Labor and Demographic Economics

Labor and demographic economics studies the markets for work — the supply and demand for labour, wages and employment, human capital, and the economics of population, the family, and migration.

Scope

The field (JEL category J) covers labour supply and demand, wage determination, human capital and education, unemployment, discrimination, unions and labour-market institutions, and the demographic economics of fertility, the family, and migration.

Sub-topics

• General
• Demographic Economics
• Demand and Supply of Labor
• Wages, Compensation, and Labor Costs
• Particular Labor Markets
• Labor–Management Relations, Trade Unions, and Collective Bargaining
• Mobility, Unemployment, Vacancies, and Immigrant Workers
• Labor Discrimination
• Labor Standards: National and International

Core questions

• What determines wages and employment?
• How do people decide how much to work and how much to invest in skills?
• What explains wage inequality and discrimination?
• How do institutions (unions, minimum wages) affect labour markets?
• How do family and population decisions interact with the economy?

Key concepts

• Labour supply and demand
• Human capital
• The Mincer earnings function
• Wage differentials
• Unemployment
• Discrimination
• Labour-market institutions
• Demographic economics

Key theories

Human capital theory

Becker treated education and training as investment in productive 'human capital', and Mincer's earnings function linked earnings to schooling and experience.

Dual-economy / unlimited labour supply

Lewis modelled development as the absorption of surplus labour from a traditional sector into a modern one, foundational for labour and development economics.

History

Labour economics moved from institutional analysis to a neoclassical, microfounded field with the human-capital revolution (Becker, Mincer, Schultz) of the 1960s-70s. Lewis's dual-economy model linked it to development. Since the 1990s the field has been reshaped by the 'credibility revolution' in causal inference, with quasi-experimental studies of education, minimum wages, immigration, and discrimination.

Debates

Do minimum wages reduce employment?

The textbook competitive prediction of job losses has been challenged by quasi-experimental evidence, reviving monopsony models of the labour market.

Human capital versus signalling

Whether education raises productivity (human capital) or mainly signals pre-existing ability remains debated.

Frequently asked questions

What is human capital?

The stock of knowledge, skills, and health embodied in people that raises their productivity; education and training are investments in it.

Why is demography part of this field?

Decisions about fertility, marriage, and migration are economic choices that shape labour supply and are analysed with the same tools, so the JEL groups labour and demographic economics together.
