Pauline spends her income in two goods: good a and good y. Her futility function is given by u(x, y) = min{?, y}. Initially, the prices are Pr = 2 and PO = 2, but then the price of y drops to PJ = 1, while the price of a remains the same as before; that is, Pl = 2. Pauline's income is MO = 12. (a) Compute the compensating variation associated to the drop in the price of y. (b) Compute the equivalent variation associated to the drop in the price of y
