Aggregate Demand
Aggregate demand (AD) is the total demand for all goods and services produced in an economy in a given
price level and time period.
AD = C + G + I + (X M)
C means consumer expenditure. This makes up the majority of AD in most countries (about 65% of the
total). I means investment in capital goods from firms, and this is the most volatile component of AD. This
typically accounts for 15-20% of GDP, and the majority (75%) is from private sector businesses. G means
government spending on state-provided goods and services. Transfer payments (state benefits) do not
count because these payments are not producing an output they are a transfer of money from one
group to another. X means exports; M means imports. Exports are goods sold to overseas countries and
imports are what the UK buys from foreign countries.
(X M) represents net exports. If this is positive, there is a trade surplus which adds to AD. Conversely, a
negative net exports value means there is a trade deficit, which reduces AD.
Consumer Expenditure
Consumer expenditure is influenced by
The amount ofreal disposable income is the main influence on consumer expenditure. Households and
economies with more disposable income tend to spend more in total than poorer ones. The proportion of
income that is spent is called the average propensity to consume (APC).
Wealth (the value of a stock of assets) affects C. Wealthier people tend to spend more. Wealth can be
spent and can be used to borrow against. It also results in greater consumer confidence. For example, anincrease in house prices will make homeowners feel more wealthy, and this encourages them to spend
more.
Consumer confidence and expectations have a significant influence on consumer spending. When
consumers feel optimistic about the future (expecting good wages and job prospects), then they tend to
spend more. This is why sometimes; a rise in income also raises the proportion of income spent.
Interest rates are also important albeit less significant than consumer confidence. A fall in interest rates
should encourage spending because the cost of borrowing is reduced and there is a lower incentive to
save money. People paying back mortgages and loans will pay back less interest and will have more
money to spend. Net savers (people who save more than they borrow) lost out.
Population demographics (mainly age) affects consumer spending. It is generally thought that the elderly
and young people spend a higher proportion of their income.
Income distribution poorer people spend a higher percentage of their income than richer people.
Government measures that redistribute income from the rich to the poor (e.g. through income tax) are
likely to increase total consumer spending.
Inflation can affect consumer spending. If consumers expect price rises, they may buy more now.
Saving this is not a component of AD but it influences it.

Increased real disposable income can result in households saving a higher proportion of income their
average propensity to save rises. Rising interest rates encourage saving by offering a greater reward for
it. Reduced consumer confidence or increased uncertainty of the future can also result in increased
savings. The age and structure of the population also affects savings.
Investment
Firms invest when they expect returns from the capital goods they buy. Investment is generally
proportional to the anticipated profitability of a certain project/venture.
Changes in real disposable income affect investment. A rise in real incomes is likely to increase demand
for consumer goods and services, which encourages firms to expand their capacity. However, a rise in
disposable income itself is not sufficient enough to make the decision to increase capacity. They need to
make sure that there is a need for the extra investment and whether demand increases enough to make
a profit on the extra investment.
Expectations also determine investment. If firms are optimistic about future economic prospects, theywill be more likely to invest. The extent and speed of expectations are the main reasons for the volatility
of investment.
Capacity utilisation if firms are operating close to full capacity, they are more likely to invest. Spare
capacity (unused capital goods) usually means firms will not invest as they may be able to increase output
without buying more capital goods.
Corporation tax and subsidies increasing subsidies or reducing corporation tax increases the amount of
profit firms can keep, which may drive investment.
Interest rates affect investment. A rise in interest rates may decrease investment because theopportunity cost of investment is increased (money could be saved). The higher interest rates increase
the cost of borrowing and may discourage some investment projects. A higher interest rate may reduce
consumer spending, which will affect the expected return on the investment.
Advances in technology mean that firms can produce better quality products more cheaply, which will
result in a higher expected profit, because the unit cost is reduced and there will be a higher demand for
the better products. The price of capital equipment also affects investment. Cheaper capital goods make
it more viable for firms to expand their capacity.
Government spending
The governments view on the extent of market failure and its ability to correct it affects its spending. In
countries where state intervention is high, government spending is likely to be greater than in countries
with a free market economy. For example, government spending in Sweden accounts for a higher
proportion of its AD than government spending in Singapore.
The level of economic activity influences government spending. A high unemployment rate may
stimulate increased spending in a bid to raise aggregate demand and output of the economy. In contrast,
high inflation may cause the government to reduce spending.
Governments may increase spending in order to increase its political support. War, terrorism rising crime
and other threats may also increase government spending.

Net Exports
Real disposable income abroad affects net exports. An increased income abroad is likely to increase
exports due to the increased demand. The US is a major trading partner to the UK; if incomes in the US
rise, they will buy more goods and services some of these from the UK.
In real disposable income at home rises, exports may fall as firms could divert some products from the
export market to the home market to meet the rising demand.
The domestic price level affects net exports. If price levels rise too much, households and firms will
switch from domestic products to ones made in other countries (which increase imports).
Exchange rate changesaffect imports and exports. A fall in a countrys exchange rate reduces the prices
of exports and increases the price of imports.
Government restrictions on free trade affect net exports. If a country removes trade restrictions, then
other countries net exports may rise. If the USA removed tariffs on Chinese steel, China could export
more to the USA.
Aggregate Demand shocks
Unexpected events cause changes in aggregate demand. These unplanned events are called shocks.
One of the causes of fluctuations in the level of economic activity is the presence of demand-side shocks.
Some causes of demand-side shocks are:
A capital investment boom e.g. a construction boom to increase the supply of houses orcommercial/industrial buildings.
Exchange rate fluctuations. These affect net export demand and have knock-on effects on therest of the economy e.g. output, unemployment and incomes.
A consumer boom abroad in a country which is a major trading partner. This boosts demand forexports of our goods and services.
Large boom or slump in a specific market e.g. housing or share prices. An unexpected cut or rise in interest rates.
Shocks to aggregate demand have a big impact due to the interdependence of the worlds economies.
Countries which trade more with other countries are likely to feel a greater impact from a shock to their
economy compared to a country which trades very little with other countries.
Aggregate Demand Curve
Why is there an inverse relationship
between real GDP and price level?
Real incomes as price level rises,
the real value of peoples incomes
fall. The rise in the price level results
in consumers being able to buy less

Aggregate Supply
Aggregate supply (AS) is the total output of goods and services that producers in an economy are willing
and able to supply at different price levels in a given time period.
In the long run (LRAS), the aggregate-supply curve is assumed to be vertical. It is closely linked with the
production possibility curve. In the short run (SRAS), the aggregate-supply curve is assumed to be upward
sloping. The SRAS curve is upward sloping because higher prices for goods and services make output
more profitable, and enable businesses to expand their production.
SRAS shows planned output when prices can change but prices of all factor inputs are held constant e.g.
wage rates and state of technology. The SRAS starts off as perfectly elastic. This is at a point where
unemployment is high and output is low, which means firms have a lot of spare capacity. More can be
supplied without increasing the price level. Real GDP is lower than potential GDP.
It becomes increasingly inelastic (unresponsive to changes in price level) as resources become scarcer.
There is a diminishing return because firms have to employ less productive labour and machinery, and
the unit costs of production increase.
At Yfc, producers are producing at full capacity it is not possible to produce anymore irrespective of the
increase in price level.
Shifts in short run aggregate supply
The main cause of shifts in the SRAS curve is due to the changing prices of the factors of production. A
change in the prices of commodities and raw materials affects the firms costs. These may be influenced
by exchange rates. An exchange rate fall increases the cost of exports. A change in the cost of labour
(wages) also affects the firms costs in a similar way.

