Component 3: PEST factors – Economic explained
Growth, unemployment, inflation, interest rates, exchange rates and consumer confidence all reach the firm as either a change in demand or a change in cost, and the size of the effect can be measured.
Read the full explanation
Income elasticity of demand, the percentage change in quantity demanded divided by the percentage change in income, tells a manager which way a downturn will push sales: a positive figure above one marks a luxury such as a restaurant meal, which falls hard, while a negative figure marks an inferior good such as own label pasta, which rises. Exchange rates work on the cost side, since a stronger pound makes imported components cheaper and exports dearer abroad. None of this is controllable, so the real question is response: flexible capacity, hedged currency, a wider range, or a move on Porter's generic strategies towards cost leadership as incomes tighten.
Explain what is meant by economic growth and the business cycle and their measurement (GDP)
Growth is the rise in real gross domestic product, the total value of output produced in the economy over a period, published quarterly by the Office for National Statistics and stated in real terms so that price rises are stripped out; dividing by population gives output per head, which is the better guide to whether customers actually feel richer. Around the trend the economy moves through boom, slowdown, recession, taken in the United Kingdom as two consecutive quarters of falling real output, and recovery. Managers read the position in that cycle to time decisions that take months to reverse: taking on a lease, recruiting permanent staff, building inventory or starting a capital project. The difficulty is that the data is backward looking and heavily revised, so a firm reacting to a confirmed recession is already late.
Explain what is meant by inflation including its measurement and causes
A sustained rise in the general price level means money buys less each year, and in the United Kingdom it is tracked by the Consumer Prices Index, a weighted basket of several hundred goods and services repriced every month by the Office for National Statistics, with the Retail Prices Index differing mainly by including some housing costs. The causes split two ways. Demand pull comes from spending running ahead of what the economy can supply; cost push comes from rising input prices such as energy, imported components or wages. The distinction matters because it changes the effect on a firm. Cost push squeezes margins directly and forces a choice between absorbing the increase and raising price, while demand pull at least arrives alongside strong sales. Note also that a falling rate is still rising prices, which is not deflation.
Explain what is meant by interest rates
The price of borrowing and the reward for saving, quoted as a percentage a year, anchored for the whole economy by the Bank of England base rate and then marked up by lenders into the figure a firm actually pays. Managers use the number twice over. It sets the cost of servicing debt, so a highly geared firm on variable rate loans feels a rise in its next set of accounts, and it sets the discount rate in an investment appraisal, so a rise shrinks discounted inflows and can push a project below its hurdle. It also works through customers, because mortgage holders with smaller disposable incomes delay big purchases. The trade off is that cheap money tempts firms to borrow, and the interest burden that follows is fixed whatever happens to sales.
Explain what is meant by exchange rates
The value of one currency expressed in another, set in a floating system by supply of and demand for the currency. For a firm it fixes two prices at once: what an export costs the overseas buyer, and what an imported component costs at home. The shorthand worth remembering is that a strong pound makes imports cheap and exports dear, and a weak pound reverses it. Managers use the rate to decide whether to reprice abroad, absorb the movement in the margin, hedge with a forward contract or move sourcing. The trade off is that no movement is wholly good, because an exporter that builds its product from imported materials gains on inputs while losing on revenue, and the net effect depends on the share of costs bought in foreign currency and on whether overseas demand is price elastic.
Explain what is meant by unemployment
People willing and able to work at going wage rates who cannot find a job, measured in the United Kingdom by the claimant count and by the Labour Force Survey and expressed as a percentage of the labour force. For an exam answer the types matter more than the headline number: cyclical joblessness rises in a recession and drains demand, structural joblessness follows a permanent shift in what the economy makes, frictional joblessness is short movement between jobs, and seasonal joblessness follows the calendar. The effect on a business cuts both ways, because a slack labour market widens the applicant pool, eases wage pressure and lowers labour turnover, while the same slack economy thins the queue of paying customers.
Evaluate the impact of the business cycle, inflation, interest rates, exchange rates and unemployment on businesses and their stakeholders
This is the synoptic economic question and the marks live in judgement, not in listing. A strong answer picks the one or two variables that actually bite on the firm in front of it, traces a chain from the change to a number the business cares about such as operating profit, cash flow or capacity utilisation, then weighs winners against losers group by group. Shareholders, employees, suppliers, customers, lenders and the local community rarely move together, so a downturn that protects a discounter's sales can still frighten its suppliers into demanding faster payment. The criteria that earn the top band are the size of the change, how long it is expected to last, whether it had been forecast, and how much financial slack the firm holds in cash and unused borrowing capacity.

