GDP, inflation, employment and unemployment
GDP (gross domestic product) is the value of all final goods and services produced inside a country in one year. Real GDP removes the effect of price rises. GDP per person = GDP ÷ population. A growing GDP usually means more jobs and income, but it does not show how fairly income is shared.
Inflation is a general rise in prices over time. Inflation rate = (new price level − old price level) ÷ old price level × 100%. With inflation, money buys less: purchasing power falls. A little inflation is normal; high inflation hurts savers and people with fixed incomes.
Unemployment: a person is unemployed if they are without work, available for work and looking for it. Unemployment rate = unemployed ÷ labour force × 100%, where labour force = employed + unemployed. People who are not looking (students, retired) are outside the labour force. The state tries to keep inflation low and jobs high, using the budget and (through its central bank) interest rates.
State and local budgets, deficit and public debt
A budget is a plan of income and spending. The state (central) budget collects taxes such as income tax, VAT and company tax, and pays for defence, health, education, pensions and roads. A local budget (town or region) gets a share of taxes, local fees and grants from the centre and pays for local schools, transport, waste and local services.
Budget balance = revenue − spending. If spending is more, there is a deficit; if revenue is more, a surplus. A deficit is paid for by borrowing (selling bonds). The total of all past deficits, less surpluses, is the public debt.
Debt is not always bad: borrowing for roads or schools can raise future income. But a large debt means large interest payments every year, which crowd out other spending. A common guide is debt as a percentage of GDP.
Consumer rights and making a complaint
A consumer buys goods or services for personal use. Since sellers know more than buyers, the state protects consumers by law. Typical rights: safety (products must not harm), information (true labels, clear price and terms), choice (fair competition), fair contracts, and redress (a remedy when something goes wrong). In many countries you can return faulty goods for repair, replacement or refund.
How to complain: 1) keep the receipt and photos; 2) contact the seller in writing, say what is wrong and what you want (repair, replacement, refund); 3) set a reasonable date; 4) if there is no answer, go to a consumer advice body or ombudsman; 5) as a last step, use mediation or the court. Be polite and specific.
Economic patriotism
Economic patriotism means giving preference to a country's own products, firms and workers: buying local, and sometimes protecting key firms from foreign takeover. Supporters say it keeps jobs and money in the country and builds security in key sectors such as food and energy. Critics say it can make goods dearer, reduce choice, and lead to other countries doing the same, which harms trade for all.
A good consumer decision looks at price, quality and the wider effect on local jobs and the environment.
Try it: a mini household budget
Write your family's monthly income and spending on paper. Is there a surplus or a deficit? If there is a deficit, how would the family cover it? Now try the same with the tax and spending sliders in step 5 of the 3D.
Key formulas and definitions
- GDP per person = GDP ÷ population
- Inflation rate (%) = (new price level − old price level) ÷ old price level × 100
- Labour force = employed + unemployed
- Unemployment rate (%) = unemployed ÷ labour force × 100
- Budget balance = revenue − spending (negative = deficit)
- Debt ratio (%) = public debt ÷ GDP × 100
Worked examples
1. A country has GDP 600 and 20 people (in millions). Find GDP per person.
600 ÷ 20 = 30 per person.
2. A basket costs 200 last year and 210 this year. Find the inflation rate.
(210 − 200) ÷ 200 × 100 = 5%.
3. There are 90 employed and 10 unemployed. Find the labour force and the unemployment rate.
Labour force = 90 + 10 = 100. Rate = 10 ÷ 100 × 100 = 10%.
4. A state collects 400 in tax and spends 450. Find the balance. If debt was 1000 before, what is the debt now?
Balance = 400 − 450 = −50, a deficit of 50. Debt = 1000 + 50 = 1050.
5. Public debt 1050 and GDP 1500. Find the debt ratio.
1050 ÷ 1500 × 100 = 70%.
6. A phone you bought a week ago stops working. List the steps to complain.
Keep the receipt and take photos; write to the seller saying what is wrong and asking for repair, replacement or refund; set a date; if no answer, go to a consumer advice body or ombudsman; as a last step use mediation or court.
Common mistakes
- Calling a price rise of one item inflation. Inflation is a general rise in prices.
- Counting students or retired people as unemployed. They are outside the labour force if not looking for work.
- Mixing up deficit and debt. Deficit is one year's gap; debt is the total of gaps over time.
- Thinking that higher GDP means everyone is better off. GDP does not show how income is shared.
