1*. This questions examines the Lump Sum Principle on subsidies. Consider an indi-
vidual with a Cobb-Douglas utility function U(x, y) = x¹/²y¹/², and faces prices Pr, Py
with an income of $1.
(a) First, find the optimal demand for x and y and compute the indirect utility
function, V(Pa, Py, I).

(b) Now let pa 1 and p = 4. Use the expenditure function E(pr, py, U), to calculate
the extra income needed to increase the individual's utility from U = 2 to U = 3.
