Outcome map

Point Content Key terms
1.6.1 Government spending to provide public service; taxation; constraints on public spending public services, tax, opportunity cost
1.6.2 Infrastructure provision; legislation; trade policy (membership of trading blocs, tariffs) infrastructure, law, trading bloc, tariff
1.6.3 Effect of interest rates on businesses and on consumer spending cost of borrowing, credit, saving
1.7.1 External factors: social, technological, environmental, political outside the firm’s control

The specification lists these points without defining them: the short definitions here are standard textbook definitions, not specification wording, and the treatment of taxes and laws is general. The command word definitions at the end are the specification’s own.

Briefest coverage in these notes: legislation (the specification names no particular laws, so it is kept general) and the political factor.

1.6.1 Government spending

Public services are provided by the government and paid for from public funds (for example health, education, policing).

Taxation raises the money. In general terms:

Tax falls on Effect on a business
Business profits Less profit kept for growth or owners
Workers’ incomes Less to spend, so weaker demand
Spending Higher customer price, so possibly lower sales

Constraints on public spending

  1. Tax revenue is limited.
  2. Borrowing must be repaid with interest.
  3. Opportunity cost: spending on one thing means not spending on another.
  4. A weak economy lowers tax receipts.

Reminder calculation. Sales tax: price × rate = tax; price + tax = customer price. At 12% on 85, the tax is 10.20 and the customer pays 95.20.

A bar for the $85 lamp is extended by a copper block of $10.20, the 12% sales tax, giving a customer price of $95.20. Two boxes show the retailer keeping its price so the customer pays more and may buy fewer, or cutting its own price so its margin shrinks.
A 12% sales tax raises the customer price from $85 to $95.20.
Horizontal bars show a 250 billion budget: health 75 (30%), education 50 (20%), transport 30 (12%), defence 20 (8%) and 75 for everything else. Transport is highlighted because a transport firm depends on it.
The four named areas total 175, leaving 75; a cut to transport puts a transport firm at risk.

1.6.2 How governments affect business activity

Policy What it is Likely effect on a business
Infrastructure Roads, rail, ports, power, communications Lower transport costs, reliability, access to markets and workers
Legislation Laws on consumers, employees, environment, competition Compliance costs, product changes, penalty risk, consumer trust
Trading bloc Group of countries trading on easier terms Cheaper access to a bigger market, but more competition
Tariff Tax on imports Dearer imports, protected home producers, revenue for government

Method in steps: working out a tariff

  1. Tariff = import price × tariff rate.
  2. New cost = import price + tariff.
  3. Compare with the home-produced price.
  4. Decide who gains (home producers, government) and who loses (importers, customers).

Reminder: 40 with a 15% tariff becomes 46.00, so a home product at 44 is now cheaper.

Bars compare a frame import at $40, the same import with a $6 tariff at $46, and a home frame at $44 marked by a dashed line. The tariff turns the import from cheaper to dearer; 12,000 frames give $72,000 of tariff.
A 15% tariff takes the import from $40 to $46, above the home price of $44.

1.6.3 Interest rates

Businesses. Higher rates mean higher interest on loans and overdrafts, lower profit, and fewer projects worth the borrowing cost. Lower rates reverse this.

Consumers. Higher rates make credit dearer and saving more attractive, so spending on credit-financed goods falls. Lower rates raise spending.

Rates rise Rates fall
Interest cost up Interest cost down
Investment delayed Investment more attractive
Consumer spending down Consumer spending up
Biggest hit: cars, furniture, houses Biggest boost: same big-ticket goods

Reminder calculation. Interest = loan × rate. 120,000 at 5% is 6,000; at 8% is 9,600. That is a rise of 3 percentage points but a 60% rise in the bill.

Two columns show yearly interest on a $120,000 loan: $6,000 at 5% and $9,600 at 8%, an extra $3,600. Two boxes contrast a rise of 3 percentage points with a 60% rise in the bill.
A 3-point rate rise lifts the interest bill by 60%.
A flow diagram shows a rate rise reaching consumers three ways: borrowing is dearer so credit buying falls, saving pays more so some people save instead of spending, and variable-rate debt costs more so less income is left. Consumer spending falls. Bars show a furniture shop falling from $80,000 to $72,000 a month, a drop of $8,000 or 10%.
Higher rates cut consumer spending three ways, taking a furniture shop from $80,000 to $72,000 a month.

1.7.1 External factors

Factor Examples Effect on decisions
Social Ageing population, changing tastes, ethical attitudes Product range, advertising, staffing
Technological Automation, online selling, new software Costs, sales channels, retraining
Environmental Pollution, waste, resource use, climate concern Packaging, energy use, reputation
Political Government policy, elections, stability Planning, tax, trade, laws

An external factor is something the firm cannot control but must respond to. Always link the factor to a specific decision: what to sell, where, at what price, how to produce.

A bar shows a $4.00 pack with a $0.30 recyclable packaging cost, 7.5% of the price. 50,000 packs make $15,000 a year. Three boxes show the responses: raise the price, absorb it, or gain sales if customers value it.
Recyclable packaging adds $0.30 a pack, $15,000 a year.

