of labour to move between different geographical regions.

  • Cause: High housing/rent costs, travel costs, and family or cultural ties.

  • Impact: Limits spatial reallocation of labour, causing regional skill shortages.

• How does Globalisation affect labour market flexibility?

Migration: Open migration policies reduce restrictions, allowing workers to move across borders easily to fill vacancies. This increases supply responsiveness (WES +elastic)

Outsourcing: Firms can shift operations or production overseas to countries with lower costs or more adaptable workforces, increasing operational flexibility.

• What are the Advantages (Analysis) and Disadvantages (Evaluation) of a highly flexible labour market?

Advantages (Analysis):

• Micro: Lower production costs for firms; improves efficiency and profit margins.

• Macro: Reduces structural unemployment (making it easier for workers and businesses to adapt when jobs change or move to new industries), increases international competitiveness, and lowers cost-push inflation

Disadvantages (Evaluation):

• Job Insecurity: Increased prevalence of zero-hour or temporary contracts reduces worker financial security.

• Lower Investment: Workers may receive less employer-funded training if job turnover is high.

• Income Inequality: Weakening unions and deregulation can drive down wages for low-skilled workers

Structural unemployment

happens when there is a mismatch between the skills workers have and the skills jobs require, often due to technological advances or the decline of old manufacturing sectors

Define Economic Inactivity and identify who is classified as inactive versus unemployed.

• Definition: Working-age individuals (aged 16–64) who are neither in employment nor actively seeking/available for work.

• Examples of Inactive Individuals: Full-time students, stay-at-home parents/carers, individuals with long-term illness/disability, and early retirees.

• Key Distinction: Unemployed individuals are actively seeking work and available to start; inactive individuals are not looking or unavailable.

What is the difference between a NEET and an Unemployed Youth

NEET (Not in Education, Employment, or Training): Includes young people (aged 16–24) who are economically inactive plus those who are unemployed.

Unemployed Youth: Young people aged 16–24 who are actively searching for work and available to start, but cannot find a job.

Analyze the macroeconomic and microeconomic impacts of Rising Inactivity

Labour Markets & Growth: Reduces effective labor supply, leading to skill shortages, lower potential output LRAS left so RGDP falls

• Hysteresis & Confidence: Long periods of inactivity lead to skill decay, reduced employability, and loss of workplace confidence.

• Government Finances: Decreases income tax and NI receipts while raising welfare expenditure, worsening the fiscal deficit.

• Inflationary Pressures: Labour shortages push up wages, driving cost-push inflation.

are the four primary causes of Youth Unemployment

Education & Skills Mismatch: Strong correlation with poor GCSE/qualifications; lack of vocational skills required by employers

Lower Perceived MRP; Young workers lack experience, making their perceived Marginal Revenue Product lower relative to entry wages

Lack of Entry-Level/Graduate Jobs: High competition leaves qualified school leavers or graduates overqualified or unhired

Contractual Vulnerability & Frictional Delay: Flexible/temporary contracts mean young workers are "first to be fired" during downturns, plus time lost during transitions from school to work

• Outline effective policies to tackle Inactivity and Youth Unemployment, with evaluation.

• 
  

• Supply-Side Policies:

  • Subsidised Training/Apprenticeships: Boosts skills, increases $MRP$, and tackles occupational immobility.

  • Healthcare/NHS Reforms: Reduces long-term sickness inactivity, re-engaging workers into the labor force.

  • Childcare Subsidies: Enables stay-at-home parents to re-enter employment.

• Fiscal/Demand-Side Policies: Job creation schemes or wage subsidies for employers hiring young workers.

• Evaluation: High opportunity cost for government budgets; supply-side policies take time to yield results.

Explain how employer discrimination against a worker group affects Wage Rates and Employment Levels using demand and supply analysis.

Impact on Disfavoured Group:

• Employers downgrade perceived MRP shifting labor demand left MRP0 → MRPdis)

• Result: Wage rates drop and employment falls

Impact on Favoured Group:

• Employers substitute towards favoured workers, shifting labor demand (MRP0 → MRPf)

• wage rises and employment increases, WAGE GAP CREATED
