Types of unemployment and their causes, inflation and recession: causes, consequences, and government responses, economic growth versus economic development, and the role of trade unions.
Three of the most closely watched indicators of an economy's health are inflation, unemployment, and the rate of growth. Understanding why these problems arise and how government responds to them is a central theme of macroeconomics.
Unemployment is the condition of being willing and able to work but unable to find a job at the prevailing wage rate.
A person is only counted as unemployed if they are: of working age, available for work, and actively seeking a job. Students, retired people, and those not seeking work are outside the labour force and are not counted as unemployed.
| Type | Cause | Example | Policy response |
|---|---|---|---|
| Structural | Industry decline due to technology or global competition makes workers' skills obsolete | Coal miners when power generation shifts to gas; travel agents when online booking replaces them | Retraining programmes, education investment, regional development |
| Cyclical (demand-deficient) | Recession reduces aggregate demand for labour across the economy | Mass layoffs during a financial crisis | Expansionary fiscal and monetary policy |
| Frictional | Workers temporarily between jobs while searching for a better match | A graduate job-hunting; a worker who resigned to find better employment | Improved job information systems; better matching services |
| Seasonal | Work is available only at certain times of year | Agricultural workers idle in the off-season; hotel staff in tourist off-season | Diversifying the economy; retraining programmes; seasonal employment schemes |
| Real-wage (classical) | Wages are set above the market-clearing level (e.g. by trade unions or minimum wage laws), so firms demand fewer workers than are available | Wage agreements above equilibrium create a surplus of labour | Reducing minimum wage, increasing labour market flexibility |
Frictional unemployment is normal and unavoidable in a dynamic economy — there will always be people between jobs. The aim is not to eliminate it but to minimise the time workers spend searching.
Causes:
Consequences:
A trade union is an organisation of workers formed to protect and advance members' interests in wages, working conditions, and employment security.
Inflation is a sustained general rise in the price level, which reduces the purchasing power of money.
Deflation is a sustained general fall in the price level — the opposite of inflation. While it sounds beneficial, deflation encourages consumers to delay purchases (expecting lower prices tomorrow), which reduces spending and can cause a recession.
Demand-pull inflation: When aggregate demand grows faster than the economy's productive capacity. Too much money chasing too few goods. Causes include high government spending, low interest rates, tax cuts, or booming export demand.
Cost-push inflation: When production costs rise, firms raise their prices to maintain profit margins. Causes include rising oil prices, higher wages, increased import costs (through currency depreciation), or supply chain disruptions.
Imported inflation: Rising prices of imported goods feed through into domestic prices, especially for economies heavily dependent on imports.
Excessive money supply growth: When the central bank creates money faster than the economy grows, the result is inflation.
| Policy | Tool | Mechanism |
|---|---|---|
| Contractionary monetary policy | Raise interest rates | Reduces borrowing and spending |
| Contractionary fiscal policy | Raise taxes, cut spending | Reduces aggregate demand |
| Supply-side policies | Investment in training, technology | Increases productive capacity, reducing cost pressures |
Recession is a period of negative economic growth — a fall in real GDP for two or more consecutive quarters. Output, employment, and incomes all typically fall.
Economic growth is an increase in a country's real output of goods and services over time, measured by the percentage change in real GDP. It is a purely quantitative measure.
Economic development is a broader qualitative concept. It includes economic growth but also encompasses improvements in:
Growth can occur without development: a country's GDP may rise due to oil extraction while most of the population remains poor. Development requires that the benefits of growth reach the general population.
Trinidad and Tobago increased its GDP significantly during the 1970s oil boom. This was economic growth. Whether it constituted economic development depends on whether the increased wealth improved education, healthcare, housing, and reduced poverty for the broad population.
If new concrete houses are built across St Vincent, that represents economic growth (increased construction output). Whether it represents development depends on who gets those houses and whether living conditions genuinely improve across society.
Paper 02 questions frequently ask you to distinguish growth from development and give examples. Growth = rise in real GDP (quantitative). Development = improvement in standard of living including health, education, and poverty reduction (qualitative). Growth is necessary but not sufficient for development.
