4.1.6 The labour market Flashcards
(36 cards)
Explain the Demand for Labour + Marginal Revenue Product Theory (MRP).
- Firms demand labour, individuals supply it.
- D for L = S for L (equilibrium WR + equilibrium Q of workers).
- Demand curve for L shows how many workers firms will hire at any given wage rate over a given period of time.
- Demand for L is a derived D- comes from D for goods + services.
- Firms base D decisions for L on marginal revenue product (MRP)
- Marginal Revenue Product (MRP): extra revenue generated when an additional worker is hired.
- MRP = MPP (Marginal Physical Product= P x MP) x MR.
- Inverse relationship between W + Q of workers.
Define the Demand For Labour.
How many workers an employer is willing + able to hire at a given wage rate in a given time period.
Explain the Labour Demand Curve (Market).
- Inverse relationship between WR + Q of workers.
- In SR due to law of diminishing returns.
- In LR at higher WR firms think L isn’t as cost effective + its more cost effective to employ cheaper capital relative to L. (Q of workers decreases at higher WR.)- down to substitutability between L + capital in LR.
- W go up- contraction of LD (Q3) (fall in Q of workers).
- W go down- extension of LD (Q2) (increase in Q of workers) Firms more willing + able to employ at this WR.
State + explain the criticisms of MRP Theory.
- Productivity: difficult to measure in certain industries (e.g. teaching profession- output teachers produce isn’t marketed- no P of it).
- Teamwork Makes It Diff To Measure Individual Productivity: if individuals are working in teams- producing output as a team.
- Self-Employed: assume workers are payed according to their MRP, but self-employed don’t pay themselves according to their MRP- distorts/goes against theory that workers are payed according to MRP.
- Imperfect Labour Markets: MRP theory assumes labour market is perfectly competitive. May be trade unions bargaining for higher W- may have nothing to do with MRP of workers.
State + explain the Labour Demand Curve Shifts.
LD curve shifts irrespective of wage.
* Price: change in final P of product L is making (e.g. if P of product goes up, MRP increases- D curve shifts right).
* Demand: Change in D for final product: if increases, LD increases (as its a derived demand)- shifts right.
* Productivity: change in L productivity: if increases, increases LD- shifts right.
* Capital: change in P of capital: in LR all FOPS are variable (firm can either hire more workers or hire more capital- substitutable) if P for capital decreases, maybe LD will decrease. Tech has potential to replace human workers (e.g. robots can perform tasks such as welding + surgery, AI being used to develop self-driving cars.)
State + explain the determinants of the elasticity of demand for labour.
- Substitutability of Capital For L: more substitutable capital is for labour, the more W elastic LD will be. If W rise, firms can reduce the number of workers + employ more capital. If substitutable, D for L is elastic, vice versa.
- Elasticity Of D For Final Product: if inelastic + W go up, firms wont respond by cutting workforce significantly/reducing LD because they can pass on higher C via higher P (thus LD is inelastic).
- Cost of Labour As % Of TC: greater LC is as % of TC- more W elastic LD will be.
- Time Period: in LR all FOPS become variable- much more easier to bring in capital- LD becomes more W elastic in LR.
Define the elasticity of labour demand.
- Measures responsiveness of labour demanded given a change in wage rate.
Define the Labour Supply.
- Measures hours that people are willing + able to work at a given wage rate.
Explain the income effect + the substitution effect.
Individuals have to make a key choice between work + leisure (i.e. how to spend time)- one is opportunity cost of another.
* Income Effect: rise in income as wages rise (incentive to work more- positive income effect) but with potential of individuals reaching a target income (i.e. could potentially work less to reach target income- negative income effect). Thus can be positive or negative.
* Substitution Effect: as wages rise, opportunity cost of leisure time increases always providing an incentive to work.
State + explain the Labour Supply Curve Shifts.
- Wage On Offer In Substitute Occupations: if really high, a lot of workers in occupation will leave + work in other profession where W are hire- shifts S curve left.
- Barriers To Entry: (e.g. minimum entry requirements, skills, qualifications, e.t.c.) the stricter requirements become, less SL there’ll be in that industry- shifts S left. (e.g. medical industry- becoming a doctor)
- Non-Monetary Characteristics Of Job: (e.g. health-care benefits, education benefits, good pension plan, working hours, e.t.c.) More non-monetary benefits, more LS will shift right.
- Improving Occupational Mobility Of Labour: shifts S right- if more workers gain qualifications/skills to enter a given profession, increases S in that profession.
- Over-Time: ability of workers to choose overtime- increases SL- shifts S right.
- Size Of Working Population
- Value Of Leisure Time: if increases, SL shifts left.
Define the elasticity of labour supply.
- Measures responsiveness of labour supplied given a change in wage rate, in a given time period.
