Master of Arts (Economics) Assignments (2014-15) Dear Student, As explained in the programme guide for MEC, assignments carry 30 per cent weightage in a course and it is mandatory that you have to secure at least 40 per cent marks in assignments to complete a course successfully. Note that you have to submit the assignments before appearing in Term End Examination of a course. Before attempting the assignments please read the instructions provided in the programme guide sent to you separately. There are five compulsory courses in the first year. In each course there is a Tutor Marked Assignment (TMA). You have to prepare and submit the assignments separately for each course. Make sure that you submit the assignments well in time for those courses in which you plan to appear in the Term End Examination. Submission For July 2013 session, you need to submit the assignments by March 31, 2015, and for January 2014 session by September 30, 2015 for being eligible to appear in the term-end examination. Assignments should be submitted to the Coordinator of your Study Centre. Obtain a receipt from the Study Centre towards submission. 2

An economy comprises two consumers, 1 and 2, with two consumption goods bi-cycles (b) and wheat. Both consumers have the same utility function μ,ω. Bi-cycles and wheat are produced by two firms which use only labour according to the production functions. b = l and ω 0.5 l 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. (c) Find competitive equilibrium if every consumer owns 100 units of labour and owns one firm. (d) Find the Pareto efficient allocations for this economy. 2. Assume that there are four firms supplying a homogenous product. They have identical cost functions given by C (Q) = 40 Q.

(b) Examine if Roy s law is satisfied by the consumer s demand function for y. (c) Find the expenditure function of the consumer = p. e(p,u) where price of x = 1 and price of y (d) Find the Hicksian demand function hy (p,u) for commodity y, where the price of x is 1 and the price of y is p. 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 of remaining in good health is. Let her utility function be given as U(y) =. 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? 4
