Part – B

Answer the following questions in one or two sentences

Question 21.
Classify the factors of production.
Answer:

1. Land: In Economics, land means all gifts of Nature owned and controlled by human beings which yield an income.
2. Labour: Labour means manual labour or unskilled work.
3. Capital: “Capital consists of all kinds of wealth other than free gifts of nature, which yield income”.
4. Bohm – Bawerk defines it as ‘a produced means of production’.
5. Organization: The man behind organizing the business is called as ‘Organizer’ or ‘Entrepreneur’.

Question 22.
Define labour?
Answer:

1. Labour is the active factor of production.
2. In common parlance, labour means manual labour or unskilled work. But in Economics the term ‘labour’ has a wider meaning.
3. It refers to any work undertaken for securing an income or reward. Such work may be manual or intellectual. For example, the work done by an agricultural worker or a cook, or rickshaw puller, or a mason is manual.
4. The work of a doctor or teacher or engineer is intellectual.
5. In short, labour in economics refers to any type of work performed by a labourer for earning an income.

Question 23.
State the production function.
Answer:

1. Production function refers to the relationship among units of the factors of production [inputs] and the resultant quantity of a good produced [out put].
2. According to George J. Stigler, the Production function is the relationship between inputs of productive services per unit of time and outputs of product per unit of time.

Question 24.
Define the Marginal Product of a factor?
Answer:
It is the addition or the increment made to the total product when one more unit of the variable input is employed. In other words, it is the ratio of the change in the total product to the change in the units of the input. It is expressed as
MP = ∆TP/∆N
Where MP = Marginal Product
∆TP = Change in total product
∆N = Change in units of input
It is also expressed as MP = TP [n] – TP [n-1]
MP = Marginal product
TP [n] = Total product of employing nth unit of a factor.
TP [n – 1] = Total product of employing the previous unit of a factor, that is, [n – 1]^th unit of a factor.

Question 25.
What is the Iso-cost line?
Answer:

1. The isocost line is an important component in analyzing the producer’s behaviour.
2. The isocost line illustrates all the possible combinations of two factors that can be used at given costs and for a given producer’s budget.
3. Simply stated, an isocost line represents different combinations of inputs which show the same amount of cost.
4. The isocost line gives information on factor prices and the financial resources of the firm.
5. It is otherwise called as “iso – price line” or “iso – income line” or “iso – expenditure line” or “total outlay curve”.

Question 26.
What are the conditions for the producer’s equilibrium?
Answer:
The two conditions that are to be fulfilled for the attainment of producer equilibrium are:

1. The isocost line must be tangent to the isoquant curve.
2. At the point of tangency, the isoquant curve must be convex to the origin or MRTSLk must be declining.

Question 27.
What are the reasons for the upward-sloping supply curve?
Answer:
A supply curve represents the data given in the supply schedule. As the price of the commodity increases, the quantum supplied of the commodity also increases. Thus the supply curve has a positive slope from left to right.

Part – C

Answer the following questions in One Paragraph

Question 28.
What are the characteristics of land?
Answer:

1. Land is a primary factor of production
2. Land is a passive factor of production
3. Land is the free gift of nature
4. Land has no cost of production
5. Land is fixed in supply. It is inelastic in supply
6. Land is permanent
7. Land is immovable
8. Land is heterogeneous as it differs infertility
9. Land has alternative uses
10. Land is subject to Law of Diminishing Returns.

Question 29.
What are the factors governing the elasticity of supply?
Answer:
1. Nature of the commodity:
Durable goods can be stored for a long time. So, the producers can wait until they get a high price. Once they get a higher price, a larger supply is possible. The elasticity of the supply of durable goods is high. But perishables are to be sold immediately. So perishables have a low elasticity of supply.

2. Cost of production:
When production is subject to either constant or increasing returns, additional production and therefore increased supply is possible. So elasticity of supply is greater. Under diminishing returns, an increase in output leads to high cost. So elasticity of supply is less.

