Measure growth, read the cycle and judge its effects
Economic growth is an increase in an economy's real output over time. It is measured by growth in real gross domestic product (GDP), the value of final goods and services produced within the economy.
| Stage | Real GDP / growth | Inflation pressure | Unemployment |
|---|---|---|---|
| boom | output is high and may grow rapidly | usually rises as demand and capacity pressure build | usually low |
| downturn | growth slows and output may begin to fall | usually eases | usually rises |
| recession | real GDP falls and activity is weak | usually low or falling, though supply shocks can differ | high or rising |
| recovery | real GDP begins rising again | may start to rise | usually falls as firms hire |
| Possible benefit of growth | Possible cost or limit |
|---|---|
| firms hire more workers and unemployment falls | rapid demand growth can cause inflation |
| higher incomes can improve living standards and reduce poverty | gains may be unequally distributed |
| investment can expand productive potential | extra production can create air, water, noise and visual pollution |
| higher profits, spending and tax revenue can support further activity | finite resources may be depleted and the economy may overheat |
GDP enables comparisons over time and between countries, but use real GDP to remove inflation and real GDP per person when population differs. GDP still misses distribution, much informal activity, unpaid output, environmental costs and other aspects of wellbeing.
A rise in nominal GDP can reflect higher prices rather than more output. Growth in total real GDP does not guarantee that real GDP per person or every household's living standard rose.
Trace inflation from CPI causes to economy-wide effects
Inflation is a sustained rise in the general price level; deflation is a sustained fall. Low and stable inflation makes planning easier than high, volatile inflation or deflation.
A consumer price index (CPI) tracks the cost of a weighted representative basket of household goods and services. Weights reflect how much households typically spend on each category.
inflation rate=previous CPIcurrent CPI−previous CPI×100
| Type | Causal chain |
|---|---|
| demand-pull | aggregate demand grows faster than productive capacity → firms raise prices |
| cost-push | wages, energy, raw materials, taxes or import costs rise → unit costs rise → firms raise prices or reduce output |
| Channel | Likely effect of high or unstable inflation |
|---|---|
| prices and wages | purchasing power falls when wages lag; wage demands may rise |
| exports | domestic goods become less price competitive if inflation exceeds trading partners' |
| employment | demand-pull pressure can initially support jobs; severe cost-push inflation can reduce output and employment |
| menu and shoe-leather costs | firms spend resources changing prices; consumers spend time and effort searching for value |
| uncertainty and confidence | planning becomes harder, weakening consumer confidence, business confidence and investment |
Central banks may raise interest rates when inflation is above target: saving becomes more attractive and borrowing dearer, reducing spending and demand-pull pressure. Higher rates may also strengthen the currency and lower import costs, but can weaken growth and employment.
Inflation means prices are rising, not that every price rises equally. A lower positive inflation rate means prices rise more slowly; only deflation means the general price level falls.
Classify unemployment and trace its economy-wide costs
Under the International Labour Organization measure, an unemployed person is without work, available to work and actively seeking work. The labour force is employed people plus unemployed people.
unemployment rate=labour forcenumber unemployed×100
| Type | Cause | Example |
|---|---|---|
| cyclical | weak demand during downturn or recession | builders lose jobs when investment falls |
| structural | worker skills or location do not match available jobs, often after lasting industry or technology change | automation replaces routine roles while new jobs need different skills |
| seasonal | labour demand changes predictably during the year | tourism or harvest work ends off-season |
| voluntary | a person chooses not to accept available work | available wage or conditions are rejected |
| frictional | time spent moving between jobs or entering the labour market | a worker searches after leaving one job |
| Impact area | Chain from higher unemployment |
|---|---|
| output and scarce resources | willing labour is unused → actual GDP is below potential |
| poverty | lost earnings reduce household income and living standards |
| government budget | benefit spending rises while income-tax and spending-tax revenue fall |
| confidence | households cut spending and firms expect weaker sales, reducing investment and hiring |
| society | skills can erode; stress, ill health, exclusion and crime risks may rise |
The unemployment rate uses the labour force, not the whole population. Structural unemployment is a mismatch, while cyclical unemployment comes from the economic cycle; a short job search is frictional.