State + explain the determinants of the elasticity of supply for labour.
- Nature Of Skills Required In Job: greater skills / more specific skills required (i.e. harder it is for those not already in profession to take jobs in profession) more inelastic supply tends to be.
- Length Of Training Period: longer length period is, less likely those outside profession are going to want to take jobs- even if WR goes up. Makes labour supply very wage inelastic.
- Vocation: (e.g. professions like teaching, nursing) all have vocational elements. Don’t just do the job just for monetary benefit, thus less responsive to changes in W (wage inelastic), in comparison to people in other professions where vocational elements don’t exist as much.
- Time: in SR- immediately after W change don’t see much impact on Q supplied of L. Due to a lot of people being required to give notice, take time to adapt to W changes, e.t.c.) Tends to be quite inelastic. However, in LR tends to be more elastic.
State + explain the characteristics of a perfectly competitive labour market.
- Large Number of Potential Workers + Employers: lots of firms willing + able to hire workers + huge number of workers looking for jobs.
- Labour Is Homogenous: assume there’s no differences in skills + qualifications between workers. Assume all workers have skills + qualifications required for any job- labour is perfectly mobile.
- Perfect Information: of market conditions- for firms + workers. For workers, know going WR + for firms they know skills + productivity of all workers.
- Firms Are Wage Takers: no control over W they can offer workers. Instead take it from market (where D = S). No incentive for firms to offer a higher WR than that, as all workers are homogenous- thus would C them more than MR would bring in. No incentive to offer workers WR below market because workers will go to a different firm which offers the WR- which is higher.
- No Barriers To Entry/Exit: for workers- assume there’s no extra skills/qualifications needed to take job. No barriers to exit either- free to leave the job- no need to hand in notice.
Explain wage determination in a perfectly competitive labour market.
2 Key Assumptions Made:
1) Firms operating in a perfectly competitive L market.
2) Firms operating in perfectly competitive product market. (Firms are P takers + W takers).
* Firms assumed to be in SR- experiencing law of diminishing marginal returns
* As number of workers increases, figures initially rise + then start to fall.
* Firms looking to maximise revenue from workers will make efficient employment decisions + decided to hire workers up until MRP = W (MCL).
State + explain the labour market imperfections.
Tell us why W differentials occur.
* Labour isn’t homogenous: all workers are different + have different MRPs, therefore W they get can be different. Might be some professions where workers aren’t suitable to take that job- thus supply of L can be different in different markets, affecting W rage- allowing for W differentials. Discrimination- different workers paid different W.
* Non-Monetary Considerations: in real-world, more than just W which depends on whether individual will take job. Consider non-monetary features of job (e.g. pension plan, company car, holidays available, potential for promotion, overtime, flexibility of working hours, e.t.c.). Therefore if non-monetary considerations are fantastic- expected there’d be a large amount of workers in industry- driving down W. If working conditions aren’t as good, there’d be a lack of S in those industries- higher W (compensating W differentials).
* Labour Isn’t Perfectly Mobile: often isn’t occupationally mobile- not all workers have same skills/qualifications/productivity (e.g. certain professions where qualifications required exclude a lot of workers). Restricts LS, pushing up W significantly. Might be regional variances in W- might persist due to geographical immobility of L- workers may not want to move to take a job, even if W is higher. Thus, LS is restricted + W can stay different for persistent periods of time. Lack of perfect knowledge- individuals may not know what W are in diff positions.
* Trade Unions + Supply Restrictions: TU bargain for higher W- larger the TU, more bargaining power to ask for higher W + distort perfectly competitive market outcomes + push up W. In comparison to industries where TU don’t exist- leads to W differentials.
* Monopsonies + W Setting Ability: 1 dominant employer in given profession that employs large chunk of workers in industry- have W setting power- may use to drive down W. Thus, in that industry, W may be lower, in comparison to other industries where there aren’t monopsonies existing. Big reason for W differentials existing.
Define a monopsony.
- Sole employer of labour in a given industry.
- Example: teachers + nurses in UK- employed by state- dominant employer.
State + explain the characteristics of a monopsony.
- Wage Makers: set wages- have significant buying power.
- Maximise Revenue From Workers: by hiring workers up until MRP = MCL
- Employment: employ workers where MCL = MRP. Significantly reduced in comparison to competitive markets.
- Wages: WM. Significantly reduced in comparison to competitive markets.
- Lower W compared to MRP- greater monopsony power that exists in that market.
- Very inefficient- distorting efficient L market outcomes.
State + explain the interventions reducing monopsony power of employers.
- Minimum Wage Laws: setting a legally-enforced pay floor in labour market. When enforced, can help to ensure that workers are paid a fair wage, even in industries where there’s monopsony power.