Changes in the governments fiscal policy relating to taxation and subsidies have effects on producers.
Increased taxation (could be through VAT or corporation tax) will cause an inwards shift in SRAS due to
the higher cost of production.
Long Run Aggregate Supply
Most supply-side policies are intended to improve the long term performance of the economy, but they
usually have short term effects too. LRAS is assumed to be independent of price level other factors
affect this. It is determined by the productivity of the factors of production (an expansion in this increases
LRAS). Changes in technology that benefit the whole economy also influence LRAS.
Macroeconomic equilibrium is when AD and AS are
equal. When these are equal, there is no reason for
output and price level to change and the economy isstable.
There may be situations where AD is greater than AS,
and the economy cannot cope with the increased
demand. The economy may have full employment.
This pushes up the price level due to shortages. SRAS
is inelastic in this case.

The result of this is that the price level will increase if AD
increases. This is shown on the diagram to the right.
Macroeconomic equilibrium shifts to a point where a
greater quantity of goods and services are produced at a
higher price level. But the increase in price level will be
much greater than the increase in quantity due to the
inelasticity of the SRAS.
Anything that shifts AD or AS will cause a change in the
macroeconomic equilibrium.
The Circular flow of income shows the movement of spending
and income throughout the economy.
However, in reality, not all income is spent. Income that is not
spent on domestic output is said to leak out of circular flow.
These are known as leakages. Injections increase aggregate
demand, which cause additional spending.
The 3 main leakages are taxes (T), savings (S) and spending in
imports (M). Examples of injections are investment (I),
government spending (G) and exports (X). In macroeconomic
equilibrium, leakages equal injections, meaning that output is not changing.
The multiplier effect states that the initial injection/increase in AD will have a much greater effect on the
final AD rise. This is because of the knock-on effects that a change in AD has. Injections of demand into
the circular flow of income stimulate further spending.
This effect does assume that there is spare capacity for extra output is produced. Therefore, the effect is
more likely to be seen if an injection is made when AD is already at a lower level. Elasticity of SRAS also
determines the multiplier effect. Inelastic supply is likely to just increase the price level rather than
output.
Changes in AD and AS
The 3 main influences in the effect of a change in AD on the output, unemployment and inflation are the
size of the initial change, size of the multiplier effect and the original level of economic activity. If the
economy is operating with a lot of spare capacity, an increase in AD is likely to increase output and
reduce unemployment without affecting the price level. If macroeconomic equilibrium changes to a point
of more shortages, a rise in AD will increase both the price level and output. If the economy is at full
capacity, only the price level will increase as supply cannot be increased.
Changes in AS also depend on the size of change and initial level of economic activity. Increasing AS
occurring when the economy is close to/at full capacity will raise output and lower the price level. If the
economy is operating at a high level of unemployed resources, an increase in AS may not affect the
economy at all. In this case, only potential output increases; not actual output. The price level will remain
the same.

In most economies, both AD and AS will change over time. If an AS increase can match an AD increase,
the effect on price level of the two changes will cancel each other out, meaning that the output increases
without affecting the price level, thus reducing
inflationary pressures.
However, if AD grows more rapidly than productivecapacity, inflation will occur. The higher output
comes at a cost of inflation, and this is
unsustainable. The economy is overheating. This is
similar to the situation in countries like India. This
can be shown in the diagram on the right.
Some events affect both AS and AD, for example,
government spending on increasing worker
productivity or immigration of people of working
age.
Output gap this is when an economy is not producing at full capacity. A negative output gap is when
production is below full capacity. A positive output gap is when an economy is producing more than
potential output this is only in the short term and is not sustainable unless AS shifts outwards. This is
achieved by overtime and overusing machines. Countries with positive output gaps usually experience
inflation.
Economic Growth
Between the years 1992-2007, the UK experienced the longest period of stable continuous economic
growth on record. This growth has been combined with low unemployment and low stable inflation.Aggregate supply has been increasing with aggregate demand, which has helped keep growth stable. The
UK has experienced a large current account deficit due to a large import of goods.
Economic growth is best defined as a long-term expansion of the productive potential of the economy. It
is measured by the annual change in real GDP (in the short term).
Both supply and demand factors impact on economic growth. Demand-side factors, such as consumer
and business confidence and aggregate demand cause temporary impacts on growth. Supply-side factors,
such as population and productivity growth, technology advancements and growth of stock capital,
impact on long-term aggregate supply.

This can also be illustrated on a PPC shifting outwards a greater number of goods can be produced.
Benefits of economic growth
An increase in GDP per capita (total GDP divided by the population) increases the livingstandards. Strong economic growth can reduce poverty levels in developing countries.
Economic growth decreases unemployment and raises employment. Economic growth increases government revenue via taxation, which allows more government
spending on health, infrastructure and education.
The investment accelerator effect Rising demand and output encourages more investment oncapital goods, which increases long run aggregate supply and sustains economic growth.
Economic growth increasesbusiness confidence and has a positive impact on the economy. Could lead to environmental benefits. Economic growth may drive innovation in richer
countries, which may result in more money being invested in greener technology, which reduces
energy consumption per unit of GDP.
Negative effects of economic growth
Economic growth also has its risks. If the economy grows too quickly, problems can occur. If demand rises more than LRAS, rising inflation is a risk. Inflation puts pressure on interest rates
to rise and cause a loss in competitiveness in international markets.
Economic growth has a massive environmental impact. Environmental damage can affect ourquality of life and it limits our sustainable rate of growth.
Economic growth can cause increased income inequality. The gap between rich and poor canwiden, resulting in relative poverty. Income inequality is linked to social and health problems.

