Good X | A B BIX B3 B2 Good Y In the above figure point A is the original consumption point. The movement from point A to point C is due to a fall in the price of good Y. Note that B1, B2, and B3 are budget constraint lines with incomes M1, M2, and M3 respectively. Also note that B2 and B3 are parallel. Calculate the compensating variation (CV). OCV = M3 _ M1 O CV = M1 - M2 O CV = M1- M3 O CV = M3 M2
