Match the production functions List - I with the return to scale List - II.

Code :

It costs a firm ₹ 90 per unit to produce product A, and ₹ 60 per unit to produce B individually. If the firm can produce both products together at ₹ 160 per unit of product A and B, this exhibits signs of:

Managerial economics is concerned with which combination of the following ?

(a) Investment Analysis and Decisions

(b) Production Behaviour and Cost Analysis

(c) Input Reward Analysis and Decisions

(d) Economic Environment Analysis

Code :

When P₀ and P₁ and Q₀ and Q₁ denote before and after change in the price and quantity respectively and in both the situations, total outlay remains the same, which of the following formulae give the similar value of the arc price - elasticity of demand ?

(a) \(\dfrac{Q_{0}-Q_{1}}{P_{0}-P_{1}}\times\dfrac{P_{0}+P_{1}}{Q_{0}+Q_{1}}\)

(b) \(\dfrac{Q_{0}-Q_{1}}{P_{0}-P_{1}}\times\dfrac{P_{0}}{Q_{1}}\)

(c) \(\dfrac{Q_{0}-Q_{1}}{P_{0}-P_{1}}\times\dfrac{P_{0}}{Q_{0}}\)

(d) \(\dfrac{Q_{0}-Q_{1}}{P_{0}-P_{1}}\times\dfrac{P_{1}}{Q_{1}}\)

(e) \(\dfrac{Q_{0}-Q_{1}}{P_{0}-P_{1}}\times\dfrac{P_{1}}{Q_{0}}\)

Code :

In case the producer's equilibrium shifts to a higher isoquant due to decrease in price of an input, the curve combining the successive equilibrium positions is known as :

Which one of the following statements is not correct ?

For the following two statements of Assertion (A) and Reasoning (R), indicate the correct code :

Assertion (A) : Ridge Lines in isoquant map set the limits for the positive productivities of the respective inputs used in the production process.

Reasoning (R) : Isoquants will slope positively if the use of an input is increased beyond the limit set by the ridge lines.

Code :

Statement (I): The elasticity of factor substitution is formally defined as the percentage change in the capital-labour ratio divided by the percentage change in the marginal rate of technical substitution.

Statement (II): \(Q = K^{0.5} L^{0.3}\) is a production function where Q = output, K = units of capital and L = units of labour. This production function shows the application of increasing returns to scale.

Codes:

Law of Diminishing Return applies when the gaps among the successive ‘multiple-level of output’ isoquants:

For the following two statements of Assertion (A) and Reasoning (R) suggest the correct code:

Assertion (A): Low initial price regarded as the principal means for entering into mass market for some new products.

Reasoning (R): Firms generally enter into production of new products with excess capacity of the plant initially.

Code:

Indicate the correct code from the following types of the long run average cost curves on which the minimum average cost of production in long run can be determined:

(i) Long run average cost curve under normal production function

(ii) Long run average cost curve under linearly homogeneous production function

(iii) Planning curve

(iv) Envelope curve

Which of the following is not an attribute of production function?

Which of the following is an example of non-durable goods?
