Introduction
Stagflation, where an economy simultaneously experiences stagnant or negative growth alongside rising inflation, presents one of the most challenging policy dilemmas. Unlike typical demand-side problems, it stems from both weak aggregate demand and adverse supply-side shocks such as rising input costs or supply chain disruption. This creates conflicting economic objectives, as policies that boost growth often worsen inflation, and vice versa. While managing these conflicts is undoubtedly a key consideration, it is not the only factor. The root causes of stagflation and the structure of the economy also significantly influence policy choices.
Managing conflicting economic objectives
At the core of the stagflation dilemma is the incompatibility of standard goals, low inflation and high growth. Governments might use expansionary demand management to combat stagnation. The central bank may pursue expansionary monetary policy by increasing the money supply, which reduces interest rates. Lower interest rates make borrowing cheaper and reduce the opportunity cost of spending, encouraging consumption of durable goods and business investment, especially where investment is interest-elastic. This raises aggregate demand (AD), shifting the AD curve rightward, lifting real national income and reducing cyclical unemployment. However, if the economy is already at or near full employment, the increase in AD mainly raises the general price level, fuelling demand-pull inflation. So while the policy addresses the stagnation component, it worsens the inflation problem, creating a policy trade-off. The conflict between stabilising prices and promoting growth is therefore central, and managing this trade-off becomes a primary concern.
Understanding the nature of the cause of stagnation
While conflicting goals are important, the underlying cause plays a critical role in determining the appropriate response. If stagflation is driven primarily by supply-side constraints, such as a shortage of skilled labour, rising energy prices or disrupted logistics, then using demand-side tools alone may be ineffective or counterproductive. In such cases supply-side policies are more suitable. The government could implement tax incentives or subsidies to encourage labour force participation among older workers or caregivers, while grants for firms to adopt automation could raise productivity, easing supply constraints and shifting the Short-Run and Long-Run Aggregate Supply curves rightward. These address cost-push inflation arising from supply bottlenecks while contributing to potential growth, reducing inflation risk in the long term without worsening unemployment. Understanding whether stagflation stems from cost-push factors or structural weaknesses is essential, since a misdiagnosis, such as expanding demand in an inflationary context, could make things worse.
The structure of the economy
The structure of the economy also matters when selecting policy tools. In export-oriented economies such as Singapore, boosting domestic demand may not be enough to reignite growth, so governments might look toward exchange rate policy to manage the trade balance and stimulate external demand. A depreciation of the exchange rate makes exports cheaper and imports more expensive, boosting net exports and AD, but it can also worsen imported inflation if the country depends heavily on imported essentials. Conversely, an appreciation reduces imported inflation by lowering the cost of foreign goods, but makes exports more expensive, reducing competitiveness and potentially leading to slower growth and higher unemployment in export-reliant industries. This creates another trade-off between external competitiveness and price stability, and governments must evaluate the import-intensity of consumption and production before deciding which way to lean.
Evaluative conclusion
Managing conflicting macroeconomic objectives, balancing growth and inflation, is undoubtedly a key consideration for governments facing stagflation, since the tools for addressing one problem often worsen the other. However, it is not the only factor. The underlying cause, such as supply-side constraints versus demand weakness, and the economic structure, particularly trade dependence and import reliance, are also crucial. Governments that understand the specific context of stagflation within their economy, rather than applying generic responses, are better equipped to implement policies that restore both stability and growth over the medium to long term.
