Reasons for differences in wages: government policy

Microeconomic Decision‑Makers – Workers

1️⃣ What are wages?

Wages are the money workers receive in return for their labour. Think of it as a “price tag” on the effort you put into a job. The amount you earn can be written as \$w\$.

2️⃣ Why do wages differ? Government policy

Governments use policies to influence how much workers earn. Below are the main tools:

  • 📈 Minimum Wage – sets a floor below which wages cannot fall.

  • 📉 Taxation – progressive taxes can reduce take‑home pay, while tax credits can increase net wages.

  • 💰 Subsidies & Grants – direct payments to workers or employers can raise wages.

  • 🏦 Regulation of Labour Markets – e.g., collective bargaining rights, labour‑rights enforcement.

📊 Example: Minimum Wage Impact

PolicyEffect on WagesReal‑World Example
Increase Minimum Wage to £8.10/hour↑ \$w\$ for low‑skill workersUK 2024: £8.10 → many retail workers earn more
Introduce a tax credit for low‑income earners↑ net \$w\$ after taxUS 2023: Earned Income Tax Credit (EITC)
Subsidise apprenticeships↑ wages for trainees + employer cost‑shareGermany: Dual system apprenticeships

⚖️ Analogy: The Wage Scale

Imagine a balance scale. The left side is government policy and the right side is workers’ wages. If the government adds a heavier weight (e.g., a higher minimum wage), the scale tips and wages rise. If the government removes a weight (e.g., cuts subsidies), the scale tips the other way and wages fall.

💡 Exam Tip Box

Exam Tip: When answering questions about wage differences, always:

  1. Identify the policy (minimum wage, tax, subsidy).

  2. Explain the mechanism (e.g., “minimum wage sets a floor, so wages cannot fall below this level”).

  3. Give a real‑world example to support your answer.