3. Technical condition:
In large scale production with huge capital investment, supply cannot be adjusted easily. So elasticity of supply is lesser. Where capital equipment is less and technology simple, the supply is more elastic.

4. Time factor:
During a very short period when supply cannot be adjusted, the elasticity of demand is very low. In a short period, variable factors can be added and so supply can be adjusted to some extent. So elasticity of supply is more. In a long period, even the fixed factors can be added, and hence the supply is highly elastic.

Question 30.
What are the functions of entrepreneurs?
Answer:
Functions of an Entrepreneur:

• Initiation: An organizer is the initiator of the business, by considering the situation and availability of resources and planning the entire process of business of production.
• Innovation: A successful entrepreneur is always an innovator. He introduces new methods in the production process.
• Coordination: An organizer applies a particular combination of the factor of production to start and run the business or production.
• Control, Direction, and Supervision: An organizer controls so that nothing prevents the organization from achieving its goal. He directs the factors to get better results and supervises for the efficient functioning of all the factors involved in the process of production.
• Risk-taking and uncertainty-bearing: There are risk-taking and uncertainty-bearing obstacles. Risks may be insured but uncertainties cannot be insured. They reduce the profit.

Question 31.
State and explain the elasticity of supply.
Answer:
The elasticity of supply may be defined as the degree of responsiveness of change in supply to change in price on the part of sellers.
Mathematically:

Q – Supply, p – price, ∆ – change.

Question 32.
Bring out the Relationship among Total, Average and Marginal Products.
Answer:

Question 33.
Illustrate the concept of Producer’s Equilibrium.
Answer:
Producer equilibrium is the situation where the producer maximizes his output. It is also known as the optimum combination of the factors of production.
(Eg.) Maximum output at minimum cost.
Producer attains equilibrium where the Iso-cost line is tangent to the Iso-quant.

In the figure profit of the firm is maximised at the point of equilibrium.
At the point of equilibrium slope of the Iso-cost line = Slope of Iso-product curve At point E, the firm employs OM units of labour and ON units of capital which is the least cost combination.

Question 34.
State the Cobb – Douglas Production Function?
Answer:
The Cobb – Douglas Production Function was developed by Charles W. Cobb and Paul H. Douglas, based on their empirical study of the American manufacturing industry. It is a linear homogeneous production function which implies that the factors of production can be substituted for one another up to a certain extent only.

The Cobb – Douglas production function can be expressed as follows.
Q = AL²K²
Where, Q = output; A = positive constant;
K = capital;
L = Labor α and β are positive fractions showing, the elasticity coefficients of outputs for the inputs labor and capital, respectively.
P = (1 – a) since a + p = 1. denoting constant returns to scale.
Factor intensity can be measured by the ratio β / α.

The sum of α + β shows the returns to scale.

1. (α + β) = 1, constant returns to scale.
2. (α + β) < 1, diminishing returns to scale.
3. (α + β) >1, increasing returns to scale.

• The production function explains that with the proportionate increase in the factors, the output also increases in the same proportion.
• Cobb – Douglas production function implies constant returns to scale.
• Cobb – Douglas Production Function is a specific standard equation applied to describe how much output can be made with capital and labor inputs.

Answer the following questions in about a page

Question 35.
Examine the Law of Variable Proportions with the help of a diagram.
Answer:
According to G. Stigler, “As equal increments of one input are added, the inputs of other productive services being held constant, beyond a certain point the resulting increments of the product will decrease (ie) the marginal product will diminish”.
Assumptions:

1. Only one factor is variable.
2. All units of the variable factor are homogeneous
3. The product is measured in physical units.
4. There is no change in the state of technology and the price of the product.

Stage of production:

Units of variable factor (labour) are employed along with other fixed factors. There are three stages of production.

Stage I:

1. In the first stage MP_L increases upto third labourer and is higher than the average product.
2. So that total produt is increasing at an increasing rate.

