Microeconomic Decision-Makers – Workers

Workers are the primary suppliers of labour in the market. Their decisions on how much to work, where to work, and what skills to develop are influenced by a range of economic and social factors. In this section we examine the key reasons that determine wages and how discrimination, particularly gender discrimination, can alter the wage outcomes for male and female workers.

1. Determinants of Wages

  • Supply and Demand for Labour

    Wages are the price of labour. In a competitive market, the wage rate is set where the quantity of labour supplied equals the quantity demanded.

  • Skill and Human Capital

    Education, training, and experience increase a worker’s productivity, leading to higher wages. The relationship can be expressed as

    Wage = \$α + β \times \text{Human Capital} + ε\$

  • Productivity

    Wages tend to rise with the productivity of the worker. If a worker contributes more output per hour, the employer is willing to pay more.

  • Union Bargaining Power

    Collective bargaining can raise wages above the competitive equilibrium, especially in industries with strong unions.

  • Cost of Living and Regional Factors

    Wages vary across regions to reflect differences in living costs and local demand for labour.

  • Legal and Institutional Constraints

    Minimum wage laws, overtime regulations, and labour standards set floor levels for wages.

2. Discrimination and Wage Inequality

Discrimination occurs when employers treat workers differently based on non‑productive characteristics such as gender, race, or age. This can lead to systematic wage gaps even when workers have comparable skills and experience.

  1. Gender Discrimination

    Women often receive lower wages than men for similar work. This can be due to direct bias, occupational segregation, or differences in work experience caused by career interruptions.

  2. Racial and Ethnic Discrimination

    Workers from minority groups may face wage penalties if employers hold prejudiced beliefs about their productivity.

  3. Age Discrimination

    Older workers may be paid less due to stereotypes about adaptability or productivity.

3. Illustrative Example: Gender Wage Gap

Consider a simplified labour market where male and female workers possess identical skills and experience. In the absence of discrimination, the wage would be the same for both groups. However, if employers discriminate against women, the wage for women may be lower.

GroupSkill LevelExperience (years)Observed Wage (£/hour)Expected Wage (£/hour)Wage Gap (£/hour)
MaleHigh5£15.00£15.00£0.00
FemaleHigh5£13.50£15.00£1.50

In this example, the wage gap of £1.50 per hour reflects the effect of discrimination. The expected wage is calculated using a standard wage equation that incorporates skill and experience.

4. Policy Measures to Reduce Wage Discrimination

  • Equal Pay Legislation

    Enforces parity in pay for equal work.

  • Transparency Initiatives

    Requiring firms to publish wage data by gender or ethnicity.

  • Anti‑Discrimination Training

    Educates employers and employees about unconscious bias.

  • Support for Work‑Life Balance

    Paid parental leave and flexible working arrangements reduce career interruptions.
