The Links Between Growth, Unemployment and Inflation, and Whether Restructuring Plans Raise Living Standards

Answer

Part (a)

Economic growth is the increase in a country’s real national output; unemployment is the proportion of the labour force willing and able to work but without a job; inflation is a sustained rise in the general price level. These three objectives are interlinked through the AD–AS framework. This essay traces two links: growth with falling unemployment, and continued growth with rising inflation.

Higher growth is associated with lower unemployment. Assuming the economy is operating below full capacity, growth is typically driven by rising aggregate demand — for instance, higher consumer and investor confidence raising consumption (C) and investment (I). As AD rises from AD₀ to AD₁, firms respond by raising output, and real national output rises from Y₀ to Y₁. To produce more, firms employ more factors of production, including labour, so demand-deficient unemployment falls. Higher growth therefore tends to come with lower unemployment.

Higher AD raises output and reduces unemployment, then strains capacity and lifts prices. As AD rises from AD₀ to AD₁ to AD₂ along the intermediate-to-classical AS, output rises from Y₀ towards full employment and the general price level rises from P₀ to P₂ — growth, lower unemployment, and then inflation.

Growth with lower unemployment can then generate inflation. As AD continues to rise (AD₁ to AD₂) without a matching rise in aggregate supply, spare capacity is used up and resources become scarce. Firms compete for an increasingly limited pool of factors — labour especially, as unemployment falls — bidding up wages and other input costs. Rising costs are passed on as higher prices, so the general price level rises from P₃ to P₄: demand-pull inflation, reinforced by the cost pressure from tight factor markets. Thus the same demand-led expansion that lowers unemployment eventually raises inflation.

Consolidation. The three objectives are inter-related through AD and AS: demand-led growth lowers unemployment as output expands, but as the economy nears full capacity the same growth drives up the price level. This is why governments find the objectives difficult to achieve simultaneously, and must use policy to manage the trade-offs.

Living standards have a material dimension — real GDP per capita and purchasing power — and a non-material dimension — pollution, income distribution, life expectancy and the like. The plans combine grants for energy-efficient and digital investment with a higher carbon tax. My thesis is that, in the long run and with supporting policy, the plans raise living standards for Singapore as a whole, but in the short run and for specific groups they can lower both material and non-material living standards, so the net effect depends on the time frame and on complementary government action.

The plans can raise living standards through faster, lower-inflation growth. Grants absorb part of firms’ investment costs, raising the expected return on investment and lifting investment spending (I), so AD rises — actual growth. Investment in technology also raises the quantity and quality of resources, shifting long-run aggregate supply right — potential growth. With both AD and LRAS rising, real national output rises from Y₀ to Y₁ while the average cost per unit falls as firms become more productive, so the price level rises only modestly. Higher output means more jobs and lower demand-deficient unemployment; combined with contained inflation, this raises purchasing power and hence material living standards. With higher incomes, households access better education and healthcare, raising literacy and life expectancy — non-material living standards. Lower emissions, encouraged by the energy-efficiency grants and the carbon tax, further improve the non-material dimension.

Restructuring raises both demand and capacity: grants lift investment so AD rises (AD₀→AD₁) while technology raises LRAS (LRAS₀→LRAS₁); output rises from Y₀ to Y₁ with only a modest rise in the price level — non-inflationary growth.

Against this, the plans can lower living standards for some, especially in the short run. As the economy digitalises, firms substitute technology for low-skilled labour — cashiers, manual roles — so demand for low-skilled workers falls and structural unemployment rises among those whose skills no longer match available jobs. These workers see wages fall and, if the fall outpaces any fall in prices, lose purchasing power — lower material living standards. Meanwhile demand for high-skilled workers rises, widening income inequality and worsening the non-material dimension. The higher carbon tax raises costs for emitters, who pass on higher prices for essentials such as electricity and transport; lower-income households, who spend a larger share of income on these, are hit hardest, compounding the squeeze on their living standards.

Judgement. Whether the plans raise living standards overall depends chiefly on time frame and on complementary policy. In the short-run transition, sectors reliant on manual labour see falling living standards for displaced workers and a rising cost of living for the poor. But these costs are largely transitional, and the government can offset them — cash vouchers to cushion higher prices (funded partly from carbon-tax revenue), and retraining and upskilling to move displaced workers into the new, higher-productivity jobs. In the long run, once restructuring succeeds and is paired with such measures, both the material and non-material dimensions improve broadly, and the lower-emission economy is more sustainable. On balance, then, the plans raise living standards for Singapore over the long run, but their net effect in the short run, and for the low-skilled in particular, turns on how effectively the government redistributes the gains and supports the transition.
