1derived demand
when a factor of production is demanded for its use in producing final goods and services
2demand for labour
the amount that firms are willing to pay for a certain amount of workers
3marginal physical product
the extra goods or sevices one more worker can produce
4marginal revenue
the extra revenue generated from selling one good or service
5marginal revenue product (MRP) =
marginal physical product x marginal revenue
64 factors that cause the demand for labour curve to shift
price of final product, changes in demand for the final product, changes to labour productivity, changes in the price of capital
7Why does the MRP curve slope downwards
the law of diminishing marginal returns
8wage elasticity of demand for labour
the responsiveness of the quantity of demand for labour to a change in the wage rate
9elasticity of demand for labour =
%change in QD labour / %change in wage
10if demand for labour is inelastic
a change in the wage does not have much impact on the number of workers employed
11if demand for labour is elastic
a change in the wage has a large impact on the number of workers employed
124 factors that determine how elastic demand for labour is
ease of substitution of capital for labour, elasticity of demand for the final product, proportion of labour to total cost, time span
13supply of labour
the number of hours or number of workers able and willing to work at a given wage rate
14Labour supply in the UK
33.8 million
15Unemployment rate in the UK
1.4 million people (4.3%)
16substitution effect
as wages rise, the opportunity cost of leasure increseses, this causes workers to work longer hours, work is more rewarding relative to leisure
17income effect
as wages rise, the demand for leisure rises strongly (leisure is a luxury good), this causes workers to work fewer hours so they can enjoy more leisure time
18for people on low incomes, the … effect is more dominant
substitution
19for people on high incomes, the … is more dominant
income
20shape of the supply of labour curve
backwards-bending
21supply of labour graph
hourly wage against number of hours worked
22implications of the backwards bending curve for policy
raising the minimum wage, cutting the higher rate of income tax
235 economy-wide factors affecting the supply of labour
migration, levels of out of work benefits, skill levels, demographic changes (ageing population), cultutral change (role of women)
244 job-specific monetary factors affecting the supply of labour
bonus, pension, overtime, wage level in competing jobs
255 job-specific non-monetary factors affecting the supply of labour
perks (free lunch/travel), location, colleagues, job satisfaction, security
26wage elasticity of supply
the responsiveness of the supply of labour to a change in the wage rate
27wage elasticity of supply =
% change in QS / % change in wage
28the supply of labour is inelastic if
when wages change, the supply of labour changes little
29the supply of labour is elastic if
when wages change, the supply of labour changes a lot
304 factors influencing the elasticty of the supply of labour
qualification and training requirements, vocational nature of the job, labour mobility, time span
314 assumptions of a competitive labour market
workers are homogenous, there are many buyers of labour (firms) and many sellers (workers), workers are mobile, there is perfect information about wages, vacancies
32firms are wage takers means that wages
are set at the industry level as firms have no market power
333 ways in which labour markets are not competitive
trade unions, monopsony, immobility
34trade unions
an organisation or group of workers that advocate for workers rights
35impact of trade unions depens on 4 factors
elasticity of demand/supply of labour, productivity of labour force, power of the threat of the strike, agreement for fewer hours rather than fewer jobs
36labour market monopsony
when there is only one major employer of a particular kind of labour
37strong trade unions in a competitive labour market are likely to … wages and … employment
raise, lower
38monopsony employers in the absence of a union are likely to … wages and … employment
lower, lower
39where a monopsony is present, a strong trade union can counter act it to … wages and … employment
raise, raise
40geographically immobile
workers that are unwilling or unable to move from one area to another to take up job opportunties
41occupationally immobile
workers that are unwilling or unable to retrain to take up job opportunitites in a different sector of the economy
424 reason for geographic immobility
attachment to family and friends, poor transport links, cost or availability of housing, language or cultural barriers
434 reasons for occupational immobility
inadequate access to education or training, poor qualifications from school, attachement to a particular type of work (vocation), lengthy or costly training routes into new professions
45National Living Wage

47Unfilled job vacancies
over 1 million
48public sector pay increases were previously capped at

522 uk policies to deal with labour immobility

533 good longstanding features of the UK labour market
high employment, low unemployment, flexible (easy to hire and fire workers)
541 good recent feature of the UK labour market
sharply rising nominal wages
554 bad longstanding features of the UK labour market
low productivity growth, high inequality, in-work poverty, insecurity (zero-hours contracts)
562 bad recent features of the UK labour market
labour shortages, falling real wages
