2.6 macroeconomic objectives and policies

economic growth

Pursuing sustainable, long-run growth (around 2–2.5% for the UK)

prioritizing growth may harm the environment or increase inequality.

low unemployment

Close to full employment; UK target roughly 3–5% to account for frictional/structural unemployment

inflation

– UK target is 2% (measured via CPI).

current account

Sustainable balance of payments on the current account

Greater equality

Reducing inequality through redistributive policies; measured with tools like the Gini coefficient or Lorenz curve

what is monetary policy

• Deliberate action by the government designed to influence the supply of money in the economy

• The Bank of England (BoE) controls monetary policy in the UK

what does quantitative easing achieve

• Stimulate the economy, particularly during a recession

• Possible multiplier effects

• Likely to be used when base rate changes can’t achieve objectives on its own

intrerest rates

Managed by the Bank of England’s Monetary Policy Committee (MPC).

Raising rates tampers AD; cutting rates stimulates consumption, investment, weakens the pound, and supports net trade

explain how a rise in englands base rate may lead to a fall in inflation

1. BoE raises base rate

2. This increases the cost of retail banks’ borrowing from the BoE

3. Retail banks raise their own interest rates

4. Higher interest rates encourage saving and discourage spending and investment (C + I)

5. Less spending reduces the amount of aggregate demand in an economy

6. This reduces inflation (the rate at which      average prices increase)

bank of england base rate limitations

• Time lags

  • It takes months for interest rate changes to affect spending, investment, and inflation.

  Liquidity trap

  • When interest rates are near zero, further cuts have little to no effect.

Only tackles demand-side issues

• It can’t solve cost-push inflation (e.g. rising energy prices or supply chain shocks).

define the term “price level”

the avergae price of goods and services in an economy indicating inflation or deflation

define the term “interest rate”

is the percentage charged on borrowed money or earned on savings reflecting the cost of credit or the return on investment over a specific time period

Explain how the use of Quantitative easing leads to greater real output and higher inflation

1. BoE creates money

2. BoE buys govt bonds from banks

3. Banks more inclined to lend to firms and individuals

4. Lowers interest rates

5. Greater lending boosts C + I and so AD

6. Extra spending/AD creates a stimulus to help an economy recover from recession

limitations of quantitative easing

• Trade-offs of macroeconomic objectives

• Potential long-term inflationary pressure due to increased amount of money in the economy

• Information problem – how much QE?

• ‘Zombie’ banks & businesses – propped up by cheap credit

direct VS indirect taxes

• Direct: Income tax, corporation tax, etc.

• Indirect: VAT, excise duties—affect producers and consumers differently

• Limitations: Time lags, imperfect information, , uncertain multiplier effects, high-interest environments dampen effectiveness, long-term debt concerns

explain the distinction between a government budget deficit and surplus

-if total government spending exceeds total revenue from taxation there is a budget deficit

-if total government spending is less than total revenue from taxation there is a budget surplus

supply side policies

policies aimed at increasing the productive potential of an economy and moving the supply curve to the right

investing in education, infrastructure, and technology, and reducing business costs through deregulation and tax cuts

rightward shift of LRAS:

economic growth & inflationary presssures

• Rapid increases in aggregate demand (particularly from consumer spending) are likely to lead to rising inflation

  • i.e. when growth in consumer demand is high, the supply constraints lead to rising prices

  • Rising AD causes spare capacity to fall which creates greater scarcity in the economy

macroeconomic trade offs

• Not all economic objectives are likely to be achievable simultaneously

• When success in one objective compromises the ability to meet another objective, it is described as a trade-off

economic growth & infaltion diagram

evaluation for economic growth & inflation

• Supply-side improvements will increase LRAS leading to an improvement in both

• Anything improving technology, skills, productivity will lower costs of production while also increasing real output

(This is a really good point of evaluation, but can’t be used if the question is about demand-side policies)

diagram for evaluation of economic growth & inflation

evaluation 2 for economic growth & inflation

• Increases in AD when there is significant amount of spare capacity can lead to higher real output (Y1 to Y2) without creating significant increases in the price level

• The spare capacity means that output can increase without creating significant competition for factors of production and goods and services

falling unemployment & inflation

• Falling unemployment tends to lead to higher inflation

  • As unemployment falls a shortage of labour means workers’ bargaining position is stronger

🡪 allows workers to claim higher wages

🡪 leads to higher business costs

🡪 leads to higher prices

The phillips curve

economic growth & current account

• If economic growth is based on consumer spending it is likely to worsen the current account

  • Rising spending (C) causes a rise in AD (actual growth)

  • A portion of the extra spending will be on imported goods

evaluation of economic growth & current account

• It depends on the cause of the economic growth

  • If economic growth is ‘export-led’ then these objectives could be achieved simultaneously

  • Rise in both AD and the current account as a result of a rise in the value of exports (X-M)

economic growth VS fiscal deficit reduction

• Attempts to reduce the fiscal deficit involve cutting spending and/or raising taxes

