6.2.1 Environment and ethics at a glance

How business harms and helps the environment

  • Harm: global warming from burning fossil fuels, air and water pollution, noise, waste, loss of habitats, use of non-renewable resources.
  • Help: renewable energy, recycling, less packaging, longer-lasting products, local sourcing.
Environmental impacts shown as a car, recycling arrows, a bin and a smoking factory; sustainability shown as a thermometer and a tree stump. A banner says each is a trade-off with profit.
Environmental impacts and sustainability both involve weighing costs now against benefits later.

Externalities: spot the difference

  • The test: who pays or gains? If it is someone outside the business and its customers, it is external.
  • A factory’s higher wage bill is private. A river polluted by the factory is an external cost.
  • Do not credit the business with its own sales or profit as an external benefit.
A factory points to two panels. External costs: noise and congestion for residents, warm water that harms river life. External benefits: 90 jobs and a new road. A box says wages, materials and own sales are private, not external.
External costs and benefits fall on people outside the transaction, unlike the firm's own costs.

Sustainable development: ways a business can contribute

  1. Switch to renewable energy.
  2. Cut waste and recycle materials.
  3. Use resources from managed sources.
  4. Design products to be repaired, not thrown away.
  5. Reduce transport distances.
A balance of needs today against future needs, with six business actions: renewable energy, cut waste, recycle, managed resources, products that last and shorter transport.
Sustainable development means both present and future needs are met.

Responding to pressure and opportunity

Reason to respond Cost or limit of responding
Avoid lost sales from boycotts or bad publicity New equipment and training
Meet customer demand for green products Higher input costs
Follow the law and avoid fines May raise prices against rivals
Attract staff and investors Benefits may take time to appear

Pressure group methods: publicity, petitions, protests, calls for boycotts, lobbying government.

Flow from pressure group methods to bad publicity, falling sales and a business response, with reasons for and costs of responding.
How pressure groups push firms to respond, and what responding costs.
  • Purpose: stop harm and set the same minimum standard for all.
  • Business effect: higher costs, but fewer fines and a better reputation.
  • Keep descriptions general. Say “a pollution control” and explain what it does; do not make up the name of a law.
Two to-scale bars: filter Rs 180,000 against fine Rs 250,000, Rs 70,000 more, plus unpriced damage to its name.
Fitting the filter is Rs 70,000 cheaper than the fine, before reputation damage.
Three bands: ethics (a choice: charitable giving, fair prices to suppliers, religious observance) above a line marking the legal minimum; law (a requirement: safe workplace, national minimum wage, consumer protection); and breaking the law, which brings consequences of non-compliance.
Law is what a business must do; ethics is what it chooses to do beyond that.

Profit versus ethics

Issue Profit-first choice Ethical response
Child labour Cheapest supplier, no checks Audit suppliers, stop buying where it is found
Supplier prices Squeeze the price down Pay a fair price for a stable supply
Honest information Overstate product claims Tell the truth, accept lower short-term sales

Judgement tip: an ethical choice often costs money now but can protect the brand, supply and customer trust.

Three bars of profit: 1,800,000 now, 900,000 if growers get a fair price of 345 per kg, and 1,500,000 if the firm also raises its price by 5 percent.
Paying a fair price cuts profit, which is the profit-versus-ethics conflict.
A level balance scale with a question mark on the pivot: coins on the left for higher costs and lower margin, heart, star and box on the right for loyalty, reputation and reliable supply. The judgement depends on whether customers value it enough.
Ethical action has a cost and a benefit, and the judgement depends on the business and its customers.

6.3.1 Globalisation

  • Causes: cheaper transport, faster communication, lower trade barriers, growth of MNCs.
  • Opportunities: bigger markets, cheaper inputs, spread of risk.
  • Threats: more competition, lost home sales to cheap imports, need to adapt to local tastes.

Tariff versus quota

Tariff Quota
What it is Tax on imports Limit on quantity imported
Effect on price Imports cost more Imports become scarce, so prices may rise
Government gain Raises tax revenue None directly
Why used Protect local firms and jobs, protect new industries, raise money Protect local firms and jobs

Price with a percentage tariff = import price × (1 + tariff rate). Example: a 25% tariff on a Rs 800 item gives 800 × 1.25 = Rs 1,000.

Bars show local cloth at 560, imports at 500, and imports at 600 after a 20 percent tariff adds 100. A gate picture shows a quota as a hard limit on quantity, with box numbers illustrative.
A tariff raises the price of imports; a quota limits their quantity.
Four causes lead into one world market; below are four opportunities and four threats for a business.
Why globalisation happens and its opportunities and threats.

6.3.2 Multinationals

  • Why they grow: new markets, lower costs, avoid tariffs by producing locally, spread risk, economies of scale.
  • Stakeholders: shareholders may gain; home workers may lose jobs; host-country workers gain jobs; local suppliers gain contracts.
Host country gains Host country loses
Jobs Local businesses lose sales
Exports Repatriated profits
More choice Pollution or poor conditions possible
Investment Jobs can leave quickly

Method in steps for a host-country question:

  1. State the effect (job, export, choice, investment, lost sales, repatriation).
  2. Link it to the case study.
  3. Say who is affected.
  4. For evaluate, say which effect is larger and why.
A bar splits 8,000,000 profit into 6,000,000 repatriated (75 percent) and 2,000,000 kept. A second bar splits 420 jobs into 300 local (71 percent) and 120 incoming.
A host country gains jobs and exports but loses much of the profit.

