Question: 2. (18 marks) Suppose you are told that a consumer has the following utility function: U(qx,qy)=e(qy)2qx1. Their income is Y, the price of good x

 2. (18 marks) Suppose you are told that a consumer has

2. (18 marks) Suppose you are told that a consumer has the following utility function: U(qx,qy)=e(qy)2qx1. Their income is Y, the price of good x is Px, and the price of goody is Py. (a) (3 marks) Show that the Marginal Rate of Substitution is the same for U(qx,qy) as the positive monotonic transformation W=ln(U(qx,qy)). What type of utility function is W(qx,qy) ? (b) (4 marks) Find qx, the demand for good x, and qy, the demand for good y. Hint: be sure to include information about where the function works. (c) (7 marks) Suppose you are given Px=$2 and Py=$18, provide a sketch of of the income-consumption curve for Y={20,25,30,35,40,45}. Be sure to label the points for each income and clearly indicate what is happening (i.e. values of qx and qy corresponding to each Y ). (d) (4 marks) Find the cross price elasticity of demand for qx and qy. Does this tell you anything about the relationship between the two goods? 2.
