2. Compensating Variation and Equivalent Variation (CV-EV): A consumer has u = ja (a) Derive the consumer's demands for good 1 and 2 as a function of income. M. and prices pi and p2 using the MRS and the budget line. (b) Now let A/ = 20 and initially the prices are both 1. but then p, rises to 2. Solve numeri- cally for the CV and EV associated with this change. Also show these effects on clear complete graphs. (c) Suppose you wanted to estimate the consumer surplus (CS) associated with this change without computing anything further. what would be your estimate of the CS change? Which. of CV. EV and CS are the best measure of welfare change? Why