Stage II:

1. MP_L decreases up to the sixth unit of labour where MP_L curve intersects the x-axis.
2. The fourth unit of labour MP_L = AP_L
3. After this, MP_L curve is lower than the AP_L. TP_L increases at a decreasing rate.

Stage III:

1. The seventh unit of labour is marked by negative MP_L the AP_L continues to fall but positive.
2. TP_L declines with the employment of more units of labour.

Question 36.
List out the properties of Iso-quants with the help of diagrams.
Answer:
Iso-quant:
“An Iso-quant is a curve showing all possible combinations of inputs physically capable of producing a given level of output” – Ferguson.

Properties of Iso-quant curve:
1. The Iso-quant curve has a negative slope:

1. It slopes downwards from left to right indicating that the factors are substitutable.
2. In the diagram combination, A refers to more of capital K₅ and less of labour L₂
3. As the producer moves to B, C, and D more labour and less capital are used.

2. Convex to the origin:

1. In production, the capital substituted by 1 unit of labour goes on decreasing. It is called the diminishing marginal rate of technical substitution.
2. If the marginal rate of technical substitution diminishes the Iso-quants will be convex to the origin.
3. Constant MRTS (straight line) and increasing MRTS (concave).

3. Non-inter-section of Iso-Quant curves:

1. Point A lie on the Iso-quants IQ₁ and IQ₂
2. But the point C shows a higher output and point B shows a lower level of output IQ₁
3. If C = A, B = A, then C – B. But C > B which is illogical.
   

4. An upper Iso-quant curve represents a higher level of output:

1. Higher IQ_s show higher outputs and lower IQ_s show lower output.
2. The arrow in the figure shows an increase in the output with a right and upward shift of an Iso-quant curve.

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 IQ, the only capital is used and in IQ₂ only labour is used.

Question 37.
Elucidate the Laws of Returns to Scale. Illustrate.
Answer:
Laws of Returns To Scale: In the long – run, there is no fixed factor; all factors are variable.
The laws of returns to scale explain the relationship between output and the scale of inputs in the long – run when all the inputs are increased in the same proportion.

Assumptions:
Laws of Returns to Scale are based on the following assumptions.

1. All the factors of production, [such as land, labour, and capital] are variable but the organization is fixed.
2. There is no change in technology.
3. There is perfect competition in the market.
4. Outputs or returns are measured in physical quantities.

Three Phases of Returns to Scale:

1. Increasing Returns to Scale: In this case, if all inputs are increased by one percent, output increase by more than one percent.
2. Constant Returns to Scale: In this case, if all inputs are increased by one percent, output increases exactly by one percent.
3. Diminishing Returns to Scale: In this case, if all inputs are increased by one percent, output increases by less than one percent.

In the diagram, the movement from point a to point b represents increasing returns to scale. Between these two points, input has doubled but the output was tripled.

The law of constant returns is implied by the movement from point b to point c. Between these two points inputs have doubled and output also has doubled.

Decreasing returns to scale are denoted by the movement from the point c to point d since doubling the factors from 4 units to 8 units produce less than the increase in inputs, that is by only 33.33%.

Question 38.
Explain the internal and external economies of scale.
Answer:
The scale of production is an important factor affecting production. Every producer wishes to reduce the costs of production by using economies of scale.
Marshall classified economies into two.
1. Internal economies of scale: Internal economies refer to the reduction in the cost of production of the commodity. They are of various types.

• Technical economies: When the size and capital of the firm is large, up-to-date technologies can be used to improve the productivity of the firm. Here research and development strategies can be applied easily.
• Financial economies: Big firms can float shares in the market for capital expansion, while small firms cannot do so.
• Managerial economies: Large scale production facilitates specialization and delegation.
• Labour economies: Large scale production implies greater and minute division of labour. This leads to specialization which enhances the quality. This increases the productivity of the firm.
• Marketing economies: The producers can both buy raw-materials in bulk at a cheaper cost and can take the products to distant markets.
• Economies of survival: Product diversification is possible and it reduces the risk in production. Even if the market for one product collapses, the market for other commodities offsets it.

