(i) In the Keynesian model, output is determined mainly by aggregate demand.
(ii) The aggregate demand is the amount of money which entrepreneurs expect to get by selling the output produced by the labourers employed.
(iii) Aggregate demand (spending) is the amount that households, firms, the governments and the foreign purchasers would like to spend on domestic output
Aggregate demand has four components:
1. Consumption demand (C)
2. Investment demand (I)
3. Government expenditure (G)
Net Export ( export - import) (X - M)
AD = C + I + G + (X - M)

(i) There is no possibility for over production or unemployment.
(ii) If there exist unutilized resources, it is profitable to employ them up to full employment.
(iii) There is automatic price mechanism, so no need for government intervention
(iv) Interest flexibility brings about equality between saving and investment.
(v) Money acts as the medium of exchange.

(i) Classical unemployment occurs when real wages are kept above the market clearing wage rate, leading to a surplus of labour supplied.
(ii) Classical unemployment is also called real wage unemployment.
(iii) Unemployment occurs when the worker is willing to accept (Real Wages)(RW) is in excess of those an employer is willing to pay (Market Clearing Wage)(MCW).
(iv) Real wage may be above the equilibrium level because of minimum wage policies or union bargaining.
(v) classical unemployment of Q₁-Q₂ can be solved by a wage cut.
(vi) If wages are allowed to fall to the market clearing level, unemployment is solved

(i) Seasonal unemployment
1. In agriculture and agro based industries like sugar production activities are carried out only in some seasons.
2. These industries offer employment only during that season in a year.
3. People remain unemployed during the off season.
4. Seasonal unemployment takes place from demand side also (e.g.) ice cream industry, holiday resorts.
(ii) Frictional unemployment
1. It arises due to imbalance between supply of labour and demand for labour.
2. It is because of immobility of labour, lack of necessary skills, break down of machinery, shortage of raw materials
3. The persons who lose jobs and in search of jobs also come under frictional unemployment
(iii) Educated unemployment
1. Educated people are underemployed or unemployed when qualification does not match the job.
2. Faulty education system, lack of employable skills, mass student turnout and preference for white collar jobs are highly responsible for educated unemployment.
