External influences on business activity: IGCSE Business Studies Complete Notes

Businesses do not operate in a vacuum

Every decision a business makes happens inside a bigger picture. Interest rates rise and borrowing gets expensive. A government raises corporation tax. A pressure group launches a social media campaign against plastic packaging. A competitor in another country undercuts your price because their currency just dropped 15%. None of these events are under the business's control, but all of them change how it operates, what it earns and sometimes whether it survives.

The IGCSE Business Studies syllabus groups these forces under "external influences on business activity." This section carries serious weight in the exam. Questions on the business cycle, government policy and globalisation appear regularly in both Paper 1 and Paper 2, and they almost always require you to apply the theory to a specific business scenario rather than just recite definitions. Here is what you need to know, stripped down to what actually earns marks.

The business cycle

Economies do not grow in a straight line. They move through a repeating pattern of four stages:

After a slump, the economy gradually recovers and moves back into growth, starting the cycle again. The key exam skill is not memorising the four stages but explaining how a specific business would be affected at each stage. A supermarket selling basic groceries reacts differently to a recession than a company selling luxury holidays.

Government influence on the economy

Governments have economic objectives that directly affect businesses. The main ones tested in the IGCSE syllabus are:

• Increasing GDP: growing the economy to raise living standards
• Low inflation: keeping price rises stable so consumers can plan spending
• Low unemployment: ensuring most people who want to work can find jobs
• Stable balance of payments: keeping the value of exports roughly in line with imports

To hit these targets, governments use two main tools:

Fiscal policy: taxes and government spending

If the government raises income tax, consumers have less disposable income, so they spend less. Businesses selling non-essential goods see demand drop. If the government raises corporation tax, businesses keep less profit after tax, reducing the funds available for reinvestment. The reverse also applies: cutting taxes puts more money into pockets and encourages spending.

Government spending works the other way round. If the government builds new hospitals, roads or schools, it creates jobs and puts money into the economy. Firms in construction, engineering and supply chains benefit directly. The knock-on effect ripples outward as those newly employed workers spend their wages.

Interest rates

The interest rate is the cost of borrowing money and the reward for saving it. When interest rates rise:

• Consumers with mortgages and loans pay more each month, leaving less for other spending
• Saving becomes more attractive, so people spend less
• Businesses face higher costs on loans and overdrafts, making expansion more expensive
• Demand falls, particularly for big-ticket items bought on credit (cars, houses, appliances)

When interest rates fall, the opposite happens. Borrowing is cheaper, saving is less rewarding, and both consumers and businesses are more willing to spend and invest.

Environmental concerns and ethical issues

This subtopic is one of the most heavily examined in the entire IGCSE Business Studies course. The syllabus treats environmental and ethical issues as both constraints (things that limit what a business can do) and opportunities (things that create new markets or competitive advantages).

Environmental concerns as constraints

• Legal regulations force businesses to limit emissions, dispose of waste safely and reduce pollution. Non-compliance leads to fines, legal action and reputational damage.
• Packaging regulations require businesses to reduce, reuse or recycle materials, increasing production costs.
• Carbon taxes and emissions trading schemes add costs to businesses that rely on fossil fuels.

Environmental concerns as opportunities

• Growing consumer demand for sustainable products creates new markets. Organic food, electric vehicles and recycled fashion all exist because customers are willing to pay for environmentally responsible alternatives.
• Energy efficiency reduces long-term costs. A factory that invests in solar panels or LED lighting pays more upfront but saves on electricity bills for years.
• A strong environmental reputation builds brand loyalty. Customers, especially younger demographics, increasingly choose brands that align with their values.

Ethical issues

Ethics in business covers fair treatment of workers, honest advertising, responsible sourcing and operating with integrity even when no law requires it. A business that pays suppliers in developing countries a fair price (fair trade) earns customer trust and media goodwill. A business caught using child labour in its supply chain faces boycotts and long-term brand damage regardless of whether it broke a specific law.

Pressure groups are organised bodies of people who campaign to influence business behaviour on environmental or social issues. They use tactics including protests, petitions, social media campaigns and lobbying politicians. Businesses must decide whether to resist, negotiate or adapt.

Globalisation

Globalisation is the increasing interconnection of the world's economies through trade, investment, technology and the movement of people. For IGCSE purposes, you need to know why it is happening and how it affects businesses.

Why globalisation is increasing:

• Improvements in transport (containerisation, cheaper air freight) make it cheaper to move goods across borders
• The internet and digital communication allow businesses to operate, sell and manage across time zones
• Trade agreements and organisations (e.g. the World Trade Organization) reduce tariffs and barriers
• Multinational companies actively seek cheaper production locations and larger markets

Opportunities for businesses:

• Access to larger markets increases potential sales volume
• Sourcing raw materials or components from lower-cost countries reduces production costs
• Access to a wider talent pool for recruitment

Threats for businesses:

• Increased competition from foreign firms that may have lower costs
• Local businesses may be unable to compete on price with large multinationals
• Cultural differences create challenges when marketing products in new countries
• Exchange rate fluctuations make costs and revenues unpredictable

Multinational companies (MNCs)

A multinational company operates in more than one country. It has its headquarters in one country (the home country) and production or sales operations in others (host countries). Examples include Unilever, Toyota, Samsung and Nestle.

