(a) Let x1 and x2 be normal goods. Graphically, represent the effect of an increase in the price level of x2. Show the Slutsky substitution and income effects on a clearly labelled diagram. (b) On a separate graph, show what would happen if x2 is now a Giffen good. Show the (Slutsky) substitution and income effects clearly and explain which effect outweighs the other. Note: For both parts x1 should be on the x-axis Assume the utility function to be a cobb Douglas function. Please note that you need to draw indifference curves to represent the optimal bundles.
