Factors Behind Singapore's Actual and Potential Growth, and the Impact of Tightening Foreign Labour on Living Standards

Answer

Part (a) — Factors contributing to actual and potential growth [10]

Actual growth is a rise in real national income — the actual use of an economy’s capacity — and can come from an increase in aggregate demand or aggregate supply. Potential growth is a rise in productive capacity, shown by an outward shift of long-run aggregate supply driven by more or better factors of production.

Internal demand-side factor. Improved consumer sentiment — better job prospects and sound policy — raises consumers’ willingness to spend, lifting C and hence AD = C + I + G + (X − M). The rightward shift of AD sets off the multiplier: firms draw down inventories, raise output, hire more factors and pay out more income, inducing further consumption round by round until injections again equal withdrawals. With spare capacity (intermediate range), AD rises produce a multiplied rise in real GDP — actual growth.

Internal supply-side factor. Government supply-side policy raises the quality and quantity of factors. Schemes such as SkillsFuture and the Adapt-and-Grow initiative raise labour quality; R&D funding (e.g. the $19 billion RIE2020 plan) and tax incentives to attract FDI raise capital quantity and quality. These shift LRAS outward (LRAS₀→LRAS₁), raising full-employment output Yf₀→Yf₁ — potential growth — and, if the economy is near full employment, actual growth too.

External factor. Growth in major export markets (China, the Eurozone) raises their purchasing power and demand for Singapore’s exports — semiconductors, finance, transport — lifting (X − M). For a very open economy with a trade-to-GDP ratio above 300%, this is a large effect. Inbound FDI (e.g. US$58 billion in 2017) raises I. Both feed AD and, via the multiplier, actual growth.

Part (b) — Impact of tightening foreign labour on living standards [15]

Tightening foreign labour — higher levies, minimum salary thresholds, fewer low-skilled work permits — aims to push firms toward innovation and automation. Living standards cover both the material dimension (goods and services available for consumption) and the non-material dimension (leisure, life expectancy, education, environment). Singapore is a small, open economy heavily reliant on foreign manpower given its small and ageing population.

Argument: living standards rise. Restricting foreign labour raises wage costs, incentivising firms — especially SMEs — to substitute capital for labour and adopt more productive, capital-intensive methods. Government co-funding (e.g. $2.5 billion for Continuing Education and Training over 2010–2015) supports this. Higher productivity lowers unit costs, raising SRAS and dampening inflation; cheaper, more price-competitive exports raise (X − M) and AD where export demand is price-elastic. Rising real national income lifts purchasing power and material living standards. Over time, automation raises productive capacity, delivering potential growth and a sustainable inflation rate. Stricter immigration also relieves congestion of public transport and amenities, raising non-material living standards by easing local discontent.

Counter-argument: living standards fall. Restructuring toward automation reduces demand for lower-skilled labour and raises it for higher-skilled labour. Less-educated workers, slow to retrain, face structural (technological) unemployment — a fall in material living standards. The skill-biased shift also widens income inequality: wages rise for high-skilled and stagnate for low-skilled workers, fuelling social tension and lowering non-material living standards. In the short run, wages rise faster than productivity — efficiency gains take time — so unit labour costs rise. Where automation is infeasible (construction, services), firms must pay higher wages to scarce foreign or local workers, raising costs, contracting SRAS and pushing the price level up. Higher cost of living erodes purchasing power and material living standards.

Judgement. The sign of the effect turns on the time horizon and on which industries are affected. Productivity gains can offset higher domestic costs, but mindsets and processes change slowly, so the benefits accrue in the long run while the costs — short-run cost-push pressure and transitional structural unemployment — bite immediately. The policy is better targeted than blanket: loosening for genuinely low-skilled roles locals avoid, while raising the retirement age (62 to 65 by 2030) to expand the resident workforce, mitigates the short-run cost shock. Lifelong-learning measures (SkillsFuture) raise the eventual success of retraining and erode the structural-unemployment objection over time. On balance, tightening foreign labour is likely to raise living standards in the long run but lower them in the short run — so its net welfare effect depends on how well the transition is cushioned.
