Production, Costs/Revenue/Profit and the Labour Market

Same two players, swapped seats

This topic looks like two topics: how firms make things and what they earn, then how wages are set and what lands in a payslip. It is really one picture. A firm and a household meet in two different markets, and they swap seats between them. ⭐ In the market for goods, the firm SELLS and the household BUYS. A bakery sells bread; a family buys it. ⭐ In the labour market, the household SELLS and the firm BUYS. The same family sells its time and skills as work; the bakery buys that work and pays a wage for it. ⭐⭐ AND EACH SIDE READS THE SAME KIND OF STATEMENT: WHAT COMES IN, WHAT GOES OUT, AND WHAT IS LEFT. For the firm, money comes in as revenue from sales and goes out as costs. What is left is profit, or, if costs are bigger, a loss. For the worker, money comes in as pay for the work and some goes out before it ever arrives, as tax and other deductions. What is left is net pay. Hold that picture and every calculation in this module is the same question asked from a different seat: what is left once everything that goes out has gone?

Words for what a producer counts

Six terms the specification asks you to calculate and explain. Notice that each total has an average partner: the same figure shared across every unit made or sold.

Who counts as a producer here

A town has a self-employed plumber, a supermarket owned by shareholders, and a swimming pool run by the local council. Which of them are producers in the economic sense?

• All three: an individual, a firm and the government can each produce goods or services
• Only the supermarket, because only a company with shareholders counts as a producer
• The plumber and the supermarket, but not the council, because government only spends and never produces
• Only the supermarket, because the others provide services rather than goods

Name each figure on the cafe accounts

One bike workshop, three different weeks

A bike repair workshop pays 300 pounds a week for its unit and tools whatever happens, plus 10 pounds in parts for each repair. It charges 25 pounds a repair. A busy week: 40 repairs. Revenue comes in at 40 times 25, which is 1000 pounds. Costs go out as 300 plus 40 lots of 10, which is 700 pounds. What is left is 300 pounds of profit. Each repair brought in 25 pounds (the average revenue) and cost 700 shared across 40, which is 17.50 pounds (the average cost). A quieter week: 20 repairs. Revenue is 500 pounds. Costs are 300 plus 200, which is also 500 pounds. Nothing is left either way: the workshop breaks even. A slow week: 15 repairs. Revenue is 375 pounds. Costs are 300 plus 150, which is 450 pounds. Costs are bigger, so the result is a loss of 75 pounds. ⭐ Notice what moved the average cost. The 300 pounds of rent is the same every week, so the more repairs it is shared across, the cheaper each repair becomes to do. That is the seed of economies of scale, later in this module. ⭐⭐ And notice the order of work every time: money in, money out, what is left.

Count the stall profit

A market stall sells 120 loaves in a week at 3 pounds each. Its pitch costs 90 pounds for the week, and the ingredients for each loaf cost 1 pound. What profit does the stall make that week, in pounds?

What a cost rise does next

The price of flour rises sharply, and the stall cannot raise the price of its loaves without losing customers. Select the TWO statements that are likely to follow.

• The profit on each loaf falls, because more goes out for every loaf while the same comes in
• Some bakers may offer fewer loaves, or stop baking altogether if they start making a loss
• Profit rises, because a higher cost always pushes up the revenue the stall receives
• Average revenue falls, because average revenue is the cost of making each loaf

Two ways to make each unit cheaper

The specification asks why production and productivity matter, and what economies of scale are. They are two separate routes to a lower average cost. ⭐ Productivity is about the workers: more output from the same hours of work. Better training, better equipment or better organisation means each hour produces more, so the cost of each unit falls even if the firm stays the same size. ⭐ Economies of scale are about size: average cost falls because the firm grows. A big cost that does not change much with output, such as an expensive machine, a building or an advert, is shared across far more units. A larger firm can also buy materials in bulk at a lower price for each one. ⚠️ Keep them apart in an answer. A small firm can raise its productivity without growing; a firm can grow and gain economies of scale without any worker becoming more skilled. ⭐⭐ Why the whole economy cares: production is how a country turns its scarce resources into the goods and services people use, and higher productivity means more of them from the same resources. That is how living standards rise, and it helps firms compete on price with producers abroad.

Tap the economies of scale

Four firms report a change. Tap the TWO that describe economies of scale, where the cost of each unit falls BECAUSE the firm has grown.

• A chain of forty shops pays less per bag of flour than a single corner shop, because it orders by the lorryload
• A printer doubles its output, so the cost of its one expensive press is shared across twice as many books
• After a training course, the same team of joiners makes more chairs in each hour
• A cafe raises the price of coffee to cover a rise in its rent

Selling bread, buying a baker

The same bakery stands in two markets. Read across each row: the roles are the same kinds of thing, but buyer and seller have changed places.

Order how a shortage of workers lifts a wage

A town has too few qualified electricians for all the work on offer. Put these steps in the order in which the labour market responds.

• Employers want more electricians than there are qualified people available
• Jobs go unfilled and work is turned away
• Employers offer higher wages to attract the electricians there are
• Better pay draws more people into training as electricians
• As more qualify, the gap closes and the wage stops rising

Which side of the labour market moved

Three changes hit three different jobs. For each, decide which side of the labour market has moved and what that does to the wage.

• A new hospital opens in a town and needs many more nurses than before.
• A job needs seven years of training, and few people are willing to do it.
• Self-service tills now do much of the work that checkout staff used to do.

What happens between earning and receiving

The wage agreed in the labour market is not what arrives in a bank account. A payslip shows two figures, and the specification asks for both. ⭐ Gross pay is the full amount earned before anything is taken off. ⭐ Net pay is what is left after the deductions, and it is what the worker actually receives. The specification names three deductions: Income tax, paid to the government on earnings above a tax-free amount. National Insurance, also paid to the government, which helps pay for things such as the state pension and some benefits. Pension contributions, money set aside from pay into a pension for the worker to draw in retirement. ⚠️ The first two go to the government; the pension contribution still belongs to the worker, just later. All three come off before the money reaches the account, which is why net pay is always smaller than gross pay. ⭐⭐ It is the firm statement again, read from the other seat: money in, money out, what is left.

What actually arrives

Priya earns 1800 pounds in a month before deductions. From this, 140 pounds goes in income tax, 90 pounds in National Insurance and 70 pounds into her workplace pension. How much is paid into her bank account that month, in pounds?

Complete the turbine engineer story

Several wind farms are built off the coast at once, and each needs engineers to keep its turbines running, so the _____ for turbine engineers rises. The job needs years of specialist training, so the _____ of qualified engineers stays small. Wind farm owners compete for the engineers there are, and the _____ offered rises. On her first payslip, one new engineer sees a large _____ figure, but a smaller amount actually reaches her account.

Build the two-seat sentence

One sentence ties this module together. Assemble it.

Advise the growing furniture workshop

A small furniture workshop moves to a bigger unit, buys a second cutting machine and wants to hire two more skilled joiners. Explain how growing could change its costs, revenue and profit, and why the wage it must offer the joiners depends on the labour market.

• Average cost as output grows, using economies of scale
• Revenue and profit, with one cost that rises
• What sets the joiner wage, using supply and demand
• One reason joiners might be scarce or plentiful
