A government’s budget
is an annual statement of projected outlays and
receipts during the next year
Government’s budget balance
Budget balance = Receipts – Outlays
budget surplus: receipts > outlays
budget deficit: receipts < outlays
balanced budget: receipts = outlays
Four sources of receipts
- Taxes on income and wealth
- Taxes on expenditure
- National Insurance contributions
- Other receipts and royalties
Three categories of outlays
- Expenditures on goods and
services - Transfer payments
- Debt interest

The effects of the income tax
- The income tax decreases the supply of labour and create a new labour market equilibrium - The before-tax wage rate rises, the after-tax wage rate falls and employment decreases
The Laffer curve
- The relationship between the tax rate and the amount of tax revenue collected - a higher tax rate rises pre-tax wage rate but reduce labour hours so it does not always bring in more revenue
Autononmous spending
- Autonomous expenditure is the sum of investment, government
expenditure, and exports, which does not vary with GDP
Aggregate expenditure
𝐴𝐸 = 𝐶 + 𝐼 + 𝐺 + 𝑁𝑋
• where AE is aggregate expenditure, C is consumption, I is investment, G is
government spending, NX is net exports.
Fiscal stimulus
is the use of fiscal policy to increase
production and employment.
ways to stimulate economy fiscally
an increase in government outlays or a decrease in government receipts can stimulate production and jobs - an increase in expenditure on goods and services directly increases aggregate expenditure - lower tax also strengthen the incentives to work and invest
Monetary policy objectives
The Bank of England Act of 1998 sets out the objectives of UK monetary
policy:
To maintain price stability
subject to that, to support economic growth and employment.
The act also establish the Monetary Policy Committee
is the committee of nine members in the Bank that has the responsibility for
setting monetary policy.
monetary policy: Price stability objective
The operational definition of price stability since the beginning of 2004
has been:
An inflation target of 2 per cent a year as measured by the 12-month increase in
the CPI.
target range is from 1 per cent to 3 per cent.
Government economic policy objectives
• The government’s economic policy objectives are to achieve high and
stable levels of economic growth and employment.
Price stability is a major contributor to achieving the other goals of
government economic policy.
price stability provides the best available environment for households and
firms to make the saving and investment decisions that bring economic growth
Rationale for an inflation target
First, the Bank of England’s policy actions are more clearly understood by
financial sector.
A clear understanding leads to fewer surprises and mistakes on the market
rates
i.e., rises interest rate when inflation is high
Second, the target provides an anchor for expectations about future
inflation.
firmly held (and correct) inflation expectation help individuals and firms to
make better economic decisions, which in turn help to achieve a stable
economic growth.
The monetary policy instrument
The Bank of England choose quantity of reserve supplied Bank Rate (i.e., price) - The Bank’s choice is Bank Rate, which is the target for the repo rate (the overnight interest rate at which banks borrow reserves from central bank) - The market for bank reserves. • banks’ demand for reserves is a derived demand • repo rate is closely related to market interest rates • the lower the repo rate, the higher the demand for money, thus the higher banks’ demand for reserve
The Bank of England can use open
market operation
to control the quantity of reserve supplied in the market, and thus move the repo rate to its target level, i.e., Bank Rate. • to decrease reserves in the market the Bank conducts an open market sales (sell bonds and buy reserves) • to increase reserves in the market the Bank conducts an open market purchases (buy bonds and sell reserves)
Money policy transmission: bank lowers bank rate
- bank of england lowers bank repo rate
- other short term interest rates fall and the exchange rate
- the quantity of money and supply of loanable funds increase
- long term interest rate falls
- consumption expenditure, investment and met exports increase
- aggregate demand increases
- real gdp growth and the inflation rate increae
Money policy transmission: bank raises bank rate
- bank of england raises bank rate
- other short term interest rates rise and the exchange rate rises
- quantity of money and supply of loanable funds decrease
- long term interest rates rise
- consumption expenditure, investment and net exports decrease
- aggregate demand decreases
- real gdp growth and the inflation rate decreases.
Real GDP
is the value of final goods and
services produced in a given year
at the prices of a reference year
Potential GDP
is the quantity of real GDP at full employment – when the economy’s labour, capital, land and entrepreneurial ability are fully used. • data is not collectable
Economic growth
is the growth rate of potential GDP that measures the pace of movement
of production possibilities
Real GDP per person
the standard of living depends on real GDP per capita