Component 3: PEST factors – Economic exam tips
Marking Points
- Credit separating demand side effects, such as incomes, confidence and unemployment, from cost side effects, such as interest rates, wages, commodity prices and the exchange rate.
- Credit using income elasticity of demand, the percentage change in quantity demanded divided by the percentage change in income, and interpreting both the sign and the size for the named product.
- Credit the exchange rate mechanism, that a stronger pound lowers import costs and raises the foreign price of exports, applied to a firm that genuinely imports or exports.
- Credit a response rather than only an effect, for example flexible contracts, hedging, repositioning the range or moving towards cost leadership.
- Credit recognising what the generic strategies model is blind to, since it says nothing about how quickly a firm can switch position or whether it can fund the switch.
- Credit defining growth as an increase in real gross domestic product, with real meaning adjusted for inflation, and knowing it is measured and published quarterly.
- Credit naming the stages of the cycle, boom, slowdown, recession and recovery, and stating the technical definition of recession as two consecutive quarters of falling real output.
- Credit the distinction between total output and output per head, and why the second matters more for consumer spending power.
- Credit applying the stage of the cycle to a decision with a long lead time at the named firm, such as recruitment, leasing, stock building or capital investment.
- Credit evaluation of the data itself, that figures are lagged and revised, so the cycle is identified with certainty only after the event.
- Credit a precise definition, a sustained rise in the general price level over time, rather than the loose idea that prices go up.
- Credit the measurement detail: a weighted basket of goods and services, priced monthly, reported as an annual percentage change, with the Consumer Prices Index as the official target measure.
- Credit distinguishing demand pull from cost push and identifying which one the extract actually describes.
- Credit tracing inflation to the business: input costs, contribution per unit, pricing decisions, wage claims and the likelihood of a rise in Bank Rate in response.
- Credit the distinction between a falling rate of inflation and deflation, and the point that inflation erodes the real value of existing debt.
- Define the rate as the cost of borrowing and the return on saving expressed as a percentage a year, and separate the Bank of England base rate from the higher rate the named firm pays on its overdraft or term loan.
- Work the cost side: a rise lifts interest payments on variable rate debt and squeezes operating profit, and it hurts most where gearing, non current liabilities divided by capital employed times one hundred, is already high.
- Work the demand side: dearer credit cuts household disposable income, so credit funded purchases such as cars, kitchens and new homes fall long before weekly groceries do.
- Connect the rate to investment appraisal by naming it as the discount rate used in net present value, so a rise reduces the present value of future inflows and can turn a positive net present value negative.
- Define the rate as the value of one currency in terms of another and state the direction precisely, for example the pound appreciating from one euro fifteen to one euro twenty five.
- Apply the rule for a strong pound, imports cheap and exports dear, then reverse it for a weak pound, and say which line of the income statement each effect lands on.
- Bring in price elasticity of demand, since an appreciation only damages export revenue badly where overseas demand is price elastic, so a differentiated luxury brand loses less volume than a commodity exporter.
- Quantify where the data allows, converting a price at the old rate and at the new rate and commenting on the volume lost or the margin sacrificed to hold the foreign price steady.
- Distinguish the types by name, cyclical, structural, frictional and seasonal, and say which one the case study is describing.
- Explain the recruitment effect: more applicants per vacancy, weaker wage demands and lower labour turnover, which is leavers in a year divided by average number employed times one hundred, so recruitment and training costs fall.
- Explain the demand effect: lost household income cuts sales of normal and luxury goods, while inferior goods, value ranges and discounters can gain.
- Add the regional and skills dimension, because a firm needing welders or software engineers gains nothing from unemployment among retail staff in another region.
- Build a chain of reasoning rather than a list, for example downturn, falling real incomes, customers trading down, lower volume, weaker capacity utilisation, which is actual output divided by maximum possible output times one hundred, and a higher fixed cost per unit.
- Take at least two stakeholder groups in opposite directions and support each with evidence from the case study, because balanced impact is where the higher marks sit.
- Justify the judgement against stated criteria such as magnitude, duration, whether the change was anticipated, the firm's gearing and its cash position.
- Show the variables interacting, since inflation invites a rise in interest rates, which tends to strengthen the currency and cool demand, so they cannot be treated as independent.
Examiner Tips
- 💡Extracts nearly always give at least one economic figure, so quote it and calculate with it rather than describing the trend in words.
- 💡Decide early whether the firm is more exposed on demand or on cost, because that choice organises the whole answer.