Point A barely represents the necessities. If a poor country tries
to increase production in capital goods by shifting from A to C,
there is a reduction in the number of consumer goods available.
This can be damaging to a country already suffering from a lack of
basic essentials.
The richer people will benefit as they can invest in the increased
production. This may increase the gap between the rich and poor.
If a country operates at full capacity, and discovers new resources
or improves efficiency of existing resources, the PPC shifts
outwards.
Current economic growth is not sustainable. Valuable finite resources are rapidly being depleted, and
some renewable resources are being over-consumed. The main environmental issues are:
Pollution of the environment and increasing amounts of waste. Over-population, which is putting pressure on resources. Loss of bio-diversity. Depletion of global resources and the impact of global warming.
Economic growth needs to be more sustainable. Sustainable economic growth meets the needs of the
present, and can continue without compromising the ability of future generations to expand
productive capacity. More developed countries are aiming for sustainable development, and the UK
publishes an annual report on progress towards the goal of sustainable development.
The current Government supports the concept of sustainable development and focuses on four mainobjectives:
Social progress which recognises the needs of everyone: Everyone should share in the benefitsof increased prosperity and a clean and safe environment. Needs must not be met by treating
others, including future generations and people elsewhere in the world, unfairly.
Effective protection of the environment: We must limit global environmental threats, such asclimate change to protect human health, wildlife and landscapes from hazards such as poor air
quality and toxic chemicals.
Prudent use of natural resources: Non-renewable resources should be used efficiently andalternatives should be developed to replace them in due course. Renewable resources, such as
water, should be used in ways that do not endanger the resource or cause damage.
Maintenance of high and stable levels of economic growth and employment, so that everyonecan share in high living standards and greater job opportunities.
Unemployment
Unemployment people are people who are willing and able to work and are actively seeking work but are
not employed. The 2 main measures for unemployment in the UK are claimant count and the labour
force survey.
The claimant count is then number of people claiming unemployment benefits. These figures are lower
than the true unemployment level as not all unemployed people can claim benefits. The labour force

goods.

survey totals all people who have looked for work in the past month and are able to start in two weeks.
The figure also includes those who have found a job and are waiting to start in the next two weeks.
On average, the labour force survey has exceeded the claimant count by about 400,000 in recent years.
This may be due to a sampling error in the data. However, the survey is the internationally agreed
definition of unemployment and it is the best for cross-country comparisons of unemployment.
Causes of unemployment
Frictional unemployment is short term unemployment. It occurs when workers are between different
jobs e.g. university graduates taking a short break after education.
Structural unemployment is long term unemployment caused by the decline of certain industries and
occupations due to changes in demand. Globalisation has increased international competition, which has
caused a decline in Britains manufacturing industry. The workers in these industries do not have skills
that match the requirements of new job opportunities, and they have found it hard to get new jobs
without retraining. There is a problem ofoccupational immobility of labour.
Cyclical unemployment occurs when aggregate demand is low. The demand for labour is lower as less
output is required to meet the lower AD.
Seasonal unemployment is periodic unemployment in certain times of the year due to people working in
industries where they are not needed all year round e.g. ice-cream men.
Costs of unemployment there are economic and social costs of unemployment.
The unemployment face a loss of income, and the majority experience a decline in living standards. This
causes a decrease in consumer spending and AD, and may cause further unemployment.
Unemployment causes a fall in potential national output and represents an inefficient use of scarce
resources. If people leave the labour market permanently due to a loss of motivation of searching for a
new job, there is an impact on LRAS, and could damage economic growth potential.
Fiscal costs the government loses tax revenue and increases spending on welfare payments. The result
can be an increase in the budget deficit, and the government may have to increase taxation or cut back
on public spending. This will put strain on those who are still employed. There is an opportunity cost of
increasing spending on benefits.
Social deprivation is linked with rising unemployment. Areas of high unemployment experience falling
real incomes and increases in inequalities of income and health. Crime is also closely correlated with
unemployment, which will increase government spending on policing.
To firms, unemployment does have some advantages. There is downward pressure on wages as
unemployed people may be willing to work for less. There is also a greater availability of labour, and
firms may get skilled labour that adds value to the firm. If there is low unemployment, there is upwards
pressure on wages, and firms are forced to increase prices (inflation).
Government policies on unemployment

Some countries are more successful than others at reducing unemployment. In the long term, both
demand and supply side policies need to be used so that new jobs are created and skilled workers take
those jobs. The most effective policies are ones that:
Stimulate an improvement in the human capital of the workforce. Then, unemployed peoplehave skills to take up new jobs. Policies usually concentrate on improving occupationalimmobility of labour so that structural changes can be handled.
Improve incentives for searching and accepting work. This may require changes to the tax andbenefits system, for example, reducing the lowest band of income tax or raising the income tax
threshold (so that lower paid jobs seem more attractive). Alternatively, benefits could be cut for
those unemployed; however, this is hard to do due to the complex nature of unemployment.
Employment subsidies. Government subsidies for firms taking on long-term unemployedworkers will create an incentive for a firm to expand the size of their workforce. They can offer
subsidisedjobs and training, and they can stop benefits for those who dont comply.
Achieve sustained economic growth. Aggregate demand needs to be sufficiently high so thatbusinesses are looking to expand their workforce small growth is unlikely to have a largeimpact. Also, not every rise in AD needs to be met with an increase in the workforce increasing
productivity (output per worker) can also meet some rises in AD.
Policies used in the UK for unemployment:
DEMAND SIDE POLICIES SUPPLY SIDE POLICIES
Employment subsidies for firms taking on long
term unemployed (New Deal)
Welfare reforms, including lower tax rates and
introduction of tax credits.
Financial assistance for overseas inward
investment.
Policies to promote entrepreneurship and growth
of small/medium sized businesses.
Monetary policy: low interest rates have allowedAD to grow despite global recession. Fiscal policy is
also boosting AD as the budget deficit increases.
Increased spending on education and attempts toincrease the private sector spending on training.
Evaluation points on policies
There are always cyclical fluctuations in employment. If growth can be sustained and government
policies can avoid a large output gap, then it should be possible to create a steady flow of new jobs.
Both demand and supply side policies have to be used to decrease unemployment in the long term.
Boosting demand if structural unemployment is a major cause is ineffective as it is not solving the
problem. If demand is stimulated too much, there is a risk of inflation.
There will always be frictional unemployment. It may help to have a small surplus pool of labour
available. A disadvantage of full employment is that if firms want to expand their labour force, there is a
massive inflation risk as there is a shortage of labour.
Trends in UK employment
Before the global recession, the UK was reducing the
unemployment rate, and many factors contributed
to this. There has been a slower population growth,
resulting in a slower rate of new people entering the
labour market. Expansion of higher education has
meant that people are entering the labour market

