Use the utility function, U(X,Y) = (X- . Y ) to derive the 10 demand elasticities: M .M M M .H EXX, EXY, EYX, EYy, XX, EXY, EYx, Eyy, nx, ny H Use the Cobb-Douglas (CD) utility function, U=(X' . Y'), to answer the following: a. What is the equation of the indifference curve (IC) corresponding to U = 8? b. What is MUx? MUY? Write the expression for the MRS. d. Show that this utility function exhibits diminishing MRS. Show that this utility function satisfies monotonicity
