2.1.3 - Conflicts between objectives and policies

Unemployment and inflation

A macroeconomic trade-off occurs when improving one objective makes another harder to achieve under the prevailing conditions.

Lower unemployment and low, stable inflation are both desirable. When unemployment results from weak spending, government purchases or tax cuts can increase businesses' orders. Lower interest rates can also make borrowing cheaper and saving less attractive, encouraging consumption and investment. Firms may increase output and employ more workers. If unused labour and capacity are available, this can reduce unemployment without much extra price pressure.

As capacity becomes scarce, firms find it harder to expand production. Competition for skilled workers can raise wages and costs, while extra spending allows sellers to raise prices. A policy reducing unemployment through stronger spending may then increase demand-pull inflation. Conversely, higher interest rates or tighter fiscal policy can restrain spending and inflation, but fewer orders may cause firms to reduce hiring or dismiss workers. Identify the causal chain rather than merely stating that the two figures move in opposite directions.

The conflict is conditional. A cost shock such as expensive imported fuel can raise inflation while reducing output and employment, so high unemployment and high inflation can occur together. Training that improves the fit between workers and jobs can reduce structural unemployment and expand capacity, easing price pressure. There is no fixed exchange rate between one percentage point of unemployment and one percentage point of inflation to memorise.

For an illustrative economy with idle factories and falling sales, a modest temporary spending increase may mainly help employment. For an economy with shortages of skilled labour and rapidly rising sales, the same policy risks inflation. Tightening policy after an energy shock might reduce wider inflation pressure, but it cannot directly supply the missing energy and may deepen unemployment. A policy judgment therefore requires evidence about the cause of both problems and how strongly spending responds.

Economic growth and inflation

The source of growth determines whether it adds to inflation pressure or relieves it.

Economic growth is an increase in real output. A rise in the value of sales caused only by higher prices is nominal growth, not proof of increased real production. In the short run, stronger spending can cause firms to use idle resources, increasing real output. Once production is close to capacity, further spending can push up prices more than output. Expansionary fiscal policy and lower rates can therefore create a growth–inflation conflict.

Growth driven by productive capacity can have a different effect. Effective training, reliable infrastructure or better machinery can increase output per input and reduce unit costs. Firms can meet more orders, so growth can coexist with lower inflation pressure. The policies use resources and take time: construction may initially add demand before a new transport link expands capacity. Actual output will not automatically increase if demand is too weak to use the additional capacity.

High or unpredictable inflation can itself harm future growth. Firms find it harder to judge costs and returns, discouraging investment. A policy that reduces persistent inflation may improve confidence over time even if it slows current spending. However, a sharp tightening when inflation is mainly due to a temporary supply shock can impose substantial output costs. Compare the short-run effect with the longer-run benefit rather than treating either as the only outcome.

In an illustrative economy with rising orders and delivery delays, an immediate spending stimulus may increase inflation. Targeted improvements to the bottleneck may support more sustainable growth, though they cannot instantly solve today's shortage. If output is falling because customers have stopped buying while factories stand idle, increasing spending may produce a larger real-output response. Capacity, the magnitude of the policy and its delay shape the trade-off.

Economic growth and environmental protection

Producing more can improve material living standards while increasing pressure on the environment.