- 💡Evaluation marks come from how long the effect lasts and whether this firm has the finance or flexibility to ride it out.
- 💡If the extract gives quarterly percentages, state plainly whether the economy is growing, slowing or contracting before analysing anything.
- 💡Link the stage of the cycle to the product: cyclical goods such as new cars and fitted kitchens swing far harder than food or repairs.
- 💡Definitions score quickly here, so spend the remaining marks on what the position in the cycle means for this business next year.
- 💡Whenever an inflation figure appears, ask whether the firm can pass it on, which returns you to price elasticity of demand and brand strength.
- 💡Real terms comparisons are common, so be ready to set a wage rise or a sales increase against the inflation rate to say whether it is a real gain.
- 💡Use the cause named in the extract to structure the analysis, because demand pull and cost push lead to different recommendations.
- 💡The rate is always attached to a named firm in the case study, so spend a sentence on that firm's borrowing or its customers' use of credit before judging anything.
- 💡Interest rates often arrive hidden inside an investment appraisal question as the discount rate or the cost of finance, so calculate first and comment second.
- 💡For an evaluate answer, argue duration and contract type: a firm on fixed rate borrowing may feel nothing at all until refinancing.
- 💡The case study normally gives the share of sales exported and the share of components imported, and those two figures are the intended route into the evaluation.
- 💡A short calculation is often embedded, so convert a price both ways and comment on the gap rather than describing the movement in words alone.
- 💡Evaluate by weighing the size and expected permanence of the movement against the firm's ability to hedge, reprice or source at home.
- 💡Examiners expect both sides, so plan one paragraph on the firm's labour market and one on its customers before reaching a judgement.
- 💡If the case study names a value brand or an inferior good, argue that rising unemployment may lift its sales, which is a ready made evaluation point.
- 💡Use the region and sector given in the case study, because a general comment about the national economy scores little on an applied paper.
- 💡These carry the largest mark tariff on the paper, so budget time for a conclusion that answers the question set rather than summarising the body.
- 💡Plan in two lines, naming the two strongest impacts and the two most affected stakeholder groups, before you start writing.
- 💡Where numerical data is supplied, quote a figure from it inside the judgement, because an evaluation anchored in the case study's own numbers reads far stronger than assertion.
Common Mistakes
- Treating a recession as bad for every business, when discounters, repair services and own label producers frequently gain share.
- Getting the exchange rate the wrong way round and claiming a stronger pound helps exporters.
- Quoting an elasticity with no sign or size, so the answer cannot say whether the good is a luxury, a necessity or an inferior good.
- Confusing nominal and real growth, so a rise caused entirely by higher prices is reported as more output.
- Saying output has fallen when the extract shows a fall in the growth rate, which still means the economy is expanding, only more slowly.
- Describing the cycle as a neat, predictable wave and assuming a firm can time its expansion precisely against it.
- Saying that because inflation has fallen, prices have fallen, which confuses the rate of change with the level.
- Describing only the effect on customers and never reaching the firm's own costs, margins or supplier contracts.
- Naming a cause with no evidence, for example asserting demand pull when the extract clearly describes an energy price shock.
- Assuming every business suffers from a rise, when a debt free firm sitting on cash deposits actually earns more interest and gains.
- Confusing the interest rate with the rate of inflation, or asserting that a rise is bad news without weighing it against the firm's gearing and its customers' spending patterns.
- Saying costs rise without saying which costs, when interest is a finance cost that leaves gross profit untouched and bites on profit after interest.
- Reversing the direction of the effect, most often by claiming a strong pound helps exporters because the pound is worth more.
- Forgetting that most exporters are also importers, so an appreciation cuts input costs at the same moment it squeezes export revenue.
- Ignoring hedging and forward contracts, which can mean a firm feels a movement months later or not at all.
- Treating unemployment purely as a social problem and never converting it into a business consequence such as cheaper labour or weaker sales.
- Assuming any unemployed person can fill any vacancy, which ignores structural unemployment and skills mismatch.
- Confusing the unemployment rate with the raw number out of work, or counting the economically inactive such as students, carers and the retired as unemployed.
- Writing a general economics essay with no reference to the named business, which caps the answer on application and blocks the top band.
- Assuming every economic change harms every firm, and so missing counter cyclical businesses such as repair services, discount retailers and debt advice firms.
- Listing stakeholders without saying how each is affected differently, which reads as a definition list rather than an evaluation.
- Treating a fall in the rate of inflation as falling prices, when prices are still rising, only more slowly.
