What is Fiscal, Monetary & Supply-Side Policy?

Governments and central banks use a range of policies to manage the economy and achieve their macroeconomic objectives. Fiscal policy involves the use of government spending and taxation to influence aggregate demand. Monetary policy, typically controlled by a central bank like the Bank of England, uses interest rates and the money supply to manage AD. Supply-side policies aim to increase the economy's productive potential (shifting LRAS to the right).

Board notes: This is a major topic for all A-Level boards (AQA, Edexcel, OCR), bringing together the application of the AD/AS model. All boards expect students to be able to evaluate the strengths and weaknesses of each type of policy in achieving various macroeconomic objectives. Edexcel and AQA often include questions on the conflicts between policy objectives, such as the trade-off between unemployment and inflation.

Worked example

Common mistakes

• 1Confusing fiscal and monetary policy. Fiscal policy is conducted by the government (e.g., the Chancellor's budget), involving spending and tax decisions. Monetary policy is conducted by the central bank and focuses on interest rates and the money supply.
• 2Assuming that policy changes have an immediate effect. All macroeconomic policies are subject to significant time lags. For example, it can take up to 18-24 months for the full effect of an interest rate change to be felt in the economy.
• 3Thinking that supply-side policies are a quick fix for economic problems. While supply-side policies can increase long-term growth, they often take a long time to have an effect (e.g., improvements in education) and can be expensive and politically difficult to implement.

Frequently asked questions

• How does the Bank of England use interest rates to control inflation?

  If inflation is above its 2% target, the Bank of England can raise interest rates. This makes borrowing more expensive and saving more attractive, which reduces consumer spending and business investment, dampening aggregate demand and reducing demand-pull inflationary pressure.

• What is the difference between market-based and interventionist supply-side policies?

  Market-based supply-side policies aim to free up the market, such as privatisation, deregulation, and cutting trade union power. Interventionist policies involve the government taking an active role, such as increasing spending on education and training, or investing in infrastructure.
