Suppose you have following utility function :U(x,y)=(xª + yª )a wherex > 0, y > 0 and a + 0, a < 1 The price of commodity x is P, >0 and the price of good y is P, >0. Let us denote income by M, with M> 0 a) Compute the marginal utilities of x and y. b) Write down the utility maximization problem and corresponding Lagrangian function. c) Solve for optimal bundle, x+ and y* as a function of Px, Py, and M.
