Part (a): Changes in Total Expenditure on Workforce (10 Marks)
[Point] Total expenditure on a workforce (TE) is calculated as the wage per worker (W) multiplied by the number of workers employed (L). Wages and employment levels are determined by the intersection of the demand and supply of labour.
[Explanation – Demand Shift] As given in the preamble, there is an increased demand for labour. This causes the demand curve for labour to shift to the right. As a result, a shortage arises at the original wage rate (W1), creating upward pressure on wages as firms bid up wages to obtain scarce labour. As wages increase, the quantity demanded for labour will fall along the curve, whilst the quantity supplied increases. This brings the market to a new, higher equilibrium (W2, L2). As both wages and the number of workers employed have increased, the TE clearly increases.

[Explanation – Supply Shift & Elasticity] Simultaneously, due to “large numbers of workers retiring,” the supply of labour falls, shifting the supply curve to the left (from SS1 to SS2). This creates a shortage and upward pressure on wages. The equilibrium wage increases to W2, whilst the equilibrium quantity of labour falls to L2, which normally makes the effect on TE ambiguous.
[Link] However, because the demand for this firm’s labour is wage-inelastic, the quantity demanded will fall less than proportionately to the rise in wages. Therefore, TE will increase. Referring to the diagram, Area A represents the increase in TE due to the higher wage paid, while Area B represents the fall in TE due to the fall in labor. Because Area A exceeds Area B, TE increases.

Part (b): Evaluating the Foreign Worker Levy (FWL) (15 Marks)
[Point] The Foreign Worker Levy (FWL) is a tax imposed on the employment of foreign low- and mid-skilled workers. Its aim is to make it more expensive for domestic firms to hire foreign labor, protecting domestic workers.
[Explanation] Reducing the FWL will reduce the cost of hiring foreign low-skilled workers, enabling domestic firms to hire them as relatively cheaper substitute labor. This reduces the firm’s demand for local workers, alleviating the immediate domestic labor shortage.

[Evaluation – Anti-Thesis (Limitations of FWL)] However, relying on FWL adjustments is severely limited. First, there are foreign worker quotas (Dependency Ratio Ceilings) in place. Even if it is cheaper to hire a foreign worker due to a reduced levy, once the quantity restriction is reached, the firm cannot hire more. Second, the FWL is irrelevant for high-skilled labor shortages. Because Singapore focuses on high-value-added sectors, booming industries desperately need skilled workers. With a shrinking domestic labor force and fierce global competition for talent, the shortage of high-skilled labor will persist regardless of the FWL.
[Point – Alternative Policies] Instead of relying on foreign workers, the government should address shortages by increasing labor productivity through capital substitution (automation). For example, using an automated building assembly line instead of manual construction workers means more output is produced with less labor.
[Explanation] The government can provide subsidies and grants to co-fund automation and worker retraining. This will allow for more output to be produced with same amount of labour, reducing the demand for labour and hence the shortage of labour.
[Evaluation – (Limitations of Alternative Policy)] However, some jobs (like garbage collection) cannot be easily automated. The preamble notes that the firm’s demand for labor is inelastic. This suggests that there are very few viable capital substitutes for human workers in this specific industry. It would also take considerable time to change the work processes and to also upskill the workers. Some workers may also face difficulties adapting or may resist the new production methods. Hence, this policy may not be able to reduce the shortage effectively especially in the short-term,.
[Concluding Section / Synthesis] In conclusion, reducing the FWL is not the most effective long-term way to address labour shortages due to quota limitations and its inability to solve high-skilled talent gaps. The most effective, sustainable policy is the aggressive encouragement of automation and productivity, subsidized by the government. By upgrading jobs to be less laborious, older workers can also remain in the workforce longer. Nevertheless, as there are also challenges in adopting automation, the most effective way to tackle the shortage would be a combination of both measures as a multi-pronged, short-term and long-term combination.
