This topic looks at why wages differ between workers and jobs. Questions cover compensating differentials, such as higher pay for dangerous work in coal mines, efficiency wages and other reasons some workers earn above the equilibrium wage. You will also meet the substitution and scale effects of a rise in labour costs, how trade unions can raise wages by restricting labour supply, why a wage gap alone does not prove discrimination, and how land and capital are allocated between uses. These ideas appear in labour and development economics papers for civil service and university exams.

Human capital is the stock of knowledge, skills, health and experience that makes a worker productive. Investment in education and training raises human capital, which usually leads to higher productivity and earnings. It helps explain why workers with similar backgrounds can still earn different wages.
A compensating wage differential is extra pay that makes up for unpleasant, risky or difficult features of a job. For example, a coal miner may earn more than a similarly skilled worker in a safer job. The higher wage compensates for the danger and discomfort rather than for greater skill.
