Question No 1(A): Ans Consider a pure-exchange economy of two individuals (A and B) and two goods (X and Y) Individual A is endowed with 5 units of good X and 3 units of good Y, while individual B with 3 and 4 units of goods X and Y respectively. Assuming utility functions of individuals A and B to be UA=XA YA 2 and UB=XB 2 YB where Xi and Yi for i= {A, B} represent individual i’s consumption of good X and Y respectively, what will be the set of Pareto optimal allocation in this economy?

Question No 1(B): Ans Determine the conditions that need to be fulfilled by an allocation to be termed as Pareto efficient allocation.

Question 2: Ans Consider a Cobb-Douglas utility function U (X, Y) = Xa Y (1- α),
Where X and y are the two goods that a consumer consumes at per unit prices of Px and Py respectively. Assuming the income of the consumer to be ₹M, determine the:

A. Marshallian demand function for goods X and Y.
B. Indirect utility function for such a consumer.
C. The maximum utility attained by the consumer where α =1/2, Px =₹ 2, Py = ₹ 8 and M= ₹ 4000.

5. (A.)Answer Differentiate between the Cournot and the Bertrand model of Oligopoly.
(B.) Answer Consider an industry with two firms 1 and 2, each producing output Q1 and Q2respectively and facing the industry demand given by P=140-Q, where P is the market price and Q represents the total industry output, that is Q= Q1 + Q2. Assume that each faces a marginal cost of ₹ 20 per unit with no fixed costs. Solve for the Cournot equilibrium in such an industry.

6. (A.) Given the Von Neumann-Morgenstern utility function of an individual, U (W) =W ½, where W stands for the amount of money. Comment upon the attitude towards the risk of such an individual with the help of a diagram.

(B.) Now suppose this individual possesses a building worth ₹1600. If the building catches fire, its value falls to ₹ 400. Let the probability of the building catching fire be ¼. On the basis of the given information, find out whether the individual would be willing to pay a risk premium of ₹ 76 to the insurance company in order to eliminate the risk associated with the factory building.
