The economic cycle
Actual economic growth
Changes in total demand may increase the utilisation of resources
and GDP – resulting in a movement from inside toward the PPC
Potential economic growth
Economic growth shifts the economy’s PPC to the right and is caused by
changes in investment, technology, and the quantity and quality of the
factors of production
Recession
A recession is a significant decline in economic activity spread across the
economy, lasting more than a few months, normally visible in real GDP, real
income, employment, industrial production, and wholesale-retail sales..
Possible causes of a recession –
demand-side
Major “negative” demand-side shocks hitting the components of AD
a.
A global economic slump or a deep recession in the country of a major
trading partner such as the countries of the EU (60% of UK trade) and the
United States (15% of UK trade)
b.
A sharp fall / collapse in asset prices e.g. share prices, property prices
c.
A credit crunch where financial institutions cut back the amount of credit
they are prepared to lend to households and businesses and raise the
interest rate on these loans
d.
A large appreciation of the exchange rate which hits demand for
exports, raises import demand and causes the trade balance to worsen
Possible causes of a recession – supplyside
Major inflationary supply-side shocks which affect SRAS
a.
Higher crude oil and gas prices – leading to increased input costs, driving
inflation higher and causing a fall in real incomes for households (less
consumption) and a fall in profits for businesses (less investment and possible
employment cut-backs) – this is known as stagflation
b.
Higher prices for metals and other non-fuel inputs
c.
Surge in foodstuff prices which increase costs and lower profits for food
manufacturers
d.
Other inflationary effects globally such as a sharp rise in inflation in the USA or
China, leading to a burst of imported inflation
e.
If wages remain sticky there is a danger of a wage-price spiral emerging.
Possible causes of a recession –
government policy
Risks of recession arising from deflationary macroeconomic policies such as
higher interest rates or increased direct and indirect taxation
a.
If interest rates are raised to counter higher inflation from the domestic
economy or from overseas – this can cause a fall in confidence, less
spending and a downturn in output and jobs
b.
Taxes may have risen to counter a budget deficit – squeezing real
disposable incomes and demand or perhaps damaging business
investment
Recession causes

Costs and benefits of economic
growth
Main Benefits of Economic Growth
►
Higher living standards – i.e. Real GNI per capita – helps to lift people out
of extreme poverty and improve development outcomes (e.g. rising HDI)
►
Employment effects – sustained growth stimulates jobs and contributes to
lower unemployment rates which is turn helps to reduce income
inequality.
►
Fiscal dividend – higher economic growth will raise tax revenues and
reduce government spending on unemployment & poverty related
welfare benefits
Main Costs of Economic Growth
►
►
►
Risks of higher inflation and higher interest rates
►
Fast-growing demand can lead to inflation – this leads to a conflict between macro
objectives
►
The central bank may decide to raise interest rates to control inflation
Environmental effects
►
More negative externalities such as pollution & waste
►
Risk of unsustainable extraction of finite resources – i.e. fast growing countries may cause a
long-run depletion of natural resources
Inequalities of income and wealth
►
Rapid increases in real national income can lead to a higher level of inequality and social
divisions
►
Many of the gains from growth may go to only a few people
Policies to promote economic growth
►
Government policies to increase economic growth are focused on trying to
increase aggregate demand (demand side policies) or increase aggregate
supply/productivity (supply side policies)
►
Demand side policies include:
►
►
Fiscal policy (cutting taxes/increasing government spending)
►
Monetary policy (cutting interest rates)
Supply side policies include:
►
Privatisation, deregulation, tax cuts, free trade agreements (free market supply side
policies)
►
Improved education and training, improved infrastructure. (interventionist supply side
policies)
Policies for economic growth
Monetary Policy
Monetary policy is the most common tool for influencing economic activity.
To boost AD, the Central Bank (or government) can cut interest rates. Lower
interest rates reduce the cost of borrowing, encouraging investment and
consumer spending. Lower interest rates also reduce the incentive to save,
making spending more attractive instead. Lower interest rates will also reduce
mortgage interest payments, increasing disposable income for consumers
Monetary policy
Evaluation of Monetary Policy
►
Lower interest rates may not always boost spending because people are trying to pay
back debts. In 2009, UK interest rates were cut to 0.5%, but spending remained subdued.
Banks were unwilling to lend because of liquidity shortages. Therefore, although in theory,
it was cheap to borrow, it was hard to actually create credit. After a recession firms and
consumers are lacking confidence and so may not borrow due to the perceived risks
involved. Therefore, this shows monetary policy can be ineffective in boosting economic
growth
►
Another criticism of monetary policy is that cutting interest rates very low could distort
future economic activity. For example, the US cut interest rates following the economic
uncertainty of 9/11. These low-interest rates encouraged people to take on ambitious
loans and mortgages; this was a factor behind the US housing bubble. Therefore cutting
interest rates, at the wrong time, can contribute to a future housing and asset bubble
which will destabilise economic growth. However, in 2009-12, the depth of the financial
crisis means there is no immediate danger of a housing bubble, so it was appropriate to
keep interest rates at zero.
Evaluation of fiscal policy
►
The government can boost demand by cutting tax and increasing
government spending. Lower income tax will increase disposable income
and encourage consumer spending. Higher government spending will
create jobs and provide an economic stimulus.
►
The problem with expansionary fiscal policy is that it leads to an increase in
government borrowing. To finance this extra spending, the government
have to borrow from the private sector.
►
However, if the economy sees a rapid fall in private spending, and a rise in
the saving ratio, expansionary fiscal policy can help provide a boost to
demand in the economy
Fiscal policy - evaluation
Evaluation of devaluation
►
Devaluation can help restore competitiveness and boost domestic
demand. A fall in the exchange rate makes exports cheaper and imports
more expensive.
►
The disadvantage of devaluation is that it can lead to short-term
economic pain. Rising import prices increase inflation and reduce
standards of living. Devaluation is also seen as a sign of economic and
political weakness.
