The Private Sector and the Public Sector
Before you can judge what an organisation should do, you need to know who owns it. Ownership decides where the money comes from, who it answers to and what counts as success. A hospital and a hotel can be the same size and still be playing completely different games.
📘 What you need to know
Public sector organisations are owned and run by the government and funded mainly by taxation.
Private sector firms are owned by individuals and other firms, funded by owner’s capital, borrowing and retained profit.
The public sector usually aims to provide a service; the private sector usually aims to make a profit.
Privatisation is selling a state-owned organisation to private owners. Nationalisation is the reverse.
Some firms are partly privatised — government and private shareholders own it together.
Governments keep hold of things that are strategically important, essential or merit goods.
Two owners, two purposes
The right-hand column is under constant pressure to cut costs, because profit depends on it. The left-hand column is under pressure to keep the service running, even where it loses money.
Why efficiency is usually higher in the private sector
This is a chain worth learning, because it turns up in almost every question on this topic.
Private firms need profit to survive, so every cost is under scrutiny.
Owners can lose their money, so weak managers get replaced.
Competitors are trying to take the customers, so standing still is dangerous.
Therefore productivity tends to be higher and costs tend to be lower.
The public sector faces a different set of pressures. A rural bus route that loses money every year may still be worth running, because the point is access, not profit. Judging it by profit would give the wrong answer.
Be careful with the word “efficient” in an essay. Private firms are usually more cost-efficient. That is not the same as being better for society. A private water company that cuts maintenance to boost profit is efficient right up to the moment the pipes burst.
Why governments hold on to some organisations
Reason
What it means
Typical examples
Strategically important
The country could not function or defend itself without it
Defence, courts, border control
Essential services
Everyone needs it and nobody can opt out
Water, electricity supply, sewerage
Merit goods
Useful to society but private firms would supply too little
Education, public health, libraries
Natural monopoly
It only makes sense to have one network
Rail track, national grid
Privatisation and nationalisation
Ownership is not fixed. Organisations move between the sectors, and governments change their minds.
Partial privatisation sits in the middle. Singapore Airlines, for example, has long had a majority government stake alongside private shareholders, so the government still influences decisions and still takes a share of the profit.
The wider trend: over recent decades most governments have moved away from running things centrally, encouraging private business instead. Cuba now allows small private firms. Venezuela moved the other way and increased state involvement. Both are useful, easy-to-remember examples.
EXAM-STYLE
Explain two reasons a government might privatise a state-owned railway. [4]
Reason 1: raise money
Selling the railway brings in a large one-off payment.
The government can spend that on schools or hospitals instead of subsidising trains every year.Reason 2: efficiency
Private owners face competition and the risk of loss, so they have a reason to cut waste.
Costs per journey may fall, which the government cannot easily force to happen while it owns the network itself.One financial reason, one operational reason
EXAM-STYLE
Evaluate that decision from the passengers’ point of view. [6]
In favour
Investment may improve trains and punctuality, because the owner wants more paying passengers.
Againstprofit motive + quiet rural line = route closed
Fares may also rise if there is no competing operator.
It depends on
How tightly the government regulates fares and forces the operator to keep unprofitable routes open.
Good for busy routes, risky for the quiet onesan “it depends on” line is the fastest way into the top band
💡 Exam tip
Start with ownership and funding. Every other difference follows from those two facts.
Public sector does not mean public limited company. This wording trap catches students every year.
Use “provide a service” not “not make profit”. Public sector bodies do care about money, they just do not exist for it.
Name a stakeholder when you evaluate privatisation — taxpayers, workers, customers and government all gain or lose differently.
Merit goods is a strong technical term. Use it once, correctly, and it lifts the answer.
If the case study mentions a subsidy, that is a signal the organisation cannot cover its costs from customers alone.
⚠ Common mix-up
Public sector versus public limited company. A plc is private sector. “Public” there just means the shares are traded publicly.
Private sector is not only small firms. Some of the biggest firms on earth are private sector.
Public sector organisations still need income. They charge fees, sell services and worry about budgets.
Privatisation is not automatically good or bad. It depends on regulation and on which stakeholder you are.
Partly privatised firms exist. Do not force every organisation into one column.
Efficient is not the same as fair. Cutting a loss-making rural service is efficient and unfair at the same time.
