The Supply of Labour (Cambridge (CIE) A Level Economics): Revision Note

An agreed hourly rate or fixed annual sum paid for labour

• The primary financial incentive determining occupational choice

Payment linked to individual or firm performance

• Motivates workers and attracts those confident in their productivity

Non-salary financial benefits, including childcare support, private healthcare, pension contributions and company vehicles

• Can be significant in occupational choice, particularly in higher-income economies

Long training periods act as a barrier to entry, reducing the number of workers who supply labour to that occupation

It typically takes seven years to qualify as a doctor, restricting labour supply to medicine globally

Occupations with stable, long-term contracts attract more workers than those with short notice periods or high redundancy risk

Public sector employment in many economies offers greater security than private sector alternatives

Finding fulfilment in a role is a significant motivator — workers will accept lower wages for work they find meaningful

Teaching and nursing attract workers despite below-market wages in many countries

Occupations with clear promotion pathways and rising salaries attract more applicants

Management consultancy and investment banking attract graduates partly through defined career progression

Some occupations carry higher social recognition, increasing labour supply despite other disadvantages

Medicine and law attract workers partly through social status in many cultures

Safe, comfortable or flexible working environments increase labour supply to an occupation

Technology firms in South Korea, India and the USA attract workers through flexible hours and campus facilities

Workers increasingly value time outside work — occupations offering flexibility attract more applicants

The rise of remote and hybrid working post-2020 increased labour supply to roles offering location flexibility
