HookOasis at £355 — the morning Britain watched supply meet demand
On the morning of 31 August 2024, an estimated ten million people joined online queues for roughly 1.4 million Oasis reunion tickets. Fans who had waited hours watched standing tickets advertised at about £148 reappear at the checkout relabelled 'in demand' — now priced at £355. The fury was instant and national; within a week the Competition and Markets Authority had opened an investigation into how Ticketmaster's pricing had been presented to buyers.
Now strip out the anger and look at the numbers. Ten million buyers were chasing 1.4 million tickets: at £148, quantity demanded exceeded quantity supplied several times over. Something had to ration that shortage, and the only candidates are ever price, queues or luck. Ticketmaster used price — live, in public, in front of everyone — and Britain got a real-time demonstration of what economists call the price mechanism. Whether it was fair is a genuinely open question (and one 1.5 returns to). How it worked is not. Section 1.3 gives you the machinery: what demand and supply actually are, how they determine price, and what prices then do to buyers, sellers and rivals.
ModelDemand — willing AND able, at each price
Demand is the quantity of a good consumers are willing and able to buy at each price in a given period — wanting an Oasis ticket without £355 is desire, not demand. The law of demand says price and quantity demanded move in opposite directions: as price rises, substitutes look relatively better and your income simply stretches less far.
Hold on to the distinction that decides more marks than any other in this section. A change in the good's own price causes a movement along the demand curve — nothing about the curve itself has changed. The curve shifts only when a non-price factor changes: real incomes; tastes, fashion and advertising (when Prime Hydration launched in UK supermarkets at about £2 a bottle, playground hype reportedly pushed resale prices above £10 — demand had shifted right faster than shelves could be stocked); the price of substitutes (a Pepsi price rise shifts demand for Coke right) and complements (dearer printers shift demand for ink left); and population size and structure. In every written answer, name which of the two you mean, because 'the price rise reduced demand' is precisely the sentence examiners are trained to penalise.
ModelSupply — what producers will bring to market at each price
Supply is the quantity producers are willing and able to sell at each price in a period. The law of supply runs upward: higher prices widen margins and make higher-cost production worth undertaking, so more is offered. As with demand, own-price changes move you along the curve; the curve shifts when the conditions of production change — costs of inputs (energy, wages, raw materials), technology, indirect taxes and subsidies, weather and disease, and the number of sellers.
Britain ran the experiment in 2022. The worst avian flu outbreak on record forced the culling of millions of birds, while feed and energy costs had already jumped after the invasion of Ukraine. Egg producers' costs rose while flocks shrank: supply shifted hard to the left. By November 2022 Tesco, Asda and Lidl were rationing boxes per customer, and egg prices rose by roughly a third over the following year. Note what did NOT happen: consumers' incomes, tastes and habits were unchanged. One curve moved, and both the price rise and the empty shelves followed from it — which is exactly the causal discipline a data-response answer needs.
MechanismPrice determination — the only price that can last
Put the curves together and there is exactly one price at which the plans of buyers and sellers are consistent: the equilibrium (market-clearing) price, where quantity demanded equals quantity supplied. At any price below it there is excess demand — a shortage — and frustrated buyers bid the price up. At any price above it there is excess supply — a surplus — and sellers with unsold stock cut the price. Equilibrium is not a moral verdict; it is simply the only price with no built-in pressure to change.
Disequilibrium prices do not just sit there politely. Hold price below equilibrium and the shortage has to be rationed some other way — queues, ballots, and a resale market where the true equilibrium reasserts itself at the tout's price. That is the standing-ticket story in one sentence.
An arena run has capacity fixed at 60,000 tickets, whatever the price. Suppose demand is Qd = 100,000 − 250P. Equilibrium: set 100,000 − 250P = 60,000, so 250P = 40,000 and P = £160; check: 100,000 − 250 × 160 = 60,000. ✔ Now the promoter prints tickets at £120 instead: Qd = 100,000 − 250 × 120 = 70,000 against 60,000 seats — a shortage of 10,000. Prediction: instant sell-out, queues, and resale listings well above £160, because 10,000 willing buyers left empty-handed. One linear equation, and you have explained both the sell-out and the touts — state the formula, substitute, and interpret in a sentence, which is the full method for any calc mark.
MechanismThe price mechanism — rationing, signalling, incentive
Prices are not just amounts you pay; they are the economy's information system, and Edexcel wants the three functions by name. Rationing: when something is scarce, a rising price allocates it to those willing and able to pay — the Oasis surge did in seconds what a decade of queueing culture never could. Signalling: price changes broadcast information without anyone organising it — 2022's egg prices told every producer in the country 'restock, expand' just as surely as a government memo, and told consumers 'economise, substitute'. Incentive: the higher price makes acting on the signal profitable, pulling resources into the market. When UK used-car prices jumped by around 30% in 2021 during the chip shortage, dealers scoured auctions and part-exchanges for stock nobody had wanted a year earlier — no committee required.
The honest caveat, which is where evaluation marks live: the mechanism rations by willingness and ability to pay, so it weights the wants of the rich more heavily than those of the poor. That is not a malfunction — it is how the machine is built — but it is why societies overrule the price mechanism for some goods (NHS treatment, school places) and why the Oasis argument was really an argument about fairness, not about whether the mechanism worked.
CaseUnderstanding the consumer — and never taking your eyes off the competition
Real consumers are messier than the model: they buy from habit, stay loyal to brands past the point of rational comparison, follow crowds, and anchor on familiar reference prices. Firms that understand demand as it actually behaves — rather than as the textbook draws it — make better price and product decisions, which is why they pay so much to see it up close. Tesco's Clubcard, launched in 1995 and now in over 20 million households, exists to observe demand one basket at a time; the discounts are the fee Tesco pays for the data. Market research before launch, loyalty data after it: both are attempts to answer 1.3's core question — how much will people buy, at what price, and what shifts it.
And no firm reads its demand curve alone, because rivals are standing on it. When a competitor cuts price or improves quality, your demand shifts left at every price you might charge. Tesco's Aldi Price Match, launched in 2020, matched hundreds of staple products to the discounter's prices precisely to stop shoppers sampling the substitute — a demand-curve defence, priced off a rival's list rather than Tesco's own costs. That is the final habit this section should leave you with: for any market in an extract, sketch the two curves, then ask who else is selling, because the competition decides how much pricing freedom the demand curve really allows.
VocabularyKey terms the mark scheme pays for
TrapsMisconceptions that cost marks
ExamWhat examiners want
The single biggest mark-loser in 1.3 is shift-versus-movement, so make your sentences do the work: name the curve, the direction, and the cause — 'avian flu culled flocks and raised feed costs, shifting supply left; at the old price there was excess demand, so price rose and quantity fell'. Every link earns; every skipped link is an analysis mark forgone. When you conclude, state BOTH the new price and the new quantity — half the equilibrium is half the answer.
Calculation questions want the ritual: formula, substitution, answer with unit, one-line interpretation. On price-mechanism questions, name the function you can see operating — rationing, signalling, incentive — and evidence it from the extract rather than defining all three in the abstract. And keep an evaluation card ready: how fast supply can actually respond (fixed arena capacity versus manufacturable goods), and who the price system leaves out — willingness to pay is not the same as need, which is the bridge Edexcel builds from this section straight into market failure in 1.5.
