Question 9.
According to classical theory of employment, how wage reduction solve the problem of unemployment diagramatically explain.
Answer:
According to Classical Economist, full employment condition can be achieved by cutting down the wage rate unemployment would be eliminated when wages are determined by the mechanism of Economy itself.

TN Board 12th Economics Important Questions Chapter 3 Theories of Employment and Income 1

Explanation of the Diagram:

  1. When the wage rate is OW, then employment is ON.
  2. As the wage rate is reduced to OW, then the employment has increased to ON.
  3. According to A.C. Pigou, this theory has a base for developing the solution of unemployment problem.
  4. The condition of unemployment cannot exist in normal economic conditions.
  5. This is because as the unemployment arises, wages would fall. In such a case, organisations would prefer to hire new employees, which would result in eliminating unemployment.
  6. “The law also assumes that there should neither be any intervention of government to regulate the rate of wages nor any role of trade unions.”
  7. According to Say’s law, the condition of unemployment exists only under some specific conditions. But this condition is momentary.

Question 10.

Question 12.
What do you mean by aggregate demand ? Mention its components.
Answer:
The aggregate demand is the amount of money which entrepreneurs expect to get by selling the output produced by the number, of labourers employed. So it is the expected income or revenue from the sale of output at different levels of employment.
Four components of aggregate demand

  1. Consumption demand
  2. Investment demand
  3. Government expenditure and
  4. Net export (Export – Import)

Question 13.
Explain about aggregate supply with the help of diagram.
Answer:
Aggregate supply is the value of total output of goods and services produced in a year. It is equal to the value of national product i.e., National income. It is the required amount of labourers and materials to produce the necessary output.
Aggregate supply = C + S + T + Rf = Aggregate income generated in the economy.

TN Board 12th Economics Important Questions Chapter 3 Theories of Employment and Income 3

Explanation of the Diagram:
Aggregate supply curves are drawn for the assumption of fixed money wages and variable wages.
Z curve is Linear and money wages are fixed, curve is non-linear, wage rate increases with employment. When full employment level of Nf is reached, it is impossible to increase output by employing more men. So aggregate supply curve becomes inelastic. (Vertical straight line)

Question 16.
Critically explain Say’s law of market.
Answer:
It is the core of classical theory of employment J.B. say enunciated the proposition that “ supply creates its own demand”. Hence there cannot be general over production or the problem of unemployment in the economy. According to say “ when goods are produced by firms in the economy, they pay reward to the factors of production. So each product produced in the economy creates demand equal to its value in the market”.

TN Board 12th Economics Important Questions Chapter 3 Theories of Employment and Income 5

Assumptions of the Say’s law of market:

  1. The price cannot be affected by single seller, buyer of commodity.
  2. There is full employment.
  3. No single buyer or seller of commodity or an input can affect price.
  4. Full employment.
  5. People are motivated by self interest and self-interest determines economic decisions.
  6. The laissez faire policy is essential for an automatic and self adjusting process of full employment equilibrium. Market forces determine everything right.
  7. There will be a perfect, competition in labour and product market.
  8. There is wage-price flexibility.
  9. Money acts only as a medium of exchange.
  10. Long – run analysis.
  11.  There is no possibility for over production or unemployment.

Implications of the Say’s law of market:

  1. Over production or unemployment is not possible.
  2. The unutilized resources are employed when factors accept rewards according to their productivity under full employment.
  3. No government intervention due to automatic price mechanism in the economy.
  4. Equality between savings and investment due to flexibility in interest.
  5. Money serves as a medium of exchange only because people will not hold idle money.

Criticisms of Say’s law:

  1. According to Keynes supply does not create its demand. It is not applicable where demand does not increase as much as production increases.
  2. Unemployment can be removed by increase in the rate of investment. Automatic adjustment process will not remove unemployment.
  3. Individuals hold money for unforeseen expenses and businessmen keep cash reserve for future activities. So money is not neutral.
  4. According to say there is no over production but according to Keynes over production is possible.
  5. Because of under employment in capitalist economies, Keynes regards full employment as a special case.
  6. The government intervention arises in the case of general over production and mass unemployment.

Question 17.
Narrate the equilibrium between ADF and ASF with diagram.
Answer:
Equilibrium between ADF and ASF could be explained with household and business sector (Two sector economy). It is assumed that consumption function is linear and planned investment is autonomous.
There are two approaches
(i) Aggregate demand – Aggregate supply approach
(ii) Saving – Investment approach
AD and AS approach is only taken to explain the determination of equilibrium level of income and employment.

TN Board 12th Economics Important Questions Chapter 3 Theories of Employment and Income 6

At the point ‘E’ the AD and AS reach equilibrium. The employment level is N0 at that point. At ON1, employment, the aggregate is N1, R1. But they are able to produce M1, N1.The expected level of profit is M1, R1.

At this level, entrepreneurs will employ more labourers. At the point E, the employment of labour will reach max and it will stop. At the level of beyond ON0 the aggregate demand curve is below the aggregate supply curve. But it will indicate loss to the producers. So they will not employ more than ON0 labour. Equilibrium level of employment need not be the full employment level (N1) the difference between N0 – Nf is the level of unemployment. Sa the concept of effective demand is significant in explaining the under employment equilibrium.