later, which also puts less pressure on the number of new entrants into the labour market. Lots of jobs
have been created as a result of foreign investment. There has been increased investment in worker
training, which has reduced occupational immobility of labour.
One problem with the UK is that many adults are not as educated as in other countries. Because of this,
employers reduce their standards when recruiting new workers, and this has cut back on quality level.
Inflation
Inflation measures the change in the general price level over a period of time. Inflation is a sustained
increase in the average price level. When prices rise, the value of money is decreasing because less can
be bought for the same amount of money.
Measuring inflation
Inflation can be measured using multiple methods. The main measure is the consumer price index (CPI).
It measures the changes in price of a representative basket of consumer goods and services. The CPI is a
weighted price index the proportion of peoples expenditure on a certain type of good has the
equivalent weighting in the CPI (this is found out by the Family Expenditure survey). A base year has to be
selected this is a year where nothing unusual happens.
Another index is the retail price index (RPI). It differs from the CPI in methodology and is used for
adjusting pensions and other benefits. The RPI includes things like mortgage interest payments and
council tax.
The difficulty in measuring inflation is that the numbers may not reflect an accurate picture of what is
happening in the economy. Housing costs vary greatly between different people, and it accounts for 16%of the index. A price may rise due to a higher quality product being offered, which is hard to be
accounted for in the figures. The measures also tend to overstate inflation as they measure a fixed basket
of goods, and the measures dont take into account peoples ability to alter what they buy during t he
year. The CPI is slow to respond to the emergence of new products and services.
Types of inflation
Cost push inflation occurs when firms increase prices following an increase
in production costs. The SRAS shifts inwards, causing a contraction in AD.
Macroeconomic equilibrium shifts to a point where less output is sold at a
higher price.
Some causes of cost push inflation are:
An increase in the price of raw materials (may be caused byinflation in other countries or a weakening of the GBP).
Rising labour costs (increasing wages are greater than increases in productivity) Rising indirect taxes may also cause a firm to increase the price. The price elasticity of demand of
individual products impact whether the tax is passed on to consumers.
Cost push inflation is more likely to occur when unemployment is low as there is a lower availability of
skilled labour.

Demand Pull inflation occurs when AD exceeds AS. At lower GDP levels, when there is spare production
capacity, firms can easily expand output to meet increases in demand, resulting in a relatively elastic AS
curve. AS becomes increasingly inelastic as output tends towards full capacity.
As employment grows, demand is likely to become more inelastic, which allows firms to pass on huge
price rises without a significant fall in demand.
Demand-pull inflation is likely when there is full employment of resources and when SRAS is inelastic. In
these circumstances an increase in AD will lead to an increase in prices. Causes in demand pull inflation
are related to increases in AD. Reduction in taxes, increased consumer confidence, exchange rate
depreciation, fast economic growth in UK export markets and a rapid increase in the money supply (may
be due to low interest rates and more borrowing) all contribute to increases in AD.
Impacts of inflation
A higher inflation will cause a loss in price competitiveness on international markets. However, this is at
a given exchange rate. Exchange rate depreciation can restore this. A rise in inflation can also decreasethe UKs share of the export market, which reduces economic growth and employment level.
Price rises can result in wage-price spiralling. Workers will demand a higher salary to keep their real
standard of living. If the increase in wage is greater than the increase in productivity, firms may increase
prices due to lower profit margins being offered. The process can repeat and inflation could get out of
control. Menu costs are the costs of changing prices due to inflation (printing new catalogues can cost a
lot of money).
Inflation can result in a reduction in the real value of savings . If inflation is greater than interest rates,
then real interest rates are negative and people are effectively losing money. People have to search out
for which financial institutions are offering the best interest. Households will incur shoeleather costs
costs in terms of the extra time and effort involved in reducing money holdings.
Consumers and businesses on fixed incomes will lose out. Some pensioners are on a fixed pension, and
inflation will reduce the real value of the income. Pensions are normally adjusted for inflation.
Inflation usually results in higher interest rates, which are designed to curb inflation. Higher interest rates
discourage spending and should reduce inflation.
Fiscal dragpeoples income being dragged into higher tax bands due to tax brackets not being adjusted
in line with inflation.
Business planning and budgeting can be harder if inflation is high and volatile. If inflation is high and
volatile, firms are more likely to want a higher return on any project to accommodate a potential cost
increase.
Inflationary noise is the distortion of price signals caused by inflation, and it leads to increased allocative
inefficiency.
However, inflation can have some benefits. If inflation is demand pull inflation at a low and stable rate, a
steady rise in price level may encourage firms to increase output. An increase in pay due to inflation,
despite increasing prices, has a positive psychological effect on workers.

Cost push inflation tends to be more harmful for an economy than demand pull inflation. Cost push
inflation is often accompanies by a fall in GDP and employment. High rates of inflation cause problems
due to the massive shoeleather and menu costs. It becomes more difficult to judge what the best buys
are. Unanticipated inflation is more harmful than anticipated inflation, because it results in uncertainty
and can result in random redistribution of income.
Government policies
Controlling inflation has been a key objective of many governments macroeconomic policy.
Inflation targeting can lower the chance of both types of inflation. If people are convinced the central
bank has the ability to meet its target, then they will act in a way that doesnt cause inflation. It makes
monetary policy more transparent and the central bank more accountable.
The government can reduce cost push inflation in many ways. If excessive wage rates are the reason,
then they may try and restrict wage rates. It can easily control wages in the public sector by changing
government spending. The introduction of an incomes policy, e.g. limiting wage increases of a certainpercentage, can reduce inflation without causing unemployment. However, it may crease inflexibility in
labour markets. Firms wanting to expand will be limited as to how much they can offer workers. They can
also lower firms costs by reducing corporation tax or providing subsidies. This enables firms to reduce
costs without raising prices. However, there is a danger that firms may become dependent on these
measures and not try to minimize costs.
Reducing demand pull inflation involves slowing growth of AD/decreasing AD. The government could
raise income tax. This will mean people have less disposable income, leading to a reduction in the
amount of disposable income. The main anti-inflation measure is changing interest rates. Increasing
interest rates will reduce AD by reducing consumption, investment and next exports while increasing
savings.
Supply-side policies include those that seek to increase productivity, competition and innovation. These
cause a shift outwards of LRAS, and reduce cost push inflation. This is mainly for the long run. If
productive potential increases with AD, the economy can grow without the price level rising as the
increases in AS and AD have opposing effects on price level, which cancel out.
Why has UK inflation remained fairly low?
The last 12 years has been a period of low stable inflation in the UK, and there are many factors
contributing to this. There has been low wage inflation in the labour market. There has also been low
global inflation, and the UK has experienced this too. The monetary policy has been effective in keeping
AD under control through changing interest rates. The strength of the exchange rate has helped keep
costs of imported goods low and it squeezes demand for UK exporters. UK businesses are facing severe
foreign competition due to the emergence of many countries economies. This has helped create an
incentive for UK firms to maintain low costs and seek efficiency.
It has been a combination of demand and supply factors that have kept UK inflation low.
Balance of Payments
The balance of payments (BoP) is a record of all the financial transactions between a country and the rest
of the world. The accounts are split into 2 sections. The current account measures trade in goods and
-

