b. Explain why using a mix of economic policies is essential for the Singapore government to meet its various macroeconomic objectives concurrently. [15]
introduction
Governments aim to achieve key macroeconomic objectives such as low unemployment, low inflation, and sustainable economic growth, but in practice, pursuing one objective often comes at the cost of another. This creates policy trade-offs, making it necessary to implement a mix of policies rather than relying on a single approach. In Singapore’s case, the small and open nature of the economy further restricts the choice of policy instruments, particularly in monetary policy, where exchange rate management is prioritized over interest rate control. As a result, the government must adopt a combination of demand-side, supply-side, and exchange rate policies to balance economic growth, price stability, and employment while ensuring long-term sustainability.
Policy Trade-offs Require a Mix of Policies
Achieving sustainable economic growth without negative side effects is an ideal objective, but in reality, the pursuit of growth often leads to inflation, income inequality, or environmental degradation. This makes it difficult for a single policy to address all macroeconomic goals simultaneously.
Trade-off between growth and inflation: Singapore operates near full employment, meaning that any increase in aggregate demand (AD) beyond aggregate supply (AS) capacity is likely to result in demand-pull inflation rather than real economic expansion.
Trade-off between growth and income equality: Economic growth in a globalised economy often benefits higher-skilled workers more than lower-skilled workers, leading to greater income disparity. Without redistributive policies such as progressive taxation or workforce upskilling, income inequality may worsen.
Trade-off between growth and environmental sustainability: Rapid economic growth can lead to environmental degradation due to increased industrial activity and energy consumption. Implementing environmental regulations, such as carbon taxes or green technology incentives, can increase business costs and reduce investments, potentially leading to higher unemployment in affected industries.
Since no single policy can effectively balance these trade-offs, Singapore must implement a mix of demand-side, supply-side, and environmental policies to manage growth, inflation, and inequality simultaneously.
Singapore’s Economic Structure Limits Policy Choices
Singapore’s small and open economy means that monetary policy options are constrained, requiring the government to adopt a mix of policies to achieve its macroeconomic goals.
The Monetary Policy Trilemma:
Singapore faces the monetary policy trilemma, where an economy can only choose two of the following three:
Control of interest rates
Control of exchange rates
Free capital flows
As an export-dependent economy with free capital mobility, Singapore prioritises exchange rate management over interest rate control. This means that interest rates are not an available policy instrument, and exchange rate policy becomes the primary tool for monetary stability.
Exchange Rate Policy as the Primary Monetary Tool
Given Singapore’s reliance on trade and imports, the Monetary Authority of Singapore (MAS) manages the exchange rate to maintain price stability and economic competitiveness.
The typical stance of Singapore’s monetary policy is a modest and gradual appreciation of the Singapore dollar (SGD).
This helps control inflation by reducing imported inflation, cost-push inflation, and demand-pull inflation, keeping overall price levels stable.
However, a stronger SGD can make exports more expensive, reducing their competitiveness in global markets and potentially leading to slower economic growth.
Since exchange rate appreciation alone cannot fully address inflation or sustain export competitiveness, Singapore must complement it with supply-side policies.
The Need for Supply-Side Policies
To counteract the potential downsides of exchange rate appreciation, supply-side policies are essential for maintaining Singapore’s economic growth and competitiveness.
Instead of relying on currency depreciation to make exports cheaper, Singapore focuses on enhancing workforce skills and productivity. Policies such as skills upgrading programs and automation incentives allow firms to produce higher-value goods and remain competitive despite a stronger currency.
Since exchange rate appreciation may not fully contain inflation, Singapore adopts strategies such as expanding trade agreements and diversifying import suppliers to ensure price stability for essential goods.
Investments in R&D, digital transformation, and smart manufacturing reduce long-term reliance on labour-intensive industries and help Singapore stay competitive in high-value industries.
By implementing these long-term structural reforms, the government ensures that economic growth is both sustainable and inclusive, reducing income inequality and inflationary pressures while maintaining a strong export sector.
Conclusion
Given the conflicting nature of macroeconomic objectives and the structural constraints of Singapore’s economy, a mix of policies is necessary to achieve sustainable economic growth, low inflation, and low unemployment. Exchange rate policy helps stabilise inflation but needs to be balanced with supply-side policies to maintain export competitiveness. At the same time, supply-side measures such as productivity growth and workforce upskilling are essential to address income inequality and structural unemployment. Since no single policy can effectively resolve all economic challenges, the Singapore government must continue using a carefully coordinated mix of monetary, supply-side, and fiscal policies to achieve long-term economic stability and inclusive growth.