• Both have a withdrawal effect of the circular flow of income

• The result is likely to be a fall in aggregate demand, reducing GDP

• The budget deficit is reduced, but as a result economic growth suffers

evaluation of economic growth and fiscal reduction

Evaluation

• When GDP increases, extra spending increases tax revenues (e.g. VAT)

• More people in employment means that fewer people need to be given unemployment benefits (automatic stabilisers)

• So, as a result of economic growth the budget deficit improves

economic growth & environment

Evaluation

• If economic growth is based on technological advance then it could lead to cleaner technology which reverses environmental damage

  • Electric cars

  • Solar/wind energy

explain the tools involved in fiscal policy

• Government spending (G) and taxation (T). Can be expansionary or contractionary.

• Direct taxes: Income tax, corporation tax; Indirect taxes: VAT, excise duties.

• Budget positions: deficit or surplus.

fiscal policy evaluation

time lags - when the government makes spending and taxation decisions there is a time lag before the effects are seen

trade off - if the government tries to influence AD it cannot achieve all macroeconomic objectives - AD leads to a fall in unemployment but a rise in inflation

interventionist policies

• Aim to correct market failures by active government involvement in improving economic performance.

• Examples:

  • Education and training investment

  • Infrastructure spending

  • Subsidising R&D

  • Regional development grants

➡ Goal: Raise productivity and long-term growth by improving resources and capacity.

market based policies

Market-based supply-side policies aim to increase the efficiency and productivity of the economy by reducing government intervention and allowing free-market forces to operate more effectively.

They shift the Long-Run Aggregate Supply (LRAS) curve to the right by making markets more competitive, flexible, and efficient, thus boosting the economy’s productive potential.

incentive market based policies

Encourage work, investment, and entrepreneurship

• ✅ Lower income tax:
  → Increases the post-tax return to work
  → Encourages labour participation (especially among secondary earners)
  → Incentivises effort and productivity

  🧠 A* Tip: Refer to the Laffer Curve — lowering tax rates might increase tax revenue if disincentives at high tax rates are severe.

• ✅ Lower corporation tax:
  → Increases retained profits
  → Encourages investment in capital, R&D

  Example: UK cut corporation tax from 28% (2010) to 19% (2017) to boost business growth.

• ✅ Reduced welfare benefits:
  → Reduces the replacement ratio (benefits vs wages)
  → Makes employment more attractive

  Evaluation: Can worsen inequality and poverty — depends on availability of jobs and upskilling.

labour market reforms

• Deregulation of labour laws:
  → Easier hiring/firing = more flexible employment
  → Encourages firms to take on workers

  Evaluation: May reduce job security and wages → worsens working conditions.

• ✅ Reduction in trade union power:
  → Prevents excessive wage demands
  → Allows wages to reflect productivity

  A* Application: UK saw this post-1980s with Thatcher’s trade union reforms.

demand side policies

policies designed to influence the level of AD

Monterary policy - conducted by the bank of england

fiscal policy - conducted by the treasury

Diagram - impact of a successful demand side policy in moving an economy from recession to full capacity

interventionist

• Human Capital: Investment in education, training, healthcare

• Infrastructure: Transport, digital networks, public capital

• Goal: Address market failures and enhance productive capacity → shift LRAS right

• Evaluation: Long-term payoff vs high costs, implementation time, potential inefficiency

the purpose of fiscal policy

• To influence the level of economic activity

  • Spending and taxation levels can have an impact on the aggregate demand of the economy

    • E.g. greater spending by the government leads to a rise in AD and so a greater level of economic activity

automatic VS discretionary spending

• Automatic

  • Some spending and taxation changes happen automatically as an economy moves through the economic cycle

• Discretionary

  • Sometimes government makes active decisions to change the level of spending - known as discretionary changes

automatic stabilisers

• In a recession:

  • more people out of work automatically leads to more government spending on unemployment benefits

  • Less consumer spending automatically results in less VAT & income tax being collected, reducing the amount of withdrawals from the economy

• These create a net injection into the economy

discretionary spending in a recession

• In a recession:

  • Government might actively spend money or reduce taxes to create an injection into the economy

• Examples:

  • Spending in 2008/09 in response to recession

  • Covid response in 2020/21

exspansionary fiscal policy

fiscal policy influencing economic activity

• Fiscal policy can be used as part of ‘demand management’

  • When AD grows too much, adjustments in fiscal policy can prevent the boom becoming too much of a ‘bubble’

  • When AD falls, greater spending or lower taxes can help to prevent a deep recession

  • Sensible use of fiscal policy might help ‘smooth’ the economic cycle

contractionary fiscal policy

contractionary fiscal policy

• Contractionary fiscal policy

  • Spending and taxation by government with the aim of decreasing the level of AD

    • Less spending

    • Higher taxes

    • Decrease in a budget deficit/increase in a budget surplus

expansionary fiscal policy multiplier effect