Method in steps: answering an analyse or evaluate question

  1. Identify the policy or factor in the stem (for example a rate rise, a new tariff, a social trend).
  2. Name the first effect on the business: costs, price, demand or the way it operates.
  3. Expand: say what that does to profit, cash flow, market share or customers.
  4. Use the numbers in the case. Work out the change before commenting on it.
  5. For evaluate, weigh the other side and say which effect is likely to be larger for this business and why. Give a supported conclusion.

Worked reminders

Tax on profit. A business makes a profit of 200,000 and the tax rate on profit is 20%. Tax = 40,000; profit after tax = 160,000. The business can use the 160,000 to reinvest or to pay owners.

Consumer borrowing. A shopper borrows 2,400 on a store card. At 6% the interest is 144 a year; at 9% it is 216. The difference of 72 is a small amount for one person, but it is repeated across many customers, so a retailer who sells on credit sees demand change.

Online sales share. A shop has sales of 640,000, of which 18% are online (115,200). If online sales grow by 25% they reach 144,000, which is 22.5% of the original total. A technological shift can change the sales mix quickly.

Wage costs and social change. A rise of 8% in an hourly wage of 5.50 gives 5.94. Social factors such as changing expectations of pay and conditions feed through to the cost of labour in the same way.

Linking the two sections

Government policy and external factors overlap. Environmental concern leads customers to demand greener products (social and environmental), and the government may respond with legislation (political). Technology can create an infrastructure need, such as better communications networks. When a question gives one factor, ask what others it triggers.

Starting point Possible chain
Rates rise Loan interest up, consumer credit costly, sales fall, profit falls
Tariff on imports Imported inputs dearer, price rises or margin falls, home rivals gain
New environmental law Compliance cost, product change, reputation gain
Better roads Lower delivery cost, wider customer reach, new competitors arrive

Must-know distinctions

  • Tariff versus tax on spending: a tariff applies to imports; a tax on spending applies to purchases generally.
  • Percentage points versus percentage change: from 5% to 8% is 3 points; the interest bill rises 60%.
  • Public service versus infrastructure: public services are provided to people; infrastructure is the physical network businesses use.
  • Legislation versus policy: a law must be obeyed; a policy is a plan of action that may use laws, taxes or spending.
  • Internal versus external: the firm controls its own prices and staff; it does not control social, technological, environmental or political factors.

Command words

The specification defines these as follows. Outline: give two linked points about a business concept or issue, placed in context. Explain: give a statement of fact with two further expansion points, with no context. Analyse: write an extended answer with expansion and exploration, placed in context. Justify: use the information provided to recommend one of two options. Evaluate: use knowledge of the content to reach a supported conclusion about a business situation.

Quick self-test

  1. State one way a government pays for public services.
  2. Give two constraints on public spending.
  3. Define infrastructure.
  4. A 25% tariff is placed on an import costing 52. Calculate the new cost.
  5. Name one benefit and one drawback of joining a trading bloc for a business.
  6. A business has a loan of 150,000. The rate rises from 6% to 9%. Calculate the extra yearly interest.
  7. Explain why higher interest rates may reduce sales of cars.
  8. Name the four external factors in 1.7.1.
  9. Sales fall from 9,600 to 8,160. Calculate the percentage change.
  10. Give one way a technological change could affect a small business.

Answers

  1. Taxation (it may also borrow).
  2. Any two of: limited tax revenue, borrowing must be repaid, opportunity cost, weak economy lowering tax receipts.
  3. The basic physical networks such as roads, rail, ports, power and communications that businesses rely on.
  4. 52 × 25% = 13.00, so the cost is 65.00.
  5. Benefit: cheaper access to a larger market. Drawback: more competition from other members.
  6. 150,000 × 9% = 13,500; 150,000 × 6% = 9,000; extra = 4,500.
  7. Cars are often bought on credit; dearer borrowing makes monthly payments higher, so fewer people buy.
  8. Social, technological, environmental, political.
  9. (8,160 − 9,600) ÷ 9,600 × 100 = −15%.
  10. For example, online selling opens a wider market without a shop; or the cost of new equipment strains its cash.

Where marks are usually lost

  • Describing a policy without naming its effect on the business in the question.
  • Treating a tariff as a tax on exports.
  • Giving only one side of a bloc, tariff or interest rate change.
  • Saying “interest rates go up so profit goes down” without explaining that the loan interest increases.
  • Mixing up percentage points and percentage change.
  • Listing the four external factors but not linking any to a decision.
  • Ignoring the context: a small local business and a large multinational feel the same policy differently.
  • In evaluate questions, stopping at analysis and not giving a supported conclusion.

Frequently asked questions

What are the constraints on government spending? Tax revenue is limited, borrowing has to be repaid with interest, every spending choice has an opportunity cost, and a weak economy can cut tax receipts just when demand for public services rises.

How do higher interest rates affect consumer spending? Borrowing on credit cards, car finance and mortgages costs more, saving becomes more rewarding and people with variable-rate debts have less to spend. Sellers of big-ticket goods bought on credit usually notice the change most.

What are the four external factors in Edexcel IGCSE Business? The 4BS1 specification names social, technological, environmental and political factors. They are outside a business’s control but still affect its decisions.

What is a trading bloc? A trading bloc is a group of countries that agree to trade with one another on easier terms, typically with lower or no tariffs between members, while outsiders may face barriers.
