The basic economic problem arises because resources are scarce while human wants are unlimited. In the labour market this means that the supply of workers (and their skills) is limited compared with the demand for work.
When the quantity of labour supplied exceeds the quantity demanded at the prevailing wage, some workers remain unemployed.
Employers may need workers with specific skills, but the available workforce may lack those qualifications. This creates a shortage of skilled labour and a surplus of unskilled labour.
Because labour is scarce, wages must be set at a level that balances the limited supply of workers with the demand from firms. The equilibrium wage \$w^*\$ satisfies:
\$ QD^L(w) = QS^L(w) \$
where \$QD^L\$ is the quantity of labour demanded and \$QS^L\$ is the quantity of labour supplied.
When a person chooses to work, the opportunity cost is the value of the next best alternative foregone, such as leisure or further education. This can be expressed as:
\$ \text{Opportunity Cost} = \text{Value of Leisure or Study} - \text{Wage Earned} \$
Resources (workers) must be allocated between agriculture, manufacturing and services. Because the total labour pool is limited, a decision to increase workers in one sector reduces the number available for others.
| Choice | Alternative 1 | Alternative 2 | Opportunity Cost |
|---|---|---|---|
| Employment vs. Education | Take a job now (earn wage \$w\$) | Study full‑time (future higher wage \$w'\$) | \$w\$ (current earnings) vs. \$w' - w\$ (future gain) |
| Full‑time vs. Part‑time work | Full‑time (higher income, less leisure) | Part‑time (lower income, more leisure) | Lost income vs. lost leisure time |
| Urban job vs. Rural job | Urban (higher wage, higher living costs) | Rural (lower wage, lower living costs) | Difference in net disposable income |
The basic economic problem for workers is the need to allocate scarce labour resources among competing uses. This leads to unemployment, wage determination, skill mismatches and trade‑offs between work, education and leisure. Understanding these examples helps students grasp how scarcity shapes economic decisions at both the individual and societal level.