Build and interpret the current-account balance
The current account records international transactions in goods and services and other current flows. In this syllabus, trade in physical goods is visible trade and trade in services is invisible trade.
trade balance=(goods exports+services exports)−(goods imports+services imports)
| Result | Meaning |
|---|---|
| positive balance / surplus | export receipts exceed import spending |
| zero balance | export receipts equal import spending |
| negative balance / deficit | import spending exceeds export receipts |
| Change | Likely current-account effect | Mechanism |
|---|---|---|
| better quality or lower prices of domestic output | improves | exports rise and domestic buyers may switch from imports |
| stronger domestic income growth | worsens | households and firms buy more imports |
| currency depreciation | may improve after adjustment | exports become cheaper abroad and imports dearer at home |
| currency appreciation | may worsen | exports become dearer abroad and imports cheaper at home |
| weak foreign demand or poor domestic competitiveness | worsens | export demand falls |
A persistent deficit can leak demand to foreign producers, weaken domestic output and employment, reduce tax revenue, place downward pressure on the exchange rate, use foreign-currency reserves or require borrowing. Cheaper or higher-quality imports and investment goods can still benefit consumers and productive capacity.
A deficit is a flow over a period, not automatically a debt. The exchange-rate effect is not guaranteed: elasticities, time lags, import dependence and other financial flows matter.
Connect business damage to six environmental responses
| Environmental damage | Business route |
|---|---|
| visual pollution | litter, waste, mining scars or unattractive buildings |
| noise pollution | aircraft, transport, construction or machinery disturb others |
| air pollution | vehicles, power generation and factories emit gases or particles |
| water pollution | mining, agriculture or industry discharge chemicals, waste or heated water |
| Government response | Protection mechanism | Main limitation |
|---|---|---|
| taxation | makes damaging activity dearer and can fund protection | weak if behaviour is unresponsive |
| subsidy | lowers the cost of green technology or cleaner choices | opportunity cost and possible dependence |
| regulation | sets standards, limits or bans | monitoring and compliance costs |
| fines | penalise detected breaches and deter harm | weak if detection is unlikely or fines are small |
| pollution permits | cap legal emissions and may reward firms that cut pollution | cap/allocation can be wrong and emissions must be monitored |
| government parks | conserve ecosystems and provide cleaner recreation and tourism benefits | land, creation and maintenance have opportunity costs |
Match the policy to the source of damage, then judge behavioural response, enforcement, administrative cost and opportunity cost. A mix can combine a firm limit with incentives to exceed the minimum standard.
Providing a park creates environmental and social benefits but does not directly stop emissions elsewhere. More permits usually relaxes a cap; environmental protection requires a sufficiently tight total allowance.
Distinguish poverty from inequality and compare redistribution
| Concept | Meaning |
|---|---|
| income inequality | income is distributed unevenly across people or households |
| absolute poverty | income or resources are insufficient to meet basic needs such as food, shelter and essential healthcare |
| relative poverty | income is substantially below the typical level in that society, limiting participation in its normal living standard |
Governments may reduce poverty and inequality so basic needs are met, living standards rise and society treats people more fairly. Lower deprivation can also improve health, skills, participation and social cohesion.
| Policy | Redistribution route | Trade-off or condition |
|---|---|---|
| progressive taxation | higher-income earners pay a higher percentage; revenue can fund support and services | very high rates may weaken incentives, encourage avoidance or deter investment |
| benefit payments | transfer income directly to eligible low-income or unemployed households | accurate targeting and work incentives matter; spending has an opportunity cost |
| education investment | builds skills and access to better-paid work, addressing long-run causes | effects take time and depend on quality and access |
| healthcare investment | prevents medical costs and poor health from blocking work and living standards | costly and effective provision must reach those in need |
A coordinated package can relieve poverty now through benefits while education and healthcare expand future earning capacity; progressive revenue helps finance it. Judge coverage, targeting, time horizon, fiscal cost and incentive effects.
Reducing absolute poverty does not necessarily eliminate income inequality. Equal incomes are not required to reduce inequality, and a richer country can still have relative poverty.