Why MNCs grow:

• To access new markets and increase sales
• To reduce costs by producing in countries with cheaper labour, land or raw materials
• To avoid trade barriers by manufacturing inside the market they want to sell in
• To spread risk across multiple economies (if one country enters recession, sales in another may compensate)

Exchange rates

The exchange rate is the price of one currency expressed in terms of another. When the exchange rate changes, it affects any business that imports materials or exports goods.

If the domestic currency strengthens (e.g. 1 GBP now buys 1.40 USD instead of 1.30 USD):

• Imports become cheaper because each unit of your currency buys more foreign currency. A UK business importing American components pays less in pounds.
• Exports become more expensive for foreign buyers because they need more of their currency to buy yours. A UK exporter's products cost more in dollars, so sales abroad may fall.

If the domestic currency weakens (e.g. 1 GBP now buys only 1.20 USD):

• Imports become more expensive. The same American components now cost more in pounds.
• Exports become cheaper for foreign buyers. The UK exporter's products look like better value in dollars, so overseas demand may rise.

The simplest way to remember this: a strong currency is good for importers and bad for exporters. A weak currency is good for exporters and bad for importers.

Worked example

A British furniture company imports timber from Canada at a cost of 50,000 Canadian dollars per shipment.

At an exchange rate of 1 GBP = 1.70 CAD: the cost in pounds = 50,000 / 1.70 = 29,412 GBP.

If the pound weakens to 1 GBP = 1.50 CAD: the cost in pounds = 50,000 / 1.50 = 33,333 GBP.

The same shipment now costs the company an extra 3,921 GBP. If timber makes up a large share of total costs, this exchange rate movement could wipe out the firm's profit margin on several product lines. The business must decide whether to absorb the cost, raise prices, or find a domestic supplier.

Entering foreign markets

When a business decides to sell in a new country, it faces both opportunities and problems that the IGCSE syllabus expects you to evaluate.

Opportunities: larger customer base, potential for higher sales and profits, reduced dependence on one market, ability to extend the product life cycle (a product declining in one market may be new in another).

Problems: language and cultural barriers make marketing harder, different legal systems require compliance with unfamiliar regulations, exchange rate risk makes revenue unpredictable, competition from established local brands that understand the market better, logistical challenges of transporting goods across borders.

Common exam mistakes

1. Describing the business cycle stages without applying them. The question will give you a specific business in a specific stage. Do not just define "recession." Explain what happens to that bakery chain, that car dealership, that luxury hotel during a recession and why.
2. Confusing fiscal policy with monetary policy. Fiscal policy is about government spending and taxation. Monetary policy is about interest rates. They are different tools with different mechanisms. Use the correct term.
3. Writing one-sided answers on environmental issues. If the question asks you to "discuss" or "evaluate" whether environmental regulations help or harm a business, you must cover both sides. Regulations increase costs (constraint) but can also create new product opportunities and build brand loyalty (opportunity).
4. Stating MNC advantages without linking to the case study. Do not write a generic list. If the case study describes an MNC opening a factory in a developing country, link your points to that specific context: how many jobs, what type of jobs, what local businesses might benefit or suffer.
5. Getting exchange rate effects backwards. Students regularly mix up whether a strong currency helps importers or exporters. Use the rule: strong = cheap imports, expensive exports. Weak = expensive imports, cheap exports. Write it on your exam paper before tackling the question.
6. Ignoring the "how businesses respond" part. Many questions ask not just what happens when interest rates rise, but what a business could do about it. Answers might include delaying expansion, reducing stock levels, renegotiating loan terms, or switching from variable-rate to fixed-rate borrowing. The response is where the higher marks sit.

Self-check questions

1. Name the four stages of the business cycle and explain how a restaurant chain might be affected during a recession compared to a discount supermarket.
2. A government raises interest rates from 2% to 4%. Explain two effects this might have on a small business that relies on an overdraft to manage cash flow.
3. A clothing company is criticised by a pressure group for using factories with poor working conditions. Explain one short-term cost and one long-term benefit of the company switching to ethically certified suppliers.
4. A UK electronics manufacturer exports 60% of its output to the United States. The pound strengthens against the dollar. Explain how this affects the manufacturer and suggest one action it could take in response.
5. Evaluate whether a multinational car manufacturer opening a factory in a developing country is likely to have a positive or negative overall impact on that country's economy.
