Introduction
According to J. B. Say "Supply creates its own demand"
Explanation
A person receives his income from production which is spent on the purchase of goods and services produced by others. For the economy as a whole, therefore, total production equals total income.
Criticisms
(i) According to Keynes, supply does not. create its demand. It is not applicable where demand does not increase as much as production increases.
(ii) Automatic adjustment process will not remove unemployment. Unemployment can be removed by increase in the rate of investment.
(iii) Money is not neutral. Individuals hold money for unforeseen contingencies, businessmen keep cash reserve for future activities.
(iv) Say's law is supply creates its own demand and there is no over production. Keynes said that over production is possible
(v) Keynes regards full employment as a special case because there is underemployment in capitalist economies.
(vi) State intervention is needed when there is over production and mass unemployment.

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 Even if some workers are withdrawn, production does not suffer.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.
