The cost of labour is the largest cost factor in the economy. Changes in the cost of labour therefore have a significant impact on cost and price trends in the economy. The cost of labour depends on the wages and salaries paid to workers and on the productivity of labour. Productivity (or quality) of labour is an important determinant of the cost of labour. Wages and salaries do not only represent costs. They are also an important demand factor as they are the main source of household income and they therefore influence the demand for goods and services. Creation of jobs arguably the most important objective of economic policy.

For example, if the demand for labour decreases, the impact will depend on the elasticity of the supply of labour. The more inelastic the supply of labour, the greater the impact on the wage rate and the smaller the impact on the level of employment will be. Likewise, the impact of a change in the supply of labour will depend on the elasticity of the demand for labour.
