Which of the following is the resultant effect of a fall in the profit margin of producers in an economy?

Analyze the question: The question asks what happens to employment when producers' profit margins fall.

Concept: Profit is the main motive for production. Firms hire labour and produce goods only when they expect to earn a satisfactory return. When the profit margin falls, firms usually respond by cutting costs and scaling down output. Labour is one of the biggest costs, so it is often the first to be reduced.

Step-by-step solution:

1. Profit margin falls, so the return on production is lower.
2. Producers have less incentive and less ability to invest and expand. Some firms cut output, and some shut down.
3. Lower output means less demand for labour, so firms lay off workers or stop hiring.
4. Fewer jobs means unemployment increases.

Checking the options:

• A. Unemployment will fall: wrong, because less profit does not encourage firms to hire more.
• B. Unemployment will remain constant: wrong, because firms adjust their labour force when profitability changes.
• C. Unemployment will increase: correct, for the reasons above.
• D. Unemployment will fluctuate: wrong, because this is vague and does not describe the direct effect. The effect is a rise.

Exam tip: Link profit to production and production to employment: profit down → output down → jobs down → unemployment up. For JAMB questions on changes in profit, look for the effect on firms' output and hiring.
