Plain-language explanation.
Labour economics studies how labour markets work — wage determination, employment, unemployment, discrimination, human capital investment, and the effects of policy. It is directly relevant to living standards, inequality, and the future of work.
Core concepts and standard treatment.
Core labour economics covers labour supply and demand (labour supply — income-leisure trade-off — individual labour supply curve — backward bending at high wages — substitution and income effects; household labour supply — Mincer — participation decision — reservation wage; labour demand — marginal revenue product of labour — MRPL = MR × MPL; demand for labour as derived demand; labour market equilibrium — wage and employment determination; compensating wage differentials — Rosen — Smith), human capital theory (Becker — investment in human capital — education and training — returns to education — Mincer equation — log wage = a + b(schooling) + c(experience) + d(experience2); private vs social returns to education — externalities; signalling vs human capital — Arrow vs Becker; general vs specific training — Becker — who pays for training; on-the-job training — apprenticeships — Levy-Murnane), and wage inequality and discrimination (wage inequality — skill premium — computer capital substitution — Katz and Murphy; gender pay gap — occupational segregation vs discrimination — audit studies — Goldin; discrimination theory — Becker — taste for discrimination — employer discrimination reduces profit; statistical discrimination — Arrow Phelps — using group characteristics as proxy; monopsony in labour markets — Card and Krueger; union wage premium — insider-outsider models).
Deeper theory, debates and edge cases.
Advanced labour economics covers minimum wage economics (Card and Krueger 1994 — New Jersey fast food — first major RCT — employment did not fall; Dube meta-analysis — minimum wage elasticity near zero for low-wage workers — monopsony reconciles; Seattle minimum wage study — UW — hours reduction — business closure — Jardim; Autor Dorn — routine biased technological change — hollowing out of middle-skill jobs; National Living Wage UK — LPC — Low Pay Commission — annual review), the gig economy and platform work (Krueger and Katz — fissured workplace; Uber and Lyft driver earnings — Hall and Krueger; worker classification — employee vs independent contractor — Blythe Supreme Court UK; OECD Gig economy — benefits cliff; Taylor Review of Modern Working Practices 2017; Trade Union Act 2016; Worker Protection Act 2023), and immigration economics (immigration and wages — Borjas — wage elasticity -0.3 to -0.4 — Card — cities study — near-zero effects; immigration surplus — welfare gains to destination country; fiscal impact of immigration — Migration Advisory Committee MAC; ageing population and immigration; high-skilled migration — brain drain vs brain gain — co-development; UK immigration after Brexit — points-based system — Shortage Occupation List — SOL).
How it is applied in practice.
At the labour economist and policy adviser level, practitioners contribute to Journal of Labour Economics and Economic Journal; advise on UK employment policy (BEIS and DWP — National Living Wage — LPC — Low Pay Commission annual recommendations; Work Capability Assessment reform — PIP — productivity and disability employment gap; Good Work Plan; employment tribunals — ET1 ET3; Equality Act 2010 — s.4 protected characteristics in employment — EqA section 26 harassment; Employment Rights Bill 2024 — day one rights — zero hours contract reform); lead labour market research (Resolution Foundation — living standards; Institute for Fiscal Studies labour market — Carl Emmerson; NIESR labour market analysis; CIPD Good Work Index; ONS LFS Labour Force Survey — claimant count — ILO unemployment); design workforce programmes (Kickstart scheme evaluation; Apprenticeship Levy and levy reform — IfATE Institute for Apprenticeships; bootcamps — Digital Skills Bootcamps; DfE Skills England); and advise on future of work (IPPR Commission on Economic Justice; WEF Future of Jobs report; AI and employment — Acemoglu and Restrepo — tasks and automation — complementarities vs displacement; robot adoption — Autor Salomons; platform regulation — EU Platform Work Directive 2024).
