Question 42.
(a) Explain the law of demand with a diagram.
Answer:
Definition:
According to Alfred Marshall, the Law of Demand said as “the quantity demanded increases with a fall in price and diminishes with a rise in price”.

Assumptions of Law of Demand:

  1. The income of the consumer remain constant.
  2. The taste, habit and preference of the consumer remain the same.
  3. The prices of other related goods should not change.
  4. There should be no substitutes for the commodity in study.
Price Quantity
Demanded
5 1
4 2
3 3
2 4
1 5

Tamil Nadu 11th Economics Previous Year Question Paper March 2019 English Medium 6

Explanation:

  1. Quantity demanded and Y axis represents the price of the commodity.
  2. DD is the demand curve, which has a negative slope.
  3. Slope downward from left to right which indicates that when price falls, the demand expands and when price rises, the demand contracts.

Conclusion:
Therefore, the law of demand states that there is an inverse relationship between the price and the quantity demanded of a commodity.

(b) Illustrate the Ricardian theory of Rent.
Answer:
Definition:
According to Ricardo, “Rent is the that portion of the produce of the earth which is paid to the landlord for the use of the original and indestructible powers of the soil”.

Assumptions:

  1. Land differs in fertility.
  2. The law of diminishing returns operates in agriculture.
  3. Rent depends upon fertility and location of land.
  4. Theory assumes perfect competition.

Schedule of Ricardian Theory of Rent:

Grades of Lands Production (in bags) Surplus (i.e., Rent in bags)
A 40 40 – 20 = 20
B 30 30 – 20 = 10
C 20 20 – 20 = 0

Tamil Nadu 11th Economics Previous Year Question Paper March 2019 English Medium 7

Explanation:

  1. In diagram, X axis represents various grades of land and Y axis represents yield per acre (in bags).
  2. 0A, AB and BC are the ‘A’ Grade, ‘B’ grade and ‘C’ grade lands respectively.
  3. The application of equal amount of labour and capital on each of them gives a yield represented by the rectangles standing just about the respective bases.
  4. The ‘C’ grade land is the ‘no-rent land’ “A” and “B” grade lands are “intra – marginal lands”.

Question 43.
(a) Describe the properties of Iso – quants with the help of diagrams.
Answer:
Properties of Iso-quant Curve:
Tamil Nadu 11th Economics Previous Year Question Paper March 2019 English Medium 8
1. The iso-quant curve has negative slope.
It slopes downwards from left to right indicating that the factors are substitutable. If more of one factor is used, less of the other factor is needed for producing the same level of output. In the diagram combination A refers to more of capital K5 and less of labour L2. As the producer moves to B, C, and D, more labour and less capital are used.

2. Convex to the origin.
This explains the concept of diminishing Marginal Rate of Technical Substitution (MRTSLK). For example, the capital substituted by 1 unit of labour goes on decreasing when moved from top to bottom. If so, it is called diminishing MRTS. Constant MRTS (straight line) and increasing MRTS (concave) are also possible. It depends on the nature of iso-quant curve.

This means that factors of production are substitutable to each other. The capital substituted per unit of labour goes on decreasing when the iso-quant is convex to the origin.

Marginal Rate of technical substitution
Tamil Nadu 11th Economics Previous Year Question Paper March 2019 English Medium 9

3. Non inter-section of Iso-quant curves.
For instance, point A lie on the isoquants IQ1 and IQ2. But the point C shows a higher output and the point B shows a lower level of output IQ1.
If C = A, B = A, then C = B. But C > B which is illogical.
Tamil Nadu 11th Economics Previous Year Question Paper March 2019 English Medium 10

4. An upper iso-quant curve represents a higher level of output.
Higher IQs show higher outputs and lower IQs show lower outputs, for upper iso-quant curve implies the use of more factors than the lower isoquant curve.

The arrow in the figure shows an increase in the output with a right and upward shift of an iso-quant curve.
Tamil Nadu 11th Economics Previous Year Question Paper March 2019 English Medium 11

5. Iso-quant curve does not touch either X axis or Y axis.
No iso-quant curve touches the X axis or Y axis because in IQ1 only capital is used, and in IQ2 only labour is used.

Question 44.
(a) Bring out the relationship between AR and MR curves under various price conditions.
Answer:
If a firm is able to sell additional units at the same price then AR and MR will be constant and equal. If the firm is able to sell additional units only by reducing the price, then both AR and MR will fall and be different.

Constant AR and MR (at Fixed Price):
When price remains constant or fixed, the MR will be also constant and will coincide with AR. Under perfect competition as the price is uniform and fixed, AR is equal to MR and their shape will be a straight line horizontal to X axis. The AR and MR Schedule under constant price is given in the below table and in the diagram.
Tamil Nadu 11th Economics Previous Year Question Paper March 2019 English Medium 14

Declining AR and MR (at Declining Price):
When a firm sells large quantities at lower prices both AR and MR will fall but the fall in MR will be more steeper than the fall in the AR.

It is to be noted that MR will be lower than AR. Both AR and MR will be sloping downwards straight from left to right. The MR curve divides the distance between AR Curve and Y axis into two equal parts. The decline in AR need not be a straight line or linear. If the prices are declining with the increase in quantity sold, the AR can be non-linear, taking a shape of concave or convex to the origin.

(b) If the demand function is P = 35 – 2x – x2 and the demand x0 is 3, what will be the consumer’s surplus?
Answer:
Given demand function,
P = 35 – 2x – x2 For x = 3
P = 35 – 2(3) – 32
= 35 – 6 – 9.
P = 20 Therefore,
CS = (Area of the curve below the demand curve from 0 to 3) – Area of the rectangle (20 x – = 60)

= 105 – 9 – 9 – 60 = 27 Units

Question 45.
(a) Explain the features of Oligopoly.
Answer:

  • Few large firms: Very few big firms own the major control of the whole market by producing major portion of the market demand.
  • Interdependence among firms: The price and quality decisions of a particular firm are dependent on the price and quality decisions of the rival firms.
  • Group behaviour: The firms under oligopoly relalise the importance of mutual cooperation.
