How Globalisation Changes Singapore's Comparative Advantage, and Whether Gaining It Always Benefits a Small Open Economy

Answer

Part (a)

Globalisation is the increasing integration of national economies through cross-border flows of trade, capital, labour, technology and ideas. A country has a comparative advantage in a good when it can produce it at a lower opportunity cost — in terms of other goods forgone — than another country. Globalisation changes Singapore’s comparative advantage over time by altering the resources and technology available to it, shifting the relative opportunity costs of its industries.

To see the principle, suppose Singapore can produce either electronics or textiles, and that an hour of resources yields more output, relative to textiles, when devoted to electronics than it does for a lower-cost competitor — so Singapore’s opportunity cost of a unit of electronics, measured in textiles forgone, is lower. By the theory of comparative advantage, Singapore should specialise in electronics and trade for textiles. (The illustration is kept to opportunity-cost reasoning; the syllabus does not require a numerical comparative-advantage table here.)

Globalisation shifts these opportunity costs. Freer movement of capital and technology brings foreign direct investment — firms such as global technology and pharmaceutical multinationals — which transfers the latest technology and raises productivity in high-value, capital- and skills-intensive sectors. This lowers Singapore’s opportunity cost of producing in those sectors, so it gains comparative advantage there. At the same time, freer movement of labour and capital lets emerging economies such as Vietnam and Thailand, with abundant cheap labour, undercut Singapore in labour-intensive production; their opportunity cost in those goods is now lower, so Singapore loses comparative advantage in its older labour-intensive industries — the sources of comparative advantage shift with factor endowments and technology. Over time, then, globalisation moves Singapore’s comparative advantage up the value chain — towards high-tech, knowledge-intensive output and away from low-end manufacturing.

Part (b)

A gain in comparative advantage allows a country to specialise and trade more profitably, which can raise its national income. The claim under test is whether this always yields a positive macroeconomic impact for a small and open economy. My thesis is that it usually does — but not always and not for every such economy, because the outcome is conditional on the country’s policies and the adaptability of its workforce.

The case that a CA gain benefits a small open economy. For a small and open economy, gaining comparative advantage — say in high-value manufacturing — raises export competitiveness and attracts FDI. Higher exports and investment raise aggregate demand, while the inflow of technology and capital raises productive capacity, raising aggregate supply. Both curves shift rightward, delivering non-inflationary growth, higher employment and an improved balance of trade simultaneously — a near-ideal macroeconomic outcome, and one especially valuable to an economy with a small domestic market that must rely on external demand.

The case that it does not always benefit. A gain in comparative advantage in one set of industries typically means a loss in others — the labour-intensive sunset industries that emerging competitors now make more cheaply. Workers displaced from those industries may be occupationally immobile, lacking the skills the rising high-tech sectors demand, so the economy can suffer structural unemployment. Because the gains accrue to capital and high-skilled labour while the losses fall on low-skilled workers, the shift can also widen income inequality — exactly the “skill-biased” pressure the stimulus identifies.

Evaluation — the impact is conditional. Whether the net macroeconomic impact is positive depends on the nature of the economy. Singapore exemplifies the favourable case: with proactive supply-side policy — reskilling, SkillsFuture, lifelong learning — and a workforce able and willing to retrain, it has converted CA gains into one of the world’s highest levels of real GDP per capita (PPP-adjusted), producing and consuming far beyond what its limited natural endowment alone would allow. But the same gain in a small open economy without such policy support, or with a workforce that cannot adapt, would leave a large pool of structurally unemployed and a worsening income distribution — so the impact would be far less clearly positive.

Judgement. A gain in comparative advantage is usually a powerful positive for a small and open economy, because specialisation and trade let it overcome the constraints of size and endowment to achieve non-inflationary growth, employment and external balance together. But it is not always positive, because the same gain entails losses in declining industries and a redistribution of income that, if unmanaged, produces structural unemployment and rising inequality. The decisive factor is policy and workforce readiness: where the government invests in reskilling and redistribution and workers adapt — as in Singapore — the gain is strongly beneficial; where it does not, the benefits are concentrated among a few while the costs fall on the displaced. The claim that a CA gain always benefits a small open economy is therefore too strong: it benefits one that is prepared to manage the transition, and only such a one to a large extent.