15
services in and out of the UK. The capital account tracks capital flows in and out of the UK, including FDI.
BoP is an important measure of the relative performance of the UK in the global economy.
If a country has a current account deficit, then the capital account has to balance this in order to finance
the additional expenditure on exports. Capital account flows can be increased in the short term by
offering an attractive interest rate. Alternatively, the country could get foreign direct investment.
The UK has had a trade deficit in many years in
the trade of goods (visible trade), mainly due to increased foreign competition in the manufacturing
sector. However, it has a surplus in the trade in services (invisible trade). Britain has a strong trade base
in services with over 30% of total export earnings come from services. It has a comparative advantage in
financial services over the rest of the world.
A current account deficitis when a countrys net imports exceed net exports.
Underlying causes
Strong consumer demand household spending has increased more than supply has. This results in a
high level of demand for imported goods and services.
The demand for imported products has a high income elasticity of demand.
The UKs strong exchange rate means imports are preferred over domestically produced goods.
The weakness of the global economyhas caused exports to decrease. Over half of the UKs exports go to
members of the Eurozone, which has witnessed slow economic growth.
UK trade balances have been affected by shifts in comparative advantage in the international economy.
The rapid growth of china has shifted the manufacturing sector over there.
The availability of goods from other countries at a relatively cheap price causes a substitution effect
from British consumers.
The trade deficit of the UK is mainly due to structural factors rather than cyclical factors.
Britain has many supply-side deficiencies in non-price factors. There is a lack of capital investment
compared to other countries. There is a low spend on research and development, which results in poor
innovation from British companies. The UK manufacturing sector has been in long-term decline.

There are more leakages in the economy, resulting in less aggregate demand. There is a contraction in
short run aggregate supply, which results in a decreased GDP.
There will be an increase in structural unemployment if exporting industries require less labour and if UK
businesses lose market share and output to cheaper imports from overseas.
There will be a dip in business confidence and capital investment if overseas demand falls.
There is a reduction inflationary pressure. If the UK imports more, then AD falls, and macroequilibrium
shifts away from full capacity. Reduced inflationary pressure may cause the Bank of England to reduce
interest rates in order to stimulate macroeconomic activity.
Why should we be relaxed about a current account deficit?
A trade deficit is not always bad. A short-term trade deficit is OK if it means that a country is importing
lots of goods to boost standards of living in the country. However, in the long-term, a trade deficit may be
a symptom of a weak economy.
If some of the deficit is due to strong consumer demand, the deficit will partially self-correct when the
economic cycle turns and there is a slowdown in spending.
Some of the deficit may because of increased imports of new capital and technology. This will have a
beneficial effect on productivity and competitiveness of producers in home and overseas markets.
Capital inflows balance the books. If a country has a stable economy, inflows of capital can finance the
current account deficit. The UK has run an average annual current account deficit of 10 billion from
1992-2004 and yet the economy has also enjoyed one of the longest sustained periods of growth and
falling unemployment during that time.
A continuous trade deficit may be a sign that a country is able to continually attract capital inflows.
However, this can be risky as capital inflows can be stopped at any time.
Why should we be concerned about a current account deficit?
A trade deficit may be due to structural weaknesses. There is a loss of competitiveness in overseas
markets, insufficient investment in new capital or a shift in comparative advantage towards other
countries.
A trade deficit is a sign of an unbalanced economy, where consumers are spending too much contrasted
with a weaker industrial sector. If consumers carry on overspending, there is a danger that an increased
demand for imports will be accompanied by a surge in household debt.
A current account deficit has to be balanced by the capital account, and a country cannot keep relying
on this. Investors may lose confidence and take money out. They may demand higher interest rates,
which decreases consumption.
A large amount of imported goods puts downward pressure on the exchange rate as there is a large
supply of the currency on the world market. This may result in an interest rate increase and also cause
inflation on goods imported into the country.
How can a high value currency result in a country having a trade deficit?

A strong currency will mean countries buying from them will experience high export prices. High export
prices may discourage demand. A strong currency means import prices being low. The low import prices
may increase demand for products being imported. A lower export revenue and higher import
expenditure will result in a negative balance of payments.
Is a depreciation in its exchange rate is likely to improve a countrys trade in goods balance?
Depreciation is a fall in the exchange rate due to market forces. Depreciation will lower export prices and
raise import prices. Export prices will lower and so raise demand for exports. Import prices will rise and
therefore lower demand for imports. In theory, this should improve a countrys trade in goods balance.
However, it depends on the extent of the depreciation. A small depreciation is unlikely to have any
significant effect. It also depends on the increase in the costs of production by the higher price of
imported raw materials (due to the depreciation).
Exchange Rates
Exchange rate is the price of one currency in terms of another currency.
The UK operates with a managed floating
exchange rate, which is similar to most
currencies. This means that exchange rate is
determined by forces of supply and demand.
An increase in the demand for GBP in the
foreign exchange markets, in the absence of
other offsetting factors, will force sterling
higher against other currencies. The demand
will shift outwards from D1 to D2. Equilibrium
shifts from S1D1 to S1D2. At this point, more US
dollars need to be paid to gain the same
amount of GBP. The GBP is getting stronger.
What influences supply and demand for
exchange rates?
If UK products are internationally competitive, demand is likely to be high and supply is likely tobe low. Foreigners want to buy GBP to buy UK products, and UK citizens will not be selling many
pounds to buy imports. Labour productivity, investment and relative inflation rates affect
international competitiveness.
Changes in income abroad influence exchange rates. If incomes are rising abroad, demand for UKproducts is likely to increase, which will make the GBP stronger.
Rising domestic incomes may decrease the exchange rate. The supply of GBP on forex marketswill increase as pounds are sold to import products into the UK.
A rise in UK interest rates will increase demand for GBP. Foreigners will want to buy GBP to openbank accounts in the UK to benefit from the higher interest rates.
The attraction of FDI affects exchange rates. If the UK has a strong economic performance, askilful labour force and favourable government policies, the demand for GBP will increase asforeign companies will want to set up operations in the UK.

