In this figure 2 aggregate supply curves are drawn for the assumption of fixed money wages and variable wages.

Explanation
(i) Z Curve is linear (fixed money wages)
(ii) Z₁ curve is non-linear (wage rate increases with employment)
(iii) When full employment level of Nf is reached output cannot be increased by employing more men.
(iv) So aggregate supply curve becomes inelastic (Vertical straight line).
(v) In reality aggregate supply curve will be like Z₁ .
(vi) If prices are high and wages low, the producers will employ more labourers.
(vii) 4YAggregate supply is an important factor in determining the level of economic activity.

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.

Introduction
Under the Keynes theory of employment, a simple two sector economy consisting of the household sector and the business sector is taken to understand the equilibrium between ADF and ASF.
Explanation
1. AD and AS reach equilibrium at E. The employment level is N_o
2. At ON₁employment, the aggregate supply is N₁R₁. But the aggregate demand is M₁N₁.
3. The expected level of profit is M₁R₁.
4. To attain this level of profit, entrepreneurs will employ more labourers, till they reach point E i.e. ON_o.
5. Beyond ON_o, the aggregate demand curve is below the aggregate supply curve showing loss.
6. So they will never employ more than ON_o labour.
7. The equilibrium level of employment need not be the full employment level (N_o).
8. The difference between N_o - N₁ is the level of unemployment.
Conclusion
Thus the concept of effective demand becomes significant in explaining the under employment equilibrium.

Cyclical unemployment:
(i) During the downturn phase (recession and depression) of trade cycle, income and output fall leading to cyclical unemployment.
(ii) It is caused by deficiency of effective demand
Structural unemployment:
(i) Unemployment due to massive and deep rooted changes in economic structure leads to structural unemployment.
(ii) Lack of demand for the product or shift in demand to other products cause this type of unemployment.
(iii) (e.g.) rise in demand for mobile phones has adversely affected the demand for cameras, tape recorders
Disguised unemployment:
(i) It occurs in agriculture when more people are there than required. Even if some workers are withdrawn, production does not suffer.
Actual marginal productivity is zero, less or negative.
(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 (eg) ice cream industry, holiday resorts
(ii) Frictional unemployment (Temporary 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.