6.3.3 Exchange rates

Home currency Exporter Importer
Appreciates Foreign price rises, less competitive Inputs cheaper, costs fall
Depreciates Foreign price falls, more competitive Inputs dearer, costs rise

Exchange rate calculations are not assessed, so learn the direction of each effect and the reason.

The pound weakens from 1.50 to 1.25 dollars. A 100 pound export costs the US buyer 150 then 125 dollars (cheaper, helps the exporter). A 100 dollar import costs the UK buyer 66.67 then 80.00 pounds (dearer, hurts the importer). If the pound strengthens, the effects reverse.
A weaker home currency helps exporters and hurts importers; a stronger one reverses this.
The pound falls from 200 to 180 yen, so a 36,000 yen motor rises from 180 to 200 pounds (11.1 percent), and an order of 4,000 motors costs 80,000 pounds more.
A weaker pound makes imported inputs dearer.
The pound rises from 1.15 to 1.25 euro. Keeping the 12 pound price lifts the euro price from 13.80 to 15.00 (8.7 percent); holding the euro price cuts income to 11.04 pounds a jar (8 percent less).
A stronger pound makes exports dearer or less profitable.

Worked reminders

Ethics and profit with numbers

A garment maker buys 40,000 shirts a year from a supplier at Rs 450 each and earns Rs 3,600,000 profit. The supplier asks for Rs 495 so that it can pay fair wages.

  • Rise: 45/450 = 10%.
  • Extra cost: 40,000 × 45 = Rs 1,800,000.
  • Profit falls to Rs 1,800,000, which is a fall of 50%.

Use figures like these to support a judgement: the firm could cover the extra cost with a price rise of Rs 45 per shirt, which is 6% of an average selling price of Rs 750.

Payback on a green investment

A new boiler costs Rs 420,000 and cuts a Rs 2,500,000 energy bill by 12%. The yearly saving is Rs 300,000, so the cost is recovered in 420,000/300,000 = 1.4 years. That supports the case for acting, though an answer should also mention the cash needed at the start.

Case-study skills for this topic

  • Application: use the name of the business, product and place from the stimulus in each sentence.
  • Analysis: build a chain of reasoning, for example new filter, higher cost, lower profit, but fewer fines and better image.
  • Evaluation: weigh both sides, say which matters more in this case and why. Short-term cost against long-term reputation is a common line of judgement.
  • Command words: state and identify need a short answer; explain and analyse need a developed chain; evaluate, justify and recommend need a reasoned decision.

Quick exchange-rate cues

  1. Ask which direction the currency moved.
  2. Decide whether the business sells abroad (exporter), buys abroad (importer) or both.
  3. Say what happens to prices, competitiveness and profitability.
  4. Mention one thing the business can do, such as changing supplier or adjusting prices.

Must-know distinctions

  • External cost or benefit versus private cost or benefit.
  • Tariff (tax) versus quota (limit).
  • Appreciation versus depreciation.
  • Benefit to the MNC versus benefit to the host country.
  • Legal duty (must do) versus ethical choice (ought to do).

Quick self-test

  1. State what an externality is.
  2. A town gains 60 jobs from a new brewery. Is this an external or private benefit?
  3. Give one way a business can contribute to sustainable development.
  4. Name two methods a pressure group could use.
  5. A 25% tariff is placed on an imported item priced at Rs 800. What is the new price?
  6. Why might a government choose a quota rather than a tariff?
  7. Explain repatriation of profits.
  8. A country’s currency depreciates. State the likely effect on its exporters.
  9. A buyer pays 15% more to growers, raising the price from Rs 120 to what per kg?
  10. Give one reason a business might refuse to use a cheaper supplier that employs children.

Answers

  1. A cost or benefit to people who are not part of the business or its customers.
  2. External benefit, because it gains people outside the business.
  3. Any one: renewable energy, recycling, reducing waste, sustainably sourced materials.
  4. Any two: publicity campaigns, petitions, protests, calling for a boycott, lobbying the government.
  5. Rs 1,000 (800 × 1.25).
  6. It sets a firm limit on quantity, which protects local firms by capping imports, though it raises no tax revenue.
  7. Profits earned in a host country are sent back to the MNC’s home country, not reinvested locally.
  8. Its goods become cheaper abroad, so export sales may rise.
  9. Rs 138 (120 × 1.15).
  10. To protect its reputation, avoid boycotts and act ethically.

Where marks are usually lost

  • Giving a cost to the business itself when asked for an external cost.
  • Confusing a tariff with a quota, or calling a quota a tax.
  • Describing what a pressure group wants, not the method it uses.
  • Reversing appreciation and depreciation in an exchange-rate answer.
  • Listing MNC effects without linking them to the host country in the case.
  • Writing a one-sided answer to an “evaluate” or “justify” question.
  • Inventing named laws instead of describing the legal control in general terms.
  • Naming an ethical issue but not giving a business response.

Frequently asked questions

What is the difference between an import tariff and an import quota? An import tariff is a tax on imported goods, which raises their price. An import quota is a limit on the quantity of a good that may be imported.

What is the difference between an external cost and an external benefit? An external cost is borne by third parties, such as smoke harming the health of people nearby. An external benefit is a gain to third parties, such as local jobs created when a new factory attracts shops and cafes.

What is the difference between appreciation and depreciation of a currency? Appreciation means a currency buys more foreign currency, while depreciation means it buys less. Reversing the two is the usual way to lose all the marks on an exchange-rate question.

What is repatriation of profits? Repatriation of profits means a multinational sends profits back to its home country instead of reinvesting them where they were earned.
