Part -1:

Question 1. An economy comprises two consumers, 1 and 2, with two consumption goods bi-cycles (b) and wheat(ω). Both consumers have the same utility function it μ(b, ω) = bω. Bi-cycles and wheat are produced by two firms which use only labour according to the production functions.

b = √l_b; and ω = 0.5√l_ω

Both firms are owned by consumer 1, and consumer 2 owns 200 units of labour.

(a) Find the production possibility frontier for this economy.

(b) Find the competitive equilibrium.

(d) Find the Pareto efficient allocations for this economy.

Question 2. Assume that there are four firms supplying a homogenous product. They have identical cost functions given by C (Q) = 40 Q. If the demand curve for the industry is given by p = 100 - Q, find the equilibrium industry output if the producers are Coumot competitors. What would be the resultant market price? What are the profits of each firm?

6. Sita expects her future earnings to be worth Rs. 100. If she falls ill, her expected future earning will be Rs. 25. There is a belief that she may fall ill with probability of while the probability 2/3 of remaining in good health is 1/3. Let her utility function be given as U(y) = Y1/2 suppose that an insurance company offers to fully insure Sita against loss of earnings caused by illness against an actuarially fair premium.

(a) Will Sita accept the insurance? Explain.

(b) What is the maximum amount that Sita would pay for the insurance?
