Macro Flashcards
The government has four main macroeconomic objectives.
These aim to provide macro stability. Economic growth, Minimising unemployment, Price stability, Stable balance of payments on current account. Additionally, the government might have the following macroeconomic objectives: Balanced government budget, Greater income equality
The performance of an economy can be measured with the following data:
Real GDP, Real GDP per capita, Consumer Prices Index and Retail Prices Index (CPI/RPI), Measures of unemployment, Measures of productivity, Balance of payments on current account
National income can also be measured by:
Gross National Product (GNP), Gross National Income (GNI)
The circular flow of income
Firms and households interact and exchange resources in an economy.
Households supply firms with the factors of production, such as labour and capital,
and in return, they receive wages and dividends.
Firms supply goods and services to households. Consumers pay firms for these.
This spending and income circulates around the economy in the circular flow of
income, which is represented in the diagram above.
Saving income removes it from the circular flow. This is a withdrawal of income.
Taxes are also a withdrawal of income, whilst government spending on public and
merit goods, and welfare payments, are injections into the economy.
International trade is also included in the circular flow of income. Exports are an
injection into the economy, since goods and services are sold to foreign countries
and revenue in earned from the sale. Imports are a withdrawal from the economy,
since money leaves the country when goods and services are bought from abroad.
Full employment income is the total output of an economy when unemployment is
minimised or is at the government target. This accounts for frictional
unemployment.
The effect of changes in injections and withdrawals on national income
An injection into the circular flow of income is money which enters the economy.
This is in the form of government spending, investment and exports.
A withdrawal from the circular flow of income is money which leaves the economy.
This can be from taxes, saving and imports.
The economy reaches a state of equilibrium when the rate of withdrawals = the rate
of injections.
The amount of savings in an economy is equal to the amount of investment. In the
UK, there is a traditionally low savings rate, especially during periods of high
economic growth, and this means that the rate of investment is also low. In Japan
there is a high savings rate and with this comes a high level of investment.
If there are net injections into the economy, there will be an expansion of national
output.
If there are net withdrawals from the economy, there will be a contraction of
production, so output decreases.
The downward slope of the AD curve can be explained by:
. Higher prices lead to a fall in the value of real incomes, so goods and services
become less affordable in real terms.
. If there was high inflation in the UK so that the average price level was high,
foreign goods would seem relatively cheaper. Therefore, there would be
more imports, so the deficit on the current account might increase, and AD
would fall.
. High inflation generally means the interest rates will be higher. This will
discourage spending, since saving becomes more attractive and borrowing
becomes expensive.
Shifting the AD curve
. A rise in AD is shown by a shift to the left in the demand curve (AD1 AD2). This
rise in economic growth occurs when:
. Consumers and firms have higher confidence levels, so they invest and spend
more, because they feel as though they will get a higher return on them. This
is affected by anticipated income and inflation.
. If the Monetary Policy Committee lowers interest rates, it is cheaper to
borrow and reduces the incentive to save, so spending and investment
increase. However, there are time lags between the change in interest rates
and the rise in AD, so this is not suitable if a rise in AD is needed immediately.
. Lower taxes mean consumers have more disposable income, so AD rises.
. An increase in government spending will boost AD.
. Depreciation in a currency means M is more expensive, and X is cheaper, so
AD increases. A decline in economic growth in one of the UK’s export markets
means there will be a fall in X, so AD falls.
. In the UK, most people own their houses. This means that a rise in the price
of houses makes people feel wealthier, so they are likely to spend more. This
is the wealth effect.
. If credit is more available, then spending and investment might increase.
Recently, since the financial crisis of 2008, banks have been less willing to
lend due to the risks associated with lending.
Shifting the AS curve:
The SRAS curve shifts when there are changes in the conditions of supply.
- The cost of employment might change, e.g. wages, taxes, labour
productivity - The cost of other inputs e.g. raw materials, commodity prices, the
exchange rate if products are imported - Government regulation or intervention, such as environmental laws
and taxes, and business regulation. Business regulation is sometimes
called ‘red tape’.
Aggregate demand
Aggregate demand is the total demand in the economy. It measures spending on goods and
services by consumers, firms, the government and overseas consumers and firms.
It is made up of the following components, which make up the equation: C + I + G +(X-M)
Influences on consumer spending:
Interest rates
. If the Monetary Policy Committee lowers interest rates, it is cheaper to
borrow and reduces the incentive to save, so spending and investment
increase. However, there are time lags between the change in interest rates
and the rise in AD, so this is not suitable if a rise in AD is needed immediately.
Lower interest rates also lower the cost of debt, such as mortgages. This
increases the effective disposable income of households.
Consumer confidence
. Consumers and firms have higher confidence levels, so they invest and spend
more, because they feel as though they will get a higher return on them. This
is affected by anticipated income and inflation.
. If consumers fear unemployment or higher taxes, consumers may feel less
confident about the economy, so they are likely to spend less and save more.
This delays large purchases, such as houses or cars.
. Wage growth. Higher wages are the most significant factor in encouraging consumer spending.
. Inflation. Inflation can be influential in determining spending. If inflation is greater than nominal wage growth, then consumers will see a fall in disposable income.
. Deflation – periods of deflation (falling prices) can also have a negative impact on consumer spending. If prices are falling, consumers may feel that prices will be cheaper in the future and therefore, they delay purchasing goods – hoping they will be cheaper. Deflation can also cause a rise in the real value of debt, squeezing incomes.
. House prices – Housing is the biggest form of wealth. When house prices are rising people are more confident to spend and they can also reportage their houses. Rising house prices cause a wealth effect – with higher prices encouraging spending.
The accelerator process:
. The accelerator effect suggests that the level of investment in an economy is
related to the change in GDP. A higher rate of economic growth causes more
investment.
. If the rate of economic growth is slowing, but the economy is still growing,
the level of investment might fall.
. The level of investment is more volatile than the rate of economic growth.
Influences on government expenditure:
The trade cycle, Fiscal policy, Exports minus imports
The trade cycle
The trade cycle
. This is another term for the business cycle, which refers to the stage of
economic growth that the economy is in.
. The economy goes through periods of booms and busts. o Real output increases when there are periods of economic growth. This is the
recovery stage.
. The boom is when economic growth is fast, and it could be inflationary or
unsustainable.
. During recessions, there real output in the economy falls, and there is negative
economic growth.
. During recessions, governments might increase spending to try and stimulate the
economy. This could involve spending on welfare payments to help people who have
lost their jobs, or cutting taxes.
. This will increase the government deficit, and they may have to finance this.
. During periods of economic growth, governments may receive more tax revenue
since consumers will be spending more and earning more. They may decide to spend
less, since the economy does not need stimulating, and fewer people will be
claiming benefits.
Fiscal policy
. Governments use fiscal policy to influence the economy. It involves changing
government spending and taxation.
. Governments might spend on public goods and merit goods, as well as
welfare payments.
. Fiscal policy is a demand-side policy, so it works by influencing the level or
composition of AD.
. Discretionary fiscal policy is a policy which is implemented through one-off
policy changes.
. Automatic stabilisers are policies which offset fluctuations in the economy.
These include transfer payments and taxes. They are triggered without
government intervention.
. The government might use expansionary fiscal policy during periods of economic decline. This involves increasing spending on transfer payments or on boosting AD, or by reducing taxes.
. During periods of economic growth, governments might use contractionary
fiscal policy by decreasing expenditure on purchases and transfer payments.
Additionally, tax rates might increase. This reduces the size of the
government budget deficit.
