A recession is defined as a period of negative economic growth. However, there can be different causes and types of economic contraction. Different types of recession will influence the length, depth and effects of the recession.
These are some of the different types of recessions.
1. Boom and bust recession
Many recessions occur after a previous economic boom. In the economic boom, economic growth is well above the long run trend rate of growth; this rapid growth causes inflation and a current account deficit and the growth tends to be unsustainable.
- When government / Central Bank see inflation is getting out of control, they respond by implementing tight monetary policy (higher interest rates) and tight fiscal policy (higher taxes and lower government spending)
- In addition, an economic boom is often unsustainable, e.g. firms may be able to temporarily produce more through paying workers to do overtime, but this might not last.
- Also, in a boom, consumer confidence tends to soar. As a result, there tends to be a fall in the savings ratio and a rise in private borrowing to finance higher spending. The economic boom is financed by rising debt. Therefore, when there is a change in economic fortunes, consumers radically change their behaviour, rather than borrowing they seek to pay off their debt and the saving ratio increases causing fall in spending.
Examples of boom and bust recession
- 1973 recession in UK – following Barber boom of 1972. (Though 1973 recession was also caused by oil price shock)
- 1990-92 recession – following Lawson boom of late 1980s. In late 1980s, UK growth increased to over 5% (annual), causing inflation to rise to double figures. In response, interest rates were increased, house prices fell and consumer confidence collapsed leading to recession of 1991-92.
Features of boom and bust recessions
- Can often be short lived
- If caused by high interest rates, reversing rate increases can cause economy to recover
- Can be avoided by keeping growth close to long run trend rate and inflation low.
2. Balance sheet recession
A balance sheet recession occurs when banks and firms see a large decline in their balance sheets due to falling asset prices and bad loans. Because of large losses, they need to restrict bank lending – leading to a fall in investment spending and economic growth.
In addition, in a balance sheet recession, we also see falling asset prices. For example, a fall in house prices causes a decline in consumer wealth and increases bank losses. These are another factor which causes lower growth.
- 2008-09 recession. In 2008, bank losses led to a fall in bank liquidity and banks found themselves short of cash. This led to a fall in bank lending and it was difficult to get funds for investment. Combined with collapse in confidence, the economy went into recession – despite interest rates being cut to zero.
Features of balance sheet recession
- Can last a long time
- Cuts in interest rates may fail to cause economic recovery due to liquidity trap
- No quick recovery
- More susceptible to a double dip recession
- To avoid a balance sheet recession, we need to avoid a credit and asset bubble. Targeting inflation is not sufficient.
A depression is a prolonged and deep recession, where output falls by over 10% and very high rates of unemployment. A balance sheet recession is more likely to cause a depression because falling asset prices and bank losses have a long lasting impact on economic activity.
4. Supply side shock recession
A very rapid rise in oil prices could cause a recession due to the decline in living standards. In 1973, the world was highly dependent on oil. The tripling in the oil price caused a sharp fall in disposable income and also caused lost output due to lack of oil.
Features of supply side shock recession
- Not very common. The world is less dependent on oil than in 1970s. The rise in oil prices in 2008 was only a minor factor in causing 2008 recession.
- Supply side shock causes Short Run Aggregate Supply (SRAS) to shift left. Therefore, we get both lower output and higher inflation. Often known as ‘stagflation’
Demand side shock recession
An unexpected event that causes a sharp fall in aggregate demand. For example, the short lived recession of 2001 (GDP fell only 0.3%) was partly caused by fall in consumer confidence as a result of 9/11 terrorist attacks (and also end of dot com bubble).
Different shaped recessions
- W shaped recession – refers to a double dip recession, where economy goes into recession shortly after recovering from first
- V shaped recession – refers to a quick recovery after initial recession
- L shaped recession – refers to a period of stagnant recovery after initial fall in GDP. Even though technically the economy may have positive growth (e.g. 0.5%) it still feels like a recession because growth is very slow and unemployment high.