Question 39.
External economies of scale:
Answer:
External economies of scale refer to changes in any factor outside the firm or industry causing an improvement in the production process.
Important external economies are:

1. Increased transport facilities.
2. Banking facilities
3. Development of townships
4. Development of information and communication

Answer the following questions in about a page

Question 1.
What are the characteristics of labour?
Answer:

1. Labour is the animate factor of production.
2. Labour is an active factor of production.
3. Labour implies several types: It may be manual [farmer] or intellectual [teacher, lawyer, etc]
4. Labour is perishable.
5. Labour is inseparable from the labourer.
6. Labour is less mobile between places and occupations.
7. Labour is a means as well as an end. It is both the cause of production and the consumer of the product.
8. Labour units are heterogeneous.
9. Labour differs inability.
10. Labour – supply determines its reward [wage]
11. Labour has weak bargaining power.

Question 2.
Explain the law of supply with a diagram.
Answer:
1. Law of supply:
The Law of supply describes a direct relationship between the price of a good and the supply of that good.

2. Definition:
“Other things remaining the same, if the price of a commodity increases its quantity supplied increases and if the price of a commodity decreases, quantity supplied also decreases”.

3. Supply function:
Q = f (P_x, P_r, P_r T, O, E)
Q_s – Quantity supplied of x commodity
P_x – Price of x commodity
P_r – Price of related goods
P_f – Price of factors of production.
T – Technology
O – Objective of the producer.
E – The expected price of the commodity

Assumptions:

1. There is no change in the prices of factors of production and capital goods.
2. Natural resources, technology, climate, political situations, and tax policy remain unchanged.
3. Prices of substitutes are constant.

Supply schedule:
A supply schedule shows the different quantities of supply at different prices

Supply curve:
The quantum supplied is represented on X-axis. And the price of the commodity is represented on the Y-axis

As the price of the commodity increases, the quantum supplied of the commodity also increases. Thus the supply curve has a positive slope. The points such as e, d, c, b, and a on the supply curve SS, represent various quantities of different prices.

Question 3.
Explain the factors determining supply.
Answer:
1. Price of the commodity:
The higher the price larger the supply Price is the incentive for the producers and sellers to supply more.

2. Price of other commodities:
The supply of a commodity not only depends upon its price but also the prices of other commodities. For instance, if the price of commercial crops increases, the supply of food crops may decrease.

3. Price of factors:
When the input prices go up, this results in rising in cost and so supply will be affected.

4. Price expectations:
The expectation over future prices determines present supply.

5. Technology:
With the advancement in technology, production level improves average cost declines, and as a result supply level increases.

6. Natural factors:
In agriculture, natural factors like a monsoon, climate, etc., play a vital role in determining the production level.

7. Discovery of new raw materials:
The discovery of cheaper and high-quality raw materials tends to increase the supply of the product.

8. Taxes and subsidies:
Subsidies encourage the producers to produce more whereas taxes kill the ability and willingness to produce more.

9. The objective of the firm:
When the goal of the firm is sales maximization or improving market share, the supply of the product is likely to be higher.

Question 4.
Explain the characteristics of labour.
Answer:
According to Marshall, labour represents services provided by the factor labour, which helps in yielding an income to the owner of the labor-power.
Characteristics of labour:

1. Labour is the animate factor of production.
2. Labour is an active factor of production.
3. Labour implies several types it may be manual or intellectual.
4. Labour is perishable.
5. Labour is inseparable from the labourer.
6. Labour is less mobile between places and occupations.
7. Labour is a means as well as an end.
8. Labour units are heterogeneous.
9. Labour-supply determines its reward.
10. Labour has weak bargaining power.
