HookThames Water — one network, five competing claims
Thames Water was privatised in 1989 carrying no debt at all. Thirty-five years later it owes roughly £19 billion, serves about 16 million customers who cannot switch to a rival, and spent 2023 and 2024 lurching between rescue plans while raw sewage spilled into the rivers it is paid to protect. Along the way, its owners did rather well: under Macquarie's ownership between 2006 and 2017, dividends of roughly £2.7 billion flowed out of the company while the debt pile grew. In December 2024 the regulator Ofwat approved bill rises of about 35% by 2030 — so customers will pay more for a network they already feel has failed them.
One network of pipes; five competing claims on it. Shareholders wanted dividends. Customers want low bills and clean rivers. Employees want secure jobs and rising pay. Ofwat wants billions invested in leaking Victorian mains. And the environment — represented by nobody at the boardroom table — needed the sewage discharges to stop. There is not enough money in the system to satisfy everyone, which means someone must choose, and every choice creates a loser. That is the whole of 1.1 in a single company: scarcity forces choices, every choice carries an opportunity cost, and different economic agents want incompatible things.
ModelThe economic problem — infinite wants, finite everything
Human wants are unlimited; the resources available to satisfy them — land, labour, capital, enterprise — are not. That mismatch is scarcity, and it is the founding problem of economics. Scarcity forces choice, and every choice has an opportunity cost: the value of the next best alternative forgone. Not the money spent — the alternative given up.
Every economic agent faces it. A student with £20 chooses between a night out and a month of Spotify. A firm with a fixed capital budget chooses between a new production line and a marketing push — Thames Water choosing dividends over pipe renewal is exactly this decision, made repeatedly for three decades. And government faces it on the grandest scale: every extra pound for the NHS is a pound unavailable for schools, defence or debt interest. Economists judge decisions by opportunity cost rather than money cost, because the price tag measures what you paid for the thing you chose, while opportunity cost measures the value of the thing you sacrificed to get it — and only the second tells you whether the choice was wise.
October 2023: the government cancelled HS2's Birmingham–Manchester leg and redirected roughly £36 billion towards road, bus and local rail schemes branded Network North. Run it as an exam answer. Knowledge: opportunity cost is the value of the next best alternative forgone. Application: the opportunity cost of continuing HS2 was every Network North project that the £36 billion could otherwise fund. Analysis: as construction costs rose, the sacrificed alternatives grew more valuable relative to the line's benefits, so the rational choice flipped — cancelling was not an admission the railway had no value, only that something else now had more. Evaluation: opportunity cost depends on whose ledger you read — for Manchester firms that had invested expecting the line, the cancellation imposed costs no Treasury spreadsheet recorded. Four sentences, four skills: a complete K-A-A-E chain.
ModelBusiness objectives — profit is one option, not a law of nature
The spec expects you to know the menu of objectives and, crucially, when each one dominates. Profit maximisation — making the gap between total revenue and total cost as wide as possible — is the default assumption, because profit rewards shareholders and funds investment. But real firms flex. Survival takes over in crises: in the spring 2020 lockdowns, high-street chains stopped asking how much they could make and started asking how long their cash would last. Growth and market share dominate young markets: Amazon ran razor-thin profits for the best part of two decades because scale today buys pricing power tomorrow, and Deliveroo burned losses for years chasing the same logic. Ethical and social objectives are real too: Timpson deliberately recruits ex-offenders — over a tenth of its workforce — accepting recruitment costs a pure profit-maximiser would refuse, because its owners believe the social return is worth it. And many owners satisfice: they earn enough profit to live comfortably and stop pushing, trading the last pound of profit for an easier life. In every data question, ask which objective the evidence actually supports — not which one the textbook lists first.
MechanismStakeholders — everyone with a claim on the firm
A stakeholder is any individual or group affected by a firm's decisions. Internally: owners and shareholders (dividends and a rising share price), managers (salaries, status, growing empires), employees (pay, security, conditions). Externally: customers (low prices, quality, service), suppliers (steady orders and prompt payment), lenders (repayment), government (tax revenue, jobs, compliance with the law) and the local community and environment (clean air, employment, quiet nights).
Conflict is built in, because the same pound cannot satisfy two claims. Higher wages squeeze profit. Bigger dividends starve investment — the Thames Water story in miniature. Lower prices delight customers and thin margins. Automation cuts costs and jobs simultaneously. Fifty years ago Milton Friedman argued that the only social responsibility of business is to increase its profits within the rules; the modern stakeholder view answers that firms which ignore workers, communities and the environment eventually pay for it in recruitment, regulation and reputation. Edexcel B does not ask you to pick a side — it asks you to show both and judge by context. The exam skill is never just listing stakeholders: it is naming the pair in conflict and the mechanism that connects them, then judging who wins in the short run and who wins in the long run.
CaseP&O Ferries — every conflict in one afternoon
On 17 March 2022, P&O Ferries sacked around 800 seafarers over a pre-recorded video message, with security escorts waiting at the gangways, and replaced them with agency crews on far lower rates — lawful, mostly, because its ships sail under foreign flags in international waters. Its chief executive then told MPs the firm had knowingly skipped the legally required consultation period and would do it again, because consultation would have sunk the turnaround. That is an opportunity-cost calculation said out loud: the fine and the fury were judged cheaper than the delay.
Score the stakeholders. Winners: the parent company DP World, which stemmed losses on the routes, and arguably future passengers, who kept a ferry service that might otherwise have folded. Losers: the sacked crews, the unions, a government embarrassed by the legal loophole, and the brand itself — bookings and reputation took years of damage, a long-run cost set against a short-run saving. When a 1.1 extract hands you a firm, run this exact scan: each stakeholder, their objective, the mechanism of the conflict, and the short-run versus long-run winners. That scan is the application mark, and most of the analysis mark, done.

TrapsMisconceptions that cost marks
ExamWhat examiners want
Definitions are free marks if you are precise: opportunity cost is the value of the next best alternative forgone — examiners withhold the mark when 'next best' is missing. Learn the business objectives as a menu and always justify which one fits the firm in the data, quoting the evidence that points to it.
Stakeholder questions are where 1.1 earns its 8- and 12-markers, and the levels descriptors follow K-A-A-E: define the stakeholders (knowledge), anchor them in the extract's firm (application), trace the mechanism of conflict — the same pound cannot pay a dividend and renew a pipe (analysis) — then weigh it (evaluation): who wins in the short run versus the long run, does the answer depend on the firm's objective, could both sides gain over time? A one-sided answer caps at the middle level however elegantly it is written. And never invent stakeholders: use the ones the extract actually names, because application marks attach to the case on the page, not to your memorised list.
