New emphasis in the 2027 syllabus; supply-side policy is now examined as a distinct policy alongside fiscal and monetary policy. Guidance based on specimen materials.

Because supply-side policy raises capacity, it can help with several aims at once.

Economic growth. More and better resources mean the economy can produce more, raising real output over time.
Low inflation. A larger productive capacity lets output grow without the shortages that cause demand-pull inflation, and lower firm costs ease cost-push inflation.
Low unemployment. Education, training and better incentives improve workers' skills and willingness to work, cutting structural and frictional unemployment, while expanding firms hire more staff.
Balance of payments stability. Lower costs and higher productivity make exports more price-competitive, which can improve the current account.

The catch in every case is the time lag. Supply-side measures rarely change anything quickly, and some are expensive or politically difficult. A government usually combines them with fiscal and monetary policy rather than relying on them alone.

Exam tip

Analyse how supply-side policy measures could reduce unemployment (6 marks)

What comes up: a 6-mark Analyse question on how supply-side policies cut unemployment. The mark scheme credits identifying a measure and then explaining the link in steps, so each point must travel two or three stages.

Write: chain two or three of the following. (1) Education and training raises workers' skills (1), increasing their productivity and occupational mobility (1), which reduces structural unemployment (1). (2) Infrastructure spending improves geographical mobility (1), so workers can reach jobs in other areas (1), reducing structural unemployment (1). (3) Lower income tax or reduced unemployment benefit widens the gap between work and benefits (1), increasing the incentive to find work quickly (1), reducing frictional unemployment (1). (4) Privatisation or deregulation can raise efficiency and reduce firms' costs (1), enabling firms to afford more workers (1).

Watch out: the mark scheme does not reward the same point twice, so keep each chain distinct. A lower interest rate counts only if you tie it explicitly to encouraging firms to invest and expand; on its own it is monetary policy, not supply-side.
