Cambridge Syllabus Notes

6.1 External Influences – Economic

📚 What you’ll learn: How the government’s big‑picture economic decisions—like taxes, spending, and money supply—shape the way businesses plan and grow. Think of the economy as a giant playground: the government is the supervisor who can change the rules, and businesses are the kids who must adapt to keep playing.

Key Macroeconomic Policies That Influence Business

Fiscal policy – government spending & taxation.
Monetary policy – control of money supply & interest rates.
Exchange rate policy – how the value of the pound is managed.
Trade policy – tariffs, quotas, and trade agreements.

Impact of Fiscal Policy

📈 Government spending can boost demand. When the government builds roads or schools, businesses that supply materials and labour see more orders. 💸 Tax changes affect how much money consumers and companies keep. Lower corporate tax = more profit to reinvest. Higher income tax = less disposable income for shoppers.

Analogy: Imagine a lemonade stand. If the town council spends money on a new park, more people will visit the stand. If the council raises the lemonade tax, the stand’s profit shrinks.

Policy Change	Business Effect	Example
Increase in infrastructure spending	Higher demand for construction & materials	Local builders win contracts for new roads
Higher corporate tax rate	Reduced after‑tax profit → less reinvestment	Tech start‑up delays product launch

Impact of Monetary Policy

🏦 Interest rates influence borrowing costs. Lower rates mean cheaper loans for expansion; higher rates can squeeze cash flow. 💰 Money supply controls how much cash circulates. Too much money can spark inflation, hurting purchasing power.

Analogy: Think of a bank as a water tap. Turning the tap (interest rate) up or down changes how much water (money) flows to businesses.

Inflation formula: $\\displaystyle \\text{Inflation Rate} = \\frac{\\text{CPI}_{\\text{current}} - \\text{CPI}_{\\text{previous}}}{\\text{CPI}_{\\text{previous}}} \\times 100\\%$

Policy Tool	Business Impact	Illustration
Lowering the Bank Rate	Cheaper loans → more investment	Retail chain opens new store
Increasing the Money Supply	Risk of inflation → higher input costs	Manufacturing firm raises product price

Impact of Exchange Rate Policy

💱 A stronger pound makes imports cheaper but exports more expensive. A weaker pound can boost export sales but increase import costs. 📉 Businesses that rely on overseas suppliers must manage currency risk.

Analogy: Picture a currency as a game of tug‑of‑war. If the pound pulls hard (strong), it pulls foreign goods down (cheaper). If it pulls weak, foreign goods pull the pound down (expensive).

Exchange Rate Effect	Business Consequence	Example
Pound appreciates	Cheaper imports → lower costs	Tech firm buys cheaper chips
Pound depreciates	Higher export prices → lower demand	Clothing brand sees drop in overseas sales

Impact of Trade Policy

🚢 Tariffs raise the cost of imported goods, protecting domestic producers but potentially raising prices for consumers. 📦 Quotas limit the quantity of goods that can be imported, affecting supply and price. 🤝 Trade agreements can open new markets or create competition.

Analogy: Think of trade policy like a gate at a school cafeteria. A higher tariff is a gate that lets fewer foreign foods in, making local snacks more popular.

Policy Type	Business Effect	Illustration
Tariff on imported cars	Domestic car makers gain market share	Local dealership sells more home‑grown models
Free trade agreement with EU	Access to larger market → potential growth	Export‑oriented firm expands to France

Exam Tips for 6.1

Use real‑world examples (e.g., recent UK tax changes) to illustrate points.
Show cause‑and‑effect links: Policy → Business decision → Outcome.
Include at least one table or diagram to summarise effects.
Remember to discuss both positive and negative impacts.
Use the formula for inflation if asked to calculate or explain its effect.
