Introduction
A minimum wage law and a tightening of the foreign worker quota policy are two strategies aimed at reducing income inequality in Singapore. Both policies target the wages of low-skilled workers, but they operate through different mechanisms. This essay assesses each policy in turn and judges which is more appropriate for Singapore.
Minimum wage law
A minimum wage is a legally mandated price floor on wages, set above the equilibrium wage level for low-skilled workers. Its intent is to raise the incomes of low-skilled, low-wage workers to what is considered a living wage. By increasing their wages, a minimum wage aims to reduce income inequality, narrowing the income gap between low-skilled and high-skilled workers.
By setting the wage floor above the market equilibrium wage Pe, the quantity of workers demanded by firms falls from Qe to Qd, as firms face higher labour costs and have less incentive to hire. At the same time the quantity of workers supplied rises from Qe to Qs, because higher wages attract more individuals into the labour market. The result is a surplus of workers, the gap between Qd and Qs, which amounts to unemployment. This unemployment is especially pertinent in industries where firms reduce their workforce in response to higher labour costs, ultimately undermining the policy's goal of reducing income inequality.
Furthermore, a minimum wage raises the cost of production for firms, especially in labour-intensive industries, shifting the short-run aggregate supply curve leftward from AS₀ to AS₁ and raising the price level from P₀ to P₁. Firms may pass these higher costs on to consumers as higher prices, producing cost-push inflation. Higher wages for workers in the retail or food and beverage (F&B) sectors, for example, could raise prices for goods and services. This inflationary effect could disproportionately harm low-income households, whose real incomes may not keep pace with price increases, negating the benefits of the minimum wage.
Firms may also respond to higher wage costs by investing in automation to replace low-skilled labour. Companies such as McDonald's have adopted self-checkout kiosks to reduce reliance on low-wage workers, and firms like Amazon have increasingly automated warehouse operations. This shift towards automation could worsen structural unemployment, as low-skilled workers find it harder to secure jobs in a more technologically advanced labour market.
In the Singapore context the appropriateness of a minimum wage is questionable. While it may raise wages for low-income workers in the short term, the risks of unemployment, inflation and structural change make it less attractive. Singapore is also a highly export-oriented economy, so higher wage costs could hurt its export competitiveness. As firms face rising costs they may pass them on to consumers or cut back production, both of which could damage the broader economy.
Tightening the foreign worker quota policy
An alternative policy is to tighten the foreign worker quota. In Singapore the Dependency Ratio Ceiling (DRC) limits the proportion of foreign workers a company can hire relative to local workers. Tightening this policy would mean reducing the DRC, forcing firms to hire more local workers if they wish to employ foreign labour. By raising the demand for local low-skilled workers, this policy can lift their wages and so reduce income inequality.
Reducing the supply of foreign low-skilled workers, or restricting its growth, increases the bargaining power of local workers and drives up their wages. In theory this reduces income inequality as low-income local workers benefit from higher wages in sectors such as construction, retail and F&B. However, tightening the quota could also raise production costs for firms, since foreign workers generally accept lower wages than local counterparts, and firms may pass these costs on to consumers, leading to inflation similar to the minimum wage effect.
One advantage of tightening the foreign worker quota over a minimum wage is that it targets the root of the wage disparity, an oversupply of low-cost foreign labour. By limiting the number of foreign workers, the policy raises demand for local workers and their wages without directly imposing a wage floor that could create labour-market distortions. The impact may also be more gradual, giving firms time to adjust, unlike a sudden wage increase imposed by a minimum wage.
The policy is not without drawbacks. As with the minimum wage, firms facing higher labour costs from a reduced supply of foreign workers may turn to automation, which could again cause structural unemployment in industries where tasks are routine and easily automated. In sectors where foreign workers are vital, such as construction, tightening the quota could cause labour shortages, slowing projects and raising costs across the board.
Evaluative conclusion
In the case of Singapore, both a minimum wage and a tighter foreign worker quota can address income inequality by raising the wages of low-skilled workers. However, the risks attached to a minimum wage, namely unemployment, inflation and accelerated automation, make it the less appropriate tool. Tightening the foreign worker quota, while not without its own challenges, is a more targeted approach that avoids the rigidities of a wage floor and can gradually improve the wage prospects of local low-skilled workers. On balance, given the country's reliance on foreign labour and the threat that a minimum wage poses to inflation and export competitiveness, tightening the foreign worker quota is the more appropriate policy for reducing income inequality in Singapore.
