Key formulas

Four core objectives
Growth + Low unemployment + Stable prices + Balance of payments equilibrium
Learn these four as a checklist. Write each in your answer before discussing conflicts.
Economic growth (real)
Real growth % = (Real GDP this year − Real GDP last year) ÷ Real GDP last year × 100
Use real GDP, which removes the effect of price changes. Nominal GDP can rise from inflation alone.
Inflation rate
Inflation % = (Price index this year − Price index last year) ÷ Price index last year × 100
Measures the change in the general price level, for example through a consumer price index.
Current account balance
Current account balance = Exports − Imports (of goods and services, plus net income and transfers)
A current account deficit means payments exceed receipts. The overall balance of payments is the current account plus the capital and financial accounts, and it sums to zero. A current account deficit is therefore matched by a surplus on the capital and financial accounts.
Typical conflicts
Growth ↑ → unemployment ↓ but inflation ↑ and imports ↑; Inflation control ↑ → growth ↓ and unemployment ↑
These are common tendencies, not laws. Say 'may' or 'tends to' in written answers.
Budget balance
Budget balance = Government tax revenue − Government spending
A negative result is a budget deficit. A positive result is a surplus.
Borrowing need
Borrowing requirement ≈ Deficit for the period
The deficit is financed by borrowing, usually by issuing government bonds. Total accumulated borrowing is the national debt.
Expansionary fiscal policy
Spending ↑ and/or taxes ↓ → demand ↑
Aims to boost growth and employment. Risk: inflation and a larger deficit.
Contractionary fiscal policy
Spending ↓ and/or taxes ↑ → demand ↓
Aims to reduce inflation or the deficit. Risk: slower growth and higher unemployment.
Fiscal versus monetary policy
Fiscal = tax, spend, borrow (government). Monetary = interest rates, money supply (central bank).
Examiners often test which tool belongs to which policy.
Real interest rate (Fisher, exact)
(1 + nominal rate) = (1 + real rate) × (1 + inflation rate)
Use to find the real rate: (1 + nominal) ÷ (1 + inflation) − 1. The approximation real ≈ nominal − inflation is only rough.
Effect of a rate rise (rule of thumb)
Higher policy rate → higher borrowing cost → lower spending and investment → lower demand and inflation
A general tendency, not a guarantee. State it with 'tends to'.
Effect of a rate cut (rule of thumb)
Lower policy rate → cheaper borrowing → higher spending and investment → higher demand and inflation
Effect depends on business confidence and the time lag.
Direct quote meaning
Home currency per 1 unit of foreign currency
If a rate rises, the foreign currency has strengthened and the home currency has weakened. Always check which currency is the base.
Converting currency
Foreign amount × rate = home amount (when rate is home per foreign); divide when the quote is foreign per home
Multiply or divide depends on the quote. Check that the answer is sensible.
Percentage change in a currency
(New rate − Old rate) ÷ Old rate × 100
Apply it to the currency that is the base of the quote, otherwise the sign and size will be wrong.
Effect of home currency strength
Home currency stronger → exports dearer abroad, imports cheaper; weaker → the reverse
This is the rule most OT questions test.

Quick revision

  • Main macroeconomic aims: economic growth, low unemployment, stable prices and a sound balance of payments.
  • Fiscal policy means government decisions on taxation, spending and borrowing.
  • Expansionary fiscal policy raises spending or cuts taxes to increase demand; contractionary does the opposite.
  • A budget deficit arises when government spending exceeds its tax revenue.
  • Monetary policy works through interest rates, money supply and credit conditions, usually set by the central bank.
  • Higher interest rates tend to raise borrowing costs and reduce spending and investment.
  • Inflation is a sustained rise in general price levels; it reduces the real value of money.
  • A weaker home currency makes exports cheaper abroad but imports dearer.
  • A stronger home currency makes imports cheaper but can hurt exporters' competitiveness.
  • Trade barriers include tariffs and quotas; they protect domestic firms but can raise prices.
  • Competition policy aims to prevent monopoly abuse, cartels and harmful mergers.
  • Regulation can raise compliance costs but also protects consumers and market stability.

Common mistakes

  • Saying the four objectives can all be achieved together without difficulty. Fix: Always state that the government has limited tools and that improving one objective can worsen another.
  • Confusing nominal growth with real growth. Fix: Use real GDP for growth. If only nominal figures are given, adjust for inflation before judging growth.
  • Calling an interest rate change fiscal policy. Fix: Remember who acts. Interest rates and money supply are monetary policy. Taxes, spending and borrowing are fiscal.
  • Confusing the budget deficit with national debt. Fix: The deficit is the shortfall in one year. The national debt is the accumulated total of past borrowing.
  • Saying a rate rise increases demand because savers earn more. Fix: Overall, a rate rise tends to reduce spending as borrowing costs and incentives to save outweigh extra interest income. Say 'tends to'.
  • Confusing monetary policy with fiscal policy. Fix: Monetary policy is run by the central bank (rates, money supply, credit). Fiscal policy is run by government (taxes and spending).
  • Multiplying when you should divide in a conversion. Fix: Write the quote as '1 base = X other'. To get the other currency, multiply by X. To get the base, divide by X.
  • Saying a higher exchange rate always means the home currency has strengthened. Fix: Check the base. If the quote is home per foreign, a higher number means the home currency has weakened.
  • Treating regulation and competition policy as the same thing. Fix: Competition policy keeps markets competitive. Regulation is the wider set of rules on how firms behave, including price controls and consumer protection.
  • Saying a monopoly is always illegal. Fix: Having market power is not always unlawful. Policy usually targets the abuse of a dominant position or anti-competitive agreements, though rules vary by country.

Exam tips

  • In a written answer, always show the conflict explicitly. Naming the four objectives alone earns little.
  • In objective test questions, look for the option that shows one objective improving and another worsening. Options where everything improves are usually wrong.
  • Use the scenario facts. If the question mentions imports, exchange rates or rising prices, link your answer to those details.
  • When a calculation is needed, check whether the figures are real or nominal before working out growth.
  • Keep answers short and structured: objective, policy effect, side effect, business impact.
  • Always state whether a measure is fiscal or monetary. Marks are often lost on this alone.
  • In written answers, use the pattern: policy, effect on demand or cost, effect on the business, conclusion.
  • Link tax changes to investment appraisal. A change in corporate tax or capital allowances alters after-tax cash flows in NPV.