Speculation is a key part of determining exchange rates. If speculators sell some of their holdingsin response to a fall in exchange rates, they are likely to drop even further. However, if they
expect that the falling rate will rise again soon, they will buy the currency, thereby preventing a
large fall.
Effect of an exchange rate change on export and import prices
A fall in exchange rate (depreciation if by market forces) will reduce the price of UK produced goods for
countries with foreign currencies. Most exporters are likely to let export prices fall in line with the
exchange rate as selling at a lower price should increase sales. Exporters selling price inelastic products
are likely to leave prices unchanged (they will receive more money for a product).
Exchange rates and interest rates
Changes in interest rate are closely linked to exchange rates. If the GBP gets stronger, this discourages
exports and encourages imports, leading to a fall in AD. Interest rates may then fall to encourage
spending. A fall in interest rate reduces the exchange rate because the return on money kept in UKfinancial institutions is lower. An outflow of funds increases the supply of currency, which reduces the
exchange rate.
There is an exception to the proportional relationship between interest rates and exchange rates. A cut in
interest rates may make foreigners confident about the prospects of economic growth in the UK. This will
push up the value of GBP as they are likely to buy more.
Exchange rates and inflation
An appreciation of the exchange rate will reduce the price of imported goods. This may have a direct
impact on consumer spending, as cheaper imports have a deflationary effect. Firms will also havereduced costs, and may pass this down to the consumer, which also has a deflationary effect. This will
only have an effect in economies that import a lot of goods.
An exchange rate appreciation makes UK goods more expensive to other countries. If exports reduce,
then exporters may cut their prices, reduce output and cut-back employment levels. A fall in export
demand will reduce real national income relative to potential output this might lead to a negative
output gap. This puts downward pressure on inflation.

Changes in the exchange rate and the macroeconomy
An exchange rate reduction is likely to improve balance of payments. A fall in export prices will rise in
greater revenue if demand is elastic. A rise in import prices will reduce expenditure on imports if demand
is elastic.
Lower exchange rate will also increase aggregate demand. However, there is a risk of inflationary
pressure. This is because the price of imported raw materials will rise, thereby increasing the cost of
production. Domestic firms are under less pressure to keep costs low due to reduced competition from
foreign firms.
Advantages of a strong currency
Cheaper imports for domestic consumers. This boosts living standards in the short term. Lower costs for producers who import raw materials. The AS curve shifts outwards. If a country
can buy more productive technology, LRAS may also shift outwards.
Lower inflation because domestic suppliers face stiff competition from international firms.Cheaper prices on imported food/drink also reduce inflation.
Lower inflation = lower interest rates, which encourages consumer and capital spending.Disadvantages of a strong currency
Increase in trade deficit because there is increased expenditure on imports, and exporters areless internationally competitive due to the strong currency.
If exports fall, there will be a slower economic (GDP) growth. Falling exports leads to a fall in business confidence and capital investment.
Factors being assumed to be constant
The government can counter-balance these effects by changing the fiscal or monetary policy.

Businesses do respond to a high exchange rate. They outsource components overseas and seek
productivity/efficiency gains to keep costs down. Many businesses cut their export prices in order to
maintain international competitiveness.
Application of macroeconomic policy instruments
The government can use a range of policy instruments to achieve macroeconomic objectives. The policies
used will change according to the desired outcomes and the effectiveness of each one.
Fiscal Policy
Fiscal policy covers spending, borrowing and taxation decisions of a government.
Goals of the fiscal policy are:
Investing money in infrastructure, healthcare and education (impacting LRAS). Redistribution of wealth by creating a safety net for poorer people through welfare. Macroeconomic stability by maintaining aggregate demand (AD).
Increasing government spending and reducing taxation (direct/indirect) can both stimulate a boost in AD.
Government spending is a component of AD. Higher spending is likely to have a multiplier effect, causing
a larger rise in AD. Cutting income and corporation taxation will increase disposable income (which
increases consumer spending) and encourage investment respectively.
To achieve changes in the private sector, the government can use discretionary fiscal policy, which is
when a government actively influences AS by changing tax or expenditure. Automatic stabilisers are
forms of spending and tax that change automatically to dampen economic fluctuations without changing
government policy. For example, during economic boom, JSA falls as less people claim it and taxation
increases, which takes more money out of the circular flow of income this is not because the
government changes spending.
Government spending can be split into:
Capital expenditure (hospitals, schools and roads). Current spending (running of public services e.g. teachers, NHS, medicines). Transfer payments.
Some key terms
Reflationary policy measures designed to increase aggregate demand.
Deflationary policy measures designed to reduce aggregate demand.
Progressive tax a tax which takes a higher percentage of income as income rises.
Regressive tax a tax which takes a higher percentage of income as income falls.
Recession two successive quarters of negative real GDP growth.
Exchange rate the price of one currency in terms of another.
Output Gap the difference between potential GDP and actual GDP.

Debt interest payments payments to holders of government debt.Expenditure on health and education is affected by government priorities and changes in the
demographics of the population. The ageing population in the UK is putting immense pressure on health
spending. There are also increased expectations to develop new technology in medicine to do more
complex operations and to increase efficiency.
Changes to the fiscal policy can also impact on supply-side capacity (LRAS) of the economy, and can
contribute to long term economic growth. Capital spending by the government (e.g. infrastructure)
increases investment in the economy. Lower corporation tax also stimulates investment. Investment into
education improves the quality of labour, and enables the UK to stay competitive. Government spending
can also encourage research and development, which increases LRAS.
Every year, the Chancellor of the Exchequer presents a budget. It includes spending and tax reviews. A
budget position shows the relationship between government spending and tax revenue. A budget deficit
is when government spending exceeds tax revenue. In this case, borrowing is required. A budget surplus
is when tax revenue is greater than spending. This allows the repayment of debt. Both cyclical and
structural factors can affect this.
Types of tax
Income tax is the most important source of tax revenue in the UK. Income tax is a direct and progressive
tax. The percentage and amount rises with income. Value added tax (VAT) is the second most important
tax. It is imposed on the sale of goods and services, but at different rates. The standard rate is 20%, but
some goods and services are either exempt from VAT (most food, childrens clothing and books, or
services like gambling and sports) or have a reduced rate of 5% (energy saving products or smoking
cessation items).
Monetary policy
Monetary policy instruments include interest rate, the money supply and exchange rate. It is sometimes
referred to a demand-side policy. The main policy is interest rate, and the base rate is set by an
independent organisation to the government. A higher interest rate is likely to decrease AD as it
discourages consumption and tends to lower firms investment as it costs more to borrow money. It
encourages foreigners to save in UK financial institutions. The rise in demands for GBP will increase the
interest rate, which makes exports expensive to others and imports cheap for the UK.
There is a chance that if interest rates rise, foreigners may be concerned with economic growth
prospects, and may put money elsewhere (reducing exchange rate).
An increase in the money supply is likely to increase AD. If more money is printed or if lending becomes
easier, people will have more money to spend with increases AD. If the government increases the
amount that banks can lend, interest rate falls. If the central bank wants to raise exchange rate, it can
increase interest rates and/or buy foreign currency. This is a deflationary monetary policy.
The Monetary Policy Committee (MPC) of the Bank of England sets interest rates with the main objective
of achieving the governments inflation target (2%). Because it is hard to consistently maintain the same
rate, there is a 1% margin either side of the target. The MPC has been instructed to support economicpolicy of the government, including objectives for employment and growth.

