Withdrawals
• Net saving(S):Saving is income that households choose not to spend but no to put aside for the future.
• Net taxes(T):When people pay taxes(to either central or local government),this represents a withdrawal of money from the inner flow in much the same way as saving, only in this case people have no choice.
Transfer payments: When people receive benefits from the government ,such as working tax credit ,child benefit and pensions, the money flows the other way.
• Import expenditure(M):Not all consumption is of home-produced goods. Households spend some of their incomes on imported goods and services.

Injections
Investment(I):This is the flow of money that firms spend which they obtain from various financial institutions-either past savings or loans, or through a new issue of shares.
Government expenditure(G):When the government spends money on goods and services produced by firms.
Export expenditure(X):Money flows into the circular flow from abroad when residents abroad buy our exports of goods and services.

The Business Cycle
The four ‘phases’ of the business cycle:
The upturn: In this phase, a stagnant economy begins to recover and growth in GDP resumes. Business confidence begins to grow.
The expansion: During this phase there is rapid economic growth, the economy is booming. Rapid growth in consumers demand creates a climate of business confidence and firms respond by producing more.
The peaking-out: During this phase, growth slows down or even ceases. The slowdown, recession or slump: During this phase, there is little to growth or even a decline in output.

Unemployment and the labour market
Causes of unemployment:
• Equilibrium unemployment:
The difference between those who would like employment at the current wage rate and those willing and able to take the job.
• Disequilibrium unemployment:
The aggregate supply of labour must exceed the aggregate demand
There must be a ‘stickiness’ in wages. In other words, the wage rate must not immediately fall.

• Frictional (search) unemployment: Occurs when people leave their jobs, either voluntarily or because they are sacked or made redundant, and are then unemployed for a period of time while they are looking for a new job.
• Structural unemployment
