Macroeconomic objectives

Key goals of governments in achieving economic stability include sustainable growth, low inflation, low unemployment, balanced trade, and income equality.

Governments aim to achieve multiple macroeconomic objectives simultaneously, including price stability, full employment, economic growth, and balance of payments stability.
But pursuing one objective often requires trade-offs with others, creating complex policy dilemmas, because using demand-side policy to hit one target usually moves another the wrong way.

Low Unemployment and Low Inflation

Defining Low Unemployment

The lowest sustainable unemployment rate an economy can achieve without triggering accelerating inflation is called the natural rate of unemployment (typically 4 to 6%).
Frictional, structural, and cyclical unemployment all contribute to the natural rate. When these types remain low, the natural rate is also low.

Common Mistake

Students often think 0% unemployment is ideal and achievable. However, some unemployment is natural and even necessary for a healthy economy!

Defining low inflation

Low inflation is typically defined by central banks as a stable price level with inflation around 2%.

Example

The European Central Bank (ECB) aims for inflation “below, but close to 2%.”
When inflation surged to 10.6% in 2022, the ECB took dramatic action by raising interest rates.

Common Mistake

Many students think zero inflation is best.
Actually, a small positive inflation rate helps the economy adjust to shocks and prevents deflation!

In an ideal world, we would want both low inflation and low unemployment.
1. Low unemployment drives economic growth and higher GDP, while also reducing government spending on welfare.
2. Low inflation ensures price stability and economic certainty, which are vital for planning.
3. Low inflation also boosts international competitiveness, as exports become cheaper, leading to greater demand.
But these objectives are not fully independent. They are interconnected through wage pressures and aggregate demand, meaning there is often a trade-off: low unemployment versus low inflation, because pushing unemployment below the natural rate tightens the labour market and raises aggregate demand, which pulls the price level up and lifts inflation.

Example

During the 1960s, Australia maintained unemployment below 2% while experiencing strong economic growth.
This “golden age” demonstrated how low unemployment can boost an economy’s overall performance.

Theory of Knowledge

How do we determine the “optimal” balance between unemployment and inflation?
This raises questions about measuring social welfare and making economic trade-offs.

Interactive question

A government wants to drive unemployment below the natural rate by boosting aggregate demand. Which outcome does economic theory predict?

Inflation stays constant, because unemployment and inflation are unrelated.

Both unemployment and inflation fall together with no trade-off.

Inflation tends to rise, because a tighter labour market pushes up wages and stronger demand pushes up the price level.

Unemployment can be held below the natural rate permanently at no cost.

Markscheme

Pushing unemployment below the natural rate tightens the labour market, raising wage demands and aggregate demand, which lifts the price level, so inflation rises. This is the low unemployment versus low inflation trade-off. [1]

Trade-off between unemployment and inflation (HL only)

The relationship between unemployment and inflation was first identified by A.W. Phillips in the 1950s, based on observations of wage rates and unemployment data.