Factors considered by the MPC
GDP growth and spare capacity the MPC has to set an appropriate interest rate to promoteGDP growth in line with the increase in the economys productive potential.
Wages and labour costs the MPC may be concerned if wage inflation was too high as it couldlead to a rise in consumer prices due to demand-pull inflation.
Consumer and business confidence these provide useful indications of turning points in theeconomic cycle. For example, a dip in consumer optimism might herald a retrenchment of
spending which could lead to slower GDP growth and a weakening of inflationary pressure.
Trends in foreign exchange markets a weaker exchange rate may be a threat to inflationbecause it raises the prices of imported goods and services.
Supply side policies
Supply-side policies aim to increase aggregate supply. They can increase productive potential and canhelp prevent inflation, reduce structural and frictional unemployment and improve the countrys trade
position. They try to lower firms costs of production and increase productive capacity by increasing
efficiency of labour and product markets. Some supply-side policies are based on reducing government
intervention in the economy e.g. deregulation and privatisation. Others involve government intervention,
such as financed education and training, which could solve market failure.
Government investment in education and training, and government encouragement to firms to increase
their training should raise occupational mobility of labour and labour productivity. If output per worker
increases, AS shifts to the right and potential output rises. The government could encourage the
unemployed to undertake training, which develops skills, confidence and experience.

Assistance to new firms by offering grants or reducing corporation tax helps them break into established
markets. Lower direct tax can also increase AS because firms have a greater incentive. Firms gain more
funds and are able to invest it. If investment does increase, productivity capacity of the economy will rise.
Some economists believe that an income tax cut can stimulate workers to work longer, and some may be
more willing to re-enter work. This increases the size of the labour force. Disposable income will also behigher. However, more disposable income could encourage more leisure time, which results in people
working fewer hours.
National minimum wage could either encourage people to enter the labour force or reduce efficiency of
the labour market. There is a debate whether it is a supply-side policy.
Reduction in unemployment benefit (JSA) may force unemployed people to seek employment more
actively. This may result in people accepting lower wage rates. However, for those who are in cyclical
unemployment, they will get a reduced income, which reduces AD. This also increases income inequality,
which has social consequences.
Privatisation may lead to increased efficiency as they have to try and minimize costs and constantly
innovate. They are subject to discipline of the market. However, some economists say that government
ownership is beneficial where there is a high risk of market failure.
Deregulation makes it easier for competitors to enter the market and gives firms the belief that they have
greater freedom. Recently, the UK government has removed restrictions on competition with Royal Mail.
Government Policies on macroeconomic indicators
Policies on inflation
Controlling cost-push inflation will depend on the factors causing it. If excessive increases in wage rates
are causing the problem, then they could restrict wages by imposing a maximum increase e.g. 3% per
year. The government can cut public sector spending if this is happening in the public sector. The
introduction of an incomes policy, e.g. limiting wage increases of a certain percentage, can reduce
inflation without causing unemployment. However, it may crease inflexibility in labour markets. Firms
wanting to expand will be limited as to how much they can offer workers.
The government could cut firms costs by either cutting corporation tax or providing subsidies. This has
the similar effect of stimulating investment. The main problem with this is that firms may become reliant
on subsidies and not try and minimize costs.
Reducing demand pull inflation involves slowing growth of AD/decreasing AD. The government could
raise income tax. This will mean people have less disposable income, leading to a reduction in the
amount of disposable income. The main anti-inflation measure is changing interest rates. Increasing
interest rates will reduce AD by reducing consumption, investment and next exports while increasing
savings.
In the long run, governments are likely to reduce the possibility of inflation by increasing AS. If productive
potential increases with AD, the economy can grow without the price level rising as the increases in AS
and AD have opposing effects on price level, which cancel out.
Policies on economic growth

Short term GDP increases can occur due to increasing AD provided the economy has spare capacity. This
sort of increase can be increased by a fiscal or monetary policy. Some fiscal and monetary policy
instruments can increase both AD and AS. For example, a lower interest rate stimulates consumption and
investment (which increases AS). Increases in some government spending, e.g. education and research,
will also shift AS to the right.
In the long run, the only way to increase AS is if productive capacity of the economy increases. For this to
increase, the quantity and/or quality of resources must increase. Supply-side policies aim to achieve this.
For instance, measures that raise investment will boost AS. The extent of the AS increase depends on the
amount of additional investment and the efficient allocation of it.
To use capital efficiently, educated and healthy workers are required. Investing in human capital should
increase productive potential of the economy. The quality of investment, however, has an effect on the
extent of the increase. Workers need a range of skills in order to be productive, including literacy,
mathematical, ICT and interpersonal skills.
Governments tend to avoid AD increasing faster than trend growth because it can lead to inflation and
balance of payments problems. They also try to prevent AD rising slower than trend growth as this leads
to a negative output gap. This will result in stable growth.
Actual growth should match trend growth, and this has to be done over time.
Policies on balance of payments
Short run policies tend to concentrate on demand whereas long term measures focus on supply.
In the short term, the government may try to boost export revenue by many ways.
If a country feels that its currency is too strong, it may seek to weaken the exchange rate in order for
prices to be competitive on the international market. Selling its currency or reducing interest rate can
allow these changes to happen. This should only be done when demand for exports and imports is price
elastic as this will cause an increase in import revenue. This theory assumes ceteris paribus countries
may devalue the currency or increase import restrictions. Lowering the exchange rate in this way to
increase AD increases short run employment, but could lead to inflationary pressure.
To discourage spending in imports, the government may seek to reduce domestic spending by increasing
taxation and interest rates and cutting government spending. However, it could cause GDP to fall and
unemployment to rise.
Another strategy is to introduce tariffs (import taxes) and quotas on imports. Placing import taxes will
make international products less competitive, which should reduce imports. However, domestic firms
may lose the incentive to minimize costs due to the lower competition. Also, if other countries adopt a
similar policy in retaliation, then the UK runs the risk of losing out in export revenue. Membership of a
trading group (e.g. the EU) limits these actions.
If a trade deficit is because of low labour productivity, high inflation or a lack of quality competitiveness,
these measures will not provide solutions in the long term. In these circumstances, supply-side policies
should be implemented. This includes funding education and research to encourage innovation and
invention, and providing subsidies to infant industries in the belief that they have the potential to grow to
become internationally competitive.