- Regulation + Laws: (e.g. allowing trade union representation, equal pay legislation, employment protection laws, e.t.c.)
State + explain how monopsony power can lead to labour market failures.
- Lower Wages: in monopsony, employer can set wages below competitive equilibrium level because they are primary buyers of labour. Can result in lower W for workers, leads to underpayment + reduced standard of living for employees.
- Reduced Unemployment: monopolistic employers may also choose to hire fewer workers than they would in a competitive labour market. Results in higher levels of unemployment/underemployment.
- Diminished Job Quality: monopolistic employers may provide suboptimal working conditions, fewer benefits, + less job security. Negatively impacts well-being + job satisfaction of workers.
- Economic Inequality: monopsony power can exacerbate income inequality as concentrates bargaining power with employers, leaving workers with less ability to negotiate higher W. Leads to increase in working poverty + rising claims to welfare state.
Define a Trade Union.
Trade Union: organisation with lots of different workers, that bargain especially for higher W, but also for better working conditions (collective bargaining).
* Assume ‘closed shop’ TU- other TU don’t exist, 1 TU has all workers behind it- TU becomes monopoly supplier of L.
* TU controls SL at given WR.
* 2022: 6.25 million people registered as members of TU.
State + explain how wages + employment are affected by Trade Unions in competitive labour markets.
- Wages: now higher- increased compared to competitive outcomes.
- Employment: D for workers has fallen (QL to QTU). WR of WTU causes unemployment (excess S of workers.) Inefficient outcome.
- Raising C for firms.
Evaluate the use of Trade Unions.
- TU In A Monopsony Labour Market: may make things better- higher W- improve W by moving them closer to competitive outcomes + increasing employment.
- Strength Of TU Power: in real-world ‘closed-shop’ TUs are illegal, so TUS may not have same strength assumed. Measure union density- proportion of workforce in given profession that are part of a given TU- greater % greater TU power- greater bargaining power + control of LS.
- Success Determined By Union Mark Up: difference in W- between what workers are getting who are part of TU + workers in a similar profession who aren’t in TU- bigger difference- bigger success of TU.
- Real-World Evidence Proves Limited Power Of TUS: strict legislation (since 1970s) against TUs- closed shop TU now illegal- significantly reduces power of each TU, limits union density as workers now have to be spread around diff TUs. Legislation reducing how easy it is so strike- only happen if at least 75% members in TU agree to strike, only strike against own employer. Restructuring of UK economy- limited power of TU- UK moved away from manufacturing + heavy industry related jobs towards more service sector jobs- lots of diff employers- makes organising TU activity difficult. Part-time work much more prevalent- hard to organise TU activity around it. Since globalisations taken over- competitive pressures increased dramatically- firms now have more power to reject whatever TU are demanding.
- Over last 2 years, there’s been increases in industrial action by TU (e.g. rail, nursing, teaching, ambulance, e.t.c.)
Explain why Trade Union membership has declined in the UK.
- Union membership peaked in 1970s when over 13 million workers were members of TUs.
- Restructuring of economy: UK moved away from manufacturing + heavy industry related jobs towards more service sector jobs- lots of diff employers- makes organising TU activity difficult. Part-time work much more prevalent- hard to organise TU activity around it.
- Legislation: strict legislation (since 1970s) against TUs- closed shop TU now illegal- significantly reduces power of each TU, limits union density as workers now have to be spread around diff TUs. Legislation reducing how easy it is so strike- only happen if at least 75% members in TU agree to strike, only strike against own employer.
- Globalisation + FDI: foreign owned firms less accommodating of unions. Since globalisations taken over- competitive pressures increased dramatically- firms now have more power to reject whatever TU are demanding.
- Example: percentage of employees who are members of union in UK fell from 32% in 1995 to 23% in 2018.
State + explain how wages + employment are affected by Trade Unions in monopsony labour markets.
• Wages: increased from WM to WTU- closer to competitive market outcomes. Monopsonist has to take WTU- assuming they have strong bargaining power + union density. Thus, S curve becomes horizontal- monopsonist becomes W taker (also ACL + MCL curve)- each worker being paid same W of WTU- thus MCL curve now constant. Beyond the horizontal line, if monopsonist wants to employ more workers, need to increase W to attract workers into industry- thus S curve reverts back to original S curve (STU = ACL). As soon as monopsonist increases W beyond horizontal line to attract new workers- increasing W for everyone. Thus, MCL reverts back to original. Vertical discontinuity in TUMCL curve. Monopsonist still hires workers up until MRP = MCL (now QTU). Maximises profits monopsonist brings in from hiring workers.
• Employment: increasing from QM to QTU- closer to competitive L market outcomes.
• Improves efficiency in monopsony controlled L markets- bargains for hire W + increases employment.
