Causes of recessions

A recession is a period of at least six months (2 quarters) of economic decline which causes a decrease in the real gross domestic product (rGDP)
It can be caused by:
- A fall in any of the factors that influence total demand (consumption, investment, government spending, net exports). These are demand-side factors
- A decrease in the quantity of resources (supply-side factor)
- A decrease in the quality of resources (supply-side factor)

1. Decrease in total demand (demand-side recession)

A fall in total demand is caused by a fall in Consumption (C), Investment (I), Government spending (G), or Net exports (X–M)
Some examples of what may cause this include:
- Higher interest rates reduce borrowing and spending
- Falling consumer confidence leads to less household consumption
- Exports fall due to a global slowdown or stronger exchange rate
A demand-side recession leads to lower output and rising unemployment

2. Decrease in the quantity of resources (supply-side)

This is caused by a reduction in the available factors of production
Some examples of what may cause this include:
- Emigration reduces labour supply
- Natural disasters destroy productive land or capital
- Conflict or political instability disrupts production
A reduction in the quantity of resources reduces the ability of the economy to produce goods and services

3. Decrease in the quality of resources (supply-side)

This occurs when there is a lower productivity or efficiency in the use of existing resources
Some examples of what may cause this include:
- Skills shortages due to underinvestment in education and training
- An ageing or unhealthy population reduces workforce effectiveness
- The poor maintenance of infrastructure slows down production
A reduction on the quality of the factors of production causes long-term declines in productive capacity
The economic decline (recession) caused by supply-side interruptions can be illustrated using a production possibility curve (PPC)

Graph showing trade-off between capital and consumer goods. An inward shift (A) indicates economic decline, while an outward shift (B) indicates economic growth. — Outward shifts of a PPF show economic growth and inward shifts show economic decline (recession)

Diagram explanation

Recession (economic decline) occurs when there is any impact on an economy that reduces the quantity or quality of the available factors of production as depicted by the movement A
- E.g. The Japanese tsunami of 2011 devastated the production possibilities of Japan for many years. It shifted their PPC inwards, causing economic decline

Case study

The 2011 Japanese Tsunami – A Supply-Side Recession

Context

On 11 March 2011, a powerful magnitude 9.0 earthquake struck off the north-east coast of Japan, triggering a massive tsunami. The disaster caused widespread destruction in the Tōhoku region and led to a nuclear accident at the Fukushima Daiichi power plant. Over 15,000 people lost their lives, with many more injured or displaced.

Impact on the quantity of factors of production

Labour – Thousands of workers were killed or injured, reducing the available workforce
Capital – Factories, machinery, transport links, and housing were destroyed, removing productive assets from the economy
Land – Large areas of farmland and coastal industrial zones were flooded or contaminated, reducing usable land for agriculture
Energy supply – The Fukushima disaster forced the closure of nuclear reactors, cutting Japan’s electricity generation capacity

Impact on the quality of factors of production

Labour skills – Skilled workers in specialised industries were lost or could not work, reducing overall productivity
Capital quality – Damaged infrastructure and outdated replacements reduced efficiency in production
Environmental damage – Contamination from the nuclear accident made some land unusable for decades, permanently reducing the quality of that resource
Infrastructure reliability – Disruptions to transport, power, and communications systems reduced the efficiency of economic activity

Outcome for the economy

Japan’s GDP contracted in 2011 as production fell sharply
Major industries such as car manufacturing and electronics experienced significant delays because of damage to suppliers and parts shortages
Recovery required substantial reconstruction spending, but the short-term effect was a supply-side recession, with reduced productive capacity rather than just falling demand
The disaster highlighted Japan’s vulnerability to natural disasters and its heavy reliance on nuclear energy

Consequences of recessions

A recession affects different economic agents in distinct ways, but the main connection is that falling output and incomes reduce spending power, confidence, and investment

Impact on consumers and workers

Consumers	Workers
Lower disposable income reduces the ability to buy goods and services	Job losses as firms cut staff to reduce costs
Falling house prices and share values can reduce household wealth	Higher unemployment rates, especially in luxury industries
Reduced access to credit as banks tighten lending criteria	Increased competition for fewer job vacancies
Decline in consumer confidence leads to postponement of major purchases	Wage freezes or reductions as firms try to survive
Higher risk of poverty, especially for low-income households	Reduced working hours or shift patterns to save on wage bills
Cuts in public services may reduce access to health, education and welfare support	Loss of training and career development opportunities
Emotional strain from financial pressures, potentially affecting mental health	Increased job insecurity and stress in the workplace

Impact on firms and governments

Firms	Governments
Falling sales revenue due to reduced consumer demand	Lower tax revenue from income tax, corporation tax and sales taxes
Underutilised capacity increases average costs per unit	Higher spending on welfare benefits such as unemployment support
Cash flow problems may lead to late payments or defaults	Budget deficits and rising public debt levels
Reduced profitability limits funds for investment and expansion	May need to borrow more or cut spending in other areas
Increased risk of bankruptcy, especially for smaller firms	Political pressure to take action through stimulus measures
Loss of market share if competitors can survive better	Difficulty funding long-term projects due to short-term budget pressures
Delayed product development and innovation	Challenges in maintaining public services during falling revenues