A current account surplus may also be bad. The government may want to eliminate a surplus due to the
threat of inflation. To reduce a surplus, the government may seek to increase the value of the currency,
introduce policies that boost economic activity through inflationary means and/or reduce import
restrictions.
The effectiveness of government policies
Effectiveness of fiscal policy
Changes in government spending directly affect the G component in AD, while changes in tax affect C and
I components of AD by altering the disposable income of households and post-tax income of firms. AS can
also be increased.
However, changes in government spending and tax rates usually have a time lag time is required to
have an effect on the economy. It can also take time to recognise the need for a change in policy and to
gather the information on which to base the change. There is also time taken to draw up and implementnew tax codes and government spending plans. Government spending in some sectors is inflexible e.g.
healthcare and pensions. Also, it is politically and economically difficult to stop an investment project
once started.
For fiscal policy objectives to work, decisions have to be based upon accurate information. In addition to
this, households and firms may not react in the ways expected by the government. For example, a cut in
income and corporation tax may not result in higher consumption and investment as confidence may be
low.
Changes in fiscal policy mat have an adverse effect on other macroeconomic objectives. Rising income
taxes may discourage some from working, and a higher corporation tax may discourage investment. Arise in tax designed to reduce inflation may reduce AD too far and cause a fall in real GDP and cause
unemployment. Similarly, there is a risk that reflationary fiscal policy, while raising real GDP and
employment, may increase inflationary pressure and worsen a current account deficit. Fiscal policy
changes can offset changes in economic activity in other countries. If trading partners are experiencing
recession, AD may not rise much in the UK.
Effectiveness of monetary policy
This also depends on reliable information. Monetary policy instruments can be hard to control. In the
past, the UK and US have tried to control inflation by controlling the money supply, which was not easy.
Changing the interest rate is considered to be very successful. Some criticise the MPC for overestimating
inflation and keeping the interest rate too high, which limits economic growth. There is also a time lag to
see any impact on the economy. There is also the question of what extent the AD will rise in response to
the change in interest rate. If people are optimistic, a rising interest rate may not cause a reduction in
spending and investment. When interest rates are low, a further reduction is unlikely to be effective in
stimulating economic activity.
EU countries with the same currency have limited independent control over monetary policy. The
interest rate is set by the European central bank.

Changes in the monetary policy tend to affect more concentrated groups. An increased interest rate will
hit firms that export a lot because of higher costs and an unfavourable exchange rate. There are also
undesirable side effects an increased exchange rate can worsen balance of payments.
Effectiveness of supply side policies
These are selective. They are targeted at certain markets to raise efficiency. Increasing AS enables AD to
continue to rise over time without inflationary pressures. A higher resource quality makes domestic firms
more price and quality competitive, which will improve the countrys current account position.
However, this is not sufficient if there is a lack of AD. In this case, there would be a lot of spare capacity.
Many supply side policies, such as education spending, have a time lag. They can be expensive to
implement and there is no guarantee that they will work.
Conflicts between policy objectives
The objectives of economic growth and unemployment may benefit from expansionary demand side
policy measures. However, such measures make it hard to achieve low inflation and a good balance of
payments position. The MPC may face a conflict when setting interest rate. Raising interest rate to reduce
inflation may affect the exchange rate and balance of payments in a negative way.
Using a variety of policy instruments can help reduce conflict.
International Trade
International trade plays a massive part in the UK economy. UK firms are internationally competitive in
goods including aerospace engines and computer software. They are particularly strong in financial
services. The UK is not very competitive in industries that require heavy capital equipment or cheap
labour.
The majority of UK trade in goods and services is with EU countries. There has been a long-term shift in
our trade with EU since the UK joined the EEC in 1973. The share of UK trade with North American
countries has declined, but the United States remains the largest single export market accounting for 15%
of total UK exports. Trade with Asian countries has also increased, especially due to the number of
emerging economies, such as India, China and Malaysia. The growth of the Indian economy should help
ECONOMICS IN CONTEXT
The Peoples Bank of China (PBOC) usually uses changes in monetary supply. It does this by
changing the amount of funds available as well as placing direct limits on the amounts that banks
can lend.
PBOC favours changes in money supply because AD is interest inelastic. A rise in interest rate
does not significantly reduce investment because state-owned enterprises do not always
consider carefully the financial return on their purchase of capital goods.
The PBOC has been seeking to increase net exports by keeping the exchange rate low. It does
this by selling more of its currency (yuan) than by changing interest rate.

to boost exports to the sub-continent in the years to come, providing that UK businesses take advantage
of the export opportunities available there.
Trade liberalisation is the process when a country opens its markets up to international trade.
Advantages of increasing international trade
Countries can import goods that they do not specialise in. Firms can achieve economies of scale due to the larger market to buy raw materials and to sell
products to. The cheaper cost of production can be passed onto the consumers.
Consumers benefit from lower prices and higher quality products due to the increasedcompetition, as well as an increased number of products being available.
Trade enhances consumer choice, which drives innovation for new products and technology. It can raise living standards and reduce poverty levels.
Disadvantages of increasing international trade
International competition can result in structural unemployment due to occupational immobilityof labour (difficulty in moving from one type of job to another).
Increased domestic economic instability International trade cycles severely impact ondomestic firms as they become reliant on trade.
International markets are not fair countries with surplus products dump them on worldmarkets at a lower cost. Poorer countries with largely agricultural economies can develop debts
as the import prices are less than their exports revenue.
Developing countries/smaller firms (infant industries) can find it hard to establish they facea lot of competition from TNCs, which benefit from economies of scale.
Increased environmental problems can stem from increased trade.Protectionism is the economic policy of restricting trade to protect domestic industries from foreign
competition. This can be done by:
Quotas quantitative limits on the level of imports allowed in. Tariffs taxation on imports. This is the best known method of protection. It increases the cost
of importing goods, which promotes buying from domestic firms.
Voluntary Export Restraint Arrangementstwo countries agree to limit the number of exportsto each another over an agreed period of time.
Foreign exchange restrictions reducing the amount of foreign exchange made available forthose wishing to buy imported goods.
Embargoes banning exports/imports of a particular product and/or banning trade with anothercountry. For example, a country may ban arms exports to a country notorious for having a poor
human rights record.
Administrative barriers this could be introducing time-delaying customs procedures todiscourage imports (increases costs to import products). High quality standards and complex
restrictions may also be set with the intention of increasing costs of foreign firms seeking to
export their products into the country.
Export subsidies paying domestic firms to reduce their costs.

The main justification for protectionism is that infant industries can benefit from temporary protection
from foreign competition. However, these industries take a long time to develop, and temporary
measures often become permanent.
Arguments against Import Controls
Consumers are being taxed. EU measures often cause necessities to be most taxed. Thisregressive tax hurts the poorest consumers the most. Income inequality may increase.
Inefficiency increases protected firms have a lower incentive to lower production costs. Massive opportunity cost on imposing tarrifs employment could have been protected in other
ways. Protectionism policies are costly to implement.
Negative multiplier effect.
