Question 2 | PYQ 2020500 words | 6 marks
State the fundamental theorems of welfare economics.
Answer
In welfare economics, there are two fundamental theorems-
- First Fundamental theorem
- This theorem is also known as “Invisible Hand Theorem”. According to this theorem, any competitive equilibrium leads to Pareto efficient allocation of finite resources. Social optimum is the main idea for market structure in t…

Question 5 | PYQ 2024500 words | 6 marks
Show the conditions that ensure efficient distribution of a given combination of products between two consumers. Would the same conditions ensure maximum equity?
Answer
Efficient allocation can be defined as the condition when no reallocation of goods can make one consumer better off without making the other worse off.
Conditions for efficient allocation
- MRS of both consumers must be equal i.e.. MRSA = MRSB. If the MRS differs between the two consumers, it implies that one consumer values the trade-off…

Question 6 | PYQ 2023500 words | 6 marks
Derive the optimality conditions in consumption in a two-commodity framework with two consumers.
Answer
In a two-commodity framework with two consumers, deriving the optimality conditions involves considering the efficient allocation of two goods (X1 and X2) between two consumers (A and B) to maximize their utility under given resource constraints.
Let UA = (XA, YA) be the utility function of consumer A.
UB = (XB, YB) be the utility funct…

Question 7 | PYQ 2023500 words | 6 marks
Show that the Pareto optimality may not ensure equitable distribution.
Answer
- Pareto optimality is a condition where resources are allocated such that it is impossible to make one individual better off without making someone else worse off.
- However, Pareto optimality does not inherently consider equity or fairness in the distribution of resources or welfare.
- This means that while a Pareto-optimal allocation ensur…

Question 8 | PYQ 2023500 words | 6 marks
Define the concept of technical efficiency as proposed by Farrell. How is different from allocative efficiency? Illustrate your answer graphically by considering a 2-input and 1-input framework.
Answer
Technical efficiency refers to the ability of a firm to produce the maximum output from a given set of inputs, or equivalently, to minimize input usage for a given level of output.
- A firm is technically efficient if it operates on the production frontier.
- Farrell՚s measure of technical efficiency is:
