Explain economic policy and business effects
Trace government intervention and macroeconomic changes through demand, costs and business decisions while keeping effects conditional.
Cambridge International AS & A Level Business 9609, 2026–2028 syllabus and 2029 syllabus, section 6.1.2. Apply legal, economic and political examples to the relevant country and date.

Before you begin
- Use the lesson's stated business context and distinguish evidence from assumptions before recommending a response.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Which policy directly changes government spending or taxation?
What you will learn
- Explain why governments help or constrain businesses
- Relate macroeconomic objectives to business conditions
- Trace monetary, fiscal, supply-side and exchange-rate policy effects
Governments intervene for different reasons
Support for enterprise may include infrastructure, training, grants or advice; constraints may include taxes, regulation or limits on harmful activity. Government action can also address market failure, such as external costs or inadequate information. Each intervention uses resources and can create unintended effects.
A business should identify the market failure or policy goal, the instrument used and which firms or stakeholders are affected. A subsidy may lower costs for an eligible firm but not for competitors; a regulation may protect the public while raising compliance costs.
Macroeconomic conditions change sales and costs
Governments commonly seek low unemployment, low inflation and economic growth. Changes in income, employment, prices and confidence can affect demand, hiring and input costs. A firm serving different customer groups may experience these changes differently.
Monetary policy, such as an interest-rate change, can affect borrowing costs, saving and demand. Fiscal policy changes government spending or taxation. Supply-side policies aim to improve productive capacity or efficiency. Exchange-rate policy affects the relative price of imports and exports. The direction and size of the business effect depend on the policy, time lag, exchange exposure and wider conditions.
Pause and explain
A rise in interest rates may most directly increase which cost for a business with variable-rate borrowing?
Worked example
A central bank raises interest rates while household debt is high. Explain one possible effect on a furniture retailer and why it is not certain.
Show the worked solution
- Higher rates can raise repayments on variable-rate borrowing.
- Households may reduce spending on financed or deferrable purchases.
- The retailer's own debt, customer mix and other conditions affect the outcome.
Answer The retailer may face higher interest costs if it has variable-rate debt, while customers may postpone furniture purchases as borrowing becomes more expensive. The effect is uncertain because the retailer may have fixed-rate finance, customers may have savings, and employment, confidence and rival prices also matter.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Government increases infrastructure spending during weak demand. Explain one possible benefit and one risk for a construction supplier.
Give me a hint
Link public spending to orders, then consider financing, timing or capacity effects.
Compare my reasoning
- Infrastructure projects may create demand for construction inputs.
- More orders can raise capacity use and revenue.
- Delays, taxes, inflation or project selection may limit the result.
The supplier may gain orders as public projects buy materials, potentially improving capacity use and revenue. The benefit depends on project timing and eligibility; if resources are scarce, input prices may rise, and future taxation or budget limits could affect later demand.
Look for these in your work
- Direct demand channel is explained
- Business outcome is linked
- A material risk is included
An economy experiences falling unemployment but accelerating inflation. Explain why a manufacturer may face both stronger sales and higher costs.
Give me a hint
Connect employment and income to demand, then inflation to inputs and wages.
Compare my reasoning
- More people in work can increase household income and demand.
- Inflation can raise material, energy and wage costs.
- The net profit effect depends on pricing power and productivity.
Higher employment may support household spending and the manufacturer's sales. At the same time, inflation can raise wages, energy and materials. Profit depends on whether the firm can pass costs on without losing customers and on its productivity and contracts.
Look for these in your work
- Demand effect is traced
- Cost effect is traced
- Net effect is evaluated conditionally
An exporter buys most inputs in a foreign currency. Explain how an exchange-rate change could affect it and what information is needed before recommending a response.
Give me a hint
State whether the domestic currency strengthens or weakens and identify both sales and input exposures.
Compare my reasoning
- A weaker domestic currency may improve export price competitiveness.
- It can also raise the domestic cost of imported inputs.
- Check invoice currencies, contract timing, hedges and rivals' exposure.
A weaker domestic currency may make exports cheaper to foreign buyers, but it can raise the cost of imported inputs. The business should check which currency it invoices in, when prices reset, existing hedges and competitors' exposure before changing prices or sourcing.
Look for these in your work
- Both revenue and cost channels are explained
- Direction is explicit
- Decision evidence is identified
Common mistakes
- Confusing monetary policy with fiscal policy
- Assuming every policy change affects all firms in the same way
- Claiming an objective is achieved merely because a policy was announced
What can you explain now?
Which policy directly changes government spending or taxation?
Compare with the explanation
Fiscal policy
Fiscal policy uses public expenditure and taxation; monetary policy uses tools such as interest rates.
