Is a Minimum Wage Law the Most Appropriate Policy for Inclusive Growth in Singapore?
Answer
Inclusive growth is growth that is sustained, broad-based across sectors, and creates productive employment for the majority — combining actual and potential economic growth with equity in income distribution. The thesis is that a minimum wage law is appropriate for the equity dimension but not, on its own, the most appropriate policy for inclusive growth as a whole, because it does little for sustained growth and carries real employment risks; the best answer is a policy mix in which the minimum wage plays a supporting, redistributive role.
Thesis — a minimum wage advances inclusive growth. A minimum wage raises the pay of the lowest earners (with spillover effects on jobs just above the floor), narrowing the wage gap and improving equity.
Because low earners have a high marginal propensity to consume, higher wages raise domestic consumption, lifting aggregate demand and actual growth. And by raising the marginal benefit of automation, a minimum wage can spur capital accumulation, while more attractive wages draw stay-home parents and seniors into the workforce — raising the quantity and quality of factors and so potential output.
Anti-thesis — the minimum wage may not be most appropriate. In a competitive labour market the wage floor creates a surplus — unemployment of . Worse, if firms automate, retrenched low-skilled workers face structural unemployment, lacking the skills to move to sunrise industries; since the low-skilled are the lower-income segment, inequity could worsen. The resulting unemployment also offsets the consumption boost, overstating the growth effect. On the cost side, higher factor costs raise unit costs of production, lowering short-run aggregate supply (cost-push inflation and lower output) and reducing firms’ expected returns and hence investment — damaging both actual and potential growth in an economy as FDI-dependent as Singapore’s.
Alternative policies. Transfer payments funded by progressive taxation target the lower-income directly, improving equity and (through their high MPC) raising consumption and actual growth — without the unemployment side effect. Supply-side skills-upgrading (SkillsFuture) raises low earners’ productivity and wages while lifting potential output, the most holistic route to inclusive growth. Each has limits: transfers strain the budget and are not sustainable long-term, and skills upgrading depends on workers’ receptiveness and the relevance of training.
Judgement. Whether a minimum wage is most appropriate depends on which facet of inclusive growth is prioritised. If equity comes first, a minimum wage is arguably most appropriate: it directly raises the lowest incomes, and in Singapore the damage to competitiveness is likely contained, because the export sectors driving growth are capital- or knowledge-intensive and employ skilled labour, while minimum-wage workers are concentrated in low-skilled domestic services. If sustained growth is the priority, supply-side skills policy dominates, since it raises productivity and growth with minimal trade-offs, and a minimum wage contributes little to long-run growth. Transfer payments work best as a short-term cushion but are fiscally unsustainable. The defensible conclusion is therefore that no single policy is “most appropriate” for all dimensions of inclusive growth: a minimum wage is the most appropriate equity lever and a reasonable means of sharing the fruits of growth, but it must be embedded in a mix led by supply-side skills upgrading (to secure sustained growth) and supported by targeted transfers — with the minimum wage calibrated to limit the unemployment and competitiveness costs the anti-thesis identifies.
