Factor Rewards
Definition
Factor rewards: the incomes earned by the factors of production; rent for land, wages for labour, interest for capital and profit for enterprise.
- Because each factor is scarce, firms must pay to use it, and every payment a firm makes becomes income for whoever owns that resource.
- These rewards therefore link the use of resources to the distribution of income across households: own more scarce factors, earn more.
Key Idea
- The four factor rewards are rent, wages, interest and profit.
- They connect production to how income is shared out.
The Four Rewards
- Land earns rent
- This is the payment for the use of natural resources, such as £2,000 a month for a shop unit.
- Labour earns wages
- This is the payment for human physical and mental effort, including salaries.
- Capital earns interest
- This is the return on the funds tied up in machinery and equipment.
- Enterprise earns profit
- This is the reward for organising the other factors and bearing the risk that output may not sell, so it is what is left after the other three are paid.
Note
- These rewards are the household incomes that flow round the circular flow of income.
- They also form the basis of how income is distributed across households.
Example
- A logistics firm pays rent of £5,000 a month on its warehouse, wages to its drivers, interest on the loan used to buy its trucks, and the owner keeps the profit.
- Each payment matches one factor to its own reward, so the terms must not be swapped.
- If a skill such as software engineering is scarce, demand for it is high relative to its supply in the labour market.
- This bids up the wage for that skill, so factor rewards widen income differences between workers.
Why They Matter
- They explain how income is distributed between the different owners of resources.
- Differences in rewards, such as high wages for scarce skills, reflect supply and demand in each factor market: scarce supply plus strong demand raises the price of that factor.
- How far rewards create inequality depends on how unequally the ownership of factors is spread in the first place, so it depends on context.
Exam technique
- State the four factors and their matching rewards using the exact terms rent, wages, interest and profit.
- Link factor rewards to the distribution of income when a question turns to inequality.
- Explain a reward difference using factor supply and demand, not just assertion.
Common Mistake
- Do not mix up the rewards: land earns rent, labour earns wages, capital earns interest and enterprise earns profit.
- Do not treat profit as the reward for capital, since profit rewards enterprise while interest rewards capital.
Self review
- Name the four factors of production and the reward each earns.
- What reward does enterprise earn, and why is it distinct from interest?
- How do factor rewards link to income distribution?
- Why might one type of labour earn higher wages than another?
