Discuss whether supply-side policy is the most appropriate policy to be used in addressing stagflation.
Life in Singapore has largely returned to the way it was before COVID-19. However, there remains a risk of stagflation—a rare economic condition where sluggish growth occurs alongside rising inflation.
b. Discuss whether supply-side policy is the most appropriate policy to be used in addressing stagflation. [15]
Introduction
Stagflation is an economic condition characterized by slow economic growth and persistently high inflation occurring simultaneously, presenting a unique challenge for policymakers as traditional demand-management policies often fail to address both issues effectively. In the case of Singapore, stagflation may arise due to weak economic growth in major trading partners such as the United States and China, as well as imported inflation caused by higher global oil and food prices, exacerbated by events such as the Russia-Ukraine war. Given that stagflation is caused by both supply-side constraints and demand-side weaknesses, supply-side policies—which focus on enhancing productivity, improving export competitiveness, and reducing inflationary pressures—can play a role in mitigating its effects. However, while these policies address long-term economic resilience, they may not provide an immediate solution to stagflation, making it necessary to consider complementary policies such as fiscal expansion or exchange rate adjustments.
How Supply-Side Policies Can Address Stagflation
1. Increasing Economic Growth by Boosting Export Competitiveness
A key component of Singapore’s economic performance is its export sector, which contributes significantly to aggregate demand (AD). Supply-side policies can be implemented to enhance export competitiveness, thereby stimulating growth.
The government can provide tax incentives or subsidies to encourage firms to adopt technology, automation, and skills upgrading programs.
Higher productivity lowers the cost of production, making Singapore’s exports more price-competitive.
A fall in export prices (Pₓ) increases the demand for Singapore’s goods and services internationally, leading to an increase in net exports (X-M).
As (X-M) rises, AD increases, leading to higher real national income and economic growth.
Evaluation:
While supply-side policies can boost export competitiveness, their impact takes time to materialize since productivity improvements and technological adoption require long-term investment and workforce adaptation.
These policies are also costly to implement, requiring significant government spending on subsidies, training programs, and technological advancements, which may be challenging if fiscal constraints exist.
2. Reducing Inflation by Diversifying Import Sources and Increasing Domestic Production
A major contributor to Singapore’s inflation during stagflation is imported inflation, particularly due to rising global food and energy prices. Supply-side policies can help mitigate these price pressures by diversifying import sources and increasing domestic production of essential goods.
By expanding trade agreements and sourcing from multiple countries, Singapore can reduce its dependence on a few key suppliers.
For example, the government introduced the 30-by-30 initiative, which aims to increase local food production to cover 30% of Singapore’s nutritional needs by 2030.
This initiative helps mitigate supply disruptions, such as Malaysia’s export bans on chicken and eggs, which had previously contributed to rising food prices.
By subsidizing local production of essential goods, the government can stabilize domestic supply and reduce reliance on volatile international markets, thus lowering inflationary pressures.
Evaluation:
While increasing domestic production of essential goods can reduce imported inflation, it may violate the principle of comparative advantage, where countries should specialize in producing goods they are most efficient at and import others.
The cost of producing food or other essential goods domestically may be higher than importing them, potentially leading to higher opportunity costs and inefficiencies in resource allocation.
Nevertheless, in situations of supply chain disruptions or geopolitical risks, such policies may still be justified to enhance economic resilience despite their inefficiencies.
Alternative Policies to Complement Supply-Side Measures
Given that supply-side policies have long-term effects and require significant government spending, alternative policies may be necessary to stabilize the economy in the short run.
1. Expansionary Fiscal Policy to Stimulate Growth
The government could increase public spending (G) on infrastructure, healthcare, or other projects, boosting AD and stimulating real national income through the multiplier effect.
A reduction in corporate income tax (CIT) could increase after-tax profits, encouraging firms to expand investments (I) and hire more workers.
Similarly, a reduction in personal income tax (PIT) increases disposable income, enhancing household consumption (C), which raises AD and national income.
Evaluation:
If the economy is already near full employment, increasing AD could worsen inflation rather than boost real output, making stagflation more severe.
Fiscal expansion should therefore be targeted towards productive investments that enhance long-term supply-side capacity rather than merely increasing demand.
Conclusion
While supply-side policies are crucial in addressing stagflation by boosting economic growth and reducing inflationary pressures, their effectiveness is limited by time lags and high implementation costs. Productivity-enhancing policies can improve export competitiveness and expand potential output, but they take years to materialise. Similarly, diversifying import sources and increasing domestic production can stabilise inflation, but may violate comparative advantage principles and lead to inefficiencies. Given these limitations, supply-side measures alone are insufficient to fully address stagflation. Instead, a combination of policies is necessary, including short-term fiscal measures to stimulate growth and monetary or trade policies to manage inflationary risks. By adopting a balanced approach, Singapore can navigate stagflation while ensuring long-term economic stability and resilience.
